merryprankster writes "New Scientist reports that Scripps Research Institute scientists have found that lowering the body temperature of mice by just 0.5C extends their lifespan by around 15%. Until now the only proven way of increasing longevity has been calorie restriction — but as this also causes a lowering of body temperature the researchers speculate that this cooling may be the underlying mechanism retarding aging. In this study mice with a defect in their lateral hypothalamus, which has the side effect of cooling body temperature, not only lived longer but also ate normal amounts."
