A new study casts doubt on the theory that oxidative stress shortens lifespan. Researchers have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer. The results contradict the popular theory that production of toxic reactive oxygen species in tissues is responsible for aging.
