In 2007, researchers in Europe studied the health effects of resveratrol, a compound found in red wine. Part of the study included testing mice’s endurance by having them run on a treadmill. Here, the mouse on the right was fed resveratrol, while the mouse on the left was untreated. The treated mouse ran longer and harder than its running mate. This year, researchers conducted a study using a new compound, SRT1720, which targets the same pathway as resveratrol. Again, they tested the mice on the treadmill and found that mice fed this compound showed a similar improvement in performance.
