The Telegraph notes the recent SENS4 conference: "Cranks and crooks have been peddling immortality potions since before the dawn of history. All manner of bizarre antidotes to ageing have been tried, including the drinking of mercury salts and the eating of diced monkey testicles. Immortality, it would seem, has long been inextricably entwined with lunacy. But that may be about to change. Earlier this month, 200 scientists descended on Queens' College Cambridge to discuss ways of radically extending human lifespan - and even achieving immortality. The Strategies for Engineered Negligible Senescence (SENS) conference, drew together researchers from disciplines as diverse as tissue engineering, artificial intelligence, law, demographics and politics. 'Most people fail to understand how fast medical science is advancing in this area,' says the conference organiser Dr Aubrey de Grey, editor-in-chief of the journal Rejuvenation Research and co-founder of the SENS Foundation. 'Conventional medical progress has ensured that a child born today can expect to live 120 to 150 years. I think it's possible for them to live far longer. If we make the right breakthroughs in the next 25 years, then there is a 50:50 chance that people alive today could live to be 1,000 years old."
