Scientists are rapidly gaining insight into the processes that cause aging and the possibility of reengineering them to extend life. While studying the science of aging from various angles, David Sinclair of Harvard Medical School has found that resveratrol, the molecule long suspected to make red wine healthful, appears to help organisms from yeast to flies live 30 to 60 percent longer. He also has found evidence that resveratrol may ward off the diseases of aging in mice. NOVA scienceNOW follows Sinclair and other scientists honing in on the keys to longevity. Could a simple pill someday be developed to extend the human life span? Turkish subtitles will be added soon.
