Could mice hold the secret to longer life?
Scientists from the University of Aberdeen, the Aberdeen-based Rowett Research Institute and the Medical Research Council (MRC) in Cambridge have made a major breakthrough in understanding how metabolism affects lifespan. In a 7-year study of mice they found that those with the highest metabolic rate lived the longest, raising the prospect that the effect could be mimicked in humans. Scientists have long thought that a high metabolic rate was linked to a shortened lifespan. The present discovery turns this century old belief on its head and changes dramatically our understanding of the regulation of lifespan. Metabolism is the…
