Quirk writes "The Science section of The Guardian is reporting on recent experiments by geneticists 'to unlock the secrets of the aging process has created organisms that live six times their usual lifespan, raising hopes that it might be possible to slow ageing in humans.' 'In the experiment, Dr Longo's team took yeast cells and knocked out two key genes, named Sir2 and SCH9. The latter governs the cells' ability to convert nutrients into energy. They found that instead of dying after a week, the cells lived for up to six weeks.''Research has now begun to test whether the effect works in mice.' So it looks like we might soon have near immortal, fearless mice."
