title: TOR and aging: less is more.
abstract: Metabolism and mitochondrial activity are thought to be important determinants of life span. A new study in this issue of Cell Metabolism (Bonawitz et al., 2007) suggests that the TOR pathway controls mitochondrial respiration in yeast and that the harder mitochondria work, the longer yeast live.
