Genetic changes that slow aging in roundworms also keep the lowly baker's yeast from going rapidly over the hill, new research shows. Humans have many of these same genes, and drugs targeting them might eventually turn back our own biological clocks.

Aging shouldn't be an evolved trait, with common genes shared by distant species, many scientists once reasoned. Most animals pass on their DNA long before aging takes its toll. And throughout much of life's history, animals were likelier to die ...
