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.
Roundworms are elderly and wrinkled at 10 days and by the time they reach two weeks, they're dead. Kenyon found that by masking the DNA's daf-2 gene, her team could extend the roundworms' lives sixfold.
