Resveratrol test produces good results

BOSTON, Nov. 1 (UPI) -- U.S. researchers say feeding middle-aged mice a high-calorie diet with a compound found in red wine improves their health and extends their lifespan.
David Sinclair and colleagues at the Harvard Medical School supplemented the mice diet with the compound resveratrol, a small molecule that has been shown to extend the lifespan of various animals.
That treatment shifted the animals' physiology towards that of mice fed a standard diet; they lived longer than mice on the same high-fat diet without resveratrol, and although they didn't lose any weight, their quality of life also improved.
The researchers said resveratrol-treated mice had healthier livers and better motor coordination.
Sinclair says resveratrol seems to counter various health risks associated with a high-fat diet, but without skimping on the calories. When scaled up, the doses used in the mouse study should be feasible for human consumption, but he said it's not yet clear whether the molecule will yield similar effects in people.
The study appears online in the journal Nature and will be published in print at a later date.

This undated NASA image shows two galaxies that are slowly colliding and possibly, in hundreds of millions of years, only one galaxy will remain. Although it is likely that no stars in the two galaxies will directly collide, the gas, dust and ambient magnetic fields do interact directly. These galaxies, part of the vast Hydra-Centaurus supercluster of galaxies, spans over 100 thousand light-years across and is located about 100 million light-years away.
