Syringe, Eyewire Athlete cheats seek genetic boost  - BBC  "I would say half the e-mails I get now are from athletes," he told an American science conference in Washington State. "The other half is from patients with muscular dystrophy." Sweeney and colleagues injected their rats with a virus which carried a gene into muscle cells to produce a growth hormone called IGF-I. The rodents given the therapy and put on an exercise programme developed bigger and stronger muscles. While the leap from laboratory animals to human beings is still hypothetical, Lee Sweeney said it was inevitable that athletes and their trainers would attempt to hijack the rat research.
Science closing in on ageing gene  - BBC  Experts believe they are a little nearer to tracking down a gene which may influence how long you live. The relationship between the length of "telomeres" - which lie at the end of strands of DNA called chromosomes inside the nucleus of every cell - and this process, is becoming a little clearer. While the length of these sections are not the only factor governing longevity, other studies have found good reason to suggest a link between the two. A crucial factor in the rate of decrease in telomere length appeared to be exposure to "oxidative stress" - cumulative damage caused by molecules called "free radicals".

Hunt for ancient human molecules  - BBC  Left:  Ancient molecules may give a better idea of what we once looked like.  New technologies may soon allow scientists to identify some of the genes of humankind's oldest ancestors. This raises the possibility of plotting the evolutionary tree of humanity from five million years ago to the present. Professor Hendrik Poinar says DNA fragments should be recoverable from fossils that are a million years old, and proteins from even older times. Professor Poinar, from McMaster University in Canada, said the key was to find fossils preserved so well that samples had not been degraded. DNA, the biomolecule in cells that carries the "code of life", starts to fall apart rapidly under unfavourable conditions. Proteins, on the other hand, which build and maintain the body and are constructed from information in the DNA, are more robust. The oldest protein from a fossil analysed so far was extracted from a bison (Bison priscus) which died 55,000 years ago. But Professor Poinar, who works out of McMaster's department of anthropology, believes we can go back substantially further.
