Design the mat and Foot health

A Indoor types will appreciate the cobblestone walkway, a knobbly textured plastic mat that they can wobble along in the comfort of their own homes. And for the more adventurous, there are shoes designed to throw you off balance.

B The technology may be cutting edge, but its origins are deep and exotic. Research into the idea that flat floors could be detrimental to our health was pioneered back in the late 1960s. While others in Long Beach, California, contemplated peace and love, podiatrist Charles Brantingham and physiologist Bruce Beekman were concerned with more pedestrian matters. They reckoned that the growing epidemic of high blood pressure, varicose veins and deep-vein thromboses might be linked to the uniformity of the surfaces that we tend to stand and walk on.

C The trouble, as they saw it, was that walking continuously on flat floors, sidewalks and streets concentrate forces on just a few areas of the foot. As a result, these surfaces are likely to be far more conducive to chronic stress syndromes than natural ones, where the foot meets the ground in a wide variety of orientations. The anatomy of the foot parallels that of the human hand – each having 26 bones, 33 joints and more than 100 muscles, tendons and ligaments. Modem lifestyles waste all this flexibility in your socks. Brantingham and Beekman became convinced that damage was being done simply by people standing on even surfaces and that this could be rectified by introducing a wobble.

D “In Beijing and Shanghai city dwellers take daily walks on cobbled paths to improve their health.” To test their ideas, they got 65 clerks and factory workers to try standing on a variable terrain floor – spongy mats with amounts of giving across the surface. This modest irregularity allowed the soles of the volunteers’ feet to deviate slightly from the horizontal each time they shifted position. As the researchers hoped, this simple intervention turned out to make a huge difference over just a few weeks. Just a slight wobble from the floor activated a host of muscles in people’s legs, which in turn helped to pump blood back to their hearts. The muscle action prevented the pooling of blood in their feet and legs, reducing the stress on the entire cardiovascular system. And two-thirds of the volunteers reported feeling much less tired. Yet decades later, the flooring of the world’s workplaces remains relentlessly smooth.

E Earlier this year, however, the idea was given a new lease of life when researchers in Oregon announced findings from a similar experiment with people over 60. John Fisher and colleagues at the Oregon Research Institute in Eugene designed a mat intended to replicate the effect of walking on cobblestones. In tests funded by the National Institute of Aging, they got some 50 adults to walk on the mats in their stockinged feet for less than an hour three times a week. After 16 weeks, these people showed marked improvements in balance and mobility, and even a significant reduction in blood pressure. People in a control group who walked on ordinary floors also improved but not as dramatically.

F The mats are now on sale at $35. “Our first 1000 cobblestone mats sold in three weeks,” Fisher says. Production is now being scaled up. Even so, demand could exceed supply if this foot-stimulating activity really is a “useful non-pharmacological approach for preventing or controlling hypertension of older adults”, as the researchers believe. They are not alone in extolling the revitalizing powers of cobblestones. Reflexologists have long advocated walking on textured surfaces to stimulate so-called “acupoints” on the soles of the feet. Practitioners of this unorthodox therapy believe that pressure applied to particular spots on the foot connects directly to corresponding organs and somehow enhances their function. In China, spas, hotels, apartment blocks and even factories promote their cobblestone paths as healthful amenities. Fisher admits he got the idea from regular visits to the country. In Beijing and Shanghai city dwellers take daily walks along cobbled paths to improve their health. “In the big cities, people take off their shoes and walk on these paths for 5 or 10 minutes, perhaps several times a day,” Fisher says.

G The idea is now taking off in Europe too. People in Germany, Austria and Switzerland can visit “barefoot parks” and walk along “paths of the senses” – with mud, logs, stone and moss underfoot – to receive what’s known there as reflexzon-massage. And it is not difficult to construct your own “health pathway”. American reflexologists Barbara and Kevin Kunz, based in Albuquerque, New Mexico, advise that you cobble together a walkway using broom handles, bamboo poles, hosepipes, gravel, pebbles, dried peas, driftwood, fallen logs, sand, door mats and strips of turf.

H If your enthusiasm for DIY doesn’t stretch to this, and Fisher’s cobblestone mats are all sold out, there is another option. A new shoe on the market claims to transform flat, hard, artificial surfaces into something like natural uneven ground. “These shoes have an unbelievable effect,” says Benno Nigg, an exercise scientist at the human performance laboratory of Calgary University in Canada, which has done contract research for the shoe’s manufacturers. “They are one of the best things to have happened to humankind for years.” Known as Masai Barefoot Technology, or MBTs, the shoes have rounded soles that cause you to rock slightly when you stand still, exercising the small muscles around the ankle that are responsible for fore-aft stability. Forces in the joint are reduced, putting less strain on the system, Nigg claims.

Brunel: ‘The Practical Prophet’

A In the frontispiece of his book on Brunel, Peter Hay quotes from Nicholson’s British Encyclopaedia of 1909 as follows: ‘Engineers are extremely necessary for these purposes; wherefore it is requisite that, besides being ingenious, they should be brave in proportion.’ His father, Sir Marc Isambard Brunel (1769-1849), was himself a famous engineer, of French parents. He eventually settled in Britain and married the Sophia Kingdom, an English woman whom he had known in France in earlier days. Their only son Isambard was born on 9 April 1806. He was sent to France at the age of 14 to study mathematics and science and was 16 when he returned to England to work with his father. Sir Marc was then building his famous tunnel under the River Thames. Isambard was recuperating near Bristol from injuries received in a tunnel cave-in when he became involved with his own first major project.

The Suspension Bridge ion the Avon Gorge

B The span of Brunel’s bridge was over 700ft, longer than any existing when it was designed, and the height above water about 245ft. The technical challenges of this engineering project were immense, and Brunel dealt with them with his usual, thoroughness and ingenuity. Two design competitions were held, and the great bridge designer Thomas Telford was the committee’s expert. Brunel presented four designs. He went beyond technicalities to include arguments based on, among other things, the grace of his tower design. Unfortunately, he only got so far as to put up the end piers in his lifetime. The Clifton Suspension Bridge was completed in his honor by his engineering friends in1864 and is still in use.

The Great Western Railway

C While Brunel was still in Bristol, and with the Avon Bridge project stopped or going slowly, he became aware that the civic authorities saw the need for a railway link to London. Railway location was controversial since private landowners and towns had to be dealt with. Mainly, the landed gentry did not want a messy, noisy railway anywhere near them. The Duke of Wellington (of Waterloo fame) was certainly against it. Again Brunel showed great skill in presenting his arguments to the various committees and individuals. BruneI built his railway with a broad gauge (7ft) instead of the standard 4ft 8½in, which had been used for lines already installed. There is no doubt that the broad gauge gave superior ride and stability, but it was fighting a standard.

Atmospheric railway:

D Brunel’s ready acceptance of new ideas overpowered good engineering judgment (at least in hindsight) when he advocated the installation of an atmospheric railway in South Devon. It had the great attraction of doing away with the locomotive and potentially could deal with steeper gradients. Since this connecting arm had to run along the slit, it had to be opened through a flap as the train progressed, but closed airtight behind it. Materials were not up to it, and this arrangement was troublesome and expensive to keep in repair. After a year of frustration, the system was abandoned. Brunel admitted his failure and took responsibility. He also took no fee for his work, setting a good professional example.

Brunel’s ships:

E The idea of using steam to power ships to cross the ocean appealed to Brunel. When his GWR company directors complained about the great length of their railway (it was only about 100 miles), Isambard jokingly suggested that they could even make it longer—why not go all the way to New York and call the link the Great Western. The “Great Western” was the first steamship to engage in transatlantic service. Brunel formed the Great Western Steamship Company and construction started on the ship in Bristol in 1836. Built of wood and 236ft long, the Great Western was launched in 1837 and powered by sail and paddlewheels. The first trip to New York took just 15 days, and 14 days to return. This was a great success, a one way trip under sail would take more than a month. The Great Western was the firsts steamship to engage in transatlantic service and made 74 crossings to New York.

F Having done so well with the Great Western, Brunel immediately got to work on an even bigger ship. Great Britain was made of iron and also built-in Bristol, 322ft in length. The initial design was for the ship to be driven by paddle wheels, but Brunel had seen one of the first propeller-driven ships to arrive in Britain, and he abandoned his plans for paddlewheel propulsion. The ship was launched in 1843 and was the first screw-driven iron ship to cross the Atlantic. Great Britain ran aground early in its career but was repaired, sold, and sailed for years to Australia, and other parts of the world, setting the standard for ocean travel. In the early 1970s, the old ship was rescued from the Falklands and is now under restoration in Bristol

G Conventional wisdom in Brunel’s day was that steamships could not carry enough coal to make long ocean voyages. But he correctly figured out that this was a case where size mattered. He set out to design the biggest ship ever, five times larger than any ship built up to that time. Big enough to carry fuel to get to Australia without refueling, in addition, it would carry 4,000 passengers.

The Great Eastern was 692ft long, with a displacement of about 32,000 tons. Construction began in 1854 on the Thames at Millwall. Brunel had chosen John Scott Russell to build the ship. He was a well-established engineer and naval architect, but the contract did not go well. Among other things, Scott Russell was very low in his estimates and money was soon a problem. Construction came to a standstill in 1856 and Brunel himself had to take over the work. But Brunel was nothing if not determined and by September 1859, after a delayed and problem -ridden launch, the Great Eastern was ready for the maiden voyage, Brunei was too sick to go, but it was just as well because only a few hours out there was an explosion in the engine room which would have destroyed a lesser ship. Brunel died within a week or so of the accident. The great ship never carried 4,000 passengers (among other things, the Suez Canal came along) and although it made several transatlantic crossings, it was not a financial success. Shortly after the Great Eastern began working life, the American entrepreneur Cyrus Field and his backers were looking for a ship big enough to carry 5,000 tons of telegraphic cable, which was to be laid on the ocean floor from Ireland to Newfoundland. Although Brunel did not have it in mind, the Great Eastern was an excellent vessel for this work on July 27, 1866. It successfully completed the connection and a hundred years of transatlantic communication by cable began. The ship continued this career for several years, used for laying cables in many parts of the world.

Movie of Metropolis

A When German director Fritz Lang visited the United States in 1924, his first glimpse of the country was a night-time view of the New York skyline from the deck of an ocean liner. This, he later recalled, was the direct inspiration for what is still probably the most innovative and influential science-fiction film ever made – Metropolis.

B Metropolis is a bleak vision of the early twenty-first century that is at once both chilling and exhilarating. This spectacular city of the future is a technological marvel of high-rise buildings connected by elevated railways and airships. It’s also a world of extreme inequality and social division. The workers live below ground and exist as machines working in an endless routine of mind-numbing 10-hour shifts while the city’s elite lead lives of luxury high above. Presiding over them all is the Master of Metropolis, John Fredersen, whose sole satisfaction seems to lie in the exercise of power.

C Lang’s graphic depiction of the future is conceived in almost totally abstract terms. The function of the individual machines is never defined. Instead, this mass of dials, levers and gauges symbolically stands for all machines and all industry, with the workers as slave-live extensions of the equipment they have to operate. Lang emphasizes this idea in the famous shift-change sequence at the start of the movie when the workers walk in zombie-like geometric ranks, all dressed in the same dark overalls and all exhibiting the same bowed head and dead-eyed stare. An extraordinary fantasy sequence sees one machine transformed into a huge open-jawed statue which then literally swallows them up.

D On one level the machines and the exploited workers simply provide the wealth and services which allow the elite to live their lives of leisure, but on a more profound level, the purpose of all this demented industry is to serve itself. Power, control and the continuance of the system from one 10-hour shift to the next is all that counts. The city consumes people and their labour and in the process becomes a perverse parody of a living being.

E It is enlightening, I think, to relate the film to the modern global economy in which multinational corporations now routinely close their factories in one continent so that they can take advantage of cheap labour in another. Like the industry in Metropolis, these corporations’ goals of increased efficiency and profits have little to do with the welfare of the majority of their employees or that of the population at large. Instead, their aims are to sustain the momentum of their own growth and to increase the monetary rewards to a tiny elite – their executives and shareholders. Fredersen himself is the essence of the big company boss: Rupert Murdoch would probably feel perfectly at home in his huge skyscraper office with its panoramic view of the city below. And it is important that there is never any mention of government in Metropolis – the whole concept is by implication obsolete. The only people who have power are the supreme industrialist, Fredersen, and his magician/scientist cohort Rotwang.

F So far so good: when the images are allowed to speak for themselves the film is impeccable both in its symbolism and in its cynicism. The problem with Metropolis is its sentimental story-line, which sees Freder, Fredersen’s son, instantly falling in love with the visionary Maria. Maria leads an underground pseudo-religious movement and preaches that the workers should not rebel but should await the arrival of a ‘Mediator’ between the ‘Head’ (capital) and the ‘Hands’ (labour). That mediator is the ‘Heart’ – love, as embodied, finally, by Freder’s love of Maria and his father’s love of him.

G Lang wrote the screenplay in collaboration with his then-wife Thea von Harbou. In 1933 he fled from the Nazis (and continued a very successful career in Hollywood). She stayed in Germany and continued to make films under the Hitler regime. There is a constant tension within the film between the too-tidy platitudes of von Harbou’s script and the uncompromisingly caustic vigour of Lang’s imagery.

H To my mind, both in Metropolis and in the real world, it’s not so much that the ‘Head’ and ‘Hands’ require a ‘Heart’ to mediate between them but that the ‘Hands’ need to develop their own ‘Head’, their own political consciousness, and act accordingly – through the ballot box, through buying power and through a sceptical resistance to the materialistic fantasies of the Fredersens.

I All the same, Metropolis is probably more accurate now as a representation of industrial and social relations than it has been at any time since its original release. And Fredersen is certainly still the most potent movie symbol of the handful of elusive corporate figureheads who increasingly treat the world as a Metropolis-like global village.

Internal and External Marketing

A Employees need to hear the same messages that you send out to the marketplace. At most companies, however, internal and external communications are often mismatched. This can be very confusing, and it threatens employees’ perceptions of the company’s integrity: They are told one thing by management but observe that a different message is being sent to the public. One health insurance company, for instance, advertised that the welfare of patients was the company’s number one priority, while employees were told that their main goal was to increase the value of their stock options through cost reductions. And one major financial services institution told customers that it was making a major shift in focus from being a financial retailer to a financial adviser, but, a year later, research showed that the customer experience with the company had not changed. It turned out that company leaders had not made an effort to sell the change internally, so employees were still churning out transactions and hadn’t changed their behavior to match their new adviser role.

B Enabling employees to deliver on customer expectations is important, of course, but it’s not the only reason a company needs to match internal and external messages. Another reason is to help push the company to achieve goals that might otherwise be out of reach. In 1997, when IBM launched its e-business campaign (which is widely credited for turning around the company’s image), it chose to ignore research that suggested consumers were unprepared to embrace IBM as a leader in e-business. Although to the outside world this looked like an external marketing effort, IBM was also using the campaign to align employees around the idea of the Internet as the future of technology. The internal campaign changed the way employees thought about everything they did, from how they named products to how they organized staff to how they approached selling. The campaign was successful largely because it gave employees a sense of direction and purpose, which in turn restored their confidence in IBM’s ability to predict the future and lead the technology industry. Today, research shows that people are four times more likely to associate the term “e-business” with IBM than with its nearest competitor, Microsoft.

C The type of “two-way branding” that IBM did so successfully strengthens both sides of the equation. Internal marketing becomes stronger because it can draw on the same “big idea” as advertising. Consumer marketing becomes stronger because the messages are developed based on employees’ behavior and attitudes, as well as on the company’s strengths and capabilities – indeed, the themes are drawn from the company’s very soul. This process can result in a more distinct advertising idea because marketers are more likely to create a message that’s unique to the company.

D Perhaps even more important, by taking employees into account, a company can avoid creating a message that doesn’t resonate with staff or, worse, one that builds resentment. In 1996, United Airlines shelved its “Come Fly the Friendly Skies” slogan when presented with a survey that revealed the depth of customer resentment toward the airline industry. In an effort to own up to the industry’s shortcomings, United launched a new campaign, “Rising,” in which it sought to differentiate itself by acknowledging poor service and promising incremental improvements such as better meals. While this was a logical premise for the campaign given the tenor of the times, a campaign focusing on customers’ distaste for flying was deeply discouraging to the staff. Employee resentment ultimately made it impossible for United to deliver the improvements it was promising, which in turn undermined the “Rising” pledge. Three years later, United decided employee opposition was undermining its success and pulled the campaign. It has since moved to a more inclusive brand message with the line “United,” which both audiences can embrace. Here, a fundamental principle of advertising – find and address a customer concern – failed United because it did not consider the internal market.

E When it comes to execution, the most common and effective way to link internal and external marketing campaigns is to create external advertising that targets both audiences. IBM used this tactic very effectively when it launched its e-business campaign. It took out an eight-page ad in the Wall Street Journal declaring its new vision, a message directed at both customers and internal stakeholders. This is an expensive way to capture attention, but if used sparingly, it is the most powerful form of communication; in fact, you need do it only once for everyone in the company to read it. There’s a symbolic advantage as well. Such a tactic signals that the company is taking its pledge very seriously; it also signals transparency – the same message going out to both audiences.

F Advertising isn’t the only way to link internal and external marketing. At Nike, a number of senior executives now hold the additional title of “Corporate Storyteller.” They deliberately avoid stories of financial successes and concentrate on parables of “just doing it,” reflecting and reinforcing the company’s ad campaigns. One tale, for example, recalls how legendary coach and Nike co-founder Bill Bowerman, in an effort to build a better shoe for his team, poured rubber into the family waffle iron, giving birth to the prototype of Nike’s famous Waffle Sole. By talking about such inventive moves, the company hopes to keep the spirit of innovation that characterizes its ad campaigns alive and well within the company.

G But while their messages must be aligned, companies must also keep external promises a little ahead of internal realities. Such promises provide incentives for employees and give them something to live up to. In the 1980s, Ford turned “Quality is Job!” from an internal rallying cry into a consumer slogan in response to the threat from cheaper, more reliable Japanese cars. It did so before the claim was fully justified, but by placing it in the public arena, it gave employees an incentive to match the Japanese. If the promise is pushed too far ahead, however, it loses credibility. When a beleaguered British Rail launched a campaign announcing service improvement under the banner “We’re Getting There,” it did so prematurely. By drawing attention to the gap between the promise and the reality, it prompted destructive press coverage. This, in turn, demoralized staff, who had been legitimately proud of the service advances they had made.

Paper or Computer?

A Computer technology was supposed to replace paper. But that hasn’t happened. Every country in the Western world uses more paper today, on a per- capita basis, than it did ten years ago. The consumption of uncoated free-sheet paper, for instance the most common kind of office paper — rose almost fifteen per cent in the United States between 1995 and 2000. This is generally taken as evidence of how hard it is to eradicate old, wasteful habits and of how stubbornly resistant we are to the efficiencies offered by computerization. A number of cognitive psychologists and ergonomics experts, however, don’t agree. Paper has persisted, they argue, for very good reasons: when it comes to performing certain kinds of cognitive tasks, paper has many advantages over computers. The dismay people feel at the sight of a messy desk — or the spectacle of air-traffic controllers tracking flights through notes scribbled on paper strips – arises from a fundamental confusion about the role that paper plays in our lives.

B The case for paper is made most eloquently in “The Myth of the Paperless Office”, by two social scientists, Abigail Sellen and Richard Harper. They begin their book with an account of a study they conducted at the International Monetary Fund, in Washington, D.C. Economists at the I.M.F. spend most of their time writing reports on complicated economic questions, work that would seem to be perfectly suited to sitting in front of a computer. Nonetheless, the I.M.F. is awash in paper, and Sellen and Harper wanted to find out why. Their answer is that the business of writing reports – at least at the I.M.F. is an intensely collaborative process, involving the professional judgments and contributions of many people. The economists bring drafts of reports to conference rooms, spread out the relevant pages, and negotiate changes with one other. They go back to their offices and jot down comments in the margin, taking advantage of the freedom offered by the informality of the handwritten note. Then they deliver the annotated draft to the author in person, taking him, page by page, through the suggested changes. At the end of the process, the author spreads out all the pages with comments on his desk and starts to enter them on the computer — moving the pages around as he works, organizing and reorganizing, saving and discarding.

C Without paper, this kind of collaborative and iterative work process would be much more difficult. According to Sellen and Harper, paper has a unique set of “affordances” — that is, qualities that permit specific kinds of uses. Paper is tangible: we can pick up a document, flip through it, read little bits here and there, and quickly get a sense of it. Paper is spatially flexible, meaning that we can spread it out and arrange it in the way that suits US best. And it’s tailorable: we can easily annotate it, and scribble on it as we read, without altering the original text. Digital documents, of course, have then own affordances. They can be easily searched, shared, stored, accessed remotely, and linked to other relevant material. But they lack the affordances that really matter to a group of people working together on a report. Sellen and Harper write:

D Paper enables a certain kind of thinking. Picture, for instance, the top of your desk. Chances are that you have a keyboard and a computer screen off to one side, and a clear space roughly eighteen inches square in front of your chair. What covers the rest of the desktop is probably piles- piles of papers, journals, magazines, binders, postcards, videotapes, and all the other artifacts of the knowledge economy. The piles look like a mess, but they aren’t. When a group at Apple Computer studied piling behavior several years ago, they found that even the most disorderly piles usually make perfect sense to the piler, and that office workers could hold forth in great detail about the precise history and meaning of their piles. The pile closest to the cleared, eighteen-inch-square working area, for example, generally represents the most urgent business, and within that pile the most important document of all is likely to be at the top. Piles are living, breathing archives. Over time, they get broken down and resorted, sometimes chronologically and sometimes thematically and sometimes chronologically and thematically; clues about certain documents may be physically embedded in the file by, say, stacking a certain piece of paper at an angle or inserting dividers into the stack.

E But why do we pile documents instead of filing them? Because piles represent the process of active, ongoing thinking. The psychologist Alison Kidd, whose research Sellen and Harper refer to extensively, argues that “knowledge workers” use the physical space of the desktop to hold “ideas which they cannot yet categorize or even decide how they might use.” The messy desk is not necessarily a sign of disorganization. It may be a sign of complexity: those who deal with many unresolved ideas simultaneously cannot sort and file the papers on their desks, because they haven’t yet sorted and filed the ideas in their head. Kidd writes that many of the people she talked to use the papers on their desks as contextual cues to’’ recover a complex set of threads without difficulty and delay” when they come in on a Monday morning, or after their work has been interrupted by a phone call. What we see when we look at the piles on our desks is, in a sense, the contents of our brains.

F This idea that paper facilitates a highly specialized cognitive and social process is a far cry from the way we have historically thought about the stuff. Paper first began to proliferate in the workplace in the late nineteenth century as part of the move toward “systematic management.” To cope with the complexity of the industrial economy, managers were instituting company-wide policies and demanding monthly, weekly, or even daily updates from their subordinates. Thus was born the monthly sales report, and the office manual and the internal company newsletter. The typewriter took off in the eighteen-eighties, making it possible to create documents in a fraction of the time it had previously taken, and that was followed closely by the advent of carbon paper, which meant that a typist could create ten copies of that document simultaneously. Paper was important not to facilitate creative collaboration and thought but as an instrument of control.

The secret of the Yawn

A When a scientist began to study yawning in the 1980s, it was difficult to convince some of his research students of the merits of “yawning science.” Although it may appear quirky, his decision to study yawning was a logical extension to human beings of my research in developmental neuroscience, reported in such papers as “Wing-flapping during Development and Evolution.” As a neurobehavioral problem, there is not much difference between the wing-flapping of birds and the face – and body-flapping of human yawners.

B Yawning is an ancient, primitive act. Humans do it even before they are born, opening wide in the womb. Some snakes unhinge their jaws to do it. One species of penguins yawns as part of mating. Only now are researchers beginning to understand why we yawn, when we yawn and why we yawn back. A professor of cognitive neuroscience at Drexel University in Philadelphia, Steven Platek, studies the act of contagious yawning, something done only by people and other primates.

C In his first experiment, he used a psychological test to rank people on their empathic feelings. He found that participants who did not score high on compassion did not yawn back. “We literally had people saying, ‘Why am I looking at people yawning?’” Professor Platek said. “It just had no effect.”

D For his second experiment, he put 10 students in a magnetic resonance imaging machine as they watched video tapes of people yawning. When the students watched the videos, the part of the brain which reacted was the part scientists believe controls empathy – the posterior cingulate, in the brain’s middle rear.” I don’t know if it’s necessarily that nice people yawn more, but I think it’s a good indicator of a state of mind,” said Professor Platek. “It’s also a good indicator if you’re empathizing with me and paying attention.”

E His third experiment is studying yawning in those with brain disorders, such as autism and schizophrenia, in which victims have difficulty connecting emotionally with others. A psychology professor at the University of Maryland, Robert Provine, is one of the few other researchers into yawning. He found the basic yawn lasts about six seconds and they come in bouts with an interval of about 68 seconds. Men and women yawn or half-yawn equally often, but men are significantly less likely to cover their mouths which may indicate complex distinction in genders.” A watched yawner never yawns,” Professor Provine said. However, the physical root of yawning remains a mystery. Some researchers say it’s coordinated within the hypothalamus of the brain, the area that also controls breathing.

F Yawning and stretching also share properties and may be performed together as parts of a global motor complex. But they do not always co-occur – people usually yawn when we stretch, but we don’t always stretch when we yawn, especially before bedtime. Studies by J.I.P, G.H.A. Visser and H.F. Prechtl in the early 1980s, charting movement in the developing fetus using ultrasound, observed not just yawning but a link between yawning and stretching as early as the end of the first prenatal trimester.

G The most extraordinary demonstration of the yawn-stretch linkage occurs in many people paralyzed on one side of their body because of brain damage caused by a stroke. The prominent British neurologist Sir Francis Walshe noted in 1923 what when these hemiplegics yawn, they are startled and mystified to observe that their otherwise paralyzed arm rises and flexes automatically in what neurologists term an “associated response.” Yawning apparently activates undamaged, unconsciously controlled connections between the brain and the cord motor system innervating the paralyzed limb. It is not known whether the associated response is a positive prognosis for recovery, nor whether yawning is therapeutic for reinnervation or prevention of muscular atrophy.

H Clinical neurology offers other surprises. Some patients with “locked-in” syndrome, who are almost totally deprived of the ability to move voluntarily, can yawn normally. The neural circuits for spontaneous yawning must exist in the brain stem near other respiratory and vasomotor centers, because yawning is performed by anencephalic who possess only the medulla oblongata. The multiplicity of stimuli of contagious yawning, by contrast, implicates many higher brain regions.

Sand Dunes

A One of the main problems posed by sand dunes is their encroachment on human habitats. Sand dunes move by different means, all of them aided by the wind. Sand dunes threaten buildings and crops in Africa, the Middle East, and China. Preventing sand dunes from overwhelming cities and agricultural areas has become a priority for the United Nations Environment Program. On the other hand, dune habitats provide niches for highly specialized plants and animals, including numerous rare and endangered species.

B Sand is usually composed of hard minerals such as quartz that cannot be broken down into silt or clay. Yellow, brown and reddish shades of sand indicate their presence of iron compounds. Red sand is composed of quartz coated by a layer of iron oxide. White sands are nearly pure gypsum. Sand with a high percentage of silicate can be used in glassmaking. Sandstone is created by sand, mixed with lime, chalk or some other material that acts as a binding agent, that is deposited in layers at the bottom of a sea or other area and pressed together into rock by the great pressure of sediments that are deposited on top of it over thousands or millions of years.

C The most common dune form on Earth and on Mars is crescentic. Crescent-shaped mounds are generally wider than they are long. The slipfaces are on the concave sides of the dunes. These dunes form under winds that blow consistently from one direction, and they also are known as barchans or transverse dunes. Some types of crescentic dunes move more quickly over desert surfaces than any other type of dune. A group of dunes moved more than 100 metres per year between 1954 and 1959 the China’s Ningxia Province, and similar speeds have been recorded in the Western Desert of Egypt. The largest crescentic dunes on Earth, with mean crest-to-crest widths of more than 3 kilometres, are in China’s Taklamakan Desert.

D Radially symmetrical, star dunes are pyramidal sand mounds with slipfaces on there or more arms that radiate from the high center of the mound. They tend to accumulate in areas with multidirectional wind regimes. Star dunes grow upward rather than laterally. They dominate the Grand Erg Oriental of the Sahara. In other deserts, they occur around the margins of the sand seas, particularly near topographic barriers. In the southeast Badain Jaran Desert of China, the star dunes are up to 500 metres tall and may be the tallest dunes on Earth. Straight or slightly sinuous sand ridges typically much longer than they are wide are known as linear dunes. They may be more than 160 kilometres (99 mi) long. Some linear dunes merge to form Y-shaped compound dunes. Many forms in bidirectional wind regimes. The long axes of these dunes extend in the resultant direction of sand movement. Linear loess hills known as pahas are superficially similar.

E Once sand begins to pile up, ripples and dunes can form. Wind continues to move sand up to the top of the pile until the pile is so steep that it collapses under its own weight. The collapsing sand comes to rest when it reaches just the right steepness to keep the dune stable. This angle, usually about 30-34°, is called the angle of repose. Every pile of loose particles has a unique angle of repose, depending upon the properties of the material it’s made of, such as the grain size and roundness. Ripples grow into dunes with the increase of wind and sand input.

F The repeating cycle of sand inching up the windward side to the dune crest, then slipping down the dune’s slip face allows the dune to inch forward, migrating in the direction the wind blows. As you might guess, all of this climbing then slipping leaves its mark on the internal structure of the dune. The image on the right shows fossil sand dune structure preserved in the Merced Formation at Fort Funston, Golden Gate National Recreation Area. The sloping lines or laminations you see are the preserved slip faces of a migrating sand dune. This structure is called cross-bedding and can be the result of either wind or water currents. The larger the cross-bedded structure, however, the more likely it is to be formed by wind, rather than water.

G Sand dunes can “sing” at a level up to 115 decibels and generate sounds in different notes. The dunes at Sand Mountain n Nevada usually sing in a low C but can also sing in B and C sharp. The La Mar de Dunas in Chile hum in F while those at the Ghord Lahmar in Morocco howl in G sharp. The sounds are produced by avalanches of sand generated by blowing winds. For a while, it was thought that the avalanches caused the entire dune to resonate like a flute or violin but if that were true then different size dunes would produce different notes. In the mid 2000s, American, French and Moroccan scientists visiting sand dunes in Morocco, Chile, China and Oman published a paper in the Physical Review Letters that determined the sounds were produced by collisions between grains of sand that caused the motions of the grains to become synchronized, causing the outer layer of a dune to vibrate like the cone of a loudspeaker, producing sound. The tone of the sounds depended primarily on the size of the grains.

H Scientists performed a computer simulation on patterns and dynamics of desert dunes in laboratory. Dune patterns observed in deserts were reproduced. From the initial random state, stars and linear dunes are produced, depending on the variability of the wind direction. The efficiency in sand transport is calculated through the course of development. Scientists found that the sand transport is the most efficient in the linear transverse dune. The efficiency in sand transport always increased through the evolution, and the way it increases was stepwise. They also found that the shadow zone, the region where the sand wastes the chance to move, shrinks through the course of evolution, which greatly helps them build a model to simulate a sand move.

Decision making and Happiness

A Americans today choose among more options in more parts of life than has ever been pos­sible before. To an extent, the opportunity to choose enhances our lives. It is only logical to think that if some choices are good, more is better; people who care about having infinite options will benefit from them, and those who do not can always just ignore the 273 versions of cereal they have never tried. Yet recent research strongly suggests that, psychologically, this assumption is wrong, with 5% lower percentage announcing they are happy. Although some choices are undoubtedly better than none, more is not always better than less.

B Recent research offers insight into why many people end up unhappy rather than pleased when their options expand. We began by making a distinction between “maximizers” (those who always aim to make the best possible choice) and “satisficers” (those who aim for “good enough,” whether or not better selections might be out there).

C In particular, we composed a set of statements—the Maximization Scale—to diagnose peo­ple’s propensity to maximize. Then we had several thousand people rate themselves from 1 to 7 (from “completely disagree” to “completely agree”) on such statements as “I never settle for second best.” We also evaluated their sense of satisfaction with their decisions. We did not define a sharp cutoff to separate maximizers from satisficers, but in general, we think of individuals whose average scores are higher than 4 (the scale’s midpoint) as maxi- misers and those whose scores are lower than the midpoint as satisficers. People who score highest on the test—the greatest maximizers—engage in more product comparisons than the lowest scorers, both before and after they make purchasing decisions, and they take longer to decide what to buy. When satisficers find an item that meets their standards, they stop looking. But maximizers exert enormous effort reading labels, checking out consumer magazines and trying new products. They also spend more time comparing their purchas­ing decisions with those of others.

D We found that the greatest maximizers are the least happy with the fruits of their efforts. When they compare themselves with others, they get little pleasure from finding out that they did better and substantial dissatisfaction from finding out that they did worse. They are more prone to experiencing regret after a purchase, and if their acquisition disappoints them, their sense of well-being takes longer to recover. They also tend to brood or ruminate more than satisficers do.

E Does it follow that maximizers are less happy in general than satisficers? We tested this by having people fill out a variety of questionnaires known to be reliable indicators of well­being. As might be expected, individuals with high maximization scores experienced less satisfaction with life and were less happy, less optimistic and more depressed than people with low maximization scores. Indeed, those with extreme maximization ratings had depression scores that placed them in the borderline of clinical range.

F Several factors explain why more choice is not always better than less, especially for maxi­misers. High among these are “opportunity costs.” The quality of any given option cannot be assessed in isolation from its alternatives. One of the “costs” of making a selection is losing the opportunities that a different option would have afforded. Thus, an opportunity cost of vacationing on the beach in Cape Cod might be missing the fabulous restaurants in the Napa Valley. Early Decision Making Research by Daniel Kahneman and Amos Tversky showed that people respond much more strongly to losses than gains. If we assume that opportunity costs reduce the overall desirability of the most preferred choice, then the more alternatives there are, the deeper our sense of loss will be and the less satisfaction we will derive from our ultimate decision.

G The problem of opportunity costs will be better for a satisficer. The latter’s “good enough” philosophy can survive thoughts about opportunity costs. In addition, the “good enough” standard leads to much less searching and inspection of alternatives than the maximizer’s “best” standard. With fewer choices under consideration, a person will have fewer opportu­nity costs to subtract.

H Just as people feel sorrow about the opportunities they have forgone, they may also suffer regret about the option they settled on. My colleagues and I devised a scale to measure proneness to feeling regret, and we found that people with high sensitivity to regret are less happy, less satisfied with life, less optimistic and more depressed than those with low sensitivity. Not surprisingly, we also found that people with high regret sensitivity tend to be maximizers. Indeed, we think that worry over future regret is a major reason that individuals become maximizers. The only way to be sure you will not regret a decision is by making the best possible one. Unfortunately, the more options you have and the more opportunity costs you incur, the more likely you are to experience regret.

I In a classic demonstration of the power of sunk costs, people were offered season subscrip­tions to a local theatre company. Some were offered the tickets at full price and others at a discount. Then the researchers simply kept track of how often the ticket purchasers actu­ally attended the plays over the course of the season. Full-price payers were more likely to show up at performances than discount payers. The reason for this, the investigators argued, was that the full-price payers would experience more regret if they did not use the tickets because not using the more costly tickets would constitute a bigger loss. To increase sense of happiness, we can decide to restrict our options when the decision is not crucial. For example, make a rule to visit no more than two stores when shopping for clothing.

The history of the guitar

The word ‘guitar’ was brought into English as an adaptation of the Spanish word ‘guitarra’, which was, in turn, derived from the Greek ‘kithara’. Tracing the roots of the word further back into linguistic history, it seems to have been a combination of the Indo-European stem ‘guit-‘, meaning music, and the root ’-tar’, meaning chord or string. The root ‘-tar’ is actually common to a number of languages, and can also be found in the word ’sitar’, also a stringed musical instrument. Although the spelling and pronunciation differ between languages, these key elements have been present in most words for ‘guitar’ throughout history.

While the guitar may have gained most of its popularity as a musical instrument during the modern era, guitar-like instruments have been in existence in numerous cultures throughout the world for more than 5,000 years. The earliest instruments that the modern eye and ear would recognise as a ‘normal’ acoustic guitar date from about 500 years ago. Prior to this time, stringed instruments were in use throughout the world, but these early instruments are known primarily from visual depictions, not from the continued existence of music written for them. The majority of these depictions show simple stringed instruments, often lacking some of the parts that define a modern guitar. A number of these instruments have more in common with the lute than the guitar.

There is some uncertainty about the exact date of the earliest six-string guitar. The oldest one still in existence, which was made by Gaetano Vinaccia, is dated 1779. However, the authenticity of six-string guitars alleged to have been made prior to 1790 is often suspect, as many fakes have been discovered dating to this era. The early nineteenth century is generally accepted as the time period during which six-string guitars began taking on their modern shape and dimensions. Thus for nearly two hundred years, luthiers, or guitar makers, have been producing versions of the modern acoustic guitar.

The first electric guitar was not developed until the early twentieth century. George Beauchamp received the first patent for an electric guitar in 1936, and Beauchamp went on to co-found Rickenbacker, originally known as the Electro String Instrument Company. Although Rickenbacker began producing electric guitars in the late 1930s, this brand received most of its fame in the 1960s, when John Lennon used a Rickenbacker guitar for the Beatles’ debut performance on the Ed Sullivan show in 1964. George Harrison later bought a Rickenbacker guitar of his own, and the company later gave him one of their earliest 12-string electric guitars. Paul McCartney also used a Rickenbacker bass guitar for recording. The Beatles continued to use Rickenbacker guitars throughout their career, and made the instruments highly popular among other musicians of the era.

The Fender Musical Instruments Company and the Gibson Guitar Corporation were two other early electric guitar pioneers, both developing models in the early 1950s. Fender began with the Telecaster in 1950 and 1951, and the Fender Stratocaster debuted in 1954. Gibson began selling the Gibson Les Paul, based partially on assistance from jazz musician and guitar innovator Les Paul, in 1952. The majority of present day solid-body electric guitars are still based largely on these three early electric guitar designs.

Throughout the history of the guitar, an enormous number of individuals have made their mark on the way in which the instrument was built, played and perceived. Though some of these individuals are particularly well known, like the Beatles or Les Paul, the majority of these people are virtually invisible to most modern guitar fans. By looking at the entire history of the guitar, rather than just recent developments, largely confined to electric guitars, it is possible to see more of the contributions of earlier generations.

Volatility Kills

A Despite gun battles in the capital of Chad, rioting in Kenya, and Galloping inflation in Zimbabwe, the economies of sub-Saharan Africa are, as a whole, in better shape than they were a few years ago. The World Bank has reported recently that this part of the continent experienced a respectable growth rate of 5.6 percent in 2006 and a higher rate from 1995 to 2005 than in previous decades. The bank has given a cautions assessment that the region may have reached a turning point. An overriding question for developmental economists remains whether the upswing will continue so Africans can grow their way out of poverty that relegates some 40 percent of the nearly 744 million in that region to living on less than a dollar a day. The optimism, when inspected more closely, maybe short-lived because of the persistence of a devastating pattern of economic volatility that has lingered for decades.

B “In reality, African countries grow as fast as Asian countries and other developing countries during the good times, but afterward they see growth collapses,” comments Jorge Arbache, a senior World Bank economist. “How to prevent collapses may be as important as promoting growth.” If these collapses had not occurred, he observes, the level of gross domestic product for each citizen of the 48 nations of sub -Saharan Africa would have been third higher.

C the prerequisites to prevent the next crash are not in place, according to a World Bank study issued in January, Is Africa’s Recent Growth Robust? The growth period that began in 1995, driven by a commodities boom spurred in particular by demand from China, may not be sustainable, because the economic fundamentals- new investment and the ability to stave off inflation, among other factors-are absent. The region lacks the necessary infrastructure that would encourage investors to look to Africa to find the next Bengaluru ( Bangalore ) or Shenzhen, a November report from the bank concludes. For sub–Saharan countries rich in oil and other resources, a boom period may even undermine efforts to institute sound economic practices.. From 1996 to 2005, with growth accelerating, measures of governance– factors such as political stability, rule of law, and control of corruption- actually worsened, especially for countries endowed with abundant mineral resources, the January report notes.

D Perhaps the most incisive analysis of the volatility question comes from Paul Collier, a longtime specialist in African economics at the University of Oxford and author of the recent book The Bottom Billion. He advocates a range of options that the U.S. and other nations could adopt when formulating policy toward African countries. They include revamped trade measures, better-apportioned aid, and sustained military intervention in certain instances, to avert what he sees as a rapidly accelerating divergence of the world’s poorest, primarily in Africa, from the rest of the world, even other developing nations such India and China.

E Collier finds that bad governance is the main reason countries fail to take advantage of the revenue bonanza that results from a boom. moreover, a democratic government, he adds, often makes the aftermath of a boom worse. “Instead of democracy disciplining governments to manage these resource booms well, what happens is that the resource revenues corrupt the normal functioning of democracy-unless you stop ( them from) corrupting the normal function of democracy with sufficient checks and balances”, he said at a talk ion January at the Carnegie Council in New York City.

F Collier advocates that African nations institute an array of standards and codes to bolster governments, one of which would substitute auctions for bribes in apportioning mineral rights and another of which would tax export revenues adequately. He cites the Democratic Republic of the Congo, which took in $ 200 million from mineral exports in 2006 yet collected only $86000 in royalties for its treasury. “If a nation gets these points right, ” he argues, “It’s going to develop. If it gets them wrong, it won’t.”

G To encourage reform, Collier recommends that the G8 nations agree to accept these measures as voluntary guidelines for multinationals doing business in Africa- companies, for instance, would only enter new contracts through auctions monitored by an international verification group. Such an agreement would follow the examples of the so-called Kimberley Process, which has effectively undercut the trade in blood diamonds, and the Extractive Industries Transparency Initiative, in which a government must report to its citizens the revenues it receives from sales of natural resources.

H These measures, he says, are more important than elevating aid levels, an approach emphasized by economist Jeffrey D. Sachs of Columbia University and celebrity activists such as Bono. Collier insists that first Angola receives tens of billions of dollars in oil revenue and whether it gets a few hundred million more or less in aid is really second-order.

The sense of flavour

A Scientists now believe that human beings acquired the sense of taste as a way to avoid being poisoned. Edible plants generally taste sweet; deadly ones, bitter. Taste is supposed to help us differentiate food that’s good for us from food that’s not. The taste buds on our tongues can detect the presence of half a dozen or so basic tastes, including sweet, sour, bitter, salty, and umami (a taste discovered by Japanese researchers, a rich and full sense of deliciousness triggered by amino acids in foods such as shellfish, mushrooms, potatoes, and seaweed). Tastebuds offers a limited means of detection, however, compared with the human olfactory system, which can perceive thousands of different chemical aromas. Indeed, ‘flavor’ is primarily the smell of gases being released by the chemicals you’ve just put in your mouth. The aroma of food can be responsible for as much as 90% of its flavor.

B The act of drinking, sucking or chewing a substance releases its volatile gases. They flow out of the mouth and up the nostrils, or up the passageway at the back of the mouth, to a thin layer of nerve cells called the olfactory epithelium, located at the base of the nose, right between the eyes. The brain combines the complex smell signals from the epithelium with the simple taste signals from the tongue, assigns a flavor to what’s in your mouth, and decides if it’s something you want to eat.

C Babies like sweet tastes and reject bitter ones; we know this because scientists have rubbed various flavors inside the mouths of infants and then recorded their facial reactions. A person’s food preferences, like his or her personality, are formed during the first few years of life, through a process of socialization. Toddlers can learn to enjoy hot and spicy food, bland health food, or fast food, depending upon what the people around them eat. The human sense of smell is still not fully understood. It is greatly affected by psychological factors and expectations. The mind filters out the overwhelming majority of chemical aromas that surround us, focusing intently on some, ignoring others. People can grow accustomed to bad smells or good smells; they stop noticing what once seemed overpowering.

D Aroma and memory are somehow inextricably linked. A smell can suddenly evoke a long-forgotten moment. The flavours of childhood foods seem to leave an indelible mark, and adults often return to them, without always knowing why. These ‘comfort foods’ become a source of pleasure and reassurance a fact that fast-food chains work hard to promote Childhood memories of Happy Meals can translate into frequent adult visits to McDonald’s’, like those of the chain’s ‘heavy users’, the customers who eat there four or five times a week.

E The human craving for flavour has been a large unacknowledged and unexamined force in history. Royal empires have been built, unexplored lands have been traversed, great religions and philosophies have been forever changed by the spice trade. In 1492, Christopher Columbus set sail in order to try to find new seasonings and thus to make his fortune with this most desired commodity of that time. Today, the influence of flavour in the world marketplace is no less decisive. The rise and fall of corporate empires – soft-drink companies, snack-food companies, and fast-food chains – is frequently determined by how their products taste.

F The flavor industry emerged in the mid-1800s, as processed foods began to be manufactured on a large scale. Recognizing the need for flavor additives, the early food processors turned to perfume companies that had years of experience working with essential oils and volatile aromas. The great perfume houses of England, France, and the Netherlands produced many of the first flavor compounds. In the early part of the 20th century, Germany’s powerful chemical industry assumed the lead in flavour production. Legend has it that a German scientist discovered methyl anthranilate, one of the first artificial flavours, by accident while mixing chemicals in his laboratory. Suddenly, the lab was filled with the sweet smell of grapes. Methyl anthranilate later became the chief flavoring compound of manufactured grape juice.

G The quality that people seek most of all in a food, its flavour, is usually present in a quantity too infinitesimal to be measured by any traditional culinary terms such as ounces or teaspoons. Today’s sophisticated spectrometers, gas chromatograph, and headspace vapor analyzers provide a detailed map of a food’s flavour components, detecting chemical aromas in amounts as low as one part per billion. The human nose, however, is still more sensitive than any machine yet invented. A nose can detect aromas present in quantities of a few parts per trillion. Complex aromas, such as those of coffee or roasted meat, may be composed of gases from nearly a thousand different chemicals. The chemical that provides the dominant flavour of bell pepper can be tasted in amounts as low as 0.02 parts per billion; one drop is sufficient to add flavour to the amount of water needed to fill five average-sized swimming pools.

Digital diet

A Telecommuting, Internet shopping and online meetings may save energy as compared with in-person alternatives, but as the digital age moves on, its green reputation is turning a lot browner. E-mailing, number crunching and Web searches in the U.S. consumed as much as 61 billion kilowatt-hours last year, or 1.5 per cent of the nation’s electricity-half of which comes from coal. In 2005 the computers of the world ate up 123 billion kilowatt-hours of energy, a number that will double by 2010 if present trends continue, according to Jonathan Koomey, a staff scientist at Lawrence Berkeley National Laboratory. As a result, the power bill to run a computer over its lifetime will surpass the cost of buying the machine in the first place giving Internet and computer companies a business reason to cut energy costs, as well as an environmental one.

B One of the biggest energy sinks comes not from the computers themselves but from the air-conditioning needed to keep them from overheating. For every kilowatt-hour of energy used for computing in a data centre, another kilowatt-hour is required to cool the furnace-like racks of servers.

C For Internet giant Google, this reality has driven efforts such as the installation of a solar array that can provide 30 per cent of the peak power needs of its Mountain View, Calif., headquarters as well as increased purchases of renewable energy. But to deliver Web pages within seconds, the firm must maintain hundreds of thousands of computer servers in cavernous buildings. “It’s a good thing to worry about server energy efficiency,” remarks Google’s green energy czar Bill Weihl. “We are actively working to maximize the efficiency of our data centres, which account for most of the energy Google consumes worldwide.” Google will funnel some of its profits into a new effort, dubbed RE

D In the meantime, the industry as a whole has employed a few tricks to save watts. Efforts include cutting down on the number of transformations the electricity itself must undergo before achieving the correct operating voltage; rearranging the stacks of servers and the mechanics of their cooling; and using software to create multiple “virtual” computers, rather than having to deploy several real ones. Such virtualization has allowed computer maker Hewlett-Packard to consolidate 86 data centers spread throughout the world to just three, with three backups, says Pat Tiernan, the firm’s vice president of social and environmental responsibility.

E The industry is also tackling the energy issue at the computer-chip level. With every doubling of processing power in recent years has come a doubling in power consumption. But to save energy, chipmakers such as Intel and AMD have shifted to so-called multicore technology, which packs multiple processors into one circuit rather than separating them. “When we moved to multicore-away from a linear focus on megahertz and gigahertz—and throttled down microprocessors, the energy savings were pretty substantial,” says Allyson Klein, Intel’s marketing manager for its Ecotech Initiative. Chipmakers continue to shrink circuits on the nanoscale as well, which means a chip needs less electricity” to deliver the same performance, she adds.

F With such chips, more personal computers will meet various efficiency standards, such as Energy Star compliance (which mandates that a desktop consume no more than 65 watts). The federal government, led by agencies such as NASA and the Department of Defense may soon require all their purchases to meet the Electronic Product Environmental Assessment Tool standard. And Google, Intel and others have formed the Climate Savers Computing Initiative, an effort to cut power consumption from all computers by 50 per cent by 2010.

G Sleep modes and other power management tools built into most operating systems can offer savings today. Yet about 90 per cent of computers do not have such settings enabled, according to Klein. Properly activated, they would prevent a computer from leading to the emission of thousands of kilograms of carbon dioxide from power plants every year. But if powering down or unplugging the computer (the only way it uses zero power) is not an option, then perhaps the most environmentally friendly use of all those wasted computing cycles is in helping to model climate change. The University of Oxford’s ClimatePrediction.net offers an opportunity to at least predict the consequences of all that coal burning.

H CO2 Stats is a free tool that can be embedded into any Website to calculate the carbon dioxide emissions associated with using it. That estimate is based on an assumption of 300 watts of power consumed by the personal computer, network and server involved- or 16.5 milligrams of CO2 emitted every second of use. “The typical carbon footprint is roughly equivalent to 1.5 people breathing,” says physicist Alexander Wissner-Gross of Harvard University, who co-created the Web tool.

Intelligence and Giftedness

A In 1904 the French minister of education, facing limited resources for schooling, sought a way to separate the unable from the merely lazy. Alfred Binet got the job of devising selection principles and his brilliant solution put a stamp on the study of intelligence and was the forerunner of intelligence tests still used today, he developed a thirty-problem test in 1905, which tapped several abilities related to intellect, such as judgment and reasoning, the test determined a given child’s mental age’. The test previously established a norm for children of a given physical age. (for example, five-year-old on average get ten items correct), therefore, a child with a mental age of five should score 10, which would mean that he or she was functioning pretty much as others of that age. The child’s mental age was then compared to his physical age.

B A large disparity in the wrong direction (e.g., a child of nine with a mental age of four) might suggest inability rather than laziness and mean he or she was earmarked for special schooling, Binet, however, denied that the test was measuring intelligence, its purpose was simply diagnostic, for selection only. This message was however lost and caused many problems and misunderstanding later.

C Although Binet’s test was popular, it was a bit inconvenient to deal with a variety of physical and mental ages. So in 1912, Wilhelm Stern suggested simplifying this by reducing the two to a single number, he divided the mental age by the physical age and multiplied the result by 100. An average child, irrespective of age, would score 100. A number much lower than 100 would suggest the need for help, and one much higher would suggest a child well ahead of his peer.

D This measurement is what is now termed the IQ (for intelligence quotient) score and it has evolved to be used to show how a person, adult or child, performed in relation to others. (the term IQ was coined by Lewis M. Terman, professor of psychology and education of Stanford University, in 1916. He had constructed an enormously influential revision of Binet’s test, called the Stanford-Binet test, versions of which are still given extensively.)

E The field studying intelligence and developing tests eventually coalesced into a sub-field of psychology called psychometrics (psycho for ‘mind’ and metrics for ‘measurements’). The practical side of psychometrics (the development and use of tests) became widespread quite early, by 1917, when Einstein published his grand theory of relativity, mass-scale testing was already in use. Germany’s unrestricted submarine warfare (which led to the sinking of the Lusitania in 1915) provoked the United States to finally enter the First World War in the same year. The military had to build up an army very quickly; it had two million inductees to sort out. Who would become officers and who enlisted men? Psychometricians developed two intelligence tests that help sort all these people out, at least to some extent, this was the first major use of testing to decide who lived and who died, as officers were a lot safer on the battlefield, the tests themselves were given under horrendously bad conditions, and the examiners seemed to lack common sense, a lot of recruits simply had no idea what to do and in several sessions most inductees scored zero! The examiners also came up with the quite astounding conclusion from the testing that the average American adult’s intelligence was equal to that of a thirteen-year-old!

F Intelligence testing enforced political and social prejudice, their results were used to argue that Jews ought to be kept out of the united states because they were so intelligently inferior that they would pollute the racial mix, and blacks ought not to be allowed to breed at all. And so abuse and test bias controversies continued to plaque psychometrics.

G Measurement is fundamental to science and technology, science often advances in leaps and bounds when measurement devices improve, psychometrics has long tried to develop ways to gauge psychological qualities such as intelligence and more specific abilities, anxiety, extroversion, emotional stability, compatibility, with a marriage partner, and so on. Their scores are often given enormous weight, a single IQ measurement can take on a life of its own if teachers and parents see it as definitive, it became a major issue in the 70s, when court cases were launched to stop anyone from making important decisions based on IQ test scores, the main criticism was and still is that current tests don’t really measure intelligence, whether intelligence can be measured at all is still controversial, some say it cannot others say that IQ tests are psychology’s greatest accomplishments.

Museum Blockbuster

A Since the 1980s, the term “blockbuster” has become the fashionable word for the special spectacular museum, art gallery or science centre exhibitions. These exhibitions have the ability to attract large crowds and often large corporate sponsors. Here is one of some existing definitions of a blockbuster: Put by Elsen (1984), a blockbuster is a “… large scale loan exhibition that people who normally don’t go to museums will stand in line for hours to see …” James Rosenfield, writing in Direct Marketing in 1993, has described a successful blockbuster exhibition as a “… triumph of both curatorial and marketing skills …” My own definition for a blockbuster is “a popular, high profile exhibition on display for a limited period, that attracts the general public, who are prepared to both stand in line and pay a fee in order to partake in the exhibition.” What both Elsen and Rosenfield omit in their descriptions of a blockbuster, is that people are prepared to pay a fee to see a blockbuster and that the term blockbuster can just as easily apply to a movie or a museum exhibition.

B Merely naming an exhibition or movie a blockbuster, however, does not make it a blockbuster. The term can only apply when the item in question has had an overwhelmingly successful response from the public. However, in literature from both the UK and USA the other words that also start to appear in descriptions of a blockbuster are “less scholarly”, “non-elitist” and “popularist”. Detractors argue that blockbusters are designed to appeal to the lowest common denominator, while others extol the virtues of encouraging scholars to cooperate on projects and to provide exhibitions that cater for a broad selection of the community rather than an elite sector.

C Maintaining and increasing visitor levels is paramount in the new museology. This requires continued product development. Not only the creation or hiring of blockbuster exhibitions but regular exhibition changes and innovations. In addition, the visiting public has become customers rather than visitors, and the skills that are valued in museums, science centres and galleries to keep the new customers coming through the door have changed. High on the list of requirements are commercial, business, marketing and entrepreneurial skills. Curators are now administrators. Being a director of an art gallery no longer requires an Arts Degree. As succinctly summarised in the Economist in 1994 “business nous and public relation skills” were essential requirements for a director, and the ability to compete with other museums to stage travelling exhibitions which draw huge crowds.

D The new museology has resulted in the convergence of museums, the heritage industry, and tourism, profit-making and pleasure-giving. This has given rise to much debate about the appropriateness of adopting the activities of institutions so that they more closely reflect the priorities of the market place and whether it is appropriate to see museums primarily as tourist attractions. At many institutions, you can now hold office functions in the display areas, or have dinner with the dinosaurs. Whatever commentators may think, managers of museums, art galleries and science centres worldwide are looking for artful ways to blend culture and commerce, and blockbuster exhibitions are at the top of the list. But while blockbusters are all part of the new museology, there is proof that you don’t need a museum, science centre or art gallery to benefit from the drawing power of a blockbuster or to stage a blockbuster.

E But do blockbusters held in public institutions really create a surplus to fund other activities? If the bottom line is profit, then according to the accounting records of many major museums and galleries, blockbusters do make money. For some museums overseas, it may be the money that they need to update parts of their collections or to repair buildings that are in need of attention. For others in Australia, it may be the opportunity to illustrate that they are attempting to pay their way, by recovering part of their operating costs or funding other operating activities with off-budget revenue. This makes the economic rationalists cheerful. However, not all exhibitions that are hailed to be blockbusters will be blockbusters, and some will not make money. It is also unlikely that the accounting systems of most institutions will recognise the real cost of either creating or hiring a blockbuster.

F Blockbusters require large capital expenditure, and draw on resources across all branches of an organisation; however, the costs don’t end there. There is a Human Resource Management cost in addition to a measurable ‘real’ dollar cost. Receiving a touring exhibition involves large expenditure as well, and draws resources from across functional management structures in project management style. everyone from a general labourer to a building servicing unit, the front of the house, technical, promotion, education and administration staff, are required to perform additional tasks. Furthermore, as an increasing number of institutions in Australia try their hand at increasing visitor numbers, memberships (and therefore revenue), by staging blockbuster exhibitions, it may be less likely that blockbusters will continue to provide a surplus to subsidise other activities due to the competitive nature of the market. There are only so many consumer dollars to go around, and visitors will need to choose between blockbuster products.

G Unfortunately, when the bottom-line is the most important objective to the mounting of blockbuster exhibitions, this same objective can be hard to maintain. Creating, mounting or hiring blockbusters is exhausting for staff, with the real costs throughout an institution difficult to calculate. Although the direct aims may be financial, creating or hiring a blockbuster has many positive spin-offs; by raising their profile through a popular blockbuster exhibition, a museum will be seen in a more favorable light at budget time. Blockbusters mean crowds, and crowds are good for the local economy, providing increased employment for shops, hotels, restaurants, the transport industry and retailers. Blockbusters expose staff to the vagaries and pressures of the market place and may lead to creative excellence. Either the success or failure of a blockbuster may highlight the need for managers and policymakers to rethink their strategies. However, the new museology and the apparent trend towards blockbusters make it likely that museums, art galleries and particularly science centres will be seen as part of the entertainment and tourism industry, rather than as cultural icons deserving of government and philanthropic support.

H Perhaps the best pathway to take is one that balances both blockbusters and regular exhibitions. However, this easy middle ground may only work if you have enough space, and have alternate sources of funding to continue to support the regular less exciting fare. Perhaps the advice should be to make sure that your regular activities and exhibitions are more enticing, and find out what your local community wants from you. The question (trend) now at most museums and science centres, is “What blockbusters can we tour to overseas venues and will it be cost-effective?”

Beyond the blue line

A Much of the thrill of venturing to the far side of the world rests on the romance of difference. So one feels a certain sympathy for Captain James Cook on the day in 1778 that he “discovered” Hawaii. Then on his third expedition to the Pacific, the British navigator had explored scores of islands across the breadth of the sea, from lush New Zealand to the lonely wastes of Easter Island. This latest voyage had taken him thousands of miles north from the Society Islands to an archipelago so remote that even the old Polynesians back on Tahiti knew nothing about it. Imagine Cook’s surprise, then, when the natives of Hawaii came paddling out in their canoes and greeted him in a familiar tongue, one he had heard on virtually every mote of inhabited land he had visited. Marveling at the ubiquity of this Pacific language and culture, he later wondered in his journal: “How shall we account for this Nation spreading itself so far over this vast ocean?”

B That question, and others that flow from it has tantalized inquiring minds for centuries: Who were these amazing seafarers? Where did they come from, starting more than 3,000 years ago? And how could a Neolithic people with simple canoes and no navigation gear manage to find, let alone colonize, hundreds of far-flung island specks scattered across an ocean that spans nearly a third of the globe? Answers have been slow in coming. But now a startling archaeological find on the island of Éfaté, in the Pacific nation of Vanuatu, has revealed an ancient seafaring people, the distant ancestors of today’s Polynesians, taking their first steps into the unknown. The discoveries there have also opened a window into the shadowy world of those early voyagers.

C “What we have is a first- or second-generation site containing the graves of some of the Pacific’s first explorers,” says Spriggs, professor of archaeology at the Australian National University and co-leader of an international team excavating the site. It came to light only by luck. A backhoe operator, digging up topsoil on the grounds of a derelict coconut plantation, scraped open a grave – the first of dozens in a burial ground some 3,000 years old. It is the oldest cemetery ever found in the Pacific islands, and it harbors the bones of an ancient people archaeologists call the Lapita, a label that derives from a beach in New Caledonia where a landmark cache of their pottery was found in the 1950s.

D They were daring blue-water adventurers who roved the sea not just as explorers but also as pioneers, bringing along everything they would need to build new lives – their families and livestock, taro seedlings and stone tools. Within the span of a few centuries, the Lapita stretched the boundaries of their world from the jungle-clad volcanoes of Papua New Guinea to the loneliest coral outliers of Tonga, at least 2,000 miles eastward in the Pacific. Along the way they explored millions of square miles of an unknown sea, discovering and colonizing scores of tropical islands never before seen by human eyes: Vanuatu, New Caledonia, Fiji, Samoa.

It was their descendants, centuries later, who became the great Polynesian navigators we all tend to think of: the Tahitians and Hawaiians, the New Zealand Maori, and the curious people who erected those statues on Easter Island. But it was the Lapita who laid the foundation – who bequeathed to the island the language, customs, and cultures that their more famous descendants carried around the Pacific.

E While the Lapita left a glorious legacy, they also left precious few clues about themselves. A particularly intriguing clue comes from chemical tests on the teeth of several skeletons. Then as now, the food and water you consume as a child deposits oxygen, carbon, strontium, and other elements in your still-forming adult teeth. The isotope signatures of these elements vary subtly from place to place, so that if you grow up in, say, Buffalo, New York, then spend your adult life in California, tests on the isotopes in your teeth will always reveal your eastern roots.

Isotope analysis indicates that several of the Lapita buried on Éfaté didn’t spend their childhoods here but came from somewhere else. And while isotopes can’t pinpoint their precise island of origin, this much is clear: At some point in their lives, these people left the villages of their birth and made a voyage by seagoing canoe, never to return. DNA teased from these ancient bones may also help answer one of the most puzzling questions in Pacific anthropology: Did all Pacific islanders spring from one source or many? Was there only one outward migration from a single point in Asia, or several from different points? “This represents the best opportunity we’ve had yet,” says Spriggs, “to find out who the Lapita actually were, where they came from, and who their closest descendants are today.”

F There is one stubborn question for which archaeology has yet to provide any answers: How did the Lapita accomplish the ancient equivalent of a moon landing, many times over? No one has found one of their canoes or any rigging, which could reveal how the canoes were sailed. Nor do the oral histories and traditions of later Polynesians offer any insights.

“All we can say for certain is that the Lapita had canoes that were capable of ocean voyages, and they had the ability to sail them,” says Geoff Irwin, a professor of archaeology at the University of Auckland and an avid yachtsman. Those sailing skills, he says, were developed and passed down over thousands of years by earlier mariners who worked their way through the archipelagoes of the western Pacific making short crossings to islands within sight of each other. The real adventure didn’t begin, however, until their Lapita descendants neared the end of the Solomons chain, for this was the edge of the world. The nearest landfall, the Santa Cruz Islands, is almost 230 miles away, and for at least 150 of those miles, the Lapita sailors would have been out of sight of land, with empty horizons on every side.

G The Lapita’s thrust into the Pacific was eastward, against the prevailing trade winds, Irwin notes. Those nagging headwinds, he argues, may have been the key to their success. “They could sail out for days into the unknown and reconnoiter, secure in the knowledge that if they didn’t find anything, they could turn about and catch a swift ride home on the trade winds. It’s what made the whole thing work.” Once out there, skilled seafarers would detect abundant leads to follow to land: seabirds and turtles, coconuts and twigs carried out to sea by the tides and the afternoon pileup of clouds on the horizon that often betokens an island in the distance.

All this presupposes one essential detail, says Atholl Anderson, professor of prehistory at the Australian National University and, like Irwin, a keen yachtsman: that the Lapita had mastered the advanced art of tacking into the wind. “And there’s no proof that they could do any such thing,” Anderson says. “There has been this assumption that they must have done so, and people have built canoes to re-create those early voyages based on that assumption. But nobody has any idea what their canoes looked like or how they were rigged.”

H However they did it, the Lapita spread themselves a third of the way across the Pacific, then called it quits for reasons known only to them. Ahead lay the vast emptiness of the central Pacific, and perhaps they were too thinly stretched to venture farther. They probably never numbered more than a few thousand in total, and in their rapid migration eastward they encountered hundreds of islands – more than 300 in Fiji alone. Supplied with such an embarrassment of riches, they could settle down and enjoy what for a time was Earth’s last Edens.

I Rather than give all the credit to human skill and daring, Anderson invokes the winds of change. El Niño, the same climate disruption that affects the Pacific today, may have helped scatter the first settlers to the ends of the ocean, Anderson suggests. Climate data obtained from slow-growing corals around the Pacific and from lake-bed sediments in the Andes of South America point to a series of unusually frequent El Niño around the time of the Lapita expansion, and again between 1,600 and 1,200 years ago, when the second wave of pioneer navigators made their voyages farther east, to the remotest corners of the Pacific. By reversing the regular east-to-west flow of the trade winds for weeks at a time, these “super El Niño” might have sped the Pacific’s ancient mariners on long, unplanned voyages could have been key to launching Polynesians across the wide expanse of open water between Tonga, where the Lapita stopped, and the distant archipelagoes of eastern Polynesia. “Once they crossed that gap, they could island-hop throughout the region, and from the Marquesas, it’s mostly downwind to Hawaii,” Anderson says. It took another 400 years for mariners to reach Easter Island, which lies in the opposite direction – normally upwind. “Once again this was during a period of frequent El Niño activity.”

The Hidden Lives Of Solitary Bees

There are 275 different species of bee in Greet Britain and Ireland. Apart from the familiar honeybee and 25 species of bumblebee, the rest are known as solitary bees

Solitary bees are unlike ‘social’ honeybees and bumblebees, which live in large colonies consisting of a queen whose function is to lay the eggs, while the workers gather pollen and nectar to feed the tiny grubs with solitary bees, there are typically just males and females. They mate, the mate dies and the female makes a nest.

Ian Beavis is a naturalist and blogger with a mission to raise the profile of the many solitary bees, whose pollinating services are so important, yet so little recognised, Solitary bees inhabit gardens, parks, woodlands, fields and cliffs. In fact they represent 95% of the world’s bee species. Leading wildlife illustrator Richard Lewington. best known for his beautiful paintings of butterflies, says, ‘Solitary bees are so useful to gardeners and commercially valuable. Yet until recently they barely registered in the public consciousness. I wanted to help publicise their vital role in our lives’ The problem with solitary bees has long been one of identification – with more than 240 species to choose from, and no accessible guidebook, where do people start? So Richard Lewington has spent any spare time over the past few years working on a new guide to the bees of Great Britain and Ireland. This, amazingly, is the first book of its kind to be published for over a century.

How do solitary bees live? A female solitary bee constructs a nest and then lays her eggs in individual cells, lining or sealing them with various materials depending on the species of bee – red mason bees use mud leafcutter bees use sections of leaf The female leaves what naturalists call a ‘parcel’ of pollen and nectar for each other little grubs to feed on When the female has laid all her eggs, she dies. The emerging grubs eat. grow and develop into adults the following year.

While some bees are plentiful and widespread, others have been designated as rare. Or are very local in distribution. In 2013. Ian Beavis came across what has long been known as one of Britain’s rarest species, the banded mining bee. An impressive species with white hairs on its face, the banded mining bee nests in the ground, typically on steep banks. Ian Beavis explains that it always chooses bare earth because it doesn’t like having to eat through plant roots to make its nest Females feed on a variety of plants, but seem particularly fond of yellow dandelions that bloom from spring to autumn.

Another bee that has attracted naturalists’ attention is the ivy bee. It was only identified as a distinct species in 1993. It is one of a number of bees that have been able to establish themselves in Britain due to the recent warmer winters. About the same size as a with distinctive orange-yellow banding on its abdomen, it was initially thought to feed on y on ivy, but has since been seen visiting other plants.

The discoveries about ivy bees show how rewarding the study of solitary bees can be but it’s not the only species whose habits are changing. Ian Beavis believes we can see in solitary bees the beginning of social behaviour. He explains that many species make their nests close to each other in huge groups, and there are some, like Andrena scotica, where several bees use the same entrance without becoming aggressive. It’s not difficult to see how this behaviour, which could be seen as the foundation of social behaviour, might evolve in future into worker bees sharing care of the grubs. Indeed some of Britain’s solitary bees, Lasioglossum malachurum for example, are already demonstrating this type of social behaviour. So will all solitary bees evolve into social insects? Not necessarily. According to Ian Beavis, there are advantages to social behaviour but there are also advantages to nesting alone. Bees that nest socially are a target for predators, diseases and parasites.

Pesticides can also pose a threat to solitary bees. At the University of Sussex in England. Beth Nicholls is conducting research into the effects of certain pesticides on the red mason bee. She explains. ‘We know that pesticides harm social bees, but very little research has been done into solitary bees.’ Honeybees fly throughout the summer, so they may be exposed to different levels of pesticides. But if the shorter flight period of solitary bees – the red mason bee only flies from March to May – coincides with peak pesticide levels, that might be disastrous. If the red mason bee declines dramatically, it could affect the fruit growing industry. According to Beth Nicholls, it is much more efficient at pollinating orchard trees. Social bees carry pollen in ‘baskets’ on their back legs, but a female red mason bee carries it on the underside of her abdomen. This is a messier way of transporting it, and so more pollen is transferred to other flowers. The social bees’ method is much ‘tidier’, so once they have collected the pollen and tucked it away behind their legs, it won’t be dropped.

Solitary bees are all around us. We need to start paying attention to them before it’s too late.

How War Debris Could Cause Cancer

A Could the mystery over how depleted uranium might cause genetic damage be closer to being solved? It may be, if a controversial claim by two researchers is right. They say that minute quantities of the material lodged in the body may kick out energetic electrons that mimic the effect of beta radiation. This, they argue, could explain how residues of depleted uranium scattered across former war zones could be increasing the risk of cancers and other problems among soldiers and local people.

B Depleted uranium is highly valued by the military, who use it in the tips of armour­piercing weapons. The material’s high density and self-sharpening properties help it to penetrate the armour of enemy tanks and bunkers. Its use in conflicts has risen sharply in recent years. The UN Environment Programme (UNEP) estimates that shells containing 1700 tonnes of the material were fired during the 2003 Iraq war. Some researchers and campaigners are convinced that depleted uranium left in the people exposed to it. Governments and the military disagree, and point out that there is no conclusive epidemiological evidence for this. And while they acknowledge that the material is weakly radioactive, they say this effect is too small to explain the genetic damage at the levels seen in war veterans and civilians.

C Organisations such as the UK’s Royal Society, the US Department of Veterans Affairs and UNEP have called for more comprehensive epidemiological studies to clarify the link between depleted uranium and any ill effects. Meanwhile, various test­tube and animal studies have suggested that depleted uranium may increase the risk of cancer, according to a review of the scientific literature published in May 2008 by the US National Research Council. The authors of the NRC report argue that more long-term and quantitative research is needed on the effects of uranium’s chemical toxicity. They say the science seems to support the theory that genetic damage might be occurring because uranium’s chemical toxicity and weak radioactivity could somehow reinforce each other, though no one knows what the mechanism for this might be.

D Now two researchers, Chris Busby and Ewald Schnug, have a new theory that they say explains how depleted uranium could cause genetic damage. Their theory invokes a well-known process called the photoelectric effect. This is the main mechanism by which gamma photons with energies of about 100 kiloelectronvolts (keV) or less are blocked by matter: the photon transfers its energy to an electron in the atom’s electron cloud, which is ejected into the surroundings.

An atom’s ability to stop photons by this mechanism depends on the fourth power of its atomic number – the number of protons in its nucleus – so heavy elements are far better at intercepting gamma radiation and X-rays than light elements. This means that uranium could be especially effective at capturing photons and kicking out damaging photoelectrons: with an atomic number of 92, uranium blocks low-energy gamma photons over 450 times as effectively as the lighter element calcium, for instance.

E Busby and Schnug say that previous risk models have ignored this well-established physical effect. They claim that depleted uranium could be kicking out photoelectrons in the body’s most vulnerable spots. Various studies have shown that dissolved uranium – ingested in food or water, for example – is liable to attach to DNA strands within cells, because uranium binds strongly to DNA phosphate. “Photoelectrons from uranium are therefore likely to be emitted precisely where they will cause most damage to genetic material,” says Busby.

F Busby and Schnug base their claim on calculations of the photoelectrons that would be produced by the interation between normal background levels of gamma radiation and uranium in the body. “Our detailed calculations indicate that the phantom photoelectrons are the predominant effect by far for uranium genome toxicity, and that uranium could be 1500 times as powerful as an emitter of photoelectrons than as an alpha emitter.” Their computer modelling results are described in a peer-reviewed paper to be published in this month by the IPNSS in a book called Loads and Fate of Fertiliser Derived Uranium.

G Hans-Georg Menzel, who chairs the International Commission on Radiological Protection’s committee on radiation doses, acknowledges that the theory should be considered, but he doubts that it will prove significant. He suspects that under normal background radiation the effect is too weak to inflict many of the “double hits” of energy that are known to be most damaging to cells. “It is very unlikely that individual cells would be subject to two or more closely spaced photoelectron impacts under normal background gamma irradiation,” he says. Despite his doubts, Menzel raised the issue last week with his committee in St Petersburg, Russia, and says that several colleagues “intended to collect relevant data and perform calculations to check whether there was any possibility of a real effect in living tissues”. Organisations in the UK, including the Ministry of Defence and the Health Protection Agency, say they have no plans to investigate Busby’s hypothesis.

H Radiation biophysicist Mark Hill of the University of Oxford would like to see a fuller investigation, though he suggests this might show that the photoelectric effect is not as powerful as Busby claims. “We really need more detailed calculations and dose estimates for realistic situations with and without uranium present,” he says. Hill’s doubts centre on an effect called Compton scattering, which he believes needs to be factored into any calculations. With Compton scattering, uranium is only 4.5 times as effective as calcium at stopping gamma photons, so Hill says that taking it into account would reduce the relative importance of uranium as an emitter of secondary electrons. If he is right, this would dilute the mechanism proposed by Busby and Schnug.

I The arguments over depleted uranium are likely to continue, whatever the outcome of these experiments. Whether Busby’s theory holds up or not remains to be seen, but investigating it can only help to clear up some of the doubts about this mysterious substance.

The Discovery Of Uranus

Someone once put forward an attractive though unlikely theory. Throughout the Earth’s annual revolution around the sun, there is one point of space always hidden from our eyes. This point is the opposite part of the Earth’s orbit, which is always hidden by the sun. Could there be another planet there, essentially similar to our own, but always invisible?

If a space probe today sent back evidence that such a world existed it would cause not much more sensation than Sir William Herschel’s discovery of a new planet, Uranus, in 1781. Herschel was an extraordinary man — no other astronomer has ever covered so vast a field of work — and his career deserves study. He was born in Hanover in Germany in 1738, left the German army in 1757, and arrived in England the same year with no money but quite exceptional music ability. He played the violin and oboe and at one time was organist in the Octagon Chapel in the city of Bath. Herschel’s was an active mind, and deep inside he was conscious that music was not his destiny; he therefore, read widely in science and the arts, but not until 1772 did he come across a book on astronomy. He was then 34, middle-aged by the standards of the time, but without hesitation he embarked on his new career, financing it by his professional work as a musician. He spent years mastering the art of telescope construction, and even by present-day standards his instruments are comparable with the best.

Serious observation began 1774. He set himself the astonishing task of ‘reviewing the heavens’, in other words, pointing his telescope to every accessible part of the sky and recording what he saw. The first review was made in 1775; the second, and most momentous, in 1780-81. It was during the latter part of this that he discovered Uranus. Afterwards, supported by the royal grant in recognition of his work, he was able to devote himself entirely to astronomy. His final achievements spread from the sun and moon to remote galaxies (of which he discovered hundreds), and papers flooded from his pen until his death in 1822. Among these, there was one sent to the Royal Society in 1781, entitled An Account of a Comet. In his own words:

On Tuesday the 13th of March, between ten and eleven in the evening, while I was examining the small stars in the neighbourhood of H Geminorum, I perceived one that appeared visibly larger than the rest; being struck with its uncommon magnitude, I compared it to H Geminorum and the small star in the quartile between Auriga and Gemini, and finding it to be much larger than either of them, suspected it to be a comet.

Herschel’s care was the hallmark of a great observer; he was not prepared to jump any conclusions. Also, to be fair, the discovery of a new planet was the last thought in anybody’s mind. But further observation by other astronomers besides Herschel revealed two curious facts. For the comet, it showed a remarkably sharp disc; furthermore, it was moving so slowly that it was thought to be a great distance from the sun, and comets are only normally visible in the immediate vicinity of the sun. As its orbit came to be worked out the truth dawned that it was a new planet far beyond Saturn’s realm, and that the ‘reviewer of the heavens’ had stumbled across an unprecedented prize. Herschel wanted to call it georgium sidus (Star of George) in honour of his royal patron King George III of Great Britain. The planet was later for a time called Herschel in honour of its discoverer. The name Uranus, which was first proposed by the German astronomer Johann Elert Bode, was in use by the late 19th century.

Uranus is a giant in construction, but not so much in size; its diameter compares unfavourably with that of Jupiter and Saturn, though on the terrestrial scale it is still colossal. Uranus’ atmosphere consists largely of hydrogen and helium, with a trace of methane. Through a telescope the planet appears as a small bluish-green disc with a faint green periphery. In 1977, while recording the occultation 1 of a star behind the planet, the American astronomer James L. Elliot discovered the presence of five rings encircling the equator of Uranus. Four more rings were discovered in January 1986 during the exploratory flight of Voyager 2 2 , In addition to its rings, Uranus has 15 satellites (‘moons’), the last 10 discovered by Voyager 2 on the same flight; all revolve about its equator and move with the planet in an east—west direction. The two largest moons, Titania and Oberon, were discovered by Herschel in 1787. The next two, Umbriel and Ariel, were found in 1851 by the British astronomer William Lassell. Miranda, thought before 1986 to be the innermost moon, was discovered in 1948 by the American astronomer Gerard Peter Kuiper.

Reclaiming the future of aral sea

A The Aral Sea gets almost all its water from the Amu and Syr rivers. Over millennium the Amu’s course has drifted away from the sea, causing it to shrink. But the lake always rebounded as the Amu shifted back again. Today heavy irrigation for crops such as cotton and rice siphons off much of the two rivers, severely cutting flow into their deltas and thus into the sea. Evaporation vastly outpaces any rainfall, snowmelt or groundwater supply, reducing water volume and raising salinity. The Soviet Union hid the sea’s demise for decades until 1985, when leader Mikhail Gorbachev revealed the great environmental and human tragedy. By the late 1980s the sea’s level had dropped so much that the water had separated into two distinct bodies: the Small Aral (north) and the Large Aral (south). By 2007 the south had split into a deep western basin, a shallow eastern basin and a small, isolated gulf. The Large Aral’s volume had dropped from 708 to only 75 cubic kilometers (km3), and salinity had risen from 14 to more than 100 grams per liter (g/1). The 1991 dissolution of the Soviet Union divided the lake between newly formed Kazakhstan and Uzbekistan, ending a grand Soviet plan to channel in water from distant Siberian rivers and establishing competition for the dwindling resource.

B Desiccation of the Aral Sea has wrought severe consequences. Greatly reduced river flows ended the spring floods that sustained wetlands with freshwater and enriched sediment. Fish species in the lakes dropped from 32 to 6 because of rising salinity and loss of spawning and feeding grounds (most survived in the river deltas). Commercial fisheries, which caught 40,000 metric tons of fish in 1960, were gone by the mid-1980s; more than 60,000 related jobs were lost. The most common remaining lake occupant was the Black Sea flounder, a saltwater fish introduced in the 1970s, but by 2003 it had disappeared from the southern lakes because salinity was more than 70 g/1, double that of a typical ocean. Shipping on the Aral also ceased because the water receded many kilometers from the major ports of Aralsk to the north and Moynak in the south; keeping increasingly long channels open to the cities became too costly. Groundwater levels dropped with falling lake levels, intensifying desertification.

C The receding sea has exposed and dried 54,000 square kilometers of seabed, which is choked with salt and in some places laced with pesticides and other agricultural chemicals deposited by runoff from area farming. Strong windstorms blow salt, dust and contaminants as far as 500 km. Winds from the north and northeast drive the most severe storms, seriously impacting the Amu delta to the south—the most densely settled and most economically and ecologically important area in the region. Afrbome sodium bicarbonate, sodium chloride and sodium sulfate kill or retard the growth of natural vegetation and crops—a cruel irony given that irrigating those crops starves the sea. Health experts say the local population suffers from high levels of respiratory illnesses, throat and esophageal cancer, and digestive disorders caused by breathing and ingesting salt-laden air and water. Liver and kidney ailments, as well as eye problems, are common. The loss of fish has also greatly reduced dietary variety, worsening malnutrition and anemia, particularly in pregnant women.

D Returning the entire Aral Sea to its 1960s state is unrealistic. The annual inflow from the Syr and Amu rivers would have to be quadrupled from the recent average of 13 km3. The only means would be to curtail irrigation, which accounts for 92 percent of water withdrawals. Yet four of the five former Soviet republics in the Aral Sea basin (Kazakhstan is the exception) intend to expand irrigation, mainly to feed growing populations. Switching to less water- intensive crops, such as replacing cotton with winter wheat, could help, but the two primary irrigating nations, Uzbekistan and Turkmenistan, intend to keep cotton to earn foreign currency. The extensive irrigation canals could be greatly improved; many are simply cuts through sand, and they allow enormous quantities of water to seep away. Modernizing the entire system could save 12 km3 a year but would cost at least $16 billion. The basin states do not have the money or the political will. Kazakhstan has nonetheless tried to partially restore the northern Aral.

E We expect salinities in the Small Aral to settle at three to 14 g/1, depending on location. At these levels many more indigenous species should return, although the saltwater kambala would disappear from most places. Further restoration is possible. For example, if irrigation improvements raised the average annual inflow from the Syr to 4.5 km3, which is entirely feasible, the lake’s level could stabilize at about 47 meters. This change would bring the shoreline to within eight kilometers of Aralsk, the former major port city, close enough to allow recovery of an earlier channel that connected the city to the receding waters. The channel would give large commercial fishing vessels access to the sea, and shipping could restart. Marshlands and fish populations would improve even more because of a further reduction in salinity. Outflow to the southern lakes could also increase, helping then restoration. Such a plan would require a much longer and higher dike, as well as reconstruction of the gate facility, and it is not clear that Kazakhstan has the means or desire to pursue it. The country is, however, now discussing more modest proposals to bring water closer to Aralsk.

F The Large Aral faces a difficult future; it continues to shrink rapidly. Only a long, narrow channel connects the shallow eastern basin and the deeper western basin, and this could close altogether. If countries along the Amu make no changes, we estimate that at current rates of groundwater in and evaporation out, an isolated eastern basin would stabilize at an area of 4,300 square kilometers (km2). But it would average only 2.5 meters deep. Salinity would exceed 100 g/1, possibly reaching 200 g/1; the only creatures that could live in it would be brine shrimp and bacteria. The western basin’s fate depends on ground- water inflow, estimates for which are uncertain. Someone has noted numerous fresh- water springs on the western cliffs. The most reliable calculations indicate that the basin would settle at about 2,100 km2. The lake would still be relatively deep, reaching 37 meters in spots, but salinity would rise well above 100 g/1.

Conflicting climatic phenomena co-existing on the Mars

A On Mars, signs of wetness keep pouring in: deeply carved river valleys, vast deltas and widespread remnants of evaporating seas have convinced many experts that liquid water may have covered large parts of the Red Planet for a billion years or more. But most efforts to explain how Martian climate ever permitted such clement conditions come up dry. Bitterly cold and parched today, Mars needed a potent greenhouse atmosphere to sustain its watery past. A thick layer of heat-trapping carbon dioxide from volcanoes probably shrouded the young planet, but climate models indicate time and again that C02 alone could not have kept the surface above freezing.

B Now, inspired by the surprising discovery that sulfur minerals are pervasive in the Martian soil, scientists are beginning to suspect that C02 had a warm-up partner: sulfur dioxide (S02). Like C02, S02 is a common gas emitted when volcanoes erupt, a frequent occurrence on Mars when it was still young. A hundredth or even a thousandth of a percent S02 in Mars’s early atmosphere could have provided the extra boost of greenhouse warming that the Red Planet needed to stay wet, explains geochemist Daniel p. Schrag of Harvard University.

C That may not sound like much, but for many gases, even minuscule concentrations are hard to maintain. On our home planet, S02 provides no significant long-term warmth because it combines almost instantly with oxygen in the atmosphere to form sulfate, a type of salt. Early Mars would have been virtually free of atmospheric oxygen, though, so S02 would have stuck around much longer.

D “When you take away oxygen, it’s a profound change, and the atmosphere works really differently,” Schrag remarks. According to Schrag and his colleagues, that difference also implies that S02 would have played a starring role in the Martian water cycle—thus resolving another climate conundrum, namely, a lack of certain rocks.

E Schrag’s team contends that on early Mars, much of the S02 would have combined with airborne water droplets and fallen as sulfurous acid rain, rather than transforming into a salt as on Earth. The resulting acidity would have inhibited the formation of thick layers of limestone and other carbonate rocks. Researchers assumed Mars would be chock-full of carbonate rocks because their formation is such a fundamental consequence of the humid, C02-rich atmosphere. Over millions of years, this rock-forming process has sequestered enough of the carbon dioxide spewed from earthly volcanoes to limit the buildup of the gas in the atmosphere. stifling this C02-sequestration step on early Mars would have forced more of the gas to accumulate in the atmosphere—another way S02 could have boosted greenhouse warming, Schrag suggests.

F Some scientists doubt that S02 was really up to these climatic tasks . Even in an oxygen-free atmosphere, S02 is still extremely fragile; the sun’s ultraviolet radiation splits apart S02 molecules quite readily, points out James F. Kasting, an atmospheric chemist at Pennsylvania state University. In Easting’s computer models of Earth’s early climate, which is often compared with that of early Mars, this photochemical destruction capped S02 concentrations at one thousandth as much as Schrag and his colleagues describe. “There may be ways to make this idea work,” Kasting says. “But it would take some detailed modeling to convince skeptics, including me, that it is actually feasible.”

G Schrag admits that the details are uncertain, but he cites estimates by other researchers who suggest that early Martian volcanoes could have spewed enough S02 to keep pace with the S02 destroyed photochemically. Previous findings also indicate that a thick C02 atmosphere would have effectively scattered the most destructive wavelengths of ultraviolet radiation—yet another example of an apparently mutually beneficial partnership between C02 and S02 on early Mars.

H Kasting maintains that an S02 climate feedback could not have made early Mars as warm as Earth, but he does allow for the possibility that S02 concentrations may have remained high enough to keep the planet partly defrosted, with perhaps enough rainfall to form river valleys. Over that point, Schrag does not quibble. “Our hypothesis doesn’t depend at all on whether there was a big ocean, a few lakes or just a few little puddles,” he says. ” Warm doesn’t mean warm like the Amazon. It could mean warm like Iceland— just warm enough to create those river valleys . ” with S02, it only takes a little. If sulfur dioxide warmed early Mars, as a new hypothesis suggests, minerals called sulfites would have formed in standing water at the surface. No sulfites have yet turned up, possibly because no one was looking for them. The next-generation rover, the Mars Science Laboratory, is well equipped for the search. Scheduled to launch in 2009, the rover (shown here in an artist’s conception) will be the first to carry an x-ray diffractometer, which can scan and identify the crystal structure of any mineral it encounters.

The Nagymaros Dam

When Janos Vargha, a biologist from the Hungarian Academy of Sciences, began a new career as a writer with a small monthly nature magazine called Buvar, it was 9 years after the story behind the fall of the Berlin Wall had started to unfold. During his early research, he went to a beauty spot on the river Danube outside Budapest known as the Danube Bend to interview local officials about plans to build a small park on the site of an ancient Hungarian capital.

One official mentioned that passing this tree-lined curve in the river, a popular tourism spot for Hungarians was monotonous. Also, it was to be submerged by a giant hydroelectric dam in secret by a much-feared state agency known simply as the Water Management.

Vargha investigated and learned that the Nagymaros dam (pronounced “nosh-marosh”) would cause pollution, destroy underground water reserves, dry out wetlands and wreck the unique ecosystem of central Europe’s longest river. Unfortunately, nobody objected. “Of course, I wrote an article. But there was a director of the Water Management on the magazine’s editorial board. The last time, he went to the printers and stopped the presses, the article was never published. I was frustrated and angry, but I was ultimately interested in why they cared to ban my article,” he remembers today.

He found that the Nagymaros dam was part of a joint project with neighbouring Czechoslovakia to produce hydroelectricity, irrigate farms and enhance navigation. They would build two dams and re-engineer the Danube for 200 kilometres where it created the border between them. “The Russians were working together, too. They wanted to take their big ships from the Black Sea right up the Danube to the border with Austria.”

Vargha was soon under vigorous investigation, and some of his articles got past the censors. He gathered supporters for some years, but he was one of only a few people who believed the dam should be stopped. He was hardly surprised when the Water Management refused to debate the project in public. After a public meeting, the bureaucrats had pulled out at the last minute. Vargha knew he had to take the next step. “We decided it wasn’t enough to talk and write, so we set up an organization, the Danube Circle. We announced that we didn’t agree with censorship. We would act as if we were living in a democracy.” he says.

The Danube Circle was illegal and the secret publications it produced turned out to be samizdat leaflets. In an extraordinary act of defiance, it gathered 10,000 signatures for a petition objecting to the dam and made links with environmentalists in the west, inviting them to Budapest for a press conference.

The Hungarian government enforced a news blackout on the dam, but articles about the Danube Circle began to be published and appear in the western media. In 1985, the Circle and Vargha, a public spokesman, won the Right Livelihood award known as the alternative Nobel prize. Officials told Vargha he should not take the prize but he ignored them. The following year when Austrian environmentalists joined a protest in Budapest, they were met with tear gas and batons. Then the Politburo had Vargha taken from his new job as editor of the Hungarian version of Scientific American.

The dam became a focus for opposition to the hated regime. Communists tried to hold back the waters in the Danube and resist the will of the people. Vargha says, “Opposing the state directly was still hard.” “Objecting to the dam was less of a hazard, but it was still considered a resistance to the state.”

Under increasing pressure from the anti-dam movement, the Hungarian Communist Party was divided. Vargha says, “Reformists found that the dam was not very popular and economical. It would be cheaper to generate electricity by burning coal or nuclear power.” “But hardliners were standing for Stalinist ideas of large dams which mean symbols of progress.” Environmental issues seemed to be a weak point of east European communism in its final years. During the 1970s under the support of the Young Communist Leagues, a host of environmental groups had been founded. Party officials saw them as a harmless product of youthful idealism created by Boy Scouts and natural history societies.

Green idealism steadily became a focal point for political opposition. In Czechoslovakia, the human rights of Charter 77 took up environmentalism. The green-minded people of both Poland and Estonia participated in the Friends of the Earth International to protest against air pollution. Bulgarian environmentalists built a resistance group, called Ecoglasnost, which held huge rallies in 1989. Big water engineering projects were potent symbols of the old Stalinism.

Radio Automation

Today they are everywhere. Production lines controlled by computers and operated by robots. There’s no chatter of assembly workers, just the whirr and click of machines. In the mid-1940s, the workerless factory was still the stuff of science fiction. There were no computers to speak of and electronics was primitive. Yet hidden away in the English countryside was a highly automated production line called ECME, which could turn out 1500 radio receivers a day with almost no help from human hands.

A John Sargrove, the visionary engineer who developed the technology, was way ahead of his time. For more than a decade, Sargrove had been trying to figure out how to make cheaper radios. Automating the manufacturing process would help. But radios didn’t lend themselves to such methods: there were too many parts to fit together and too many wires to solder. Even a simple receiver might have 30 separate components and 80 hand-soldered connections. At every stage, things had to be tested and inspected. Making radios required highly skilled labour—and lots of it.

B In 1944, Sargrove came up with the answer. His solution was to dispense with most of the fiddly bits by inventing a primitive chip—a slab of Bakelite with all the receiver’s electrical components and connections embedded in it. This was something that could be made by machines, and he designed those too. At the end of the war, Sargrove built an automatic production line, which he called ECME (electronic circuit-making equipment), in a small factory in Effingham, Surrey.

C An operator sat at one end of each ECME line, feeding in die plates. She didn’t need much skill, only quick hands. From now on, everything was controlled by electronic switches and relays. First stop was the sandblaster, which roughened the surface of the plastic BO that molten metal would stick to it The plates were then cleaned to remove any traces of grit The machine automatically checked that the surface was rough enough before sending the plate to the spraying section. There, eight nozzles rotated into position and sprayed molten zinc over both sides of the plate. Again, the nozzles only began to spray when a plate was in place. The plate whizzed on. The next stop was the milling machine, which ground away the surface layer of metal to leave the circuit and other components in the grooves and recesses. Now the plate was a composite of metal and plastic. It sped on to be lacquered and have its circuits tested. By the time it emerged from the end of the line, robot hands had fitted it with sockets to attach components such as valves and loudspeakers. When ECME was working flat out; the whole process took 20 seconds.

D ECME was astonishingly advanced. Electronic eyes, photocells that generated a small current when a panel arrived, triggered each step in the operation, BO avoiding excessive wear and tear on the machinery. The plates were automatically tested at each stage as they moved along the conveyor. And if more than two plates in succession were duds, the machines were automatically adjusted—or if necessary halted In a conventional factory, I workers would test faulty circuits and repair them. But Sargrove’s assembly line produced circuits so cheaply they just threw away the faulty ones. Sargrove’s circuit board was even more astonishing for the time. It predated the more familiar printed circuit, with wiring printed on aboard, yet was more sophisticated. Its built-in components made it more like a modem chip.

E When Sargrove unveiled his invention at a meeting of the British Institution of Radio Engineers in February 1947, the assembled engineers were impressed. So was the man from The Times. ECME, he reported the following day, “produces almost without human labour, a complete radio receiving set. This new method of production can be equally well applied to television and other forms of electronic apparatus.

F The receivers had many advantages over their predecessors, wit components they were more robust. Robots didn’t make the sorts of mistakes human assembly workers sometimes did. “Wiring mistakes just cannot happen,” wrote Sargrove. No w ừ es also meant the radios were lighter and cheaper to ship abroad. And with no soldered wires to come unstuck, the radios were more reliable. Sargrove pointed out that the drcuit boards didn’t have to be flat. They could be curved, opening up the prospect of building the electronics into the cabinet of Bakelite radios.

G Sargrove was all for introducing this type of automation to other products. It could be used to make more complex electronic equipment than radios, he argued. And even if only part of a manufacturing process were automated, the savings would be substantial. But while his invention was brilliant, his timing was bad. ECME was too advanced for its own good. It was only competitive on huge production runs because each new job meant retooling the machines. But disruption was frequent. Sophisticated as it was, ECME still depended on old- fashioned electromechanical relays and valves—which failed with monotonous regularity. The state of Britain’s economy added to Sargrove’s troubles. Production was dogged by power cuts and post-war shortages of materials. Sargrove’s financial backers began to get cold feet.

H There was another problem Sargrove hadn’t foreseen. One of ECME’s biggest advantages—the savings on the cost of labour—also accelerated its downfall. Sargrove’s factory had two ECME production lines to produce the two c ữ cuits needed for each radio. Between them these did what a thousand assembly workers would otherwise have done. Human hands were needed only to feed the raw material in at one end and plug the valves into then sockets and fit the loudspeakers at the other. After that, the only job left was to fit the pair of Bakelite panels into a radio cabinet and check that it worked.

I Sargrove saw automation as the way to solve post-war labour shortages. With somewhat Utopian idealism, he imagined his new technology would free people from boring, repetitive jobs on the production line and allow them to do more interesting work. “Don’t get the idea that we are out to rob people of then jobs,” he told the Daily Mnror. “Our task is to liberate men and women from being slaves of machines.”

J The workers saw things differently. They viewed automation in the same light as the everlasting light bulb or the suit that never wears out—as a threat to people’s livelihoods. If automation spread, they wouldn’t be released to do more exciting jobs. They’d be released to join the dole queue. Financial backing for ECME fizzled out. The money dried up. And Britain lost its lead in a technology that would transform industry just a few years later.

The Cacao: A Sweet history

A Chapter 1
Most people today think of chocolate as something sweet to eat or drink that can be easily found in stores around the world. It might surprise you that chocolate was once highly treasured. The tasty secret of the cacao (Kah Kow) tree was discovered 2,000 years ago in the tropical rainforests of the Americas. The story of how chocolate grew from a local Mesoamerican beverage into a global sweet encompasses many cultures and continents.

B Chapter 2
Historians believe the Maya people of Central America first learned to farm cacao plants around two thousand years ago. The Maya took cacao trees from the rainforests and grew them in their gardens. They cooked cacao seeds, the crushed them into a soft paste. They mixed the paste with water and flavorful spices to make an unsweetened chocolate drink. The Maya poured the chocolate drink back and forth between two containers so that the liquid would have a layer of bubbles or foam.

Cacao and chocolate were an important part of Maya culture. There are often images of cacao plants on Maya buildings and art objects. Ruling families drank chocolate at special ceremonies. And, even poorer members of society could enjoy the drink once in a while. Historians believe that cacao seeds were also used in marriage ceremonies as a sign of the union between a husband and a wife.

The Aztec culture in current-day Mexico also prized chocolate. But, cacao plants could not grow in the area where the Aztecs lived. So, they traded to get cacao. They even used cacao seeds as a form of money to pay taxes. Chocolate also played a special role in both Maya and Aztec royal and religious events. Priests presented cacao seeds and offerings to the gods and served chocolate drinks during sacred ceremonies. Only the very wealthy in Aztec societies could afford to drink chocolate because cacao was so valuable. The Aztec ruler Montezuma was believed to drink fifty cups of chocolate every day. Some experts believe the word for chocolate came from the Aztec word “xocolatl” which in the Nahuatl language means “bitter water.” Others believe the word “chocolate” was created by combining Mayan and Nahuatl words.

C Chapter 3
The explorer Christopher Columbus brought cacao seeds to Spain after his trip to Central America in 1502. But it was the Spanish explorer Hernando Cortes who understood that chocolate could be a valuable investment. In 1519, Cortes arrived in current-day Mexico. He believed the chocolate drink would become popular with Spaniards. After the Spanish soldiers defeated the Aztec empire, they were able to seize the supplies of cacao and send them home. Spain later began planting cacao in its colonies in the Americans in order to satisfy the large demand for chocolate. The wealthy people of Spain first enjoyed a sweetened version of chocolate drink. Later, the popularity of the drink spread throughout Europe. The English, Dutch and French began to plant cacao trees in their own colonies. Chocolate remained a drink that only wealthy people could afford to drink until the eighteenth century. During the period known as the Industrial Revolution, new technologies helped make chocolate less costly to produce.

D Chapter 4
Farmers grow cacao trees in many countries in Africa, Central and South America. The trees grow in the shady areas of the rainforests near the Earth’s equator. But these trees can be difficult to grow. They require an exact amount of water, warmth, soil and protection. After about five years, cacao trees start producing large fruits called pods, which grow near the trunk of the tree. The seeds inside the pods are harvested to make chocolate. There are several kinds of cacao trees. Most of the world’s chocolate is made from the seed of the forastero tree. But farmers can also grow criollo or trinitario cacao plants. Cacao trees grown on farms are much more easily threatened by diseases and insects than wild trees. Growing cacao is very hard work for farmers. They sell their harvest on a futures market. This means that economic conditions beyond their control can affect the amount of money they will earn. Today, chocolate industry officials, activists, and scientists are working with farmers. They are trying to make sure that cacao can be grown in a way that is fair to the timers and safe for the environment.

E Chapter 5
To become chocolate, cacao seeds go through a long production process in a factory. Workers must sort, clean and cook the seeds. Then they break off the covering of the seeds so that only the inside fruit, or nibs, remain. Workers crush the nibs into a soft substance called chocolate liquor. This gets separated into cocoa solids and fat called cocoa butter. Chocolate makers have their own special recipes in which they combine chocolate liquor with exact amounts of sugar, milk and cocoa fat. They finely crush this “crumb” mixture in order to make it smooth. The mixture then goes through two more processes before it is shaped into a mold form.

Chocolate making is big business. The market value of the yearly cacao crop around the world is more than five billion dollars. Chocolate is especially popular in Europe and the United States. For example, in 2005, the United States bought 1.4 billion dollars worth of cocoa products. Each year, Americans eat an average of more than five kilograms of chocolate per person. Speciality shops that sell costly chocolates are also very popular. Many offer chocolate lovers the chance to taste chocolates grown in different areas of the world.

Extinct: the Giant Deer

Toothed cats, mastodons, giant sloths, woolly rhinos, and many other big, shaggy mammals are widely thought to have died out around the end of the last ice age, some 10,500 years ago.

A The Irish elk is also known as the giant deer (Megaloceros giganteus). Analysis of ancient bones and teeth by scientists based in Britain and Russia show the huge herbivore survived until about 5,000 B.C. – more than three millennia later than previously believed. The research team says this suggests additional factors, besides climate change, probably hastened the giant deer’s eventual extinction. The factors could include hunting or habitat destruction by humans.

B The Irish elk, so-called because its well-preserved remains are often found in lake sediments under peat bogs in Ireland, first appeared about 400,000 years ago in Europe and Central Asia. Through a combination of radiocarbon dating of skeletal remains and the mapping of locations where the remains were unearthed, the team shows the Irish elk was widespread across Europe before the last “big freeze.” The deer’s range later contracted to the Ural Mountains, in modern-day Russia, which separate Europe from Asia.

C The giant deer made its last stand in western Siberia, some 3,000 years after the ice sheets receded, said the study’s co-author, Adrian Lister, professor of palaeobiology at University College London, England. “The eastern foothills of the Urals became very densely forested about 8,000 years ago, which could have pushed them on to the plain,” he said. He added that pollen analysis indicates the region then became very dry in response to further climatic change, leading to the loss of important food plants. “In combination with human pressures, this could have finally snuffed them out,” Lister said.

D Hunting by humans has often been put forward as a contributory cause of extinction of the Pleistocene megafauna. The team, though, said their new date for the Irish elk’s extinction hints at an additional human-made problem – habitat destruction. Lister said, “We haven’t got just hunting 7,000 years ago – this was also about the time the first Neolithic people settled in the region. They were farmers who would have cleared the land.” The presence of humans may help explain why the Irish elk was unable to tough out the latest of many climatic fluctuations – periods it had survived in the past.

E Meanwhile, Lister cast doubt on another possible explanation for the deer’s demise – the male’s huge antlers. Some scientists have suggested this exaggerated feature – the result of females preferring stags with the largest antlers, possibly because they advertised a male’s fitness – contributed to the mammal’s downfall. They say such antlers would have been a serious inconvenience in the dense forests that spread northward after the last ice age. But, Lister said, “That’s a hard argument to make because the deer previously survived perfectly well through wooded interglacials [warmer periods between ice ages].” Some research has suggested that a lack of sufficient high-quality forage caused the extinction of the elk. High amounts of calcium and phosphate compounds are required to form antlers, and therefore large quantities of these minerals are required for the massive structures of the Irish Elk. The males (and male deer in general) met this requirement partly from their bones, replenishing them from food plants after the antlers were grown or reclaiming the nutrients from discarded antlers (as has been observed in extant deer). Thus, in the antler growth phase, Giant Deer was suffering from a condition similar to osteoporosis. When the climate changed at the end of the last glacial period, the vegetation in the animal’s habitat also changed towards species that presumably could not deliver sufficient amounts of the required minerals, at least in the western part of its range.

F The extinction of megafauna around the world was almost completed by the end of the last ice age. It is believed that megafauna initially came into existence in response to glacial conditions and became extinct with the onset of warmer climates. Tropical and subtropical areas have experienced less radical climatic change. The most dramatic of these changes was the transformation of a vast area of North Africa into the world’s largest desert. Significantly, Africa escaped major faunal extinction as did tropical and sub-tropical Asia. The human exodus from Africa and our entrance into the Americas and Australia were also accompanied by climate change. Australia’s climate changed from cold-dry to warm-dry. As a result, surface water became scarce. Most inland lakes became completely dry or dry in the warmer seasons. Most large, predominantly browsing animals lost their habitat and retreated to a narrow band in eastern Australia, where there were permanent water and better vegetation. Some animals may have survived until about 7000 years ago. If people have been in Australia for up to 60 000 years, then megafauna must have co-existed with humans for at least 30 000 years. Regularly hunted modern kangaroos survived not only 10 000 years of Aboriginal hunting, but also an onslaught of commercial shooters.

G The group of scientists led by A.J. Stuart focused on northern Eurasia, which he was taking as Europe, plus Siberia, essentially, where they’ve got the best data that animals became extinct in Europe during the Late Pleistocene. Some cold-adapted animals, go through into the last part of the cold stage and then become extinct up there. So you’ve actually got two phases of extinction. Now, neither of these coincide – these are Neanderthals here being replaced by modern humans. There’s no obvious coincidence between the arrival of humans or climatic change alone and these extinctions. There’s a climatic change here, so there’s a double effect here. Again, as animals come through to the last part of the cold stage, here there’s a fundamental change in the climate, reorganization of vegetation, and the combination of the climatic change and the presence of humans – of advanced Paleolithic humans – causes this wave of extinction. There’s a profound difference between the North American data and that of Europe, which summarize that the extinctions in northern Eurasia, in Europe, are moderate and staggered, and in North America severe and sudden. And these things relate to the differences in the timing of human arrival. The extinction follows from human predation, but only at times of fundamental changes in the environment.

Father of modern management

A Peter Drucker was one of the most important management thinkers of the past hundred years. He wrote about 40 book and thousands of articles and he never rested in his mission to persuade the world that management matters. “Management is an organ of institutions … the organ that converts a mob into an organisation, and human efforts into performance.” Did he succeed? The range of his influence was extraordinary. Wherever people grapple with tricky management problems, from big organizations to small ones, from the public sector to the private, and increasingly in the voluntary sector, you can find Drucker’s fingerprints.

B His first two books – The End of Economic Man (1939) and The Future of Industrial Man (1942) – had their admirers, including Winston Churchill, but they annoyed academic critics by ranging so widely over so many different subjects. Still, the second of these books attracted attention with its passionate insistence that companies had a social dimension as well as an economic purpose. His third book, The Concept of the Corporation, became an instant bestseller and has remained in print ever since.

C The two most interesting arguments in The Concept of the Corporation actually had little to do with the decentralization fad. They were to dominate his work. The first had to do with “empowering” workers. Drucker believed in treating workers as resources rather than just as costs. He was a harsh critic of the assembly-line system of production that then dominated the manufacturing sector – partly because assembly lines moved at the speed of the slowest and partly because they failed to engage the creativity of individual workers. The second argument had to do with the rise of knowledge workers. Drucker argued that the world is moving from an “economy of goods” to an economy of “knowledge” – and from a society dominated by an industrial proletariat to one dominated by brain workers. He insisted that this had profound implications for both managers and politicians. Managers had to stop treating workers like cogs in a huge inhuman machine and start treating them as brain workers. In turn, politicians had to realise that knowledge, and hence education, was the single most important resource for any advanced society. Yet Drucker also thought that this economy had implications for knowledge workers themselves. They had to come to terms with the fact that they were neither “bosses” nor “workers”, but something in between: entrepreneurs who had responsibility for developing their most important resource, brainpower, and who also needed to take more control of their own careers, including their pension plans.

D However, there was also a hard side to his work. Drucker was responsible for inventing one of the rational school of management’s most successful products – “management by objectives”. In one of his most substantial works, The Practice of Management (1954), he emphasised the importance of managers and corporations setting clear long-term objectives and then translating those long-term objectives into more immediate goals. He argued that firms should have an elite corps of general managers, who set these long-term objectives, and then a group of more specialised managers. For his critics, this was a retreat from his earlier emphasis on the soft side of management. For Drucker it was all perfectly consistent: if you rely too much on empowerment you risk anarchy, whereas if you rely too much on command-and-control you sacrifice creativity. The trick is for managers to set long-term goals, but then allow their employees to work out ways of achieving those goals. If Drucker helped make management a global industry, he also helped push it beyond its business base. He was emphatically a management thinker, not just a business one. He believed that management is “the defining organ of all modern institutions”, not just corporations.

E There are three persistent criticisms of Drucker’s work. The first is that he focused on big organisations rather than small ones. The Concept of the Corporation was in many ways a fanfare to big organisations. As Drucker said, “We know today that in modern industrial production, particularly in modern mass production, the small unit is not only inefficient, it cannot produce at all.” The book helped to launch the “big organisation boom” that dominated business thinking for the next 20 years. The second criticism is that Drucker’s enthusiasm for management by objectives helped to lead the business down a dead end. They prefer to allow ideas, including ideas for long-term strategies, to bubble up from the bottom and middle of the organisations rather than being imposed from on high. Thirdly, Drucker is criticised for being a maverick who has increasingly been left behind by the increasing rigour of his chosen field. There is no single area of academic management theory that he made his own.

F There is some truth in the first two arguments. Drucker never wrote anything as good as The Concept of the Corporation on entrepreneurial start-ups. Drucker’s work on management by objectives sits uneasily with his earlier and later writings on the importance of knowledge workers and self-directed teams. But the third argument is short-sighted and unfair because it ignores Drucker’s pioneering role in creating the modern profession of management. He produced one of the first systematic studies of a big company. He pioneered the idea that ideas can help galvanise companies. The biggest problem with evaluating Drucker’s influence is that so many of his ideas have passed into conventional wisdom. In other words, he is the victim of his own success. His writings on the importance of knowledge workers and empowerment may sound a little banal today. But they certainly weren’t banal when he first dreamed them up in the 1940s, or when they were first put in to practice in the Anglo-Saxon world in the 1980s. Moreover, Drucker continued to produce new ideas up until his 90s. His work on the management of voluntary organisations remained at the cutting edge.

New Agriculture in Oregon, US

A Onion growers in eastern Oregon are adopting a system that saves water and keeps topsoil in place while producing the highest quality “super-colossal” onions. Pear growers in southern Oregon have reduced their use of some of the most toxic pesticides by up to two-thirds, and are still producing top-quality pear. Range managers throughout the state have controlled the poisonous weed tansy ragwort with insect predators and saved the Oregon livestock industry up to $4.8 million a year.

B These are some of the results Oregon growers have achieved in collaboration with Oregon State University (OSU) researchers as they test new farming methods including integrated pest management (IPM). Nationwide, however, IPM has not delivered results comparable to those in Oregon. A recent U.S General Accounting Office (GAO) report indicates that while integrated pest management can result in dramatically reduced pesticide use, the federal government has been lacking in effectively promoting that goal and implementing IPM. Farmers also blame the government for not making the new options of pest management attractive. “Wholesale changes in the way that farmers control the pests on their farms is an expensive business.” Tony Brown, of the National Farmers Association, says. “If the farmers are given tax breaks to offset the expenditure, then they would willingly accept the new practices.” The report goes on to note that even though the use of the riskiest pesticides has declined nationwide, they still make up more than 40 percent of all pesticides used today; and national pesticide use has risen by 40 million kilograms since 1992. “Our food supply remains the safest and highest quality on Earth but we continue to overdose our farmland with powerful and toxic pesticides and to under-use the safe and effective alternatives,” charged Patrick Leahy, who commissioned the report. Green action groups disagree about the safety issue. “There is no way that habitual consumption of foodstuffs grown using toxic chemical of the nature found on today’s farms can be healthy for consumers,” noted Bill Bowler, spokesman for Green Action, one of many lobbyists interested in this issue.

C The GAO report singles out Oregon’s apple and pear producers who have used the new IPM techniques with growing success. Although Oregon is clearly ahead of the nation, scientists at OSU are taking the Government Accounting Office criticisms seriously. “We must continue to develop effective alternative practices that will reduce environmental hazards and produce high-quality products,” said Paul Jepson, a professor of entomology at OSU and new director of

D OSU’s Integrated Plant Protection Centre (IPPC). The IPPC brings together scientists from OSU’s Agricultural Experiment Station, OSU Extension service, the U.S. Department of Agriculture and Oregon farmers to help develop agricultural systems that will save water and soil, and reduce pesticides. In response to the GAO report, the Centre is putting even more emphasis on integrating research and farming practices to improve Oregon agriculture environmentally and economically.

E “The GAO report criticizes agencies for not clearly communicating the goals of IPM,” said Jepson. “Our challenge is to greatly improve the communication to and from growers, to learn what works and what doesn’t. the work coming from OSU researchers must be adopted in the field and not simply languish in scientific journals.”

F In Oregon, growers and scientists are working together to instigate new practices. For example, a few years ago scientists at OSU’s Malheur Experiment Station began testing a new drip irrigation system to replace old ditches that wasted water and washed soil and fertilizer into streams. The new system cut water and fertilizer use by half kept topsoil in place and protected water quality.

G In addition, the new system produced crops of very large onions, rated “super-colossal” and highly valued by the restaurant industry and food processors. Art Pimms, one of the researchers at Malheur comments: “Growers are finding that when they adopt more environmentally benign practices, they can have excellent results. The new practices benefit the environment and give the growers their success.”

H OSU researcher in Malheur next tested straw mulch and found that it successfully held soil in place and kept the ground moist with less irrigation. In addition, and unexpectedly, the scientists found that the mulched soil created a home for beneficial beetles and spiders that prey on onion thrips – a notorious pest in commercial onion fields – a discovery that could reduce the need for pesticides. “I would never have believed that we could replace the artificial pest controls that we had before and still keep our good results,” commented Steve Black, a commercial onion farmer in Oregon, “but instead we have actually surpassed expectations.”

I OSU researchers throughout the state have been working to reduce dependence on broad-spectrum chemical spays that are toxic to many kinds of organisms, including humans. “Consumers are rightly putting more and more pressure on the industry to change its reliance on chemical pesticides, but they still want a picture-perfect product,” said Rick Hilton, an entomologist at OSU’s Southern Oregon Research and Extension Centre, where researches help pear growers reduce the need for highly toxic pesticides. Picture perfect pears are an important product in Oregon and traditionally they have required lots of chemicals. In recent years, the industry has faced stiff competition from overseas producers, so any new methods that growers adopt must make sense economically as well as environmentally. Hilton is testing a growth regulator that interferes with the molting of codling moth larvae. Another study used pheromone dispensers to disrupt codling moth mating. These and other methods of integrated pest management have allowed pear growers to reduce their use of organophosphates by two-thirds and reduce all other synthetic pesticides by even more and still produce top-quality pears. These and other studies around the state are part of the effort of the IPPC to find alternative farming practices that benefit both the economy and the environment.

Terminated Dinosaur Era

A Day after day, we hear about how anthropogenic development is causing global warming. According to an increasingly vocal minority, however, we should be asking ourselves how much of this is media hype, and how much is based on real evidence. It seems – as so often is the ease – that it depends on which expert you listen to, or which statistics you study.

B Yes, it is true that there is a mass of evidence to indicate that the world is getting warmer, with one of the world’s leading weather predictors stating that air temperatures have frown an increase of just under half a degree Celsius since the beginning of the twentieth century. And while this may not sound like anything worth losing sleep over, the interna­tional press would have us believe that the consequences could be devastating. Other ex­perts, however, are of the opinion that what we are seeing is just part of a natural upward and downward swing that has always been part of the cycle of global weather. An analysis of the views of major meteorologists in the United States showed that less than 20% of them believed that any change in temperature over the last hundred years was our own fault – the rest attributed it to natural cyclical changes.

C There is, of course, no denying that we are still at a very early stage in understanding weather. The effects of such variables as rainfall, cloud formation, the seas and oceans, gases such as methane and ozone, or even solar energy are still not really understood, and therefore the predictions that we make using them cannot always be relied on.

Dr James Hansen, in 19BH, was predicting that the likely effects of global warming would be a raising of the world temperature which would have disastrous consequences for mankind: “a strong cause arid effect relationship between the current climate and human alteration of the at­mosphere”. He has now gone on record as stating that using artificial models of climate as a way of predicting change is all but impossible. In fact, he now believes that, rather than getting hotter, our planet is getting greener as a result of the carbon dioxide increase, with the prospect of increasing vegetation in areas which in recent history have been frozen wastelands.

D In fact, there is some evidence to suggest that as our computer-based weather models have become more sophisticated, the predicted rises In temperature have been cut back. In addi­tion, if we look at the much-reported rise in global temperature over the last century, a close analysis reveals that the lion’s share of that increase, almost three quarters in total, occurred before man began to “poison” his world with industrial processes and the accom­panying greenhouse gas emissions in the second half of the twentieth century.

E So should we pay any attention to those stories that scream out at us from billboards and television news headlines, claiming that man, with his inexhaustible dependence on oil-based machinery and ever more sophisticated forms of transport is creating a nightmare level of greenhouse gas emissions, poisoning his environment and ripping open the ozone layer?

Doubters point to scientific evidence, which can prove that, of all the greenhouse gases, only two per cent come from man-made sources, the rest resulting from natural emissions. Who, then, to believe: the environmentalist exhorting us to leave the car at home, to buy re-usable products packaged in recycled paper and to plant trees in our back yard? Or the sceptics, including, of course, a lot of big businesses who have most to lose, when they tell us that we are making a mountain out of a molehill? And my own opinion? The jury’s still out as for as I am concerned!

Light pollution

A If humans were truly at home under the light of the moon and stars, we would go into darkness happily, the midnight world as visible to us as it is to the vast number of nocturnal species on this planet. Instead, we are diurnal creatures, with eyes adapted to living in the sun’s light. This is a basic evolutionary fact, even though most of us don’t think of ourselves as diurnal beings any more than we think of ourselves as primates or mammals, or Earthlings. Yet it’s the only way to explain what we’ve done to the night: We’ve engineered it to receive us by filling it with light.

B This kind of engineering is no different than damming a river. Its benefits come with consequences—called light pollution—whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky, where it’s not wanted, instead of focusing it downward, where it is. Ill-designed lighting washes out the darkness of night and radically alters the light levels and light rhythms—to which many forms of life, including ourselves, have adapted.

C Now most of humanity lives under intersecting domes of reflected, refracted light, of scattering rays from overlit cities and suburbs, from light-flooded highways and factories. Nearly all of nighttime Europe is a nebula of light, as is most of the United States and all of Japan. In the south Atlantic the glow from a single fishing fleet squid fishermen during their prey with metal halide lamps—can be seen from space, burning brighter, in fact, than Buenos Aires or Rio de Janeiro.

D We’ve lit up the night as if it were an unoccupied country when nothing could be further from the truth. Among mammals alone, the number of nocturnal species is astonishing. Light is a powerful biological force, and in many species, it acts as a magnet, a process being studied by researchers such as Travis Longcore and Catherine Rich, co-founders of the Los Angeles-based Urban Wildlands Group. The effect is so powerful that scientists speak of songbirds and seabirds being “captured” by searchlights on land or by the light from gas flares on marine oil platforms, circling and circling in the thousands until they drop. Migrating at night, birds are apt to collide with brightly lit tall buildings; immature birds on their first journey suffer disproportionately.

E Insects, of course, cluster around streetlights, and feeding at those insect clusters is now ingrained in the lives of many bat species. In some Swiss valleys, the European lesser horseshoe bat began to vanish after streetlights were installed, perhaps because those valleys were suddenly filled with light-feeding pipistrelle bats. Other nocturnal mammals—including desert rodents, fruit bats, opossums, and badgers-forage more cautiously under the permanent full moon of light pollution because they’ve become easier targets for predators.

F Some birds—blackbirds and nightingales, among others—sing at unnatural hours in the presence of artificial light. Scientists have determined that long artificial days— and artificially short nights induce early breeding in a wide range of birds. And because a longer day allows for longer feeding, it can also affect migration schedules. One population of Bewick’s swans wintering in England put on fat more rapidly than usual, priming them to begin their Siberian migration early. The problem, of course, is that migration, like most other aspects of bird behaviour, is a precisely timed biological behaviour. Leaving early may mean arriving too soon for nesting conditions to be right

G Nesting sea turtles, which show a natural predisposition for dark beaches, find fewer and fewer of them to nest on. Their hatchlings, which gravitate toward the brighter, more reflective sea horizon, find themselves confused by artificial lighting behind the beach. In Florida alone, hatchling losses number in the hundreds of thousands every year. Frogs and toads living near brightly lit highways suffer nocturnal light levels that are as much as a million times brighter than normal, throwing nearly every aspect of their behaviour out of joint, including their nighttime breeding choruses.

H Of all the pollution we face, light pollution is perhaps the most easily remedied. Simple changes in lighting design and installation yield immediate changes in the amount of light spilt into the atmosphere and, often, immediate energy savings.

I It was once thought that light pollution only affected astronomers, who need to see the night sky in all its glorious clarity. And, in fact, some of the earliest civic efforts to control light pollution—in Flagstaff, Arizona, half a century ago—were made to protect the view from Lowell Observatory, which sits high above that city. Flagstaff has tightened its regulations since then, and in 2001 it was declared the first International Dark Sky City. By now the effort to control light pollution has spread around the globe. More and more cities and even entire countries, such as the Czech Republic, have committed themselves to reducing unwanted glare.

J Unlike astronomers, most of us may not need an undiminished view of the night sky for our work, but like most other creatures we do need darkness. Darkness is as essential to our biological welfare, to our internal clockwork, as light itself. The regular oscillation of waking and sleep in our lives, one of our circadian rhythms—is nothing less than a biological expression of the regular oscillation of light on Earth. So fundamental are these rhythms to our being that altering them is like altering gravity.

Lighting up the lies

A Last year Sean A. Spence, a professor at the school of medicine at the University of Sheffield in England, performed brain scans that showed that a woman convicted of poisoning a child in her care appeared to be telling the truth when she denied committing the crime. This deception study, along with two others performed by the Sheffield group, was funded by Quickfire Media, a television production company working for the U.K.’s Channel 4, which broadcast videos of the researchers at work as part of a three-part series called “Lie Lab.” The brain study of the woman later appeared in the journal European Psychiatry.

B Functional magnetic resonance imaging (fMRI) purports to detect mendacity by seeing inside the brain instead of tracking peripheral measures of anxiety—such as changes in pulse, blood pressure or respiration —measured by a polygraph. Besides drawing hundreds of thousands of viewers, fMRI has pulled in entrepreneurs. Two companies—Cephos in Pepperell, Mass., and No Lie MRI in Tarzana, Calif.—claim to predict with 90 percent or greater certitude whether you are telling the truth. No Lie MRI, whose name evokes the casual familiarity of a walk-in dental clinic in a strip mall, suggests that the technique may even be used for “risk reduction in dating” .

C Many neuroscientists and legal scholars doubt such claims—and some even question whether brain scans for lie detection will ever be ready for anything but more research on the nature of deception and the brain. An fMRI machine tracks blood flow to activated brain areas. The assumption in lie detection is that the brain must exert extra effort when telling a lie and that the regions that do more work get more blood. Such areas light up in scans; during the lie studies, the illuminated regions are primarily involved in decision making.

D To assess how fMRI and other neurocience findings affect the law, the Mac- Arthur Foundation put up $10 million last year to pilot for three years the Law and Neuroscience Project. Part of the funding will attempt to set criteria for accurate and reliable lie detection using fMRI and other brain-scanning technology. “I think it’s not possible, given the current technology, to trust the results,” says Marcus Raichle, a neuroscientist at the Washington University School of Medicine in St. Louis who heads the project’s study group on lie detection. “But it’s not impossible to set up a research program to determine whether that’s possible.” A major review article last year in the American Journal of Law and Medicine by Henry T. Greely of Stanford University and Judy Illes, now at the University of British Columbia, explores the deficiencies of existing research and what may be needed to move the technology forward. The two scholars found that lie detection studies conducted so far (still less than 20 in all) failed to prove that fMRI is “effective as a lie detector in the real world at any accuracy level.”

E Most studies examined groups, not individuals.Subjects in these studies were healthy young adults—making it unclear how the results would apply to someone who takes a drug that affects blood pressure or has a blockage in an artery. And the two researchers questioned the specificity of the lit-up areas; they noted that the regions also correlate with a wide range of cognitive behaviors, including memory, self- monitoring and conscious self-awareness.

F The biggest challenge for which the Law and Neuroscience Project is already funding new research—is how to diminish the artificiality of the test protocol. Lying about whether a playing card is the seven of spades may not activate the same areas of the cortex as answering a question about whether you robbed the comer store. In fact, the most realistic studies to date may have come from the Lie Lab television programs. The two companies marketing the technology are not waiting for more data. Cephos is offering scans without charge to people who claim they were falsely accused if they meet certain criteria in an effort to get scans accepted by the courts. Allowing scans as legal evidence could open a potentially huge and lucrative market. “We may have to take many shots on goal before we actually see a courtroom,” says Cephos chief executive Steven

Laken. He asserts that the technology has achieved 97 percent accuracy and that the more than 100 people scanned using the Cephos protocol have provided data that have resolved many of the issues that Greely and Illes cited.

G But until formal clinical trials prove that the machines meet safety and effectiveness criteria, Greely and Illes have called for a ban on non-research uses. Trials envisaged for regulatory approval hint at the technical challenges. Actors, professional poker players and sociopaths would be compared against average Joes. The devout would go in the scanner after nonbelievers. Testing would take into account social setting. White lies—“no, dinner really was fantastic”—would have to be compared against untruths about sexual peccadilloes to ensure that the brain reacts identically.

H There potential for abuse prompts caution. “The danger is that people’s lives can be changed in bad ways because of mistakes in the technology,” Greely says. “The danger for the science is that it gets a black eye because of this very high profile use of neuroimaging that goes wrong.” Considering the long and controversial history of the polygraph, gradualism may be the wisest course to follow for a new diagnostic that probes an essential quality governing social interaction.

Carbon Capture and Storage

High coal dependence

Renewable energy is much discussed, but coal still plays the greatest role in the generation of electricity, with recent figures from the International Energy Agency showing that China relies on it for 79% of its power, Australia for 78%, and the US for 45%. Germany has less reliance at 41%, which is also the global average. Furthermore, many countries have large, easily accessible deposits of coal, and numerous highly skilled miners, chemists, and engineers. Meanwhile, 70% of the world’s steel production requires coal, and plastic and rayon are usually coal derivatives.

Currently, coal-fired power plants fed voracious appetites, but they produce carbon dioxide (CO2) in staggering amounts. Urbanites may grumble about an average monthly electricity bill of $113, yet they steadfastly ignore the fact that they are not billed for the 6-7 million metric tons of CO2 their local plant belches out, which contribute to the 44% of global CO2 levels from fossil-fuel emissions. Yet, as skies fill with smog and temperatures soar, people crave clean air and cheap power.

The Intergovernmental Panel on Climate Change that advises the United Nations has testified that the threshold of serious harm to the Earth’s temperature is a mere 2° Celsius above current levels, so it is essential to reduce carbon emissions by 80% over the next 30 years, even as demand for energy will rise by 50%, and one proposal for this is the adoption of carbon capture and storage (CCS).

Underground carbon storage

Currently, CO2 storage, or sequestration as it is known, is practised by the oil and gas industry, where CO2 is pumped into oil fields to maintain pressure and ease extraction – one metric ton dissolves out about three barrels, or separated from natural gas and pumped out of exhausted coal fields or other deep seams. The CO2 remains underground or is channelled into disused sandstone reservoirs. However, the sale of oil and natural gas is profitable, so the $17-per-ton sequestration cost is easily borne. There is also a plan for the injection of CO2 into saline aquifers, 1,000 metres beneath the seabed, to prevent its release into the atmosphere.

Carbon capture

While CO2 storage has been accomplished, its capture from power plants remains largely hypothetical, although CCS plants throughout Western Europe and North America are on the drawing board.

There are three main forms of CCS: pre-combustion, post-combustion, and oxy-firing. In a 2012 paper from the US Congressional Budget Office (CBO), post-combustion capture was viewed most favourably since existing power plants can be retrofitted with it, whereas pre-combustion and oxy-firing mean the construction of entirely new plants. However, pre-combustion and oxy-firing remove more CO2 than post-combustion and generate more electricity.

Post-combustion capture means CO2 is separated from gas after coal is burnt but before electricity is generated, while in oxy-firing, coal is combusted in pure oxygen. In pre-combustion, as in an Integrated Gasification Combined Cycle system (IGCC), oxygen, coal, and water ae burnt together to produce a synthetic gas called Syngas – mainly hydrogen – which drives two sets of turbines, firstly gas-driven ones, then, as the cooling Syngas travel through water, steam-driven ones. Emissions from this process contain around ten percent of the CO2 that burning coal produces.

The pros and cons of CCS

Several countries are keen to scale up CCS as it may reduce carbon emissions quickly, and powerful lobby groups for CCS exist among professionals in mining and engineering. Foundries and refineries that produce steel and emit carbon may also benefit, and the oil and gas industry is interested because power-plant equipment consumes their products. In addition, recent clean energy acts in many countries mandate that a percentage of electricity be generated by renewables or by more energy-efficient systems, like CCS.

As with desalination, where powerful lobbies wield influence, states sometimes find it easier to engage in large projects involving a few players rather than change behaviours on a more scattered household scale. Furthermore, replacing coal with zero-emission photovoltaic (PV) cells to produce solar energy would require covering an area nearly 20,720 square kilometres, roughly twice the size of Lebanon or half of Denmark.

Still, there are many reservations about CCS. Principally, it is enormously expensive: conservative estimates put the electricity it generates at more than five times the current retail price. As consumers are unlikely to want to bear this price hike, massive state subsidies would be necessary for CCS to work.

The capital outlay of purchasing equipment for retrofitting existing power plants is high enough, but the energy needed to capture CO2 means one third more coal must be burnt, and building new CCS plants is at least 75% more expensive than retro-fitting.

Some CCS technology is untried, for example, the Syngas-driven turbines in an IGCC system have not been used on an industrial scale. Post capture, CO2 must be compressed into a supercritical liquid for transport and storage, which is also costly. The Qatar Carbonates and Carbon Storage Research Centre predicts 700 million barrels per day of this liquid would be produced if CCS were adopted modestly. It is worth noting that current oil production is around 85 million barrels per day, so CCS would produce eleven times more waste for burial than oil that was simultaneously being extracted.

Sequestration has been used successfully, but there are limited coal and oil fields where optimal conditions exist. In rock that is too brittle, earthquakes could release the CO2. Moreover, proposals to store CO2 in saline aquifers are just that – proposals: sequestration has never been attempted in aquifers.

Most problematic of all, CCS reduces carbon emissions but does not end them, rendering it a medium-term solution.

Alternatives

There are at least four reasonably-priced alternatives to CCS. Firstly, conventional pulverised coal power plants are undergoing redesign so more electricity can be produced from less coal. Before coal is phased out – as ultimately it will have to be – these plants could be more cost-effective. Secondly, hybrid plants using natural gas and coal could be built. Thirdly, natural gas could be used on its own. Lastly, solar power is fast gaining credibility.

In all this, an agreed measure of cost for electricity generation must be used. This is called a levelized cost of energy (LCOE) – an average cost of producing electricity over the lifetime of a power plant, including construction, financing, and operation, although pollution is not counted. In 2012, the CBO demonstrated that a new CCS plant had an LCOE of about $0.09-0.15 per kilowatt-hour (kWh), but according to the US Energy Information Administration, the LCOE from a conventional natural gas power plant without CCS is $0.0686/kWh, making it the cheapest way to produce clean energy.

Solar power costs are falling rapidly. In 2013, the Los Angeles Department of Water and Power reported that energy via a purchase agreement from a large solar plant was $0.095/kWh, and Greentech Media, a company that reviews environmental projects, found a 2014 New Mexico solar project that generates power for $0.0849/kWh.

Still, while so much coal and so many coal-fired plants exist, decommissioning them all may not be realistic. Whatever happens, the conundrum of cheap power and clean air may remain unsolved for some time.
