How to Improve on Bolt's Performance

You might think after Usain Bolt’s almost superhuman performances in the 100 and 200 m that the war on doping has been won. However winning one battle is not winning the war. As the example of Lyudmila Blonska shows, doping is still occurring. It is almost certain that there are other medals and world records that were achieved by athletes who were doping but were not caught. The sophistication  of the technology means that just because we are picking up fewer positive tests, it does not mean that there are fewer athletes doping

Silicon dreams: digital drugs and regulation

A new worry has hit parents: digital drugs. The idea is that sounds can affect brain states, so by listening to the right kind of sounds desired brain states can be induced - relaxation, concentration, happiness, PMS relief or why not hallucinations? Apparently "idosers" walk around high on sound. Just the right thing for a summer moral panic - kids, computers, drugs and pseudoscience.

How to Win the War on Drugs in Sport

Drug scandals again tarnish the Tour de France. Last week three riders, Spaniards Manuel Beltrain and Moises Duenas and Italian climber Riccardo Ricco, winner of two mountain stages, failed tests for the banned performance enhancer EPO. This year has seen fewer spectacular expulsions, but of course the game is not over.

Does this mean the drug testers are winning the war on drugs? It might. But it might also mean that cyclists and their doctors are getting better at evading testing. A recent BBC investigation supports the latter conclusion. WADA labs have been proven to fail to pick up positive results. There are 80 copy-cat drugs, produced in China, India and Cuba, which are difficult to detect. And labs apparently collude with doctors to “exchange knowledge” on testing procedures. Expert Professor Bengt Saltin, a leading anti-doping expert and a former winner of the IOC Olympic Prize, the highest honour in sports science, said

"I would think that most of the medal winners and many in the finals of endurance events - there is a big risk for them having used EPO."

So despite the numbers of athletes being prosecuted for EPO declining by two-thirds between 2003 and 2006, Professor Saltin concluded this was due to evasion, not a reduction in use.

"The reason that I am still a little bit upset with the whole situation is that I have seen too many suspicious samples that are clearly abnormal. Athletes are getting away with it. Look how many have been caught for EPO misuse recently."

The response is predictable: widen testing critieria. Experts have suggested that urine samples should be tested for any evidence of naturally produced EPO. If there is none, it should be classed as suspicious because the use of artificial EPO for doping causes the body's own production to shut down. These experts also call for testing of blood profiles as well as the urine. An analysis of the number of young red blood cells can also indicate doping.

Is this a solution? No. It will simply escalate the war to the next level. History has proven the ability of athletes and their doctors to ingeniously evade detection. We will never win the war on doping.

What’s wrong with the hermaphrodite world?

Making headlines last week, Melbourne bioethicist Rob Sparrow argued that in order to create the best future for their children, parents should select only girl children or hermaphrodites. He imagined a  “post-sex” world in which males are no longer conceived, and women use frozen sperm, or artificial gametes to reproduce.

Same species, different needs: could 'genes for' improve the way we treat animals?

The New Scientist recently reviewed a variety of studies showing that many traits often supposed unique to humans are in fact shared by animals. There is evidence that apes, dolphins, songbirds, elephants, and monkeys share with humans some of the most important aspects of behaviour associated with speech; killer whales have distinct cultural groups; great apes and some monkeys have a degree of understanding of the minds of others, enabling them to deceive; chimpanzees, gorillas, and crows use tools; and there is suggestive evidence that elephants, magpies, baboons, whales, and chimpanzees demonstrate emotional behaviour, and that monkeys and rats are capable of drawing primitive moral distinctions.

Claims that animals have capacities usually thought unique to humans are controversial, and those who make them are often accused of anthropomorphising animal behaviour. Plausibly, there is often more to such accusations than concern for explanatory parsimony. As humans, we profit from using animals—for food, research, sport, and so on—in ways that we would not use other humans, and suggestions that animals are more like humans than we usually suppose place an unwelcome demand on society to rethink its ethical stance towards animals. This suggests that a clear division between humans and other species is important to us in justifying the discrepancies between what we view as ethical treatment of other humans and what we view as ethical treatment of non-human animals. Pragmatically speaking, if we humans wish to retain a privileged moral status, and if our privileged moral status is at least partly due to our being different to other animals in certain important (usually biologically-based) respects, then it is in our interests to resist attempts to draw similarities between humans and other animals.

Brain Boosting and Cheating in Exams: Four Responses

A report by the Academy of Medical Sciences looking at different aspects of drug use and mental health has identified a growing trend for off-label use of drugs intended for the treatment of diseases including narcolepsy, ADHD and Alzheimer’s. The use of such drugs by a healthy individual can improve memory, alertness and concentration. While the report does not condemn the practice, it raises a number of potential concerns over safety, and fairness. Professor Les Iversen, report co-author, highlighted concerns that the use of enhancement in exams would unfairly advantage wealthier students, and suggested that the use of such drugs could be considered cheating. The report recommends that legislation is prepared to tackle the misuse of such drugs, including the potential for urine testing in schools and universities.

Below are responses from Julian Savulescu, Nick Bostrom, Anders Sandberg and Mark Sheehan on the effects of cognitive enhancing drugs, and the issue of cheating

Humane Evolution

Professor John Harris wonders Who’s afraid of a synthetic human? in the Times. He argues we should support the Human Fertilisation and Embryology Bill because it will help us develop effective therapies and enhance ourselves. Science is about bettering our lot, after all. In particular, he says, synthetic biology may help us avoid going extinct due to our vulnerabilities and instead enable us to choose (or become) our successors as a species.

Many people become confused by the possibility of a posthuman future. The traditional view of the future is a stark one: either humanity extinct, or humans roughly as they are today. The posthuman options would be that we either change ourselves so radically that the resulting species is so  fundamentally different from humanity that we would regard it as something entirely new, or that we create some kind of independent beings that continue our culture even as traditional humanity retires from the forefront (hopefully as proud parents of the new beings). The range of possible options within these scenarios is endless, inviting equally endless and loud speculation. That tends to distract from the key message of Harris’ essay: we are leaving the realm of natural evolution and entering what he calls a realm of enhancement evolution.

A Second Human Singularity?

New Scientist reports this week claims that the reason human cognitive powers are so superior to those of other animals has to do not with biology alone, but also with our ability to interact with others and with the world.

Ban Cosmetic Surgery in Children?

The Queensland Government, in Australia, has announced it will ban cosmetic surgery in people under 18 years of age. Other states, such as New South Wales, have stated they will also consider restricting access by teenagers to cosmetic enhancement.

This is problematic in a number of ways.

Trading on Testosterone: Doping and the Financial Markets

Two cambridge researchers have found that  found that the amount of money a male financial trader makes in a day is correlated with his testosterone level. The pair - John Coates and Joe Herbert - also found that a trader's testosterone at the beginning of a day is strongly predictive of his success that day, suggesting that testosterone causes improved stock market performance, rather than the reverse.
