Latest news from Britain: Researchers have reinforced the claim that resveratrol - an ingredient in red wine - could be the key to a longer life. The new study appears to offer vindication for an approach to anti-aging drugs that has been at the centre of heated scientific debate in recent years.

The new findings show for the first time that the metabolic benefits of the red wine compound known as resveratrol evaporate in mice that lack the famed longevity gene SIRT1.

"Resveratrol improves the health of mice on a high-fat diet and increases life span," said David Sinclair of Harvard Medical School. The question was how.

Resveratrol is a dirty molecule, he explained. Its benefits had been attributed largely to its actions on SIRT1, based on studies in yeast, worms, and flies, but the naturally occurring ingredient has other effects; it influences dozens of proteins, and some evidence had pointed to the importance of another well-known gene (called AMPK) for resveratrol's metabolic benefits...Read more
