Can we tweak certain genes to stave off the aging process—or, conversely, to speed it up? New research indicates that it may one day be possible.

For the present, the current discovery helps to expalin something that the prevailing theory of aging--the idea that our bodies wear out because of errors accumulating in our DNA--cannot: why different species have different lifespans.

In a triumph for pests, scientists have figured out how to make the fruit fly live longer. But humans still may get something out of the deal. As reported online in Nature Chemical Biology, the discovery that a single protein can inhibit aging holds implications for human longevity and for treatment of some of the world's most feared diseases.
