Aha! Another Piece Of The Puzzle

Medical News Today reports on new insight into telomeres and a molecule known as RAD51D. From the article: "RAD51D is known to play a role in repairing DNA, but the authors suggest that is has a second role – as supplier of a protective cap for the telomeres." Telomeres are themselves a form of protection and timer, preventing genetic damage, but getting worn away with each cell division. Differences in the activity of RAD51D may cause normal cells to become immortal cancer cells, and it may also play a part in the aging process. This research opens a whole new set of inquiries - the more we learn, the closer we come to being able to effectively fight aging.
