Temple researchers uncover mechanism behind calorie restriction and lengthened lifespan

(Temple University Health System) Almost a century ago, scientists discovered that cutting calorie intake could dramatically extend lifespan in certain animal species.

Now, investigators at the Lewis Katz School of Medicine at Temple University have broken past that barrier. The new work has been published online Sept. 14 in Nature Communications.
