Research explains action of drug that may slow aging, related disease

A proven approach to slow the aging process is dietary restriction, but new research helps explain the action of a drug that appears to mimic that process -- rapamycin. The advance moves science closer to a compound that might slow aging and reduce age-related disease. The lead researcher said that this study "could provide a way not only to increase lifespan but to address some age-related diseases and improve general health."
