The BBC reports on a gene that may lead to longer lifespans: apparently it's triggered by low-calorie diets (studies have been done on mice, though certain near-anorexic health nuts claim it works on people... when they're not getting osteoporosis and looking like skeletons).

The team found worms that had their pha-4 genes removed showed no enhanced longevity while on the restricted diet.

But they discovered that the opposite experiment - over-expressing levels of pha-4 in the worms - increased longevity when on the restricted diet.

"This is the first gene we have found that is absolutely essential to the longevity response to dietary restriction," explained Dr Dillin.
