Biochemical Clues To Long Lifespan Revealed: Findings Extend Longevity Research From Yeast And Worms To Mammals

Researchers at Children's Hospital Boston have discovered how two key cellular influences on lifespan work together, providing insights that may help reveal aging mechanisms in humans. The findings extend longevity research from yeast and worms into mammals, and suggest that longer life results, at least in part, from biochemical interactions that boost cells' ability to resist environmental stresses while inhibiting them from committing suicide. The study appears in the February 19th Science Express, the online edition of the journal Science.
