Discovery could lead to new drugs to fight Alzheimer's, other neurological diseasesCAMBRIDGE, Mass. — The same molecular mechanism that increases life span through calorie restriction may help boost memory and brainpower, researchers at MIT's Picower Institute for Learning and Memory report in the July 11 issue of Nature. Resveratrol, found in wine, has been touted as a life-span enhancer because it activates a group of enzymes known as sirtuins, which have gained fame in recent years for their ability to slow the aging process. Now MIT researchers report that Sirtuin1 — a protein that in humans is encoded by the...
