Summary

Many techniques can bestow Methuselah-like life-spans on yeast and other lab creatures: heating their environments, tinkering with their genes, or restricting their food, for example. But the molecular mechanisms that translate these manipulations into longevity remain mysterious. New work suggests that, at least in yeast, a protein whose antiaging powers had been unrecognized until now could explain how diverse stimuli stall aging.
