Experiments that hint of longer lives: Cynthia Kenyon on TED.com

What controls aging? Biochemist Cynthia Kenyon has found a simple genetic mutation that can double the lifespan of a simple worm, C. Elegans. The lessons from that discovery, and others, are pointing to how we might one day significantly extend youthful human life. (Recorded at TEDGlobal 2011, July 2011, in Edinburg, Scotland. Duration: 16:24)
