Why do humans age, when fairly similar creatures (such as turtles) apparently do not? Evolutionary history has determined that individuals thrive for long enough to produce and nurture their offspring. Thereafter, the ageing process involves a slow decline in physiological vigour and an increasing susceptibility to age-related disease. In this web focus, we present the latest research on a molecule that appears to mimic the well-documented lifespan-extending attributes of eating fewer calories. Also featured is a comprehensive archive on ageing research form Nature Publishing Group, from nematodes to humans.
