Researchers have discovered a fountain of youth, in a manner of speaking, for the fruit fly. At first you're probably thinking why on earth would we want longer living flies? The good news is that the researchers were able to extend the lifespan of fruit flies by modifying only one genetic protein, which means inhibiting the aging process in humans may be much simpler than previously thought.

Fruit flies with the modified gene saw 1/3 longer lifespans with no apparent side-effects (although measuring side-effects in a fruit fly can't be easy or very accurate), so if the same were true for humans we could all theoretically live to around the 110-120 yr old range regularly.

Cool or scary? A little of both, I think.
