IOL reports that scientists have uncovered another biochemical longevity mechanism in nematode worms. The "TOR" protein is present in plants, animals and humans; it regulates metabolism and energy. By removing it, the life span of nematodes is nearly doubled. Scientists suggest that TOR may be involved in the mechanisms of calorie restriction, which have not yet been fully explored (although people are working on it). Knowledge is power. As science uncovers the mechanisms of longevity, we get closer to developing true anti-aging and healthy life extension therapies.
