Researchers have uncovered an ancient mechanism that retards aging. Drugs that tweaked it could well postpone cancer, diabetes and other diseases of old age. By David Stipp, Scientific American Image: Photographs by Evan Kafka In Brief In 2009 scientists discovered that a drug called rapamycin could significantly extend life span in mice, doing so by interfering with the activity of a protein called mammalian TOR, or mTOR. The finding is the most compelling evidence to date that mammalian aging can be slowed pharmaceuticall ...
