title: Aging: the blurry line between life and death.
abstract: Although historically reactive oxygen species have been implicated as a potential cause of ageing, recent evidence suggests that a modest increase in oxidants can actually extend lifespan. A new study suggests that, in Caenorhabditis elegans, reactive oxygen species regulate longevity through a pathway classically linked to apoptosis.
