Analyzing years of previous research on dietary and pharmaceutical tests on flies and mice, researchers showed that aging interventions can have opposite effects on mortality rates in males versus females. The findings appear consistent with data gathered on humans as well, says John Tower of the USC Dornsife College of Letters, Arts and Sciences and the USC Davis School of Gerontology.
