The discovery in the 1990s that a mutation in a single gene of an experimental worm could double its lifespan set off a stampede of research on the molecular biology of aging and triggered hopes that drug therapies or other interventions could be developed to extend healthy human lifespan. But as is often the case in science, the genetic regulation of aging is more complicated than it first appeared.
