Tackling Obesity in the Western World

A.  Obesity is a huge problem in many Western countries and one which now attracts considerable medical interest as researchers take up the challenge to find a ‘cure’ for the common condition of being seriously overweight. However, rather than take responsibility for their weight, obese people have often sought solace in the excuse that they have a slow metabolism, a genetic hiccup which sentences more than half the Australian population (63% of men and 47% of women) to a life of battling with their weight. The argument goes like this: it doesn’t matter how little they eat, they gain weight because their bodies break down food and turn it into energy more slowly than those with a so-called normal metabolic rate.

B.  ‘This is nonsense,’ says Dr Susan Jebb from the Dunn Nutrition Unit at Cambridge in England. Despite the persistence of this metabolism myth, science has known for several years that the exact opposite is in fact true. Fat people have faster metabolisms than thin people. ‘What is very clear,’ says Dr Jebb, ‘is that overweight people actually burn off more energy. They have more cells, bigger hearts, bigger lungs and they all need more energy just to keep going.’

C.  It took only one night, spent in a sealed room at the Dunn Unit to disabuse one of their patients of the beliefs of a lifetime: her metabolism was fast, not slow. By sealing the room and measuring the exact amount of oxygen she used, researchers were able to show her that her metabolism was not the culprit. It wasn’t the answer she expected and probably not the one she wanted but she took the news philosophically.

D.  Although the metabolism myth has been completely disproved, science has far from discounted our genes as responsible for making us whatever weight we are, fat or thin. One of the world’s leading obesity researchers, geneticist Professor Stephen O’Rahilly, goes so far as to say we are on the threshold of a complete change in the way we view not only morbid obesity, but also everyday overweight. Prof. O’Rahilly’s groundbreaking work in Cambridge has proven that obesity can be caused by our genes. ‘These people are not weak- willed, slothful or lazy,’ says Prof. O’Rahilly, ‘They have a medical condition due to a genetic defect and that causes them to be obese.’

E.  In Australia, the University of Sydney’s Professor Ian Caterson says while major genetic defects may be rare, many people probably have minor genetic variations that combine to dictate weight and are responsible for things such as how much we eat, the amount of exercise we do and the amount of energy we need. When you add up all these little variations, the result is that some people are genetically predisposed to putting on weight. He says while the fast/slow metabolism debate may have been settled, that doesn’t mean some other subtle change in the metabolism gene won’t be found in overweight people. He is confident that science will, eventually, be able to ‘cure’ some forms of obesity but the only effective way for the vast majority of overweight and obese people to lose weight is a change of diet and an increase in exercise.

F.  Despite the $500 million a year Australians spend trying to lose weight and the $830 million it costs the community in health care, obesity is at epidemic proportions here, as it is in all Western nations. Until recently, research and treatment for obesity had concentrated on behaviour modification, drugs to decrease appetite and surgery. How the drugs worked was often not understood and many caused severe side effects and even death in some patients. Surgery for obesity has also claimed many lives.

G.  It has long been known that a part of the brain called the hypothalamus is responsible for regulating hunger, among other things. But it wasn’t until 1994 that Professor Jeffery Friedman from Rockerfeller University in the US sent science in a new direction by studying an obese mouse. Prof. Friedman found that unlike its thin brothers, the fat mouse did not produce a hitherto unknown hormone called leptin. Manufactured by the fat cells, leptin acts as a messenger, sending signals to the hypothalamus to turn off the appetite. Previously, the fat cells were thought to be responsible simply for storing fat. Prof. Friedman gave the fat mouse leptin and it lost 30% of its body weight in two weeks.

H.  On the other side of the Atlantic, Prof. O’Rahilly read about this research with great excitement. For many months two blood samples had lain in the bottom of his freezer, taken from two extremely obese young cousins. He hired a doctor to develop a test for leptin in human blood, which eventually resulted in the discovery that neither of the children’s blood contained the hormone. When one cousin was given leptin, she lost a stone in weight and Prof. O’Rahilly made medical history. Here was the first proof that a genetic defect could cause obesity in humans. But leptin deficiency turned out to be an extremely rare condition and there is a lot more research to be done before the ‘magic’ cure for obesity is ever found.

Is there more to video games than people realize?

Many people who spend a lot of time playing video games insist that they have helped them in areas like confidence-building, presentation skills and debating. Yet this way of thinking about video games can be found almost nowhere within the mainstream media, which still tend to treat games as an odd mix of the slightly menacing and the alien. This lack of awareness has become increasingly inappropriate, as video games and the culture that surrounds them have become very big business indeed.

Recently, the British government released the Byron report into the effects of electronic media on children. Its conclusions set out a clear, rational basis for exploring the regulation of video games. The ensuing debate, however, has descended into the same old squabbling between partisan factions: the preachers of mental and moral decline, and the innovative game designers. In between are the gamers, busily buying and playing while nonsense is talked over their heads.

Susan Greenfield, renowned neuroscientist, outlines her concerns in a new book. Every individual’s mind is the product of a brain that has been personalized by the sum total of their experiences; with an increasing quantity of our experiences from very early childhood taking place ‘on screen’ rather than in the world, there is potentially a profound shift in the way children’s minds work. She suggests that the fast-paced, second-hand experiences created by video games and the Internet may inculcate a worldview that is less empathetic, more risk-taking and less contemplative than what we tend to think of as healthy.

Greenfield’s prose is full of mixed metaphors and self-contradictions and is perhaps the worst enemy of her attempts to persuade. This is unfortunate, because however much technophiles may snort, she is articulating widely held fears that have a basis in fact. Unlike even their immediate antecedents, the latest electronic media are at once domestic and work-related, their mobility blurring the boundaries between these spaces, and video games are at their forefront. A generational divide has opened that is in many ways more profound than the equivalent shifts associated with radio or television, more alienating for those unfamiliar with new’ technologies, more absorbing for those who are. So how do our lawmakers regulate something that is too fluid to be fully comprehended or controlled?

Adam Martin, a lead programmer for an online games developer, says:’ Computer games teach and people don’t even notice they’re being taught.’ But isn’t the kind of learning that goes on in games rather narrow? ‘A large part of the addictiveness of games does come from the fact that as you play you are mastering a set of challenges. But humanity’s larger understanding of the world comes primarily through communication and experimentation, through answering the question “What if?’ Games excel at teaching this too.’

Steven Johnson’s thesis is not that electronic games constitute a great, popular art, but that the mean level of mass culture has been demanding steadily more intellectual engagement from consumers. Games, he points out, generate satisfaction via the complexity of their virtual worlds, not by their robotic predictability. Testing the nature and limits of the laws of such imaginary worlds has more in common with scientific methods than with a pointless addiction, while the complexity of the problems children encounter within games exceeds that of anything they might find at school.

Greenfield argues that there are ways of thinking that playing video games simply cannot teach. She has a point. We should never forget, for instance, the unique ability of books to engage and expand the human imagination, and to give us the means of more fully expressing our situations in the world. Intriguingly, the video games industry is now growing in ways that have more in common with an old-fashioned world of companionable pastimes than with a cyber future of lonely, isolated obsessives. Games in which friends and relations gather round a console to compete at activities are growing in popularity. The agenda is increasingly being set by the concerns of mainstream consumers – what they consider acceptable for their children, what they want to play at parties and across generations.

These trends embody a familiar but important truth: games are human products, and lie within our control. This doesn’t mean we yet control or understand them fully, but it should remind us that there is nothing inevitable or incomprehensible about them. No matter how deeply it may be felt, instinctive fear is an inappropriate response to technology of any kind.

So far, the dire predictions many traditionalists have made about the ‘death’ of old-fashioned narratives and imaginative thought at the hands of video games cannot be upheld. Television and cinema may be suffering, economically, at the hands of interactive media. But literacy standards have failed to decline. Young people still enjoy sport, going out and listening to music And most research – including a recent $1.5m study funded by the US government – suggests that even pre-teens are not in the habit of blurring game worlds and real worlds.

The sheer pace and scale of the changes we face, however, leave little room for complacency. Richard Battle, a British writer and game researcher, says Times change: accept it; embrace it.’ Just as, today, we have no living memories of a time before radio, we will soon live in a world in which no one living experienced growing up without computers. It is for this reason that we must try to examine what we stand to lose and gain, before it is too late.

High-Tech Crime-Fighting Toots

A.  Crime-fighting technology is getting more sophisticated and rightly so. The police need to be equipped for the 21st century. In Britain, we’ve already got the world’s biggest DNA database. By next year the state will have access to the genetic data of 4.25m people: one British-based person in 14. Hundreds of thousands of those on the database will never have been charged with a crime.

B.  Britain is also reported to have more than £4 million CCTV (closed circuit television) cameras. There is a continuing debate about the effectiveness of CCTV. Some evidence suggests that it is helpful in reducing shoplifting and car crime. It has also been used to successfully identify terrorists and murderers. However, many claim that better lighting is just as effective to prevent crime and that cameras could displace crime. An internal police report said that only one crime was solved for every 1,000 cameras in London in 2007. In short, there is conflicting evidence about the effectiveness of cameras, so it is likely that the debate will continue.

C.  Professor Mike Press, who has spent the past decade studying how design can contribute to crime reduction, said that, in order for CCTV to have any effect, it must be used in a targeted way. For example, a scheme in Manchester records every licence plate at the entrance of a shopping complex and alerts police when one is found to belong to an untaxed or stolen car. This is an effective example of monitoring, he said. Most schemes that simply record city centres continually – often not being watched – do not produce results. CCTV can also have the opposite effect of that intended, by giving citizens a false sense of security and encouraging them to be careless with property and personal safety. Professor Press said: ‘All the evidence suggests that CCTV alone makes no positive impact on crime reduction and prevention at all. The weight of evidence would suggest the investment is more or less a waste of money unless you have lots of other things in place.’ He believes that much of the increase is driven by the marketing efforts of security companies who promote the crime-reducing benefits of their products. He described it as a ‘lazy approach to crime prevention’ and said that authorities should instead be focusing on how to alter the environment to reduce crime.

D.  But in reality, this is not what is happening. Instead, police are considering using more technology. Police forces have recently begun experimenting with cameras in their helmets. The footage wilt be stored on police computers, along with the footage from thousands of CCTV cameras and millions of pictures from numberplate recognition cameras used increasingly to check up on motorists.

E.  And now another type of technology is being introduced. It’s called the Microdrone and it’s a toy-sized remote-control craft that hovers above streets or crowds to film what’s going on beneath. The Microdrone has already been used to monitor rock festivals, but its supplier has also been in discussions to supply it to the Metropolitan Police, and Soca, the Serious Organised Crime Agency. The drones are small enough to be unnoticed by people on the ground when they are flying at 350ft. They contain high-resolution video surveillance equipment and an infrared night vision capability, so even in darkness they give their operators a bird’s-eye view of locations while remaining virtually undetectable.

F.  The worrying thing is, who will get access to this technology? Merseyside police are already employing two of the devices as part of a pilot scheme to watch football crowds and city parks looking for antisocial behaviour. It is not just about crime detection: West Midlands fire brigade is about to lease a drone, for example, to get a better view of fire and flood scenes and aid rescue attempts; the Environment Agency is considering their use for monitoring of illegal fly tipping and oil spills. The company that makes the drone says it has no plans to License the equipment to individuals or private companies, which hopefully will prevent private security firms from getting their hands on them. But what about local authorities? In theory, this technology could be used against motorists. And where will the surveillance society end? Already there are plans to introduce ‘smart water’ containing a unique DNA code identifier that when sprayed on a suspect will cling to their clothes and skin and allow officers to identify them later. As long as high-tech tools are being used in the fight against crime and terrorism, fine. But if it’s another weapon to be used to invade our privacy then we don’t want it.

Glossary:
drone: a remote-controlled pilotless aircraft
350ft: about 107 meters
bird’s eye view: a view from above
fly-tipping: illegally dumping waste (British English)

NTROPY

How a 20-year-old idea eventually became a moneyspinner

A.  The story of how games designer Paul Wickens achieved success with his bestselling game Ntropy is an object lesson to those who want to strike out on their own. Firstly, there’s no need to rush. ‘I had the idea for what ended up as Ntropy – which, by the way, is a play on the word entropy, meaning chaos or disorganisation – about 20 years ago‘, says Mr Wickens. ‘I was building structures with matchsticks while waiting for some friends in a bar. Later I made a scaled-up version of a box of matches, which we used to play with at college for hours on end’.

B.  After leaving college, Mr Wickens, though interested in starting his own company and having designed another couple of games by then, took the safety-first route. ‘I got a job in IT as a programmer’, he recalls. ‘Later I moved into sales support in specific applications, mostly centred round e-commerce. For the most part I forgot about my games’. So what reawakened his interest? ‘It was about two years ago’, says Mr Wickens, ‘and there was a downturn in the IT industry. Several of my friends and even colleagues lost their jobs and a couple of them started their own companies. And yes, I suppose I did re-evaluate in the way you do when you think: “What would I do if I were made redundant?”’

C.  What most people don’t do is try to crack the £2 billion-a-year UK toy and games market. ‘I chose Ntropy’, he explains, ‘because it involves all the family. I wrote to several of the big games companies with a brief outline of my game and received the polite “Thanks, but no thanks” reply’. It is at this point, says Mr Wickens, that he began to think seriously about going it alone as an independent. ‘OK, I knew nothing about the UK toy market but I had a lot more general business experience than I did when I left college’.

D.  The next step was to make a full replica of the game, mostly in his workshop – a converted garage at home. ‘Then I had to test it. My father helped here because he works at an outdoor centre. He gave it to people who had no idea who I was. I figured I had to get third parties to assess it and listen to what they had to say’. The result was a return to the workshop for ‘a fairly drastic redesign and some rule changes’.

E.  Nevertheless, the designer was convinced by now that Ntropy had commercial potential. The next question was: ‘Am I prepared to spend what it takes for the next stage of development?’ On the money side, Mr Wickens says it represented his savings over 20 years and remortgaging his house. He set up a company, Tadpole Games – friends helped with the design and Logo for the firm and the game box – and he registered with the UK Patent Office at a cost of £4,000.

F.  The next stage was to design the plastic base on which the stick structure could be built. Mr Wickens says: ‘A friend came up with the design and a firm I found used this very futuristic process called Selective Laser Sintering to produce the first mould. I kept the different parts of the project separate to protect it’.

G.  Each Ntropy game consists of 64 identical sticks. ‘I could only have done this with the help of the Internet’, he says. ‘I spent weekend after weekend looking for a sustainable source of timber. In the end I found a firm in southern Thailand which used wood from rubber trees and could do it for about 20p a stick. It was also through the Net that I learned about letters of credit and shipping cargo on boats’.

H.  After an anxious six-week wait, the container arrived. ‘I think it was a shock to my neighbours’, says Mr Wickens. ‘There were 700 boxes with 300,000 sticks. I checked some samples and they were the right size. I was overjoyed’. Too soon. ‘Over the next few days I went through the other boxes and found around half of them weren’t the exact size I needed. It’s the first really big lesson I’ve learned. Never do a deal like this without going and checking it out first’.

I.  Mr Wickens formally launched Ntropy to the trade at the London by Fair. Then a stroke of luck, essential to all budding entrepreneurs, came his way. As he tells it: ‘I gave the game to a friend who was meeting some mates in the pub. They played and really enjoyed it. My friend rang the next day to tell me and added: “Oh, by the way, they work at Hamleys.”’ Hamleys is London’s top toy shop. ‘Then their boss rang me to say, despite one or two concerns, “We like it, so let’s give it a go.”’ The rest, as they say, is history. Ntropy took off and the first batch of 2,500 moved fast.

J.  And the future? ‘I’ve just taken on someone to develop the commercial side of Tadpole’, says Mr Wickens. ‘If that works out, he will take a stake in the business. I want Ntropy to be a global product but I don’t necessarily see myself as an out-and-out businessman. I already have another couple of games I’d like to develop’.

A.  Popular interest in Mars, the ‘Red Planet’, is long-established, but has enjoyed two dramatic flowerings, one in the 1890s and the other a century later.

B.  Any speculation about life on Mars, then or now, is part of a long discussion on ‘the plurality of worlds’. Pluralists believe that there are other worlds apart from ours which contain life — an idea that had its origins in classical Greece. In the 19th century, the new science of astrophysics suggested that large numbers of stars in the sky were similar to the sun in their composition — perhaps they too were circled by planetary systems. Nearer to home Mars, our neighbour in the solar system, seemed to offer the evidence the pluralists had lacked until then.

C.  The characteristics of Mars’ orbit are such that its distance from Earth varies considerably — from 34.5 to 234.5 million miles. From an astronomer’s standpoint it was particularly well-placed for observation in 1877, 1892 and 1909. Observations in each of these years intensified discussion about possible life on Mars.

D.  If life, intelligent or otherwise, were to be found on Mars then life on Earth would not be unique. The scientific, theological and cultural outcomes of such a discovery could be stupendous. In 1859, Fr. Angelo Secchi, director of the Vatican observatory and a confirmed pluralist, observed markings on the surface of Mars which he described as canali, ‘channels’. The fateful word had been launched on its career, although there was little immediate development from Secchi’s work.

E.  In 1877 another Italian, Giovanni Schiaparelli, one of Europe’s most distinguished astronomers, also observed the canali, but he added the refinement that they appeared to be constituents of a system. Other astronomers observed features that might he continents or seas; Schiaparelli confirmed these findings and gave them finely sonorous classical names such as Hellas, Mare Etythraeum, Promethei Sinus.

F.  Although Schiaparelli was cautious in his public statements, recent research suggests that he was a pluralist. Certainly his choice of familiar place names for the planet, and his publicising of the calla network, encouraged pluralist speculation. Inevitably, cumuli was soon being translated into English as ‘canals’ rather than ‘channels’. In 1882 Schiaparelli further fuelled speculation by discovering twin canals; a configuration which he named ‘gemination’; he described no fewer than sixty canals and twenty geminations.

G.  Some of Schiaparellrs findings were confirmed by the astronomers Perrotin and Thollon at Nice Observatory in 1886. In 1888, however, Perrotin confused matters by announcing that the Martian continent of ‘Libya’ observed by Schiaparelli in 1886 ‘no longer exists today’. The confusion grew; two prestigious observatories in the US found in one case no canals, in another a few of them but no geminations, and no changes to Libya.

H.  While the observers exchanged reports and papers, the popularisers got to work. They were generally restrained at first. The British commentator Richard Proctor thought that the canals might be rivers; he was among the first to suggest that a Martian canal would have to be ‘fifteen or twenty miles broad’ to be seen from Earth. The leading French pluralist, Camille Flammarion, published his definitive La Planete Mars in 1892: ‘the canals may be due … to the rectification of old rivers by the inhabitants for the purpose of the general distribution of water …’. Other commentators supposed the ‘canals’ might be an optical illusion, a line first advanced by the English artist Nathaniel Green, teacher of painting to Queen Victoria and an amateur astronomer.

I.  The canals debate might have levelled off at this point had it not been for the incursion of its most prominent controversialist — and convinced pluralist — Percival Lowell. Lowell, an eminent Bostonian, entered the astronomical argument after a career in business and diplomacy, mainly in the Orient. He may not have brought an entirely objective mind to the task. Even before he started observing he had announced that the canals were probably ‘the work of some sort of intelligent beings’.

J.  The newly-arrived popular press was very willing to report Lowell’s findings and views; canal mania grew apace. By 1910 Lowell had reported over 400 canals with.an average length of 1,500 miles. He wrote plausibly about the Martian atmosphere and the means by which the canals distributed water from Mars polar caps to irrigate the planet before evaporation returned moisture to the poles. This water cycle appealed to popular evolutionism which perceived Mars as an old, dying world trying to avert its fate by rational and large-scale engineering — this was, after all, an age of great canals: Panama, Dortmund-Ems, Manchester, Corinth.

You are what you speak

Does your mother tongue really affect the way you see the world?

Does the language you speak influence the way you think? Does it help define your world view? Anyone who has tried to master a foreign tongue has at least thought about the possibility.

At first glance the idea seems perfectly plausible. Conveying even simple messages requires that you make completely different observations depending on your language. Imagine being asked to count some pens on a table. As an English speaker, you only have to count them and give the number. But a Russian may need to consider the gender and a Japanese speaker has to take into account their shape (long and cylindrical) as well, and use the number word designated for items of that shape.

On the other hand, surely pens are just pens, no matter what your language compels you to specify about them? Little linguistic peculiarities, though amusing, don’t change the objective world we are describing. So how can they alter the way we think?

Scientists and philosophers have been grappling with this thorny question for centuries. There have always been those who argue that our picture of the Universe depends on our native tongue. Since the 1960s, however, with the ascent of thinkers like Noam Chomsky, and a host of cognitive scientists, the consensus has been that linguistic differences don’t really matter, that language is a universal human trait, and that our ability to talk to one another owes more to our shared genetics than to our varying cultures. But now the pendulum is beginning to swing the other way as psychologists re-examine the question.

A new generation of scientists is not convinced that language is innate and hard-wired into our brain and they say that small, even apparently insignificant differences between languages do affect the way speakers perceive the world. ‘The brain is shaped by experience,’ says Dan Slobin of the University of California at Berkeley. ‘Some people argue that language just changes what you attend to,’ says Lera Boroditsky of the Massachusetts Institute of Technology. ‘But what you attend to changes what you encode and remember.’ In short, it changes how you think.

To start with the simplest and perhaps subtlest example, preparing to say something in a particular language demands that you pay attention to certain things and ignore others. In Korean, for instance, simply to say ‘hello’ you need to know if you’re older or younger than the person you’re addressing. Spanish speakers have to decide whether they are on intimate enough terms to call someone by the informal tu rather than the formal Usted. In Japanese, simply deciding which form of the word ‘I’ to use demands complex calculations involving things such as your gender, their gender and your relative status. Slobin argues that this process can have a huge impact on what we deem important and, ultimately, how we think about the world.

Whether your language places an emphasis on an object’s shape, substance or function also seems to affect your relationship with the world, according to John Lucy, a researcher at the Max Planck Institute of Psycholinguistics in the Netherlands. He has compared American English with Yucatec Maya, spoken in Mexico’s Yucatan Peninsula. Among the many differences between the two languages is the way objects are classified. In English, shape is implicit in many nouns. We think in terms of discrete objects, and it is only when we want to quantify amorphous things like sugar that we employ units such as ‘cube’ or ‘cup’. But in Yucatec, objects tend to be defined by separate words that describe shape. So, for example, ‘long banana’ describes the fruit, while ‘flat banana’ means the ‘banana leaf’ and ‘seated banana’ is the ‘banana tree’.

To find out if this classification system has any far-reaching effects on how people think, Lucy asked English- and Yucatec-speaking volunteers to do a likeness task. In one experiment, he gave them three combs and asked which two were most alike. One was plastic with a handle, another wooden with a handle, the third plastic without a handle. English speakers thought the combs with handles were more alike, but Yucatec speakers felt the two plastic combs were. In another test, Lucy used a plastic box, a cardboard box and a piece of cardboard. The Americans thought the two boxes belonged together, whereas the Mayans chose the two cardboard items. In other words, Americans focused on form, while the Mayans focused on substance.

Despite some criticism of his findings, Lucy points to his studies indicating that, at about the age of eight, differences begin to emerge that reflect language. ‘Everyone comes with the same possibilities,’ he says, ‘but there’s a tendency to make the world fi t into our linguistic categories.’ Boroditsky agrees, arguing that even artificial classification systems, such as gender, can be important.

Nevertheless, the general consensus is that while the experiments done by Lucy, Boroditsky and others may be intriguing, they are not compelling enough to shift the orthodox view that language does not have a strong bearing on thought or perception. The classic example used by Chomskians to back this up is colour. Over the years many researchers have tried to discover whether linguistic differences in categorising colours lead to differences in perceiving them. Colours, after all, fall on a continuous spectrum, so we shouldn’t be surprised if one person’s ‘red’ is another person’s ‘orange’. Yet most studies suggest that people agree on where the boundaries are, regardless of the colour terms used in their own language.
