The “Extinct” Grass in Britain

A The British grass interrupted brome was said to be extinct, just like the Dodo. Called interrupted brome because of its gappy seed-head, this unprepossessing grass was found nowhere else in the world, Gardening experts from the Victorian lira were first to record it. In the early 20th century, it grew far and wide across southern England. But it quickly vanished and by 1972 was nowhere to be found. Even the seeds stored at the Cambridge University Botanic Garden as an insurance policy were dead, having been mistakenly kept at room temperature. Fans of the glass were devastated.

B However, reports of its decline were not entirely correct. Interrupted brome has enjoyed a revival, one that’s not due to science. Because of the work of one gardening enthusiast, interrupted brome is thriving as a pot plant. The relaunching into the wild of Britain’s almost extinct plant has excited conservationists everywhere.

C Originally, Philip Smith didn’t know that he had the very unusual grass at his own home. When he heard about the grass becoming extinct, he wanted to do something surprising. He attended a meeting of the British Botanical Society in Manchester in 1979, and seized His opporlunity. He said that it was so disappointing to hear about the demise of the interrupted brome. “What a pity we didn’t research it further!” he added. Then. all of a sudden he displayed his pots with so called “extinct grass” lot all to see.

D Smith had kept the seeds from the last stronghold of the grass, Pamisford in 1963. It was then when the grass stalled to disappear from the wild. Smith cultivated the grass, year after year. Ultimately, it was his curiosity in the plant that saved it. not scientific or technological projects that

E For now, the bromes future is guaranteed. The seeds front Smith’s plants have beet, securely stored in the cutting edge facilities of Millennium Seed Bank at Wakehurst Place in Sussex. And living plants thrive at the botanic gardens at Kew, Edinburgh and Cambridge. This year, seeds are also saved at sites all across the country and the grass now nourishes at several public gardens too.

F The grass will now be reintroduced to the British countryside. As a part of the Species Recovery Project, the organisation English Nature will re-introduce interrupted brome into the agricultural landscape, provided willing farmers are found. Alas, the grass is neither beautiful not practical. it is undoubtedly a weed, a weed that nobody cares for these days. The brome wax probably never widespread enough to annoy farmers and today, no one would appreciate its productivity or nutritious qualities. As a grass, it leaves a lot to be desired by agriculturalists.

G Smith’s research has attempted to answer the question of where the grass came from. His research points to mutations from other weedy grasses as the most likely source. So close is the relationship that interrupted brome was originally deemed to be a mere variety of soil brome by the great Victorian taxonomist Professor Hackel. A botanist from the 19th century, Druce. had taken notes on the grass and convinced his peers that the grass deserved its own status as a species. Despite Druce growing up in poverty and his self-taught profession, he became the leading botanist of his time.

H Where the grass came from may be clear, but the timing of its birth may be tougher to find out. A clue lies in its penchant for growing as a weed in fields shared with a fodder crop, in particular nitrogen-fixing legumes such as sainfoin, lucerne or clover. According to agricultural historian Joan Thirsk. the humble sainfoin and its company were first noticed in Britain in the early 17th century. Seeds brought in from the Continent were sown in pastures to feed horses and other livestock. However, back then, only a few enthusiastic gentlemen were willing to use the new crops for their prized horses.

I Not before too long though, the need to feed the parliamentary armies in Scotland, England and behind was more pressing than ever. farmers were forced to produce more bread, cheese and beer. And by 1650 the legumes were increasingly introduced into arable rotations, to serve as green nature to boost grain yields. A bestseller of its day, Nathaniel Fiennes’s Sainfoin Improved, published in 1671, helped to spread the word. With the advent of sainfoin, clover and lucerne. Britain’s very own rogue grass had suddenly at rivet.

J Although the credit for the discovery of interrupted brome goes to a Miss A. M. Barnard, who collected the first specimens at Odsey, Bedfordshire, in 1849, the grass had probably lurked undetected in the English countryside for at least a hundred years. Smith thinks the plant- the world’s version of the Dodo probably evolved in the late 17th or early 18th century, once sainfoin became established. Due mainly to the development of the motor car and subsequent decline of fodder crops for horses, the brome declined rapidly over the 20th century. Today, sainfoin has almost disappeared from the countryside, though occasionally its colourful flowers are spotted in lowland nature reserves. More recently artificial fertilizers have made legume rotations unnecessary.

K The close relationship with out-of-fashion crops spells trouble for those seeking to re-establish interrupted brome in today’s countryside. Much like the once common arable weeds, such as the corncockle, its seeds cannot survive long in the soil. Each spring, the brome relied on farmers to resow its seeds; in the days before weed killers and advanced seed sieves, an ample supply would have contaminated supplies of crop seed. However fragile seeds are not the brome’s only problem: this species is also unwilling to release its seeds as they ripen. According to Smith. The grass will struggle to survive even in optimal conditions. It would be very difficult to thrive amongst its more resilient competitors found in today’s improved agricultural landscape

L Nonetheless, interrupted brome’s reluctance to thrive independently may have some benefits. Any farmer willing to foster this unique contribution to the world’s flora can rest assured that the grass will never become an invasive pest. Restoring interrupted brome to its rightful home could bring other benefits too, particularly if this strange species is granted recognition as a national treasure. Thanks to British farmers, interrupted brome was given the chance to evolve in the first place. Conservationists would like to see the grass grow once again in its natural habitat and perhaps, one day, seeing the grass become a badge of honour for a new generation of environmentally conscious farmers.

Keep the Water Away

A Last winter’s floods on the rivers of central Europe were among the worst since the Middle Ages, and as winter storms return, the spectre of floods is returning too. Just weeks ago, the river Rhone in south-east France burst its banks, driving 15,000 people from their homes, and worse could be on the way. Traditionally, river engineers have gone for Plan A: get rid of the water fast, draining it off the land and down to the sea in tall-sided rivers re-engineered as high-performance drains. But however big they dug city drains, however wide and straight they made the rivers, and however high they built the banks, the floods kept coming back to taunt them, from the Mississippi to the Danube. Arid when the floods came, they seemed to be worse than ever. No wonder engineers are turning to Plan B: sap the water’s destructive strength by dispersing it into fields, forgotten lakes, flood plains and aquifers.

B Back in the days when rivers took a more tortuous path to the sea, flood waters lost impetus and volume while meandering across flood plains and idling through wetlands and inland deltas. But today the water tends to have an unimpeded journey to the sea. And this means that when it rains in the uplands, the water comes down all at once. Worse, whenever we close off more flood plains, the river’s flow farther downstream becomes more violent and uncontrollable. Dykes are only as good as their weakest link—-and the water will unerringly find it. By trying to turn the complex hydrology of rivers into the simple mechanics of a water pipe, engineers have often created danger where they promised safety, and intensified the floods they meant to end. Take the Rhine, Europe’s most engineered river. For two centuries, German engineers have erased its backwaters and cut it off from its flood plain.

C Today, the river has lost 7 percent of its original length and runs up to a third faster. When it rains hard in the Alps, the peak flows from several tributaries coincide in the main river, where once they arrived separately. And with four-fifths of the lower Rhine’s flood plain barricaded off, the waters rise ever higher. The result is more frequent flooding that does ever-greater damage to the homes, offices and roads that sit on the flood plain. Much the same has happened in the US on the mighty Mississippi, which drains the world’s second largest river catchment into the Gulf of Mexico.

D The European Union is trying to improve rain forecasts and more accurately model how intense rains swell rivers. That may help cities prepare, but it won’t stop the floods. To do that, say hydrologists, you need a new approach to engineering not just rivers, but the whole landscape. The UK’s Environment Agency -which has been granted an extra £150 million a year to spend in the wake of floods in 2000 that cost the country £1 billion- puts it like this: “The focus is now on working with the forces of nature. Towering concrete walks are out, and new wetlands : are in.” To help keep London’s feet dry, the agency is breaking the Thames’s banks upstream and reflooding 10 square kilometres of ancient flood plain at Otmoor outside Oxford. Nearer to London it has spent £100 million creating new wetlands and a relief channel across 16 kilometres of flood plain to protect the town of Maidenhead, as well as the ancient playing fields of Eton College. And near the south coast, the agency is digging out channels to reconnect old meanders on the river Cuckmere in East Sussex that were cut off by flood banks 150 years ago.

E The same is taking place on a much grander scale in Austria, in one of Europe’s largest river restorations to date. Engineers are regenerating flood plains along 60 kilometres of the river Drava as it exits the Alps. They are also widening the river bed and channelling it back into abandoned meanders, oxbow lakes and backwaters overhung with willows. The engineers calculate that the restored flood plain can now store up to 10 million cubic metres of flood waters and slow storm surges coming out of the Alps by more than an hour, protecting towns as far downstream as Slovenia and Croatia.

F “Rivers have to be allowed to take more space. They have to be turned from flood-chutes into flood-foilers,” says Nienhuis. And the Dutch, for whom preventing floods is a matter of survival, have gone furthest. A nation built largely on drained marshes and seabed had the fright of its life in 1993 when the Rhine almost overwhelmed it. The same happened again in 1995, when a quarter of a million people were evacuated from the Netherlands. But a new breed of “soft engineers” wants our cities to become porous, and Berlin is their shining example. Since reunification, the city’s massive redevelopment has been governed by tough new rules to prevent its drains becoming overloaded after heavy rains. Harald Kraft, an architect working in the city, says: “We now see rainwater as a resource to be kept rather than got rid of at great cost.” A good illustration is the giant Potsdamer Platz, a huge new commercial redevelopment by Daimler Chrysler in the heart of the city.

G Los Angeles has spent billions of dollars digging huge drains and concreting river beds to carry away the water from occasional intense storms. The latest plan is to spend a cool $280 million raising the concrete walls on the Los Angeles river by another 2 metres. Yet many communities still flood regularly. Meanwhile this desert city is shipping in water from hundreds of kilometres away in northern California and from the Colorado river in Arizona to fill its taps and swimming pools, and irrigate its green spaces. It all sounds like bad planning. “In LA we receive half the water we need in rainfall, and we throw it away. Then we spend hundreds of millions to import water,” says Andy Lipkis, an LA environmentalist, along with citizen groups like Friends of the Los Angeles River and Unpaved LA, want to beat the urban flood hazard and fill the taps by holding onto the city’s flood water. And it’s not just a pipe dream. The authorities this year launched a $100 million scheme to road-test the porous city in one flood-hit community in Sun Valley. The plan is to catch the rain that falls on thousands of driveways, parking lots and rooftops in the valley. Trees will soak up water from parking lots. Homes and public buildings will capture roof water to irrigate gardens and parks. And road drains will empty into old gravel pits and other leaky places that should recharge the city’s underground water reserves. Result: less flooding and more water for the city. Plan B says every city should be porous, every river should have room to flood naturally and every coastline should be left to build its own defences. It sounds expensive and utopian, until you realise how much we spend trying to drain cities and protect our watery margins -and how bad we are at it.

What Do Babies Know?

As Daniel Haworth is settled into a high chair and wheeled behind a black screen, a sudden look of worry furrows his 9-month-old brow. His dark blue eyes dart left and right in search of the familiar reassurance of his mother’s face. She calls his name and makes soothing noises, but Daniel senses something unusual is happening. He sucks his fingers for comfort, but, finding no solace, his month crumples, his body stiffens, and he lets rip an almighty shriek of distress. This is the usual expression when babies are left alone or abandoned. Mom picks him up, reassures him, and two minutes later, a chortling and alert Daniel returns to the darkened booth behind the screen and submits himself to baby lab, a unit set up in 2005 at the University of Manchester in northwest England to investigate how babies think.

Watching infants piece life together, seeing their senses, emotions and motor skills take shape, is a source of mystery and endless fascination—at least to parents and developmental psychologists. We can decode their signals of distress or read a million messages into their first smile. But how much do we really know about what’s going on behind those wide, innocent eyes? How much of their understanding of and response to the world comes preloaded at birth? How much is built from scratch by experience? Such are the questions being explored at baby lab. Though the facility is just 18 months old and has tested only 100 infants, it’s already challenging current thinking on what babies know and how they come to know it.

Daniel is now engrossed in watching video clips of a red toy train on a circular track. The train disappears into a tunnel and emerges on the other side. A hidden device above the screen is tracking Daniel’s eyes as they follow the train and measuring the diametre of his pupils 50 times a second. As the child gets bored—or “habituated”, as psychologists call the process— his attention level steadily drops. But it picks up a little whenever some novelty is introduced. The train might be green, or it might be blue. And sometimes an impossible thing happens— the train goes into the tunnel one color and comes out another.

Variations of experiments like this one, examining infant attention, have been a standard tool of developmental psychology ever since the Swiss pioneer of the field, Jean Piaget, started experimenting on his children in the 1920s. Piaget’s work led him to conclude that infants younger than 9 months have no innate knowledge of how the world works or any sense of “object permanence” (that people and things still exist even when they’re not seen). Instead, babies must gradually construct this knowledge from experience. Piaget’s “constructivist” theories were massively influential on postwar educators and psychologist, but over the past 20 years or so they have been largely set aside by a new generation of “nativist” psychologists and cognitive scientists whose more sophisticated experiments led them to theorise that infants arrive already equipped with some knowledge of the physical world and even rudimentary programming for math and language. Baby lab director Sylvain Sirois has been putting these smart-baby theories through a rigorous set of tests. His conclusions so far tend to be more Piagetian: “Babies,” he says, “know nothing.”

What Sirois and his postgraduate assistant Lain Jackson are challenging is the interpretation of a variety of classic experiments begun in the mid-1980s in which babies were shown physical events that appeared to violate such basic concepts as gravity, solidity and contiguity. In one such experiment, by University of Illinois psychologist Renee Baillargeon, a hinged wooden panel appeared to pass right through a box. Baillargeon and M.I.T’s Elizabeth Spelke found that babies as young as 3 1/2 months would reliably look longer at the impossible event than at the normal one. Their conclusion: babies have enough built-in knowledge to recognise that something is wrong.

Sirois does not take issue with the way these experiments were conducted. “The methods are correct and replicable,” he says, “it’s the interpretation that’s the problem.” In a critical review to be published in the forthcoming issue of the European Journal of Developmental Psychology, he and Jackson pour cold water over recent experiments that claim to have observed innate or precocious social cognition skills in infants. His own experiments indicate that a baby’s fascination with physically impossible events merely reflects a response to stimuli that are novel. Data from the eye tracker and the measurement of the pupils (which widen in response to arousal or interest) show that impossible events involving familiar objects are no more interesting than possible events involving novel objects. In other words, when Daniel had seen the red train come out of the tunnel green a few times, he gets as bored as when it stays the same color. The mistake of previous research, says Sirois, has been to leap to the conclusion that infants can understand the concept of impossibility from the mere fact that they are able to perceive some novelty in it. “The real explanation is boring,” he says.

So how do babies bridge the gap between knowing squat and drawing triangles—a task Daniel’s sister Lois, 2 1/2, is happily tackling as she waits for her brother? “Babies have to learn everything, but as Piaget was saying, they start with a few primitive reflexes that get things going,” said Sirois. For example, hardwired in the brain is an instinct that draws a baby’s eyes to a human face. From brain imaging studies we also know that the brain has some sort of visual buffer that continues to represent objects after they have been removed—a lingering perception rather than conceptual understanding. So when babies encounter novel or unexpected events, Sirois explains, “there’s a mismatch between the buffer and the information they’re getting at that moment. And what you do when you’ve got a mismatch is you try to clear the buffer. And that takes attention.” So learning, says Sirois, is essentially the laborious business of resolving mismatches. “The thing is, you can do a lot of it with this wet sticky thing called a brain. It’s a fantastic, statistical-learning machine”. Daniel, exams ended, picks up a plastic tiger and, chewing thoughtfully upon its heat, smiles as if to agree.

Radiocarbon Dating – The Profile of Nancy Athfield

Have you ever picked up a small stone off the ground and wondered how old it was? Chances are, that stone has been around many more years than your own lifetime. Many scientists share this curiosity about the age of inanimate objects like rocks, fossils and precious stones. Knowing how old an object is can provide valuable information about our prehistoric past. In most societies, human beings have kept track of history through writing. However, scientists are still curious about the world before writing, or even the world before humans. Studying the age of objects is our best way to piece together histories of our pre-historic past. One such method of finding the age of an object is called radiocarbon dating. This method can find the age of any object based on the kind of particles and atoms that are found inside of the object. Depending on what elements the object is composed of, radiocarbon can be a reliable way to find an object’s age. One famous specialist in this method is the researcher Nancy Athfield. Athfield studied the ancient remains found in the country of Cambodia. Many prehistoric remains were discovered by the local people of Cambodia. These objects were thought to belong to some of the original groups of humans that first came to the country of Cambodia. The remains had never been scientifically studied, so Nancy was greatly intrigued by the opportunity to use modern methods to discover the true age of these ancient objects.

Athfield had this unique opportunity because her team, comprised of scientists and filmmakers, were in Cambodia working on a documentary. The team was trying to discover evidence to prove a controversial claim in history: that Cambodia was the resting place for the famous royal family of Angkor. At that time, written records and historic accounts conflicted on the true resting place. Many people across the world disagreed over where the final resting place was. For the first time, Athfield and her team had a chance to use radiocarbon dating to find new evidence. They had a chance to solve the historic mystery that many had been arguing over for years.

Athfield and her team conducted radiocarbon dating of many of the ancient objects found in the historic site of Angkor Wat. Nancy found the history of Angkor went back to as early as 1620. According to historic records, the remains of the Angkor royal family were much younger than that, so this evidence cast a lot of doubt as to the status of the ancient remains. The lesearch ultimately raised more questions. If the remains were not of the royal family, then whose remains were being kept in the ancient site? Athfield’s team left Cambodia with more questions unanswered. Since Athfield’s team studied the remains, new remains have been unearthed at the ancient site of Angkor Wat, so it is possible that these new remains could be the true remains of the royal family. Nancy wished to come back to continue her research one day.

In her early years, the career of Athfield was very unconventional. She didn’t start her career as a scientist. At the beginning, she would take any kind of job to pay her bills. Most of them were low-paying jobs or brief Community service opportunities. She worked often but didn’t know what path she would ultimately take. But eventually, her friend suggested that Athfield invest in getting a degree. The friend recommended that Athfield attend a nearby university. Though doubtful of her own qualifications, she applied and was eventually accepted by the school. It was there that she met Willard Libby, the inventor of radiocarbon dating. She took his class and soon had the opportunity to complete hands-on research. She soon realised that science was her passion. After graduation, she quickly found a job in a research institution.

After college, Athfield’s career in science blossomed. She eventually married, and her husband landed a job at the prestigious organisation GNN. Athfield joined her husband in the same organisation, and she became a lab manager in the institution. She earned her PhD in scientific research, and completed her studies on a kind of rat when it first appeared in New Zealand. There, she created original research and found many flaws in the methods being used in New Zealand laboratories. Her research showed that the subject’s diet led to the fault in the earlier research. She was seen as an expert by her peers in New Zealand, and her opinion and expertise were widely respected. She had come a long way from her old days of working odd jobs. It seemed that Athfield’s career was finally taking off.

But Athfield’s interest in scientific laboratories wasn’t her only interest. She didn’t settle down in New Zealand. Instead, she expanded her areas of expertise. Athfield eventually joined the field of Anthropology, the study of human societies, and became a well-qualified archaeologist. It was during her blossoming career as an archaeologist that Athfield became involved with the famous Cambodia project. Even as the filmmakers ran out of funding and left Cambodia, Athfield continued to stay and continue her research.

In 2003, the film was finished in uncertain conclusions, but Nancy continued her research on the ancient ruins of Angkor Wat. This research was not always easy. Her research was often delayed by lack of funding, and government paperwork. Despite her struggles, she committed to finishing her research. Finally, she made a breakthrough. Using radiocarbon dating, Athfield completed a database for the materials found in Cambodia. As a newcomer to Cambodia, she lacked a complete knowledge of Cambodian geology, which made this feat even more difficult. Through steady determination and ingenuity, Athfield finally completed the database. Though many did not believe she could finish, her research now remains an influential and tremendous contribution to geological sciences in Cambodia. In the future, radiocarbon dating continues to be a valuable research skill. Athfield will be remembered as one of the first to bring this scientific method to the study of the ancient ruins of Angkor Wat.

Stress of Workplace

A How busy is too busy? For some it means having to miss the occasional long lunch; for others it means missing lunch altogether. For a few, it is hot being able to take a “sickie” once a month. Then there is a group of people for whom working every evening and weekend is normal, and franticness is the tempo of their lives. For most senior executives, workloads swing between extremely busy and frenzied. The vice-president of the management consultancy AT Kearney and its head of telecommunications for the Asia-Pacific region, Neil Plumridge, says his work weeks vary from a “manageable” 45 hours to 80 hours, but average 60 hours.

B Three warning signs alert Plumridge about his workload: sleep, scheduling and family. He knows he has too much on when he gets less than six hours of sleep for three consecutive nights; when he is constantly having to reschedule appointments; “and the third one is on the family side”, says Plumridge, the father of a three-year-old daughter, and expecting a second child in October. “If I happen to miss a birthday or anniversary, I know things are out of control.” Being “too busy” is highly subjective. But for any individual, the perception of being too busy over a prolonged period can start showing up as stress: disturbed sleep, and declining mental and physical health. National workers’ compensation figures show stress causes the most lost time of any workplace injury. Employees suffering stress are off work an average of 16.6 weeks. The effects of stress are also expensive. Comcare, the Federal Government insurer, reports that in 2003-04, claims for psychological injury accounted for 7% of claims but almost 27% of claim costs. Experts say the key to dealing with stress is not to focus on relief—a game of golf or a massage-—but to reassess workloads. Neil Plumridge says he makes it a priority to work out what has to change; that might mean allocating extra resources to a job, allowing more time or changing expectations. The decision may take several days. He also relies on the advice of colleagues, saying his peers coach each other with business problems. “Just a fresh pair of eyes over an issue can help,” he says.

C Executive stress is not confined to big organisations. Vanessa Stoykov has been running her own advertising and public relations business for seven years, specialising in work for financial and professional services firms. Evolution Media has grown so fast that it debuted on the BRW Fast 100 list of fastest-growing small enterprises last year—just after Stoykov had her first child. Stoykov thrives on the mental stimulation of running her own business. “Like everyone, I have the occasional day when I think my head’s going to blow off,” she says. Because of the growth phase the business is in, Stoykov has to concentrate on short-term stress relief—weekends in the mountains, the occasional “mental health” day—rather than delegating more work. She says: “We’re hiring more people, but you need to train them, teach them about the culture and the clients, so it’s actually more work rather than less.”

D Identify the causes: Jan Eisner, Melbourne psychologist who specialises in executive coaching, says thriving on a demanding workload is typical of senior executives and other high-potential business adrenalin periods followed by quieter patches, while others thrive under sustained pressure. “We could take urine and blood hormonal measures and pass a judgement of whether someone’s physiologically stressed or not,” she says. “But that’s not going to give us an indicator of what their experience of stress is, and what the emotional and cognitive impacts of stress are going to be.”

E Eisner’s practice is informed by a movement known as positive psychology, a school of thought that argues “positive” experiences—feeling engaged, challenged, and that one is making a contribution to something meaningful—do not balance out negative ones such as stress; instead, they help people increase their resilience over time. Good stress, or positive experiences of being challenged and rewarded, is thus cumulative in the same way as bad stress. Eisner says many of the senior business people she coaches are relying more on regulating bad stress through methods such as meditation and yoga. She points to research showing that meditation can alter the biochemistry of the brain and actually help people “retrain” the way their brains and bodies react to stress. “Meditation and yoga enable you to shift the way that your brain reacts, so if you get proficient at it you’re in control.”

F Recent research, such as last year’s study of public servants by the British epidemiologist Sir Michael Marmot, shows the most important predictor of stress is the level of job control a person has. This debunks the theory that stress is the prerogative of high-achieving executives with type-A personalities and crazy working hours. Instead, Marmot’s and other research reveals they have the best kind of job: one that combines high demands (challenging work) with high control (autonomy). “The worst jobs are those that combine high demands and low control. People with demanding jobs but little autonomy have up to four times the probability of depression and more than double the risk of heart disease,” LaMontagne says. “Those two alone count for an enormous part of chronic diseases, and they represent a potentially preventable part.” Overseas, particularly in Europe, such research is leading companies to redesign organisational practices to increase employees’ autonomy, cutting absenteeism and lifting productivity.

G The Australian vice-president of AT Kearney, Neil Plumridge says, “Often stress is caused by our setting unrealistic expectations of ourselves. I’ll promise a client I’ll do something tomorrow, and then [promise] another client the same thing, when I really know it’s not going to happen. I’ve put stress on myself when I could have said to the clients: Why don’t I give that to you in 48 hours?’ The client doesn’t care.” Overcommitting is something people experience as an individual problem. We explain it as the result of procrastination or Parkinson’s law: that work expands to fdl the time available. New research indicates that people may be hard-wired to do it.

H A study in the February issue of the Journal of Experimental Psychology shows that people always believe they will be less busy in the future than now. This is a misapprehension, according to the authors of the report, Professor Gal Zauberman, of the University of North Carolina, and Professor John Lynch, of Duke University. “On average, an individual will be just as busy two weeks or a month from now as he or she is today. But that is not how it appears to be in everyday life,” they wrote. “People often make commitments long in advance that they would never make if the same commitments required immediate action. That is, they discount future time investments relatively steeply.” Why do we perceive a greater “surplus” of time in the future than in the present? The researchers suggest that people underestimate completion times for tasks stretching into the future, and that they are bad at imagining future competition for their time.

Robert Louis Stevenson

A Scottish novelist, poet, essayist, and travel writer, Robert Louis Stevenson was born at 8 Howard Place, Edinburgh, Scotland, on 13 November 1850. It has been more than 100 years since his death. Stevenson was a writer who caused conflicting opinions about his works. On one hand, he was often highly praised for his expert prose and style by many English-language critics. On the other hand, others criticised the religious themes in his works, often misunderstanding Stevenson’s own religious beliefs. Since his death a century before, critics and biographers have disagreed on the legacy of Stevenson’s writing. Two biographers, KF and CP , wrote a biography about Stevenson with a clear focus. They chose not to criticise aspects of Stevenson’s personal life. Instead, they focused on his writing, and gave high praise to his writing style and skill.

The literary pendulum has swung these days. Different critics have different opinions towards Robert Louis Stevenson’s works. Though today, Stevenson is one of the most translated authors in the world, his works have sustained a wide variety of negative criticism throughout his life. It was like a complete reversal of polarity—from highly positive to slightly less positive to clearly negative; after being highly praised as a great writer, he became an example of an author with corrupt ethics and lack of moral. Many literary critics passed his works off as children’s stories or horror stories, and thought to have little social value in an educational setting. Stevenson’s works were often excluded from literature curriculum because of its controversial nature. These debates remain, and many critics still assert that despite his skill, his literary works still lack moral value.

One of the main reasons why Stevenson’s literary works attracted so much criticism was due to the genre of his writing. Stevenson mainly wrote adventure stories, which was part of a popular and entertaining writing fad at the time. Many of us believe adventure stories are exciting, offers engaging characters, action, and mystery but ultimately can’t teach moral principles. The plot points are one-dimensional and rarely offer a deeper moral meaning, instead focusing on exciting and shocking plot twists and thrilling events. His works were even criticised by fellow authors. Though Stevenson’s works have deeply influenced Oscar Wilde, Wilde often joked that Stevenson would have written better works if he wasn’t born in Scotland. Other authors came to Stevenson’s defence, including Galsworthy who claimed that Stevenson is a greater writer than Thomas Hardy.

Despite Wilde’s criticism, Stevenson’s Scottish identity was an integral part of his written works. Although Stevenson’s works were not popular in Scotland when he was alive, many modern Scottish literary critics claim that Sir Walter Scott and Robert Louis Stevenson are the most influential writers in the history of Scotland. While many critics exalt Sir Walter Scott as a literary genius because of his technical ability, others argue that Stevenson deserves the same recognition for his natural ability to capture stories and characters in words. Many of Scott’s works were taken more seriously as literature for their depth due to their tragic themes, but fans of Stevenson praise his unique style of story-telling and capture of human nature. Stevenson’s works, unlike other British authors, captured the unique day to day life of average Scottish people. Many literary critics point to this as a flaw of his works. According to the critics, truly important literature should transcend local culture and stories. However, many critics praise the local taste of his literature. To this day, Stevenson’s works provide valuable insight to life in Scotland during the 19th century.

Despite much debate of Stevenson’s writing topics, his writing was not the only source of attention for critics. Stevenson’s personal life often attracted a lot of attention from his fans and critics alike. Some even argue that his personal life eventually outshone his writing. Stevenson had been plagued with health problems his whole life, and often had to live in much warmer climates than the cold, dreary weather of Scotland in order to recover. So he took his family to a south pacific island Samoa, which was a controversial decision at that time. However, Stevenson did not regret the decision. The sea air and thrill of adventure complimented the themes of his writing, and for a time restored his health. From there, Stevenson gained a love of travelling, and for nearly three years he wandered the eastern and central Pacific. Much of his works reflected this love of travel and adventure that Stevenson experienced in the Pacific islands. It was as a result of this biographical attention that the feeling grew that interest in Stevenson’s life had taken the place of interest in his works. Whether critics focus on his writing subjects, his religious beliefs, or his eccentric lifestyle of travel and adventure, people from the past and present have different opinions about Stevenson as an author. Today, he remains a controversial yet widely popular figure in Western literature.

The Extraordinary Watkin Tench

At the end of 18th century, life for the average British citizen was changing. The population grew as health and industrialization took hold of the country. However, land and resources were limited. Families could not guarantee jobs for all of their children. People who were poor or destitute had little option. To make things worse, the rate of people who turned to crime to make a living increased. In Britain, the prisons were no longer large enough to hold the convicted people of this growing criminal class. Many towns and governments were at a loss as to what to do. However, another phenomenon that was happening in the 18th century was I exploration of other continents. There were many ships looking for crew members who would risk a month-long voyage across a vast ocean. This job was risky and dangerous, so few would willingly choose it. However, with so many citizens without jobs or with criminal convictions, they had little choice. One such member of this new lower class of British citizens was Watkin Tench. Between 1788 and 1868, approximately 161,700 convicts were transported to the Australian colonies of New South Wales, Van Diemen’s land and Western Australia. Tench was one of these unlucky convicts to sign onto a dangerous journey. When his ship set out in 1788, he signed a three years’ service to the First Fleet.

Apart from his years in Australia, people knew little about his life back in Britain. It was said he was born on 6 October 1758 at Chester in the county of Cheshire in England. He came from a decent background. Tench was a son of Fisher Tench, a dancing master who ran a boarding school in the town and Margaritta Tarleton of the Liverpool Tarletons. He grew up around a finer class of British citizens, and his family helped instruct the children of the wealthy in formal dance lessons. Though we don’t know for sure how Tench was educated in this small British town, we do know that he was well educated. His diaries from his travels to Australia are written in excellent English, a skill that not everyone was lucky to possess in the 18th century. Aside from this, we know little of Tench’s beginnings. We don’t know how he ended up convicted of a crime. But after he started his voyage, his life changed dramatically.

During the voyage, which was harsh and took many months, Tench described landscape of different places. While sailing to Australia, Tench saw landscapes that were unfamiliar and new to him. Arriving in Australia, the entire crew was uncertain of what was to come in their new life. When they arrived in Australia, they established a British colony. Governor Philip was vested with complete authority over the inhabitants of the colony. Though still a young man, Philip was enlightened for his age. From stories of other British colonies, Philip learnt that conflict with the original peoples of the land was often a source of strife and difficulties. To avoid this, Philip’s personal intent was to establish harmonious relations with local Aboriginal people. But Philip’s job was even more difficult considering his crew. Other colonies were established with middle-class merchants and craftsmen. His crew were convicts, who had few other skills outside of their criminal histories. Along with making peace with the Aboriginal people, Philip also had to try to reform as well as discipline the convicts of the colony.

From the beginning, Tench stood out as different from the other convicts. During his initial time in Australia, he quickly rose in his rank, and was given extra power and responsibility over the convicted crew members. However, he was also still very different from the upper-class rulers who came to rule over the crew. He showed humanity towards the convicted workers. He didn’t want to treat them as common criminals, but as trained military men. Under Tench’s authority, he released the convicts’ chains which were used to control them during the voyage. Tench also showed mercy towards the Aboriginal people. Governor Philip often pursued violent solutions to conflicts with the Aboriginal peoples. Tench disagreed strongly with this method. At one point, he was unable to follow the order given by the Governor Philip to punish the ten Aboriginals.

When they first arrived, Tench was fearful and contemptuous towards the Aboriginals, because the two cultures did not understand each other. However, gradually he got to know them individually and became close friends with them. Tench knew that the Aboriginal people would not cause them conflict if they looked for a peaceful solution. Though there continued to be conflict and violence, Tench’s efforts helped establish a more peaceful negotiation between the two groups when they settled territory and land-use issues.

Meanwhile, many changes were made to the new colony. The Hawkesbury River was named by Governor Philip in June 1789. Many native bird species to the river were hunted by travelling colonists. The colonists were having a great impact on the land and natural resources. Though the colonists had made a lot of progress in the untamed lands of Australia, there were still limits. The convicts were notoriously ill-informed about Australian geography, as was evident in the attempt by twenty absconders to walk from Sydney to China in 1791, believing: “China might be easily reached, being not more than a hundred miles distant, and separated only by a river.” In reality, miles of ocean separated the two.

Much of Australia was unexplored by the convicts. Even Tench had little understanding of what existed beyond the established lines of their colony. Slowly, but surely, the colonists expanded into the surrounding area. A few days after arrival at Botany Bay, their original location, the fleet moved to the more suitable Port Jackson where a settlement was established at Sydney Cove on 26 January 1788. This second location was strange and unfamiliar, and the fleet was on alert for any kind of suspicious behaviors. Though Tench had made friends in Botany Bay with Aboriginal peoples, he could not be sure this new land would be uninhabited. He recalled the first time he stepped into this unfamiliar ground with a boy who helped Tench navigate. In these new lands, he met an old Aboriginal.

Are Artists Liars?

A Shortly before his death, Marlon Brando was working on a series of instructional videos about acting, to he called “Lying for a Iiving”. On the surviving footage, Brando can he seen dispensing gnomic advice on his craft to a group of enthusiastic, if somewhat bemused, Hollywood stars, including Leonardo Di Caprio and Sean Penn. Brando also recruited random people from the Los Angeles street and persuaded them to improvise (the footage is said to include a memorable scene featuring two dwarves and a giant Samoan). “If you can lie, you can act.” Brando told Jod Kaftan, a writer for Rolling Stone and one of the few people to have viewed the footage. “Are you good at lying?” asked Kaftan. “Jesus.” said Brando, “I’m fabulous at it”.

B Brando was not the first person to note that the line between an artist and a liar is a line one. If art is a kind of lying, then lying is a form of art, albeit of a lower order-as Oscar Wilde and Mark Twain have observed. Indeed, lying and artistic storytelling spring from a common neurological root-one that is exposed in the cases of psychiatric patients who suffer from a particular kind of impairment. Both liars and artists refuse to accept the tyranny of reality. Both carefully craft stories that are worthy of belief – a skill requiring intellectual sophistication, emotional sensitivity and physical self-control (liars are writers and performers of their own work). Such parallels are hardly coincidental, as I discovered while researching my book on lying.

C A case study published in 1985 by Antonio Damasio, a neurologist, tells the story of a middle-aged woman with brain damage caused by a series of strokes. She retained cognitive abilities, including coherent speech, but what she actually said was rather unpredictable. Checking her knowledge of contemporary events, Damasio asked her about the Falklands War. In the language of psychiatry, this woman was “confabulating”. Chronic confabulation is a rare type of memory problem that affects a small proportion of brain damaged people. In the literature it is defined as “the production of fabricated, distorted or misinterpreted memories about oneself or the world, without the conscious intention to deceive”. Whereas amnesiacs make errors of omission, there are gaps in their recollections they find impossible to fill – confabulators make errors of commission: they make tilings up. Rather than forgetting, they are inventing. Confabulating patients are nearly always oblivious to their own condition, and will earnestly give absurdly implausible explanations of why they’re in hospital, or talking to a doctor. One patient, asked about his surgical sear, explained that during the Second World War he surprised a teenage girl who shot him three times in the head, killing him, only for surgery to bring him back to life. The same patient, when asked about his family, described how at various times they had died in his arms, or had been killed before his eyes. Others tell yet more fantastical tales, about trips to the moon, fighting alongside Alexander in India or seeing Jesus on the Cross. Confabulators aren’t out to deceive. They engage in what Morris Moseovitch, a neuropsychologist, calls “honest lying”. Uncertain and obscurely distressed by their uncertainty, they are seized by a “compulsion to narrate”: a deep-seated need to shape, order and explain what they do not understand. Chronic confabulators are often highly inventive at the verbal level, jamming together words in nonsensical but suggestive ways: one patient, when asked what happened to Queen Marie Antoinette of France, answered that she had been “suicided” by her family. In a sense, these patients are like novelists, as described by Henry James: people on whom “nothing is wasted”. Unlike writers, however, they have little or no control over their own material.

D The wider significance of this condition is what it tells us about ourselves. Evidently, there is a gushing river of verbal creativity in the normal human mind, from which both artistic invention and lying are drawn. We are born storytellers, spinning, narrative out of our experience and imagination, straining against the leash that keeps us tethered to reality. This is a wonderful thing; it is what gives us out ability to conceive of alternative futures and different worlds. And it helps us to understand our own lives through the entertaining stories of others. But it can lead us into trouble, particularly when we try to persuade others that our inventions are real. Most of the time, as our stories bubble up to consciousness, we exercise our cerebral censors, controlling which stories we tell, and to whom. Yet people lie for all sorts of reasons, including the fact that confabulating can be dangerously fun.

E During a now-famous libel case in 1996, Jonathan Aitken, a former cabinet minister, recounted a tale to illustrate the horrors he endured after a national newspaper tainted his name. The case, which stretched on for more than two years, involved a series of claims made by the Guardian about Aitken’s relationships with Saudi arms dealers, including meetings he allegedly held with them on a trip to Paris while he was a government minister. Whitt amazed many in hindsight was the sheer superfluity of the lies Aitken told during his testimony. Aitken’s case collapsed in June 1997, when the defence finally found indisputable evidence about his Paris trip. Until then, Aitken’s charm, fluency and flair for theatrical displays of sincerity looked as if they might bring him victory, they revealed that not only was Aitken’s daughter not with him that day (when he was indeed doorstepped), but also that the minister had simply got into his car and drove off, with no vehicle in pursuit.

F Of course, unlike Aitken, actors, playwrights and novelists are not literally attempting to deceive us, because the rules are laid out in advance: come to the theatre, or open this book, and we’ll lie to you. Perhaps this is why we fell it necessary to invent art in the first place: as a safe space into which our lies can be corralled, and channeled into something socially useful. Given the universal compulsion to tell stories, art is the best way to refine and enjoy the particularly outlandish or insight till ones. But that is not the whole story. The key way in which artistic “lies” differ from normal lies, and from the “honest lying” of chronic confabulators, is that they have a meaning and resonance beyond their creator. The liar lies on behalf of himself; the artist tells lies on behalf of everyone. If writers have a compulsion to narrate, they compel themselves to find insights about the human condition. Mario Vargas Llosa has written that novels “express a curious truth that can only he expressed in a furtive and veiled fashion, masquerading as what it is not.” Art is a lie whose secret ingredient is truth.

Theory or Practice? —What is the point of research carried out by biz schools?

Students go to universities and other academic institutions to prepare for their future. We pay tuition and struggle through classes in the hopes that we can find a fulfilling and exciting career. But the choice of your university has a large influence on your future. How can you know which university will prepare you the best for your future? Like other academic institutions, busi­ness schools are judged by the quality of the research carried out by their faculties. Professors must both teach students and also produce original research in their own field. The quality of this research is assessed by academic publications. At the same time, universities have another responsibility to equip their students for the real world, however that is defined. Most students learning from professors will not go into academics themselves—so how do academics best prepare them for their future careers, whatever that may be? Whether academic research actually produces anything that is useful to the practice of business, or even whether it is its job to do so, are questions that can provoke vigorous arguments on campus.

The debate, which first flared during the 1950s, was reignited in August, when AACSB Interna­tional. the most widely recognised global accrediting agency for business schools, announced it would consider changing the way it evaluates research. The news followed rather damning criti­cism in 2002 from Jeffrey Pfefler. a Stanford professor, and Christina Fong of Washington Uni­versity, which questioned whether business education in its current guise was sustainable. The study found that traditional modes of academia were not adequately preparing students for the kind of careers they faced in current times. The most controversial recommendation in AACSB’s draft report (which was sent round to administrators for their comment) is that the schools should be required to demonstrate the value of their faculties’ research not simply by listing its citations in journals, but by demonstrating the impact it has in the professional world. New qualifiers, such as average incomes, student placement in top firms and business collaborations would now be considered just as important as academic publications.

AACSB justifies its stance by saying that it wants schools and faculty to play to their strengths, whether they be in pedagogy, in the research of practical applications, or in scholarly endeavor. Traditionally, universities operate in a pyramid structure. Everyone enters and stays in an attempt to be successful in their academic field. A psychology professor must publish competi­tive research in the top neuroscience journals. A Cultural Studies professor must send graduate students on new field research expeditions to be taken seriously. This research is the core of a university’s output. And research of any kind is expensive—AACSB points out that business schools in America alone spend more than $320m a year on it. So it seems legitimate to ask for,’what purpose it is undertaken?

If a school chose to specialise in professional outputs rather than academic outputs, it could use such a large sum of money and redirect it into more fruitful programs. For example, if a business school wanted a larger presence of employees at top financial firms, this money may be better spent on a career center which focuses on building the skills of students, rather than paying for more high-level research to be done through the effort of faculty. A change in evaluation could also open the door to inviting more professionals from different fields to teach as adjuncts. Stu­dents could take accredited courses from people who are currently working in their dream field. The AACSB insists that universities answer the question as to why research is the most critical component of traditional education.

On one level, the question is simple to answer. Research in business schools, as anywhere else, is about expanding the boundaries of knowledge; it thrives on answering unasked questions. Surely this pursuit of knowledge is still important to the university system. Our society progresses because we learn how to do things in new ways, a process which depends heavily on research and academics. But one cannot ignore the other obvious practical uses of research publications. Research is also about cementing schools’ and professors’ reputations. Schools gain kudos from their faculties’ record of publication: which journals publish them, and how often. In some cases, such as with government-funded schools in Britain, it can affect how much money they receive. For professors, the mantra is often “publish or perish”. Their careers depend on being seen in the right journals.

But at a certain point, one has to wonder whether this research is being done for the benefit of the university or for the students the university aims to teach. Greater publications will attract greater funding, which will in turn be spent on better publications. Students seeking to enter pro­fessions out of academia find this cycle frustrating, and often see their professors as being part of the “Ivory Tower” of academia, operating in a self-contained community that has little influ­ence on the outside world.

The research is almost universally unread by real-world managers. Part of the trouble is that the journals labour under a similar ethos. They publish more than 20,000 articles each year. Most of the research is highly quantitative, hypothesis-driven and esoteric. As a result, it is almost univer­sally unread by real-world managers. Much of the research criticises other published research. A paper in a 2006 issue of Strategy & Leadership commented that “research is not designed with managers’ needs in mind, nor is it communicated in the journals they read. For the most part, it has become a self-referential closed system irrelevant to corporate performance.” The AACSB demands that this segregation must change for the future of higher education. If students must invest thousands of dollars for an education as part of their career path, the academics which serve the students should be more fully incorporated into the professional world. This means that uni­versities must focus on other strengths outside of research, such as professional networks, tech­nology skills, and connections with top business firms around the world. Though many universi­ties resisted the report, today’s world continues to change. The universities which prepare students for our changing future have little choice but to change with new trends and new standards.

What the Managers Really Do?

When students graduate and first enter the workforce, the most common choice is to find an entry-level position. This can be a job such as an unpaid internship, an assistant, a secretary, or a junior partner position. Traditionally, we start with simpler jobs and work our way up. Young professionals start out with a plan to become senior partners, associates, or even managers of a workplace. However, these promotions can be few and far between, leaving many young professionals unfamiliar with management experience. An important step is understanding the role and responsibilities of a person in a managing position. Managers are organisational members who are responsible for the work performance of other organisational members. Managers have formal authority to use organisational resources and to make decisions. Managers at different levels of the organisation engage in different amounts of time on the four managerial functions of planning, organising, leading, and controlling.

However, as many professionals already know, managing styles can be very different depending on where you work. Some managing styles are strictly hierarchical. Other managing styles can be more casual and relaxed, where the manager may act more like a team member rather than a strict boss. Many researchers have created a more scientific approach in studying these different approaches to managing. In the 1960s, researcher Henry Mintzberg created a seminal organisational model using three categories. These categories represent three major functional approaches, which are designated as interpersonal, informational and decisional.

Introduced Category 1: INTERPERSONAL ROLES. Interpersonal roles require managers to direct and supervise employees and the organisation. The figurehead is typically a top of middle manager. This manager may communicate future organisational goals or ethical guidelines to employees at company meetings. They also attend ribbon-cutting ceremonies, host receptions, presentations and other activities associated with the figurehead role. A leader acts as an example for other employees to follow, gives commands and directions to subordinates, makes decisions, and mobilises employee support. They are also responsible for the selection and training of employees. Managers must be leaders at all levels of the organisation; often lower-level managers look to top management for this leadership example. In the role of liaison, a manager must coordinate the work of others in different work units, establish alliances between others, and work to share resources. This role is particularly critical for middle managers, who must often compete with other managers for important resources, yet must maintain successful working relationships with them for long time periods.

Introduced Category 2: INFORMATIONAL ROLES. Informational roles are those in which managers obtain and transmit information. These roles have changed dramatically as technology has improved. The monitor evaluates the performance of others and takes corrective action to improve

that performance. Monitors also watch for changes in the environment and within the company that may affect individual and organisational performance. Monitoring occurs at all levels of management. The role of disseminator requires that managers inform employees of changes that affect them and the organisation. They also communicate the company’s vision and purpose.

Introduced Category 3: DECISIONAL ROLES. Decisional roles require managers to plan strategy and utilise resources. There are four specific roles that are decisional. The entrepreneur role requires the manager to assign resources to develop innovative goods and services, or to expand a business. The disturbance handler corrects unanticipated problems facing the organisation from the internal or external environment. The third decisional role, that of resource allocator, involves determining which work units will get which resources. Top managers are likely to make large, overall budget decisions, while middle managers may make more specific allocations. Finally, the negotiator works with others, such as suppliers, distributors, or labor unions, to reach agreements regarding products and services.

Although Mintzberg’s initial research in 1960s helped categorise manager approaches, Mintzberg was still concerned about research involving other roles in the workplace. Minstzberg considered expanding his research to other roles, such as the role of disseminator, figurehead, liaison and spokesperson. Each role would have different special characteristics, and a new categorisation system would have to be made for each role to understand it properly.

While Mintzberg’s initial research was helpful in starting the conversation, there has since been criticism of his methods from other researchers. Some criticisms of the work were that even though there were multiple categories, the role of manager is still more complex. There are still many manager roles that are not as traditional and are not captured in Mintzberg’s original three categories. In addition, sometimes, Mintzberg’s research was not always effective. The research, when applied to real-life situations, did not always improve the management process in real-life practice.

These two criticisms against Mintzberg’s research method raised some questions about whether or not the research was useful to how we understand “managers” in today’s world. However, even if the criticisms against Mintzberg’s work are true, it does not mean that the original research from the 1960s is completely useless. Those researchers did not say Mintzberg’s research is invalid. His research has two positive functions to the further research.

The first positive function is Mintzberg provided a useful functional approach to analyse management. And he used this approach to provide a clear concept of the role of manager to the researcher. When researching human behavior, it is important to be concise about the subject of the research. Mintzberg’s research has helped other researchers clearly define what a “manager” is, because in real-life situations, the “manager” is not always the same position title. Mintzberg’s definitions added clarity and precision to future research on the topic.

The second positive function is Mintzberg’s research could be regarded as a good beginning to give a new insight to further research on this field in the future. Scientific research is always a gradual process. Just because Mintzberg’s initial research had certain flaws, does not mean it is useless to other researchers. Researchers who are interested in studying the workplace in a systematic way have older research to look back on. A researcher doesn’t have to start from the very beginning— older research like Mintzberg’s have shown what methods work well and what methods are not as appropriate for workplace dynamics. As more young professionals enter the job market, this research will continue to study and change the way we think about the modern workplace.

How Well Do We Concentrate?

A Do you read while listening to music? Do you like to watch TV while finishing your homework? People who have these kinds of habits are called multi-taskers. Multitaskers are able to complete two tasks at the same time by dividing their focus. However, Thomas Lehman, a researcher in Psychology, believes people never really do multiple things simultaneously. Maybe a person is reading while listening to music, but in reality, the brain can only focus on one task. Reading the words in a book will cause you to ignore some of the words of the music. When people think they are accomplishing two different tasks efficiently, what they are really doing is dividing their focus. While listening to music, people become less able to focus on their surroundings. For example, we all have experience of times when we talk with friends and they are not responding properly. Maybe they are listening to someone else talk, or maybe they are reading a text on their smart phone and don’t hear what you are saying. Lehman called this phenomenon “email voice”

B the world has been changed by computers and its spin offs like smart-phones or cellphones. Now that most individuals have a personal device, like a smart-phone or a laptop, they are frequently reading, watching or listening to virtual information. This raises the occurrence of multitasking in our day to day life. Now when you work, you work with your typewriter, your cellphone, and some colleagues who may drop by at any time to speak with you. In professional meetings, when one normally focuses and listens to one another, people are more likely to have a cell phone in their lap, reading or communicating silently with more people than ever, liven inventions such as the cordless phone has increased multitasking. In the old days, a traditional wall phone would ring, and then the housewife would have to stop her activities to answer it. When it rang, the housewife will sit down with her legs up. and chat, with no laundry or sweeping or answering the door. In the modern era, our technology is convenient enough to not interrupt our daily tasks.

C Earl Miller, an expert at the Massachusetts Institute of Technology, studied the prefrontal cortex, which controls the brain while a person is multitasking. According to his studies, the size of this cortex varies between species, He found that for humans, the size of this part constitutes one third of the brain, while it is only 4 to 5 percent in dogs, and about 15% in monkeys. Given that this cortex is larger on a human, it allows a human to be more flexible and accurate in his or her multitasking.. However, Miller wanted to look further into whether the cortex was truly processing information about two different tasks simultaneously. He designed an experiment where he presents visual stimulants to his subjects in a wax that mimics multi-tasking. Miller then attached sensors to the patients ” heads to pick up the electric patterns of the brain. This sensor would show if ” the brain particles, called neurons, were truly processing two different tasks. What he found is that the brain neurons only lit up in singular areas one at a time, and never simultaneously.

D Davis Meyer, a professor of University of Michigan, studied the young adults in a similar experiment. He instructed them to simultaneously do math problems and classify simple words into different categories. For this experiment. Meyer found that when you think you are doing several jobs at the same time, you are actually switching between jobs. Even though the people tried to do the tasks at the same time, and both tasks were eventually accomplished, overall, the task look more time than if the person focused on a single task one at a time.

E People sacrifice efficiency when multitasking, Gloria Mark set office workers as his subjects. He found that they were constantly multitasking. He observed that nearly every 11 minutes people at work were disrupted. He found that doing different jobs at the same time may actually save time. However, despite the fact that they are faster, it does not mean they are more efficient. And we are equally likely to self-interrupt as be interrupted by outside sources. He found that in office nearly every 12 minutes an employee would stop and with no reason at all, cheek a website on their computer, call someone or write an email. If they concentrated for more than 20 minutes, they would feel distressed. He suggested that the average person may suffer from a short concentration span. This short attention span might be natural, but others suggest that new technology may be the problem. With cellphones and computers at our sides at all times, people will never run out of distractions. The format of media, such as advertisements, music, news articles and TV shows are also shortening, so people are used to paying attention to information for a very short time.

F So even though focusing on one single task is the most efficient way for our brains to work, it is not practical to use this method in real life. According to human nature, people feel more comfortable and efficient in environments with a variety of tasks, Edward Hallowell said that people are losing a lot of efficiency in the workplace due to multitasking, outside distractions and self-distractions. As a matter of fact, the changes made to the workplace do not have to be dramatic. No one is suggesting we ban e-mail or make employees focus on only one task. However, certain common workplace tasks, such as group meetings, would be more efficient if we banned cell-phones, a common distraction. A person can also apply these tips to prevent self-distraction. Instead of arriving to your office and checking all of your e-mails for new tasks, a common workplace ritual, a person could dedicate an hour to a single task first thing in the morning. Self-timing is a great way to reduce distraction and efficiently finish tasks one by one, instead of slowing ourselves down with multi-tasking.

Improving Patient Safety

Packaging
One of the most prominent design issues in pharmacy is that of drag packaging and patient information leaflets (Pits). Many letters have appeared in The Journal’s letters pages over the years from pharmacists dismayed at the designs of packaging that are “accidents waiting to happen”.

Packaging design in the pharmaceutical industry is handled by either in-house teams or design agencies. Designs for over-the-counter medicines, where characteristics such as attractiveness and distinguish-ability are regarded as significant, are usually commissioned from design agencies. A marketing team will prepare a brief and the designers will come up with perhaps six or seven designs. These are whittled down to two or three that might be tested on a consumer group. In contrast, most designs for prescription-only products are created in-house. In some cases, this may simply involve applying a company’s house design (ie, logo, colour, font, etc). The chosen design is then handed over to design engineers who work out how the packaging will be produced.

Design considerations
The author of the recently published “Information design for patient safety,” Thea Swayne, tracked the journey of a medicine from manufacturing plant, through distribution warehouses, pharmacies and hospital wards, to patients’ homes. Her book highlights a multitude of design problems with current packaging, such as lookalikes and soundalikes, small type sizes and glare on blister foils. Situations in which medicines are used include a parent giving a cough medicine to a child in the middle of the night and a busy pharmacist selecting one box from hundreds. It is argued that packaging should be designed for moments such as these. “Manufacturers are not aware of the complex situations into which products go. As designers, we are interested in not what is supposed to happen in hospital wards, but what happens in the real world,” Ms Swayne said.

Incidents where vein has been injected intrathecally instead of spine are a classic example of how poor design can contribute to harm. Investigations following these tragedies have attributed some blame to poor typescript.

Safety and compliance
Child protection is another area that gives designers opportunities to improve safety. According to the Child Accident Prevention Trust, seven out of 10 children admitted to hospital with suspected poisoning have swallowed medicines. Although child-resistant closures have reduced the number of incidents, they are not: fully child-proof. The definition of such a closure is one that not more than 15 percent of children aged between 42 and 51 months can open within five minutes. There is scope for improving what is currently available, according to Richard Mawle, a freelance product designer. “Many child-resistant packs are based on strength. They do not necessarily prevent a child from access, but may prevent people with a disability,” he told The Journal. “The legal requirements are there for a good reason, but they are not good enough in terms of the users,” he said. “Older people, especially those with arthritis, may have the same level of strength as a child,” he explained, and suggested that better designs could rely on cognitive skills (eg, making the opening of a container a three-step process) or be based on the physical size of hands.

Mr. Mawle worked with GlaxoSmithKline on a project to improve compliance through design, which involved applying his skills to packaging and PILs. Commenting on the information presented, he said: “There can be an awful lot of junk at the beginning of PILs. For example, why are company details listed towards the beginning of a leaflet when what might be more important for the patient is that the medicine should not be taken with alcohol?”

Design principles and guidelines
Look-alike boxes present a potential for picking errors and an obvious solution would be to use colours to highlight different strengths. However, according to Ms.Swayne, colour differentiation needs to be approached with care. Not only should strong colour contrasts be used, but designating a colour to a particular strength (colour coding) is not recommended because this could lead to the user not reading the text on a box.

Design features can provide the basis for lengthy debates. For example, one argument is that if all packaging is white with black lettering, people would have no choice but to read every box carefully. The problem is that trials of drug packaging design are few—common studies of legibility and comprehensibility concern road traffic signs and visual display units. Although some designers take results from such studies into account, proving that a particular feature is beneficial can be difficult. For example, EU legislation requires that packaging must now include the name of the medicine in Braille but, according to Karel van der Waarde, a design consultant to the pharmaceutical industry, “it is not known how much visually impaired patients will benefit nor how much the reading of visually able patients will be impaired”.

More evidence might, however, soon be available. EU legislation requires PILs to reflect consultations with target patient groups to ensure they are legible, clear and easy to use. This implies that industry will have to start conducting tests. Dr. van der Waarde has performed readability studies on boxes and PILs for industry. A typical study involves showing a leaflet or package to a small group and asking them questions to test understanding. Results and comments are used to modify the material, which is then tested on a larger group. A third group is used to show that any further changes made are an improvement. Dr. van der Waarde is, however, sceptical about the legal requirements and says that many regulatory authorities do not have the resources to handle packaging information properly. “They do not look at the use of packaging in a practical context—they only see one box at a time and not several together as pharmacists would do,” he said.

Innovations
The RCA innovation exhibition this year revealed designs for a number of innovative objects. “The popper”, by Hugo Glover, aims to help arthritis sufferers remove tablets from blister packs, and “pluspoint”, by James Cobb, is an adrenaline auto-injector that aims to overcome the fact that many patients do not carry their auto-injectors due to their prohibitive size. The aim of good design, according Roger Coleman, professor of inclusive design at the RCA, is to try to make things more user-friendly as well as safer. Surely, in a patient-centred health system, that can only be a good thing. “Information design for patient safety” is not intended to be mandatory. Rather, its purpose is to create a basic design standard and to stimulate innovation. The challenge for the pharmaceutical industry, as a whole, is to adopt such a standard.

GOING NOWHERE FAST

THIS is ludicrous! ‘We can talk to people anywhere in the world or fly to meet them in a few hours. e can even send probes to other planets. But when it comes to getting around our cities, we depend on systems that have scarcely changed since the days of Gottlieb Daimler.

In recent years, the pollution belched out by millions of vehicles has dominated the debate about transport. The problem has even persuaded California – that home of car culture – to curb traffic growth. But no matter how green they become, cars are unlikely to get us around crowded cities any faster. And persuading people to use trains and buses w ill always be an uphill struggle. Cars, after all, are popular for very good reasons, as anyone with small children or heavy shopping knows.

So politicians should be trying to lure people out of their cars, not forcing them out. There’s certainly no shortage of alternatives. Perhaps the most attractive is the concept known as personal rapid transit (PRT), independently invented in the US and Europe in the 1950s.

The idea is to go to one of many stations and hop into a computer-controlled car, which can whisk you to your destination along a network of guideways. You wouldn’t have to share your space with strangers, and with no traffic lights, pedestrians or parked cars to slow things down, PRT guideways can carry far more traffic, non stop, than any inner city road.

It’s a wonderful vision, but the odds are stacked against PRT for a number of reasons. The first cars ran on existing roads, and it was only after they became popular — and after governments started earning revenue from them-that a road network designed specifically for motor vehicles was built. With PRT, the infrastructure would have to come first-and that would cost megabucks. What’s more, any transport system that threatened the car’s dominance would be up against all those with a stake in maintaining the status quo, from private car owners to manufacturers and oil multinationals. Even if PRTs were spectacularly successful in trials, it might not make much difference. Superior technology doesn’t always triumph, as the VHS versus Betamax and Windows versus Apple Mac battles showed.

But “dual-mode” systems might just succeed where PRT seems doomed to fail. The Danish RUF system envisaged by Palle Jensen, for example, resembles PRT but with one key difference: vehicles have wheels as well as a slot allowing them to travel on a monorail, so they can drive off the rail onto a normal road. Once on a road, the occupant would take over from the computer, and the RUF vehicle – the term comes from a Danish saying meaning to “go fast” – would become an electric car.

Build a fast network of guideways in a busy city centre and people would have a strong incentive not just to use public RUF vehicles, but also to buy their own dual-mode vehicle. Commuters could drive onto the guideway, sit back and read as they are chauffeured into the city. At work, they would jump out, leaving their vehicles to park themselves. Unlike PRT, such a system could grow organically, as each network would serve a large area around it and people nearby could buy into it. And a dual-mode system might even win the support of car manufacturers, who could easily switch to producing dual-mode vehicles.

Of course, creating a new transport system will not be cheap or easy. But unlike adding a dedicated bus lane here or extending the underground railway there, an innovative system such as Jensen’s could transform cities.

And it’s not just a matter of saving a few minutes a day. According to the Red Cross, more than 30 million people have died in road accidents in the past century-three times the number killed in the First World War-and the annual death toll is rising. And what’s more, the Red Cross believes road accidents will become the third biggest cause of death and disability by 2020, ahead of diseases such as AIDS and tuberculosis. Surely we can find a better way to get around?

They travel the four comers of the globe, scouring jungles, forests and savannas. But they’re not looking for ancient artefacts, lost treasure or undiscovered tombs. Just pods. It may lack the romantic allure of archaeology, or the whiff of danger that accompanies going after big game, but seed hunting is an increasingly serious business. Some seek seeds for profit—hunters in the employ of biotechnology firms, pharmaceutical companies and private corporations on the lookout for species that will yield the drugs or crops of the future. Others collect to conserve, working to halt the sad slide into extinction facing so many plant species.

B Among the pioneers of this botanical treasure hunt was John Tradescant, an English royal gardener who brought back plants and seeds from his journeys abroad in the early 1600s. Later, the English botanist Sir Joseph Banks-who was the first director of the Royal Botanic Gardens at Kew and travelled with Captain James Cook on his voyages near the end of the 18th century—was so driven to expand his collections that he sent botanists around the world at his own expense.

C Those heady days of exploration and discovery may be over, but they have been replaced by a pressing need to preserve our natural history for the future. This modem mission drives hunters such as Dr Michiel van Slageren, a good-natured Dutchman who often sports a wide-brimmed hat in the field—he could easily be mistaken for the cinematic hero Indiana Jones. He and three other seed hunters work at the Millennium Seed Bank, an 80 million [pounds sterling] international conservation project that aims to protect the world’s most endangered wild plant species

D The group’s headquarters are in a modem glass-and-concrete structure on a 200-hectare Estate at Wakehurst Place in the West Sussex countryside. Within its underground vaults are 260 million dried seeds from 122 countries, all stored at -20 Celsius to survive for centuries. Among the 5，100 species represented are virtually all of Britain’s 1,400 native seed-bearing plants, the most complete such collection of any country’s flora.

E Overseen by the Royal botanic gardens, the Millennium Seed Bank is the world’s largest wild-plant depository. It aims to collect 24,000 species by 2010. The reason is simple: thanks to humanity’s efforts, an estimated 25 per cent of the world’s plants are on the verge of extinction and may vanish within 50 years. We’re currently responsible for habitat destruction on an unprecedented scale, and during the past 400 years, plant species extinction rates have been about 70 times greater than those indicated by the geological record as being ’normal’. Experts predict that during the next 50 years a further one billion hectares of wilderness will be converted to farmland in developing countries alone.

F The implications of this loss are enormous. Besides providing staple food crops, plants are a source of many machines and the principal supply of fuel and building materials in many parts of the world. They also protect soil and help regulate the climate. Yet, across the globe, plant species are being driven to extinction before their potential benefits are discovered.

G The world Conservation Union has listed 5,714 threatened species is sure to be much higher. In the UK alone, 300 wild plant species are classified as endangered. The Millennium Seed Bank aims to ensure that even if a plant becomes extinct in the wild，it won’t be lost forever. Stored seeds can be used the help restore damaged or destroyed environment or in scientific research to find new benefits for society- in medicine, agriculture or local industry- that would otherwise be lost.

H Seed banks are an insurance policy to protect the world’s plant heritage for the future, explains Dr Paul Smith, another Kew seed hunter. “Seed conservation techniques were originally developed by farmers/’ he says. “Storage is the basis what we do, conserving seeds until you can use them-just as in farming.” Smith says there’s no reason why any plant species should become extinct, given today’s technology. But he admits that the biggest challenge is finding, naming and _ categorising all the world’s plants. And someone has to gather these seeds before it’s too late. “There aren’t a lot of people out there doing this,” he says” The key is to know the flora from a particular area, and that knowledge takes years to acquire.”

I There are about 1,470 seed banks scattered around the globe, with a combined total of 5.4 million samples, of which perhaps two million are distinct non-duplicates. Most preserve genetic material for agriculture use in order to ensure crop diversity; others aim to conserve wild species, although only 15 per cent of all banked plants are wild.

J Imperial College, London, examined crop collections from 151 countries and found that while the number of plant samples had increased in two thirds of the countries, budget had been cut in a quarter and remained static in another 35 per cent. Th UN’s Food and Agriculture Organization and the Consultative Group on International Agricultural Research has since set up the Global Conservation Trust, which aims to raise US $260 million to protect seed banks in perpetuity.

Assessing the Risk

As a title for a supposedly unprejudiced debate on scientific progress, “Panic attack: interrogating our obsession with risk” did not bode well. Held last week at the Royal Institution in London, the event brought together scientists from across the world to ask why society is so obsessed with risk and to call for a “more rational” approach. “We seem to be organising society around the grandmotherly maxim of ‘better safe than sorry’,” exclaimed Spiked, the online publication that organised the event. “What are the consequences of this overbearing concern with risks?”

The debate was preceded by a survey of 40 scientists who were invited to describe how awful our lives would be if the “precautionary principle” had been allowed to prevail in the past. Their response was: no heart surgery or antibiotics, and hardly any drugs at all; no aeroplanes, bicycles or high-voltage power grids; no pasteurisation, pesticides or bio-technology; no quantum mechanics; no wheel; no “discovery” of America. In short, their message was: no risk, no gain.

They have absolutely missed the point. The precautionary principle is a subtle idea. It has various forms, but all of them generally include some notion of cost- effectiveness. Thus the point is not simply to ban things that are not known to be absolutely safe. Rather, it says: “Of course you can make no progress without risk. But if there is no obvious gain from taking the risk, then don’t take it.”

Clearly, all the technologies listed by the 40 well-chosen savants were innately risky at their inception, as all technologies are. But all of them would have received the green light under the precautionary principle because they all had the potential to offer tremendous benefits — the solutions to very big problems — if only the snags could be overcome.

If the precautionary principle had been in place, the scientists tell us, we would not have antibiotics. But of course we would — if the version of the principle that sensible people now understand had been applied. When penicillin was discovered in the 1920s, infective bacteria were laying waste to the world. Children died from diphtheria and whooping cough, every open drain brought the threat of typhoid, and any wound could lead to septicaemia and even gangrene.

Penicillin was turned into a practical drug during the Second World War, when the many pestilences that result from war threatened to kill more people than the bombs. Of course antibiotics were a priority. Of course the risks, such as they could be perceived, were worth taking.

And so with the other items on the scientists’ list: electric light bulbs, blood transfusions, CAT scans, knives, the measles vaccine — the precautionary principle would have prevented all of them, they tell us. But this is just plain wrong. If the precautionary principle had been applied properly, all these creations would have passed muster, because all offered incomparable advantages compared to the risks perceived at the time.

Section 2
Another issue is at stake here. Statistics are not the only concept people use when weighing up risk. Human beings, subtle and evolved creatures that we are, do not survive to threescore years and ten simply by thinking like pocket calculators. A crucial issue is consumer’s choice. In deciding whether to pursue the development of a new technology, the consumer’s right to choose should be considered alongside considerations of risk and benefit. Clearly, skiing is more dangerous than genetically modified tomatoes. But people who ski choose to do so; they do not have skiing thrust upon them by portentous experts of the kind who now feel they have the right to reconstruct our crops. Even with skiing, there is the matter of cost effectiveness to consider: skiing, I am told, is exhilarating. Where is the exhilaration in GM soya?

Indeed, in contrast to all the other items on Spiked’s list, GM crops stand out as an example of a technology whose benefits are far from clear. Some of the risks can at least be defined. But in the present economic climate, the benefits that might accrue from them seem dubious. Promoters of GM crops believe that the future population of the world cannot be fed without them. That is untrue. The crops that really matter are wheat and rice, and there is no GM research in the pipeline that will seriously affect the yield of either. GM is used to make production cheaper and hence more profitable, which is an extremely questionable ambition.

The precautionary principle provides the world with a very important safeguard. If it had been in place in the past, it might, for example, have prevented insouciant miners from polluting major rivers with mercury. We have come to a sorry pass when scientists, who should above all be dispassionate scholars, feel they should misrepresent such a principle for the purposes of commercial and political propaganda. People at large continue to mistrust science and the high technologies it produces, partly because they doubt the wisdom of scientists. On such evidence as this, these doubts are fully justified.

The Origins Of Laughter

While joking and wit are uniquely human inventions, laughter certainly is not. Other creatures, including chimpanzees, gorillas and even rats, laugh. The fact that they laugh suggests that laughter has been around for a lot longer than we have.

There is no doubt that laughing typically involves groups of people. “Laughter evolved as a signal to others — it almost disappears when we are alone,” says Robert Provine, a neuroscientist at the University of Maryland. Provine found that most laughter comes as a polite reaction to everyday remarks such as “see you later”, rather than anything particularly funny. And the way we laugh depends on the company we’re keeping. Men tend to laugh longer and harder when they are with other men, perhaps as a way of bonding. Women tend to laugh more and at a higher pitch when men are present, possibly indicating flirtation or even submission.

To find the origins of laughter, Provine believes we need to look at play. He points out that the masters of laughing are children, and nowhere is their talent more obvious than in the boisterous antics, and the original context is play. Well-known primate watchers, including Dian Fossey and Jane Goodall, have long argued that chimps laugh while at play. The sound they produce is known as a pant laugh. It seems obvious when you watch their behavior — they even have the same ticklish spots as we do. But after removing the context, the parallel between human laughter and a chimp’s characteristic pant laugh is not so clear. When Provine played a tape of the pant laughs to 119 of his students, for example, only two guessed correctly what it was.

These findings underline how chimp and human laughter vary- When we laugh the sound is usually produced by chopping up a single exhalation into a series of shorter with one sound produced on each inward and outward breath. The question is: does this pant laughter have the same source as our own laughter? New research lends weight to the idea that it does. The findings come from Elke Zimmerman, head of the Institute for Zoology in Germany, who compared the sounds made by babies and chimpanzees in response to tickling during the first year of; their life. Using sound spectrographs to reveal the pitch and intensity of vocalizations, she discovered that chimp and human baby laughter follow broadly the same pattern. Zimmerman believes the closeness of baby laughter to chimp laughter supports the idea that laughter was around long before humans arrived on the scene. What started simply as a modification of breathing associated with enjoyable and playful interactions has acquired a symbolic meaning as an indicator of pleasure.

Pinpointing when laughter developed is another matter. Humans and chimps share a common ancestor that lived perhaps 8 million years ago, but animals might have been laughing long before that. More distantly related primates, including gorillas, laugh, and anecdotal evidence suggests that other social mammals can do too. Scientists are currently testing such stories with a comparative analysis of just how common laughter is among animals. So far, though, the most compelling evidence for laughter beyond primates comes from research done by Jaak Panksepp from Bowling Green State University, Ohio, into the ultrasonic chirps produced by rats during play and in response to tickling.

All this still doesn’t answer the question of why we laugh at all. One idea is that laughter and tickling originated as a way of sealing the relationship between mother and child. Another is that the reflex response to tickling is protective, alerting us to the presence of crawling creatures that might harm us or compelling us to defend the parts of our bodies that are most vulnerable in hand-to-hand combat. But the idea that has gained the most popularity in recent years is that laughter in response to tickling is a way for two individuals to signal and test their trust in one another. This hypothesis starts from the observation that although a little tickle can be enjoyable, if it goes on too long it can be torture. By engaging in a bout of tickling, we put ourselves at the mercy of another individual, and laughing is what makes it a reliable signal of trust, according to Tom Flamson, a laughter researcher at the University of California, Los Angels. “Even in rats, laughter, tickle, play and trust are linked. Rats chirp a lot when they play,” says Flamson. “These chirps can be aroused by tickling. And they get bonded to us as a result, which certainly seems like a show of trust.”

We’ll never know which animal laughed the first laugh, or why. But we can be sure it wasn’t in response to a prehistoric joke. The funny thing is that while the origins of laughter are probably quite serious, we owe human laughter and our language- based humor to the same unique skill. While other animals pant, we alone can control our breath well enough to produce the sound of laughter. Without that control there would also be no speech — and no jokes to endure.

The Lost City

Thanks to modern remote-sensing techniques, a ruined city in Turkey is slowly revealing itself as one of the greatest and most mysterious cities of the ancient world. Sally Palmer uncovers more.

A The low granite mountain, known as Kerkenes Dag, juts from the northern edge of the Cappadocian plain in Turkey. Sprawled over the mountainside are the ruins of an enormous city, contained by crumbling defensive walls seven kilometers long. Many respected archaeologists believe these are the remains of the fabled city of Pteria, the sixth-century BC stronghold of the Medes that the Greek historian Herodotus described in his famous work The Histories. The short-lived city came under Median control and only fifty years later was sacked, burned and its strong stone walls destroyed.

B British archaeologist Dr Geoffrey Summers has spent ten years studying the site. Excavating the ruins is a challenge because of the vast area they cover. The 7 km perimeter walls run around a site covering 271 hectares. Dr Summers quickly realised it would take far too long to excavate the site using traditional techniques alone. So he decided to use modern technology as well to map the entire site, both above and beneath the surface, to locate the most interesting areas and priorities to start digging.

C In 1993, Dr Summers hired a special hand-held balloon with a remote-controlled camera attached. He walked over the entire site holding the balloon and taking photos. Then one afternoon, he rented a hot-air balloon and floated over the site, taking yet more pictures. By the end of the 1994 season, Dr Summers and his team had a jigsaw of aerial photographs of the whole site. The next stage was to use remote sensing, which would let them work out what lay below the intriguing outlines and ruined walls. “Archaeology is a discipline that lends itself very well to remote sensing because it revolves around space,” says Scott Branting, an associated director of the project. He started working with Dr Summers in 1995.

D The project used two main remote-sensing techniques. The first is magnetometry, which works on the principle that magnetic fields at the surface of the Earth are influenced by what is buried beneath. It measures localised variations in the direction and intensity of this magnetic field. “The Earth s magnetic field can vary from place to place, depending on what happened there in the past says Brantmg. “If something containing iron oxide was heavily burnt, by natural or human actions, the iron particles in it can be permanently reoriented, like a compass needle, to align with the Earth’s magnetic field present at that point in time and space.” The magnetometer detects differences in the orientations and intensities of these iron particles from the present-day magnetic field and uses them to produce an image of what lies below ground.

E Kerkenes Dag lends itself particularly well to magnetometry because it was all burnt once in a savage fire. In places the heat was sufficient to turn sandstone to glass and to melt granite. The fire was so hot that there were strong magnetic signatures set to the Earth’s magnetic field from the time – around 547 BC – resulting in extremely clear pictures. Furthermore, the city was never rebuilt. “If you have multiple layers, it can confuse pictures, because you have different walls from different periods giving signatures that all go in different directions,” says Branting. “We only have one going down about 1.5 meters, so we can get a good picture of this fairly short-lived city.”

F The other main sub-surface mapping technique, which is still being used at the site, is resistivity. This technique measures the way electrical pulses are conducted through sub¬surface soil. It’s done by shooting pulses into the ground through a thin metal probe. Different materials have different electrical conductivity. For example, stone and mudbrick are poor conductors, but looser, damp soil conducts very well. By walking around the site and taking about four readings per metre, it is possible to get a detailed idea of what is where beneath the surface. The teams then build up pictures of walls, hearths and other remains. “It helps a lot if it has rained, because the electrical pulse can get through more easily,” says Branting. “Then if something is more resistant, it really shows up.” This is one of the reasons that the project has a spring season, when most of the resistivity work is done. Unfortunately, testing resistivity is a lot slower than magnetometry. “If we did resistivity over the whole site it would take about 100 years,” says Branting. Consequently, the team is concentrating on areas where they want to clarify pictures from the magnetometry.

G Remote sensing does not reveal everything about Kerkenes Dag, but it shows the most interesting sub-surface areas of the site. The archaeologists can then excavate these using traditional techniques. One surprise came when they dug out one of the gates in the defensive walls. “Our observations in early seasons led us to assume that we were looking at a stone base from a mudbrick city wall, such as would be found at most other cities in the Ancient Near East,” says Dr Summers. “When we started to excavate we were staggered to discover that the walls were made entirely from stone and that the gate would have stood at least ten metres high. After ten years of study, Pteria is gradually giving up its secrets.”

Designed to Last

Jonathan Chapman, a senior lecturer at the University of Brighton, UK, is one of a new breed of ‘sustainable designers’. Like many of us, they are concerned about the huge waste associated with Western consumer culture and the damage this does to the environment. Some, like Chapman, aim to create objects we will want to keep rather than discard. Others are working to create more efficient or durable consumer goods, or goods designed with recycling in mind. The waste entailed in our fleeting relationships with consumer durables is colossal.

Domestic power tools, such as electric drills, are a typical example of such waste. However much DIY the purchaser plans to do, the truth is that these things are thrown away having been used, on average, for just ten minutes. Most will serve ‘conscience time’, gathering dust on a shelf in the garage; people are reluctant to admit that they have wasted their money. However, the end is inevitable: thousands of years in land-fill waste sites. In its design, manufacture, packaging, transportation and disposal, a power tool consumes many times its own weight of resources, all for a shorter active lifespan than that of the average small insect.

To understand why we have become so wasteful, we should look to the underlying motivation of consumers. “People own things to give expression to who they are, and to show what group of people they feel they belong to,” Chapman says. In a world of mass production, however, that symbolism has lost much of its potency. For most of human history, people had an intimate relationship with objects they used or treasured. Often they made the objects themselves, or family members passed them on. For more specialised objects, people relied on expert manufacturers living close by, whom they probably knew personally. Chapman points out that all these factors gave objects a history — a narrative — and an emotional connection that today’s mass-produced goods cannot possibly match. Without these personal connections, consumerist culture idolizes novelty instead. People know that they cannot buy happiness, but the chance to remake themselves with glossy, box-fresh products seems irresistible. When the novelty fades, they simply renew the excitement by buying more.

Chapman’s solution is what he calls ’emotionally durable design’. He says the challenge for designers is to create things we want to keep. This may sound like a tall order but it can be surprisingly straightforward. A favorite pair of old jeans, for example, just do not have the right feel until they have been worn and washed a hundred times. It is as if they are sharing the wearer’s life story. The look can be faked, but it is simply not the same. Walter Stahel, visiting professor at the University of Surrey, UK, calls this ‘the teddy bear factor’. No matter how ragged and worn a favorite teddy becomes, we don’t rush out and buy another one. As adults, our teddy bear connects us to our childhood and this protects it from obsolescence. Stahel argues that this is what sustainable design needs to do with more products.

The information age was supposed to lighten our economies and reduce our impact on the environment, but, in fact, the reverse seems to be happening. We have simply added information technology to the industrial era and speeded up the developed world’s metabolism. The cure is hardly rocket science: minimise waste, stop moving things around so much and use people more. So what will post-throwaway consumerism look like? It might be as simple as installing energy-saving light bulbs, more efficient washing machines or choosing locally produced groceries with less packaging. In general, we will spend less on goods and more on services. Instead of buying a second car, for example, we might buy into a car-sharing network. Rather than following our current wasteful practices, we will buy less and rent a lot more; why own things such as tools that you use infrequently, especially things are likely to be updated all the time?

Consumer durables will increasingly be sold with plans for their disposal. Electronic goods such as mobile phones will be designed to be recyclable, with the extra cost added into the retail price. Following Chapman’s notion of emotionally durable design, there will be a move away from mass production and towards tailor-made articles and products designed and manufactured with greater craftsmanship, products which will be repaired rather than replaced, in the same way as was done in our grandparents’ time. Companies will replace profit from bulk sales by servicing and repairing products chosen because we want them to last.

Chapman acknowledges that it will be a challenge to persuade people to buy fewer goods, and ones that they intend to keep. At the moment, price competition between retailers makes it cheaper for consumers to replace rather than repair.

Products designed to be durable and emotionally satisfying are likely to be more expensive, so how will we be persuaded to choose sustainability? Tim Cooper, from Sheffield Hallam University in the UK, points out that many people are already happy to pay a premium for quality, and that they also tend to value and care more for expensive goods. Chapman is also positive: “People are ready to keep things for longer,” he says, “The problem is that a lot of industries don’t know how to do that.” Chapman believes that sustainable design is here to stay. “The days when large corporations were in a position to choose whether to jump on the sustainability band-wagon or not are coming to an end,” he says. Whether this is also the beginning of the end of the throwaway society remains to be seen.

Man or Machine

A During July 2003, the Museum of Science in Cambridge, Massachusetts exhibited what Honda calls ‘the world’s most advanced humanoid robot’, ASIMO (the Advanced Step in Innovative Mobility). Honda’s brainchild is on tour in North America and delighting audiences wherever it goes. After 17 years in the making, ASIMO stands at four feet tall, weighs around 115 pounds and bob like a child in an astronaut’s suit. Though it is difficult to see ASIMO’s face at a distance, on closer inspection it has a smile and two large ‘eyes’ that conceal cameras. The robot cannot work autonomously — its actions are ‘remote controlled’ by scientists through the computer in its backpack. Yet watching ASMIO perform at a show in Massachusetts it seemed uncannily human. The audience cheered as ASIMO walked forwards and backwards, side to side and up and downstairs. It can even dance to the Hawaiian Hula.

B While the Japanese have made huge strides in solving some of the engineering problems of human kinetics and bipedal movements, for the past 10 years scientists at MIT’s former Artificial Intelligence (Al) lab (recently renamed the Computer Science and Artificial Intelligence Laboratory, CSAIL) have been making robots that can behave like humans and interact with humans. One of MIT’s robots, Kismet, is an anthropomorphic head and has two eyes (complete with eyelids), ears, a mouth, and eyebrows. It has several facial expressions, including happy, sad, frightened and disgusted. Human interlocutors are able to read some of the robot’s facial expressions, and often change their behaviour towards the machine as a result – for example, playing with it when it appears ‘sad’. Kismet is now in MIT’s museum, but the ideas developed here continue to be explored in new robots.

C Cog (short for Cognition) is another pioneering project from MIT’s former Al lab. Cog has a head, eyes, two arms, hands and a torso — and its proportions were originally measured from the body of a researcher in the lab. The work on Cog has been used to test theories of embodiment and developmental robotics, particularly getting a robot to develop intelligence by responding to its environment via sensors, and to learn through these types of interactions. This approach to Al was thought up and developed by a team of students and researchers led by the head of MIT’s former Al lab, Rodney Brooks (now head of CSAIL), and represented a completely new development.

D This work at MIT is getting furthest down the road to creating human-like and interactive robots. Some scientists argue that ASIMO is a great engineering feat but not an intelligent machine — because it is unable to interact autonomously with unpredictabilities in its environment in meaningful ways, and learn from experience. Robots like Cog and Kismet and new robots at MIT’s CSAIL and media lab, however, are beginning to do this.

E These are exciting developments. Creating a machine that can walk, make gestures and learn from its environment is an amazing achievement. And watch this space: these achievements are likely rapidly to be improved upon. Humanoid robots could have a plethora of uses in society, helping to free people from everyday tasks. In Japan, for example, there is an aim to create robots that can do the tasks similar to an average human, and also act in more sophisticated situations as firefighters, astronauts or medical assistants to the elderly in the workplace and in homes — partly in order to counterbalance the effects of an ageing population.

F So in addition to these potentially creative plans there lies a certain dehumanisation. The idea that companions can be replaced with machines, for example, suggests a mechanical and degraded notion of human relationships. On one hand, these developments express human creativity — our ability to invent, experiment, and to extend our control over the world. On the other hand, the aim to create a robot like a human being is spurred on by dehumanised ideas — by the sense that human companionship can be substituted by machines; that humans lose their humanity when they interact with technology; or that we are little more than surface and ritual behaviours, that can be simulated with metal and electrical circuits.

G The tension between the dehumanised and creative aspects of robots has long been explored in culture. In Karel Capek’s Rossum’s Universal Robots, a 19 2 1 play in which the term ‘robot’ was first coined, although Capek’s robots had human-like appearance and behaviour, the dramatist never thought these robots were human. For Capek, being human was about much more than appearing to be human. In part, it was about challenging a dehumanising system, and struggling to become recognised and given the dignity of more than a machine. A similar spirit would guide us well through twenty-first century experiments in robotics.

California’s Age of Megafires

There’s a reason fire squads now battling more than a dozen blazes in southern California are having such difficulty containing the flames, despite better preparedness than ever and decades of experience fighting fires fanned by the notorious Santa Ana winds. The wildfires themselves, experts say, generally are hotter, move faster, and spread more erratically than in the past.

Megafires, also called “siege fires,” are the increasingly frequent blazes that burn 500,000 acres or more — 10 times the size of the average forest fire of 20 years ago. One of the current wildfires is the sixth biggest in California ever, in terms of acreage burned, according to state figures and news reports.

The short-term explanation is that the region, which usually has dry summers, has had nine inches less rainfall than normal this year. Longer term, climate change across the West is leading to hotter days on average and longer fire seasons. The trend to more superhot fires, experts say, has been driven by a century-long policy of the US Forest Service to stop wildfires as quickly as possible. The unintentional consequence was to halt the natural eradication of underbrush, now the primary fuel for megafires.

Three other factors contribute to the trend, they add. First is climate change marked by a 1-degree F rise in average yearly temperature across the West. Second is a fire season that on average is 78 days longer than in the late 1980s. Third is increased building of homes and other structures in wooded areas. “We are increasingly building our homes … in fireprone ecosystems,” says Dominik Kulakowski, adjunct professor of biology at Clark University Graduate School of Geography in Worcester, Mass. Doing that “in many of the forests of the Western US … is like building homes on the side of an active volcano.”

In California, where population growth has averaged more than 600,000 a year for at least a decade, housing has pushed into such areas. “What once was open space is now residential homes providing fuel to make fires burn with greater intensity,” says Terry McHale of the California Department of Forestry firefighters union. “With so much dryness, so many communities to catch fire, so many fronts to fight, it becomes an almost incredible job.”

That said, many experts give California high marks for making progress on preparedness since 2003, when the largest fires in state history scorched 750,000 acres, burned 3,640 homes, and killed 2 2 people. Stung then by criticism of bungling that allowed fires to spread when they might have been contained, personnel are meeting the peculiar challenges of neighborhood and canyon-hopping fires better than in recent years, observers say.

State promises to provide newer engines, planes, and helicopters have been fulfilled. Firefighters unions that then complained of dilapidated equipment, old fire engines, and insufficient blueprints for fire safety are now praising the state’s commitment, noting that funding for firefighting has increased despite huge cuts in many other programs. We are pleased that the Schwarzenegger administration has been very proactive in its support of us and come through with budgetary support of the infrastructure needs we have long sought,” says Mr. McHale with the firefighters union.

Besides providing money to upgrade the fire engines that must traverse the mammoth state and wind along serpentine canyon roads, the state has invested in better command-and-control facilities as well as the strategies to run them. “In the fire sieges of earlier years, we found out that we had the willingness of mutual-aid help from other jurisdictions and states, but we were not able to communicate adequately with them,” says Kim Zagaris, chief of the state’s Office of Emergency Services, fire and rescue branch. After a 2004 blue-ribbon commission examined and revamped those procedures, the statewide response “has become far more professional and responsive,” he says.

Besides ordering the California National Guard on Monday to make 1,500 guardsmen available for firefighting efforts, Gov. Arnold Schwarzenegger asked the Pentagon to send all available Modular Airborne Fighting Systems to the area. The military Lockheed C-130 cargo/utility aircraft carry a pressurized 3,000-gallon tank that can eject fire retardant or water in fewer than five seconds through two tubes at the rear of the plane. This load can cover an area 1/4-mile long and 60 feet wide to create a fire barrier. Governor Schwarzenegger also directed 2,300 inmate firefighters and 170 custody staff from the California Department of Corrections and Rehabilitation to work hand in hand with state and local firefighters.

Residents and government officials alike are noting the improvements with gratitude, even amid the loss of homes, churches, businesses, and farms. Despite such losses there is a sense that the speed, dedication, and coordination of firefighters from several states and jurisdictions are resulting in greater efficiency than in past “siege situations.

“I am extraordinarily impressed by the improvements we have witnessed between last big fire and this,” says Ross Simmons, a San Diego-based lawyer who ha evacuate both his home and business on Monday, taking up residence at a Hampton Inn 30 miles south of his home in Rancho Bernardo. After fires consumed 172,000 acres there in 2003, the San Diego region turned community wide soul-searching into improved building codes, evacuation procedures, and procurement of new technology. Mr. Simmons and neighbors began receiving automated phone calls at 3:30 a.m. Monday morning telling them to evacuate. “Notwithstanding all the damage that will be caused by this, we will not come close to the loss of life because of what we have … put in place since then,” he says.

Alfred Nobel

Since 1901, the Nobel Prize has been honoring men and women from all corners of the globe for outstanding achievements in physics, chemistry, medicine, literature, and for work in peace. The foundations for the prize were laid in 1895 when Alfred Nobel wrote his last will, leaving much of his wealth to the establishment of the Nobel Prize.

Alfred Nobel was born in Stockholm on October 21, 1833. His father Immanuel Nobel was an engineer and inventor who built bridges and buildings in Stockholm. In connection with his construction work Immanuel Nobel also experimented with different techniques for blasting rocks. Successful in his industrial and business ventures, Immanuel Nobel was able, in 1842, to bring his family to St. Petersburg. There, his sons were given a first class education by private teachers. The train included natural sciences, languages and literature. By the age of 17 Alfred Nobel was fluent in Swedish, Russian, French, English and German. His primary interests were in English literature and poetry as well as in chemistry and physics. Alfred’s father, who wanted his sons to join his enterprise as engineers, disliked Alfred’s interest in poetry and found his son rather introverted.

In order to widen Alfred’s horizons his father sent him abroad for further training in chemical engineering. During a two year period Alfred Nobel visited Sweden, Germany, France and the United States. In Paris, the city he came to like best, he worked in the private laboratory of Professor T. J. Pclouze, a famous chemist. There he met the young Italian chemist Ascanio Sobrero who, three years earlier, had invented nitroglycerine, a highly explosive liquid. But it was considered too dangerous to be of any practical use. Although its explosive power greatly exceeded that of gunpowder, the liquid would explode in a very unpredictable manner if subjected to heat and pressure. Alfred Nobel became very interested in nitroglycerine and how it could be put to practical use in construction work. He also realized that the safety problems had to be solved and a method had to be developed for the controlled detonation of nitroglycerine.

After his return to Sweden in 1863, Alfred Nobel concentrated on developing nitroglycerine as an explosive. Several explosions, including one (1864) in which his brother Emil and several other persons were killed, convinced the authorities that nitroglycerine production was exceedingly dangerous. They forbade further experimentation with nitroglycerine within the Stockholm city limits and Alfred Nobel had to move his experimentation to a barge anchored on Lake Malaren. Alfred was not discouraged and in 1864 he was able to start mass production of nitroglycerine. To make the handling of nitroglycerine safer Alfred Nobel experimented with different additives. He soon found that mixing nitroglycerine with kieselguhr would turn the liquid into a paste which could be shaped into rods of a size and form suitable for insertion into drilling holes. In 1867 he patented this material under the name of dynamite. To be able to detonate the dynamite rods he also invented a detonator (blasting cap) which could be ignited by lighting a fuse. These inventions were made at the same time as the pneumatic drill came into general use. Together these inventions drastically reduced the cost of blasting rock, drilling tunnels, building canals and many other forms of construction work.

The market for dynamite and detonating caps grew very rapidly and Alfred Nobel also proved himself to be a very skillful entrepreneur and businessman. Over the years he founded factories and laboratories in some 90 different places in more than 20 countries. Although he lived in Paris much of his life he was constantly traveling. When he was not traveling or engaging in business activities Nobel himself worked intensively in his various laboratories, first in Stockholm and later in other places. I le focused on the development of explosives technology as well as other chemical inventions including such materials as synthetic rubber and leather, artificial silk, etc. By the time of his death in 1896 he had 355 patents.

Intensive work and travel did not leave much time for a private life. At the age of 43 he was feeling like an old man. At this time he advertised in a newspaper “wealthy, highly-educated elderly gentleman seeks lady of mature age, versed in languages, as secretary and supervisor of household.” The most qualified applicant turned out to be an Austrian woman, Countess Bertha Kinsky. After working a very short time for Nobel she decided to return to Austria to marry Count Arthur von Suttner. In spite of this Alfred Nobel and Bertha von Suttner remained friends and kept writing letters to each other for decades. Over the years Bertha von Suttner became increasingly critical of the arms race. She wrote a famous book, Lay Down Your Arms and became a prominent figure in the peace movement. No doubt this influenced Alfred Nobel when he wrote his final will which was to include a Prize for persons or organizations who promoted peace. Several years after the death of Alfred Nobel, the Norwegian Storting (Parliament) decided to award the 1905 Nobel Peace Prize to Bertha von Suttner.

Alfred Nobel died in San Remo, Italy, on December 10, 1896. When his will was opened it came as a surprise that his fortune was to be used for Prizes in Physics, Chemistry, Physiology or Medicine, Literature and Peace. The executors of his will were two young engineers, Ragnar Sohlman and Rudolf Lilljequist. They set about forming the Nobel Foundation as an organization to take care of the financial assets left by Nobel for this purpose and to coordinate the work of the Prize-Awarding Institutions. This was not without its difficulties since the will was contested by relatives and questioned by authorities in various countries.

Alfred Nobel’s greatness lay in his ability to combine the penetrating mind of the scientist and inventor with the forward-looking dynamism of the industrialist. Nobel was very interested in social and peace-related issues and held what were considered radical views in his era. He had a great interest in literature and wrote his own poetry and dramatic works. The Nobel Prizes became an extension and a fulfillment of his lifetime interests.

Health In The Wild

Many animals seem able to treat their illnesses themselves. Humans may have a thing or two to learn from them. For the past decade Dr Engel, a lecturer in environmental sciences at Britain’s Open University, has been collating examples of self-medicating behaviour in wild animals. She recently published a book on the subject. In a talk at the Edinburgh Science Festival earlier this month, she explained that the idea that animals can treat themselves has been regarded with some scepticism by her colleagues in the past. But a growing number of animal behaviourists now think that wild animals can and do deal with their own medical needs.

One example of self-medication was discovered in 1987. Michael Huffman and Mohamedi Seifu, working in the Mahale Mountains National Park in Tanzania, noticed that local chimpanzees suffering from intestinal worms would dose themselves with the pith of a plant called Veronia. This plant produces poisonous chemicals called terpenes. Its pith contains a strong enough concentration to kill gut parasites, but not so strong as to kill chimps (nor people, for that matter; locals use the pith for the same purpose). Given that the plant is known locally as “goat- killer”, however, it seems that not all animals are as smart as chimps and humans. Some consume it indiscriminately, and succumb.

Since the Veronia-eating chimps were discovered, more evidence has emerged suggesting that animals often eat things for medical rather than nutritional reasons. Many species, for example, consume dirt—a behaviour known as geophagy. Historically, the preferred explanation was that soil supplies minerals such as salt. But geophagy occurs in areas where the earth is not a useful source of minerals, and also in places where minerals can be more easily obtained from certain plants that are known to be rich in them. Clearly, the animals must be getting something else out of eating earth.

The current belief is that soil—and particularly the clay in it—helps to detoxify the defensive poisons that some plants produce in an attempt to prevent themselves from being eaten. Evidence for the detoxifying nature of clay came in 1999, from an experiment carried out on macaws by James Gilardi and his colleagues at the University of California, Davis. Macaws eat seeds containing alkaloids, a group of chemicals that has some notoriously toxic members, such as strychnine. In the wild, the birds are frequently seen perched on eroding riverbanks eating clay. Dr Gilardi fed one group of macaws a mixture of harmless alkaloid and clay, and a second group just the alkaloid. Several hours later, the macaws that had eaten the clay had 60% less alkaloid in their bloodstreams than those that had not, suggesting that the hypothesis is correct.

Other observations also support the idea that clay is detoxifying. Towards the tropics the amount of toxic compounds in plants increases-and so does the amount of earth eaten by herbivores. Elephants lick clay from mud holes all year round, except in September when they are bingeing on fruit which, because it has evolved to be eaten, is not toxic. And the addition of clay to the diets of domestic cattle increases the amount of nutrients that they can absorb from their food by 10-20%.

A third instance of animal self-medication is the use of mechanical scours to get rid of gut parasites, in 1972 Richard Wrangham, a researcher at the Gombe Stream Reserve in Tanzania, noticed that chimpanzees were eating the leaves of a tree called Aspilia. The chimps chose the leaves carefully by testing them in their mouths. Having chosen a leaf, a chimp would fold it into a fan and swallow it. Some of the chimps were noticed wrinkling their noses as they swallowed these leaves, suggesting the experience was unpleasant. Later, undigested leaves were found on the forest floor.

Dr Wrangham rightly guessed that the leaves had a medicinal purpose—this was, indeed, one of the earliest interpretations of a behaviour pattern as self-medication. However, he guessed wrong about what the mechanism was. His (and everybody else’s) assumption was that Aspilia contained a drug, and this sparked more than two decades of phytochemical research to try to find out what chemical the chimps were after. But by the 1990s, chimps across Africa had been seen swallowing the leaves of 19 different species that seemed to have few suitable chemicals in common. The drug hypothesis was looking more and more dubious.

It was Dr Huffman who got to the bottom of the problem. He did so by watching what came out of the chimps, rather than concentrating on what went in. He found that the egested leaves were full of intestinal worms. The factor common to all 19 species of leaves swallowed by the chimps was that they were covered with microscopic hooks. These caught the worms and dragged them from their lodgings.

Following that observation, Dr Engel is now particularly excited about how knowledge of the way that animals look after themselves could be used to improve the health of live-stock. People might also be able to learn a thing or two, and may, indeed, already have done so. Geophagy, for example, is a common behaviour in many parts of the world The medical stalls in African markets frequently sell tablets made of different sorts of clays, appropriate to different medical conditions.

Africans brought to the Americas as slaves continued this tradition, which gave their owners one more excuse to affect to despise them. Yet, as Dr Engel points out, Rwandan mountain gorillas eat a type of clay rather similar to kaolinite – the main ingredient of many patent medicines sold over the counter in the West for digestive complaints. Dirt can sometimes be good for you, and to be “as sick as a parrot” may, after all, be a state to be desired.

The Conquest Of Malaria In Italy

A. Everybody now knows that malaria is carried by mosquitoes. But in the 19th century, most experts believed that the disease was produced by “miasma” or “poisoning of the air”. Others made a link between swamps, water and malaria, but did not make the further leap towards insects. The consequences of these theories were that little was done to combat the disease before the end of the century. Things became so bad that 11m Italians (from a total population of 25m) were “permanently at risk”. In malarial zones the life expectancy of land workers was a terrifying 22.5 years. Those who escaped death were weakened or suffered from splenomegaly — a “painful enlargement of the spleen” and “a lifeless stare”. The economic impact of the disease was immense. Epidemics were blamed on southern Italians, given the widespread belief that malaria was hereditary. In the 1880s, such theories began to collapse as the dreaded mosquito was identified as the real culprit.

B. Italian scientists, drawing on the pioneering work of French doctor Alphonse Laveran, were able to predict the cycles of fever but it was in Rome that further key discoveries were made. Giovanni Battista Grassi, a naturalist, found that a particular type of mosquito was the carrier of malaria. By experimenting on healthy volunteers (mosquitoes were released into rooms where they drank the blood of the human guinea pigs), Grassi was able to make the direct link between the insects (all females of a certain kind) and the disease. Soon, doctors and scientists made another startling discovery: the mosquitoes themselves were also infected and not mere carriers. Every year, during the mosquito season, malarial blood was moved around the population by the insects. Definitive proof of these new theories was obtained after an extraordinary series of experiments in Italy, where healthy people were introduced into malarial zones but kept free of mosquito bites — and remained well. The new Italian state had the necessary information to tackle the disease.

C. A complicated approach was adopted, which made use of quinine – a drug obtained from tree bark which had long been used to combat fever, but was now seen as a crucial part of the war on malaria. Italy introduced a quinine law and a quinine tax in 1904, and the drug was administered to large numbers of rural workers. Despite its often terrible side-effects (the headaches produced were known as the “quinine-buzz”) the drug was successful in limiting the spread of the disease, and in breaking cycles of infection. In addition, Italy set up rural health centres and invested heavily in education programmes. Malaria, as Snowden shows, was not just a medical problem but a social and regional issue, and could only be defeated through multi-layered strategies. Politics was itself transformed by the anti malarial campaigns. It was originally decided to give quinine to all those in certain regions – even healthy people; peasants were often suspicious of medicine being forced upon them. Doctors were sometimes met with hostility and refusal, and many were dubbed “poisoners”.

D. Despite these problems, the strategy was hugely successful. Deaths from malaria fell by some 80% in the first decade of the 20th century and some areas escaped altogether from the scourge of the disease. War, from 1915-18, delayed the campaign. Funds were diverted to the battlefields and the fight against malaria became a military issue, laying the way for the fascist approach to the problem. Mussolini’s policies in the 20s and 30s are subjected to a serious cross-examination by Snowden. He shows how much of the regime’s claims to have “eradicated” malaria through massive land reclamation, forced population removals and authoritarian clean-ups were pure propaganda. Mass draining was instituted — often at a great cost as Mussolini waged war not on the disease itself, but on the mosquitoes that carried it. The cleansing of Italy was also ethnic, as “carefully selected” Italians were chosen to inhabit the gleaming new towns of the former marshlands around Rome. The “successes” under fascism were extremely vulnerable, based as they were on a top-down concept of eradication. As war swept through the drained lands in the 40s, the disease returned with a vengeance.

E. In the most shocking part of the book, Snowden describes — passionately, but with the skill of a great historian — how the retreating Nazi armies in Italy in 1943-44 deliberately caused a massive malaria epidemic in Lazio. It was “the only known example of biological warfare in 20th-century Europe”. Shamefully, the Italian malaria expert Alberto Missiroli had a role to play in the disaster: he did not distribute quinine, despite being well aware of the epidemic to come. Snowden claims that Missiroli was already preparing a new strategy — with the support of the US Rockefeller Foundation — using a new pesticide, DDT Missiroli allowed the epidemic to spread, in order to create the ideal conditions for a massive, and lucrative, human experiment. Fifty-five thousand cases of malaria were recorded in the province of Littoria alone in 1944. It is estimated that more than a third of those in the affected area contracted the disease. Thousands, nobody knows how many, died. With the war over, the US government and the Rockefeller Foundation were free to experiment. DDT was sprayed from the air and 3m Italians had their bodies covered with the chemical. The effects were dramatic, and nobody really cared about the toxic effects of the chemical.

F. By 1962, malaria was more or less gone from the whole peninsula. The last cases were noted in a poor region of Sicily. One of the final victims to die of the disease in Italy was the popular cyclist, Fausto Coppi. He had contracted malaria in Africa in 1960, and the failure of doctors in the north of Italy to spot the disease was a sign of the times. A few decades earlier they would have immediately noticed the tell-tale signs; it was later claimed that a small dose of quinine would have saved his life. As there are still more than 1m deaths every year from malaria worldwide, Snowden’s book also has contemporary relevance. This is a disease that affects every level of the societies where it is rampant. It also provides us with “a message of hope for a world struggling with the great present-day medical emergency”.

Sunset For The Oil Business

The world is about to run out of oil. Or perhaps not. It depends whom you believe… Members of Oil Depletion Analysis Centre (ODAC) recently met in London and presented technical data that support their grim forecast that the world is perilously dose to running out of oil. Leading lights of this movement, including Colin Campbell, rejected rival views presented by American Geological Survey and the International Energy Agency (IEA) that contradicted their views. Dr Campbell even decried the “amazing display of ignorance, deliberate ignorance, denial and obfuscation” by governments, industry and academics on this topic.

So is the oil really running out? The answer is easy: Yes. Nobody seriously disputes the notion that oil is, for all practical purposes, a non-renewable resource that will run out some day, be that years or decades away. The harder question is determining when precisely oil will begin to get scarce. And answering that question involves scaling Hubbert’s peak.

M. King Hubbert, a Shell geologist of legendary status among depletion experts, forecast in 1956 that oil production in the United States would peak in the early 1970s and then slowly decline, in something resembling a bell-shaped curve. At the time, his forecast was controversial, and many rubbished it. After 1970, however, empirical evidence proved him correct: oil production in America did indeed peak and has been in decline ever since.

Dr Hubbert’s analysis drew on the observation that oil production in a new area typically rises quickly at first, as the easiest and cheapest reserves are tapped. Over time, reservoirs age and go into decline, and so lifting oil becomes more expensive. Oil from that area then becomes less competitive in relation to other sources of fuel. As a result, production slows down and usually tapers off and declines. That, he argued, made for a bell-shaped curve.

His successful prediction has emboldened a new generation of geologists to apply his methodology on a global scale. Chief among them are the experts at ODAC, who worry that the global peak in production will come in the next decade. Dr Campbell used to argue that the peak should have come already; he now thinks it is just round the corner. A heavyweight has now joined this gloomy chorus. Kenneth Deffeyes of Princeton University argues in a that global oil production could peak within the next few years.

That sharply contradicts mainstream thinking. America’s Geological Survey prepared an exhaustive study of oil depletion last year that put the peak of production some decades off. The IEA has just weighed in with its new “World Energy Outlook” which foresees enough oil to comfortably meet demand to 2020 from remaining reserves. Rene Dahan, one of ExxonMobil’s top managers, goes further: with an assurance characteristic of the world’s largest energy company, he insists: that the world will be awash in oil for another 70 years. Who is right? In making sense of these wildly opposing views, it is useful to look back at the pitiful history of oil forecasting. Doomsters have been predicting dry wells since the 1970s, but so far the oil is still gushing Nearly all the predictions for 2000 made after the 1970s oil shocks were far too pessimistic.

Michael Lynch of DRI-WEFA, an economic consultancy, is one of the few oil forecasters who has got things generally right. In a new paper, Dr Lynch analyses those historical forecasts. He finds evidence of both bias and recurring errors, which suggests that methodological mistakes (rather than just poor data) were the problem. In particular, he criticized forecasters who used Hubbert-style analysis for relying on fixed estimates of how much “ultimately recoverable” oil there really is below ground. That figure, he insists, is actually a dynamic one, as improvements in infrastructure, knowledge and technology raise the amount of oil which is recoverable.

That points to what will probably determine whether the pessimists or the optimists are right: technological innovation. The first camp tends to be dismissive of claims of forthcoming technological revolutions in such areas as deep-water drilling and enhanced recovery. Dr Deffeyes captures this end-of- technology mindset well. He argues that because the industry has already spent billions on technology development, it makes it difficult to ask today for new technology, as most of the wheels have already been invented.

Yet techno-optimists argue that the technological revolution in oil has only just begun. Average recovery rates (how much of the known oil in a reservoir can actually be brought to the surface) are still only around 30-35%. Industry optimists believe that new techniques on the drawing board today could lift th figure to 50-60% within a decade.

Given the industry’s astonishing track record of innovation, it may be foolish to bet against it. That is the result of adversity: the oil crisis of the 1970s forced Big Oil to develop reserves in expensive, inaccessible places such as the North and Alaska, undermining Dr Hubbert’s assumption that cheap reserves are developed first. The resulting upstream investments have driven down the cost of finding and developing wells over the last two decades from over $20 a barrel to around $6 a barrel. The cost of producing oil has fallen by half, to under $4 a barrel.

Such miracles will not come cheap, however, since much of the world’s oil is now produced in ageing fields that are rapidly declining. The IEA concludes that global oil production need not peak in the next two decades if the necessary investments are made. So how much is necessary? If oil companies are to replace the output lost at those ageing fields and meet the worlds ever-rising demand for oil, the agency reckons they must invest $1 trillion in l non-OPEC countries over the next decade alone. Ouch.

The World Is Our Oyster

A Independent travel is on the increase and while package holidays which offer an all inclusive price for transport, accommodation and often even food are financially attractive to many, according to tourism analyst Thomas Cooper, an increasing number of people now prefer a less-tailored holiday and the freedom to make spur of the moment decisions and changes to their intended plan.

B Internet based information sites about backpacking destinations are prolific and publications aimed at independent travellers on a budget exist for almost every destination imaginable. Some people, particularly first-time backpackers, may elect to travel with a friend or acquaintance; however, a large percentage of backpackers travel alone, assured by the knowledge that they are likely to meet, with ease, a number of like-minded individuals throughout their journey and staying in their backpacker accommodation. Alan Park, who has travelled extensively through Europe, Australasia and several other parts of the globe, says most accommodation establishments aimed at the backpacker market are designed with communal kitchens, dormitories and entertainment areas which lend themselves to allowing residents to socialize with ease and quickly breakdown barriers with strangers that may usually exist in day to day life.

C Many backpackers of European origin are attracted to the Southern Hemisphere, Australia being a major destination of choice. Cooper attributes this high level of interest to the possibilities of legal working holiday visas for many nationalities and consequent short-term work opportunities making extended travel financially feasible, in addition to the attractive climate and outback appeal. Australia also has the reputation of being a relatively safe destination, with a warm and jovial population and its size and contrast between locations is alluring to many. University student Rebecca Thompson, who has just returned from a twelve month overseas trip, says that the cosmopolitan and modern nature of Australian cities such as Sydney and Melbourne contrasted with the rugged outback appeal of Western Australia and the Northern Territory, or the marine paradise of the Great Barrier Reef offer sufficient variation to attract a wide base of visitors. Sydney based travel consultant Brad Connor advises that it is also possible to obtain bargain deals on internal flights within this massive island when purchasing an international ticket, highly recommended, he says, for those who do not have the luxury of a long length of time, in order to ensure that key spots can be visited.

D Equal in popularity to Australia, for the backpacking market is South East Asia and Rebecca Thompson says that, in her experience, the majority of travellers on extended trips to Australasia also include a visit to one or more South East Asia destinations in their itinerary. Thailand, in particular, has a long tourism history and well-established service industry. It is often considered one of the more accessible Asian destinations for the novice European backpacker due to its reasonable prices, large volume of Western visitors and well established backpacker trails. Brian Johnson, who is currently employed by the British Consulate in Bangkok, believes that the welcoming nature and level of English spoken by Thais involved in the tourism industry has also impacted positively on the destination’s overseas image. Thai food is delicious and now fairly familiar to those outside the country and while precautions such as drinking bottled water and washing of fruit and vegetables should be practiced, generally standards of accommodation and restaurants are high. Thomas Cooper says Thailand’s attractions are wide ranging, encompassing idyllic beaches, an insight into Buddhist culture and impressive ancient temples, mountain trekking, a vibrant nightlife and for bargain hunters bustling night markets and bazaars.

E South East Asia neighbour, Vietnam, alongside its rapidly developing economy has also over recent years established a solid tourism industry, the majority of visitors entering and exiting by plane via its urban centres Ho Chi Minh (formerly Saigon) in the south and Hanoi in the north. Vietnam offers incredible vistas and contrasts of rugged mountain areas, lush green rice paddies, crystal clear waters and dense forest areas. Alan Park, who spent a month travelling independently around the country, says bus and rail networks allow visitors to travel from centre to centre relatively inexpensively, though he does not recommend these forms of transport to visitors on a short time-frame as the pace is unhurried.

F The list of potentially safe and enjoyable backpacking destinations is endless. Technology and transport developments over recent time have resulted in more areas of the world becoming increasingly accessible, it is now possible to keep in regular contact with friends and family back home via email or even mobile phone, providing added reassurance to those concerned about travelling and their worried parents. Brian Johnson says friends, family and acquaintances who have previously travelled to the destination of choice are a useful source of first-hand advice and information and Simon Hartwell of the Backpackers Association adds travellers are advised to ensure that they are aware of visa requirements for their destination and are urged to seek medical advice regarding any necessary vaccinations or medical precautions. It is always wise to be as well informed as possible prior to embarking on a trip.

G The youth of today are undoubtedly becoming more adventurous, which Hartwell ascribes to higher disposable income in the developed world than were available to previous generations and also the fact that we can more easily familiarise ourselves with the unknown via the internet and other communication methods. Many travellers, particularly experienced backpackers, are keen to experience more obscure destinations well off the well-trodden
backpacker trail.

An Aviation Wonder And Its Creator

A The Supermarine Spitfire was a single-seater fighter plane used by the British Royal Airforce and pilots from a number of the country’s allies during the Second World War. The first flight of a Spitfire prototype was on 5 March 1936 and usage of the plane continued until the 1950s. It was said to be one of the most effective fighter planes available during that period and was produced by Vickers-Armstrongs, a British engineering corporation which was formed in 1927 as a result of the merger of Vickers Limited and Sir W G Armstrong Whitworth & Company.

B The Spitfire was designed by aeronautical engineer Reginald Joseph Mitchell. His career began when he joined a locomotives engineering company in 1911 at the age of 16. However, in 1917 he moved from his home town to join the Supermarine Aviation works in Southampton and was promoted to Chief Designer within his first year of employment. By the time the company was taken over by Vickers-Armstrongs in 1928, Mitchell had held the post of Technical Director for a year; and his capabilities and contributions were deemed so significant Vickers-Armstrong made his continual employment for a five year period a condition of the purchase of the company.

C In the fifteen years prior to 1936 Mitchell designed 24 aircraft of differing categories including fighter planes, bombers and seaplanes. The first predecessor of the Spitfire in the fighter plane category to gain him national acclaim was the Supermarine S.B for which he won the Schneider Trophy (a cup and monetary award for technical advances in aviation which came to focus mainly on speed) in 1931. Despite withdrawal of financial support from the British Government that year, the Supermarine S.B. was able to compete for the Schneider Trophy as a result of a private donation of 100,000 pounds. Mitchell’s team won outright on September 13th their aircraft achieving a new world speed record of 606 km/h; within days the Supermarine S.B. went on to break its own newly achieved record when on the 29th of the same month it became the first aircraft ever to achieve speeds of over 400 miles per hour (640 kilometres) when it reached 407.5 mph (640 kilometres per hour).

D Reginald Joseph Mitchell was awarded a CBE in 1932 for his contributions to high speed flight. CBEs being awarded by the British Monarch and reserved to recognise individuals who have ‘fulfilled a conspicuous leading role in regional affairs, through achievement or service to the community, or making a highly distinguished, innovative contribution in his or her area of activity’. Mitchell’s achievements with the Supermarine S.B. also prompted the Air Ministry to contract his company for design of a new fighter aircraft, despite the organisation’s reputation being built predominantly on sea-plane and not fighter plane manufacturing.

E The first type, the 224, was to prove unsuccessful and it was eventually rejected by the Royal Air Force due to unsatisfactory performance; however, private sponsorship enabled research, development and modifications which led to the creation of the Type 300 which would eventually become the Spitfire. Soon after the first flight of the Spitfire prototype (trial version) and prior to completion of all stages of its official trials, convinced by its potential, the British Royal Air Force ordered 310 models. With its smooth lines, load-bearing metal shell, and heavy eight-machine gun armament, the Spitfire was considered revolutionary. In 1938, the aircraft was first put into official service; however, Mitchell, who died from cancer in 1937 at the age of 42, was not to witness this or the extensive impact and longevity of use the aircraft would have. In total 20,351 spitfires of different versions were produced making it the most produced British aircraft of the Second World War.

F After Mitchell’s death, his former Chief Draughtsman Joe Smith took over the position of Technical Director and led the subsequent development of the Spitfire which would keep it at the forefront of aircraft technology while many other designs quickly became obsolete; 24 models of spitfire were designed along with many sub-variants containing different engine types and possessing different wing configurations; the most widely used being the Spitfire Mark V, of which 6,479 were built. The original version first used for active service in 1938 had a top speed of approximately 580 km per hour; while one of the last models used in the later stages of the Second World War – the Spitfire XIV – had a top speed capability of 710 km per hour. Spitfires were used continually by the Royal Air Force, later purely as surveillance planes (to monitor activity overhead though carrying no armament), until 1954 when the last model was retired.

G In his home town, Reginald Joseph Mitchell C.B.E. is today remembered in a number of ways. A combined theatre and education centre ‘The Mitchell Memorial Theatre’ bears his name, and the city museum, at the entrance of which stands a bronze statue of Mitchell, displays an authentic and complete Spitfire as part of its collection. In addition, a local high school is named after him; as is a major roadway and he is locally recognised as one of the most significant historical sons of the town.

Nature’s Most Violent Wind

A Tornados have been observed in every continent on the planet with the exception of Antarctica. Hurricanes differ from tornadoes, in that the former develop in warm, tropical oceans whereas tornados develop on land and are more aggressive and potentially destructive. The majority of tornados are initiated by thunderstorms. Tornados are relatively common occurrences at differing magnitudes throughout the world. The geographical features of the U.S.A. lend themselves to high incidence of tornado activity. In that country the highest proportion of tornados occur in the southern states in spring from March to May and in the northern states from late spring extending into summer. Generally tornados travel from southwest to northeast, though neither time of year nor direction they will take is completely predictable.

B Several factors cause the U.S.A. to experience a high incidence of tornado formation. While the continent reaches from arctic areas in the north to a tropical climate in the south there is no barrier protection from significant mountain ranges in the east or west; however, the Rocky Mountains in the middle latitudes of the country obstruct atmospheric flow and moisture. In addition, drier air from the southwest deserts and low level moisture from the Gulf of Mexico meet in the area, many collisions of warm and cool air occur and optimum conditions for tornado formation are created. Tornados in this central part of the U.S.A. are so prolific that the area has been named Tornado Alley, the site of the highest number of powerful tornados in the country and throughout the world. In the USA alone, in an average year 1200 tornados occur causing 70 fatalities and 1500 injuries and in addition extensive
damage to property and natural vegetation.

C Connected between a cloud base above (usually cumulonimbus) and the earth below, a tornado is a rapidly rotating column of air; they can be as much as 20 kilometres in height. The majority are less than 75 metres in diameter reaching wind speeds of less than 177kms per hour and travel less than 10 kilometres before dissipating; however, some of the larger and rarer of this type of weather phenomenon may reach wind speeds of more than 480kms/hour traveling more than 100 kilometers before cessation. The inside of a tornado is made up of descending air and this is surrounded by a spiraling upward current which has the ability to carry with it and destroy even substantial obstacles such as tress, cars and houses in its path. Scientific research and eyewitness accounts indicate that most tornados also possess a calm centre in their core, surrounded by the layers of the downward and upward currents of air; this core has been likened to the peaceful central ‘eye’ at the centre of a tropical cyclone or hurricane.

D A tornado itself is not necessarily visible; though the intense low pressure it causes often results in condensation of water vapour which forms into a noticeable condensation funnel. Colours of tornados are also dictated by the environment in which they form. The force of the swirling air causes them to pick up dirt as they travel across the landscape; those with minimal debris remaining grey or white turning darker blue the more they collect, while others in areas such the Great Plains in the USA turn red in colour due to the red soil they collect and carry with them. Background lighting in which a tornado presents itself also affects the naked eye’s ability to identify its form as it appears on the horizon. When viewing a tornado with the sun behind it, it will appear to be dark in colour; however, when viewed without the sun in the background, the same tornado appears to be grey or white. On the rare occasions that tornados occur after dark, they pose an increased level of danger as darkness can make them invisible and only radar warnings or possibly sound can warn those in their path that a tornado is on its way.

E Tornados are classified into three levels of intensity; these being weak, strong and violent. 88% of tornados occurring in the USA are classified into the first category making them the most common; they account for less than 5% of fatalities resulting from tornado activity, generally reach wind speeds of less than 177kms/hour and have a duration of between 1 and 10 minutes before cessation. In contrast, ‘violent’ tornados exceed 330 kilometres per hour, can continue for over an hour and while they account for only 1% of incidence of tornados they result in approximately 70% of resultant deaths. The greatest devastation to date, inflicted on the USA by a violent tornado was on March 18th, 1925. The tornado was the longest, fastest and widest tornado known to have formed in North America and resulted in 695 deaths, an additional 2279 being injured. Now known as the Tri-state Tornado, it travelled over 350 kilometres affecting 13 counties in the three different states of Missouri, Illinois and Indiana. Around 11% of tornados are classified as ‘strong’ tornados. These tornados account for slightly more than 25% of tornado-related fatal accidents and reach mid-range speeds of between 177 and 330 kilometres per hour with an average duration of around 20 minutes.

F Today in the USA, early warning systems, which cannot necessarily protect property in the path of a tornado, can allow people time to leave the area and therefore significantly reduce death tolls. However in countries such as Bangladesh, fatalities caused by tornado impact remain extremely high. The rural, central region of the country also experiences a high frequency of strong tornados and the danger is exacerbated due to its densely populated areas, lack of warning systems and vulnerability of building structures. Between 1967 and 1996 the Bangladesh Observer and Pakistan Observer reported 5,373 tornado related deaths: an average of 179.1 per year. The Manikganj Tornado which occurred in 1989 is thought to have caused as a many as 1300 deaths and is known as the deadliest tornado to have occurred anywhere in the world. Many projects delivered by organizations such as the Asian Disaster Reduction Centre (ADRC) have been established with the aim of minimising devastation and death rates caused by tornados in such areas.

The secret of staying young

Pheidole dentata, a native ant of the south-eastern U.S., isn’t immortal. But scientists have found that it doesn’t seem to show any signs of aging. Old worker ants can do everything just as well as the youngsters, and their brains appear just as sharp. ‘We get a picture that these ants really don’t decline,’ says Ysabel Giraldo, who studied the ants for her doctoral thesis at Boston University.

Such age-defying feats are rare in the animal kingdom. Naked mole rats can live for almost 30 years and stay fit for nearly their entire lives. They can still reproduce even when old, and they never get cancer. But the vast majority of animals deteriorate with age just like people do. Like the naked mole rat, ants are social creatures that usually live in highly organised colonies. ‘It’s this social complexity that makes P. dentata useful for studying aging in people,’ says Giraldo, now at the California Institute of Technology. Humans are also highly social, a trait that has been connected to healthier aging. By contrast, most animal studies of aging use mice, worms or fruit flies, which all lead much more isolated lives.

In the lab, P. dentata worker ants typically live for around 140 days. Giraldo focused on ants at four age ranges: 20 to 22 days, 45 to 47 days, 95 to 97 days and 120 to 122 days. Unlike all previous studies, which only estimated how old the ants were, her work tracked the ants from the time the pupae became adults, so she knew their exact ages. Then she put them through a range of tests.

Giraldo watched how well the ants took care of the young of the colony, recording how often each ant attended to, carried and fed them. She compared how well 20-day-old and 95-day-old ants followed the telltale scent that the insects usually leave to mark a trail to food. She tested how ants responded to light and also measured how active they were by counting how often ants in a small dish walked across a line. And she experimented with how ants react to live prey: a tethered fruit fly. Giraldo expected the older ants to perform poorly in all these tasks. But the elderly insects were all good caretakers and trail-followers—the 95-day-old ants could track the scent even longer than their younger counterparts. They all responded to light well, and the older ants were more active. And when it came to reacting to prey, the older ants attacked the poor fruit fly just as aggressively as the young ones did, flaring their mandibles or pulling at the fly’s legs.

Then Giraldo compared the brains of 20-day-old and 95-day-old ants, identifying any cells that were close to death. She saw no major differences with age, nor was there any difference in the location of the dying cells, showing that age didn’t seem to affect specific brain functions. Ants and other insects have structures in their brains called mushroom bodies, which are important for processing information, learning and memory. She also wanted to see if aging affects the density of synaptic complexes within these structures—regions where neurons come together. Again, the answer was no. What was more, the old ants didn’t experience any drop in the levels of either serotonin or dopamine—brain chemicals whose decline often coincides with aging. In humans, for example, a decrease in serotonin has been linked to Alzheimer’s disease.

‘This is the first time anyone has looked at both behavioral and neural changes in these ants so thoroughly,’ says Giraldo, who recently published the findings in the Proceedings of the Royal Society B. Scientists have looked at some similar aspects in bees, but the results of recent bee studies were mixed—some studies showed age-related declines, which biologists call senescence, and others didn’t. ‘For now, the study raises more questions than it answers,’ Giraldo says, ‘including how P. dentata stays in such good shape.’

Also, if the ants don’t deteriorate with age, why do they die at all? Out in the wild, the ants probably don’t live for a full 140 days thanks to predators, disease and just being in an environment that’s much harsher than the comforts of the lab. ‘The lucky ants that do live into old age may suffer a steep decline just before dying,’ Giraldo says, but she can’t say for sure because her study wasn’t designed to follow an ant’s final moments.

‘It will be important to extend these findings to other species of social insects,’ says Gene E. Robinson, an entomologist at the University of Illinois at Urbana-Champaign. This ant might be unique, or it might represent a broader pattern among other social bugs with possible clues to the science of aging in larger animals. Either way, it seems that for these ants, age really doesn’t matter.

Why zoos are good

A In my view, it is perfectly possible for many species of animals living in zoos or wildlife parks to have a quality of life as high as, or higher than, in the wild. Animals in good zoos get a varied and high-quality diet with all the supplements required, and any illnesses they might have will be treated. Their movement might be somewhat restricted, but they have a safe environment in which to live, and they are spared bullying and social ostracism by others of their kind. They do not suffer from the threat or stress of predators, or the irritation and pain of parasites or injuries. The average captive animal will have a greater life expectancy compared with its wild counterpart, and will not die of drought, of starvation or in the jaws of a predator. A lot of very nasty things happen to truly ‘wild’ animals that simply don’t happen in good zoos, and to view a life that is ‘free’ as one that is automatically ‘good’ is, I think, an error. Furthermore, zoos serve several key purposes.

B Firstly, zoos aid conservation. Colossal numbers of species are becoming extinct across the world, and many more are increasingly threatened and therefore risk extinction. Moreover, some of these collapses have been sudden, dramatic and unexpected, or were simply discovered very late in the day. A species protected in captivity can be bred up to provide a reservoir population against a population crash or extinction in the wild. A good number of species only exist in captivity, with many of these living in zoos. Still more only exist in the wild because they have been reintroduced from zoos, or have wild populations that have been boosted by captive bred animals. Without these efforts there would be fewer species alive today. Although reintroduction successes are few and far between, the numbers are increasing, and the very fact that species have been saved or reintroduced as a result of captive breeding proves the value of such initiatives.

C Zoos also provide education. Many children and adults, especially those in cities, will never see a wild animal beyond a fox or pigeon. While it is true that television documentaries are becoming ever more detailed and impressive, and many natural history specimens are on display in museums, there really is nothing to compare with seeing a living creature in the flesh, hearing it, smelling it, watching what it does and having the time to absorb details. That alone will bring a greater understanding and perspective to many, and hopefully give them a greater appreciation for wildlife, conservation efforts and how they can contribute.

D In addition to this, there is also the education that can take place in zoos through signs, talks and presentations which directly communicate information to visitors about the animals they are seeing and their place in the world. This was an area where zoos used to be lacking, but they are now increasingly sophisticated in their communication and outreach work. Many zoos also work directly to educate conservation workers in other countries, or send their animal keepers abroad to contribute their knowledge and skills to those working in zoos and reserves, thereby helping to improve conditions and reintroductions all over the world.

E Zoos also play a key role in research. If we are to save wild species and restore and repair ecosystems we need to know about how key species live, act and react. Being able to undertake research on animals in zoos where there is less risk and fewer variables means real changes can be effected on wild populations. Finding out about, for example, the oestrus cycle of an animal or its breeding rate helps us manage wild populations. Procedures such as capturing and moving at-risk or dangerous individuals are bolstered by knowledge gained in zoos about doses for anaesthetics, and by experience in handling and transporting animals. This can make a real difference to conservation efforts and to the reduction of human-animal conflicts, and can provide a knowledge base for helping with the increasing threats of habitat destruction and other problems.

F In conclusion, considering the many ongoing global threats to the environment, it is hard for me to see zoos as anything other than essential to the long-term survival of numerous species. They are vital not just in terms of protecting animals, but as a means of learning about them to aid those still in the wild, as well as educating and informing the general population about these animals and their world so that they can assist or at least accept the need to be more environmentally conscious. Without them, the world would be, and would increasingly become, a much poorer place.

READING PASSAGE 3

Chelsea Rochman, an ecologist at the University of California, Davis, has been trying to answer a dismal question: Is everything terrible, or are things just very, very bad?

Rochman is a member of the National Center for Ecological Analysis and Synthesis’s marine-debris working group, a collection of scientists who study, among other things, the growing problem of marine debris, also known as ocean trash. Plenty of studies have sounded alarm bells about the state of marine debris; in a recent paper published in the journal Ecology, Rochman and her colleagues set out to determine how many of those perceived risks are real.

Often, Rochman says, scientists will end a paper by speculating about the broader impacts of what they’ve found. For example, a study could show that certain seabirds eat plastic bags, and go on to warn that whole bird populations are at risk of dying out. ‘But the truth was that nobody had yet tested those perceived threats,’ Rochman says. ‘There wasn’t a lot of information.’

Rochman and her colleagues examined more than a hundred papers on the impacts of marine debris that were published through 2013. Within each paper, they asked what threats scientists had studied – 366 perceived threats in all – and what they’d actually found.

In 83 percent of cases, the perceived dangers of ocean trash were proven true. In the remaining cases, the working group found the studies had weaknesses in design and content which affected the validity of their conclusions – they lacked a control group, for example, or used faulty statistics.

Strikingly, Rochman says, only one well-designed study failed to find the effect it was looking for, an investigation of mussels ingesting microscopic plastic bits. The plastic moved from the mussels’ stomachs to their bloodstreams, scientists found, and stayed there for weeks – but didn’t seem to stress out the shellfish.

While mussels may be fine eating trash, though, the analysis also gave a clearer picture of the many ways that ocean debris is bothersome.

Within the studies they looked at, most of the proven threats came from plastic debris, rather than other materials like metal or wood. Most of the dangers also involved large pieces of debris – animals getting entangled in trash, for example, or eating it and severely injuring themselves.

But a lot of ocean debris is ‘microplastic’, or pieces smaller than five millimeters. These may be ingredients used in cosmetics and toiletries, fibers shed by synthetic clothing in the wash, or eroded remnants of larger debris. Compared to the number of studies investigating large-scale debris, Rochman’s group found little research on the effects of these tiny bits. ‘There are a lot of open questions still for microplastic,’ Rochman says, though she notes that more papers on the subject have been published since 2013, the cutoff point for the group’s analysis.

There are also, she adds, a lot of open questions about the ways that ocean debris can lead to sea-creature death. Many studies have looked at how plastic affects an individual animal, or that animal’s tissues or cells, rather than whole populations. And in the lab, scientists often use higher concentrations of plastic than what’s really in the ocean. None of that tells us how many birds or fish or sea turtles could die from plastic pollution – or how deaths in one species could affect that animal’s predators, or the rest of the ecosystem.

‘We need to be asking more ecologically relevant questions,’ Rochman says. Usually, scientists don’t know exactly how disasters such as a tanker accidentally spilling its whole cargo of oil and polluting huge areas of the ocean will affect the environment until after they’ve happened. ‘We don’t ask the right questions early enough,’ she says. But if ecologists can understand how the slow-moving effect of ocean trash is damaging ecosystems, they might be able to prevent things from getting worse.

Asking the right questions can help policy makers, and the public, figure out where to focus their attention. The problems that look or sound most dramatic may not be the best places to start. For example, the name of the ‘Great Pacific Garbage Patch’ – a collection of marine debris in the northern Pacific Ocean – might conjure up a vast, floating trash island. In reality though, much of the debris is tiny or below the surface; a person could sail through the area without seeing any trash at all. A Dutch group called ‘The Ocean Cleanup’ is currently working on plans to put mechanical devices in the Pacific Garbage Patch and similar areas to suck up plastic. But a recent paper used simulations to show that strategically positioning the cleanup devices closer to shore would more effectively reduce pollution over the long term.

‘I think clearing up some of these misperceptions is really important,’ Rochman says. Among scientists as well as in the media, she says, ‘A lot of the images about strandings and entanglement and all of that cause the perception that plastic debris is killing everything in the ocean.’ Interrogating the existing scientific literature can help ecologists figure out which problems really need addressing, and which ones they’d be better off- like the mussels – absorbing and ignoring.
