Can a pill keep your DNA young?

Telomeres—repeating DNA sequences at the ends of chromosomes that become shorter with each cell division—have long tantalized biologists seeking to understand and control the aging process. When its telomeres become too short, a cell stops dividing and eventually dies. Stop that process and (just maybe) immortality beckons; hence the frenzy a decade ago when a group of researchers claimed they had figured out how to slow that winding-down. Now a second round of frenzy is under way. After years of research, the first telomere-targeting pills have hit the market, while other treatments are entering clinical trials. Continue reading


Scientists Find Clues to Aging in a Red Wine Ingredient’s Role in Activating a Protein

From the New York Times By NICHOLAS WADE

A new insight into the reason for aging has been gained by scientists trying to understand how resveratrol, a minor ingredient of red wine, improves the health and lifespan of laboratory mice. They believe that the integrity of chromosomes is compromised as people age, and that resveratrol works by activating a protein known as sirtuin that restores the chromosomes to health.
