Researchers from Harvard University have uncovered a biological mechanism that affects aging greatly. Their study shows that caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating the connections between nerves and the muscles that they control.

The research team was led by professors Joshua Sanes and Jeff Lichtman from the Center for Brain Science at Harvard. Their paper, published online in the journal Proceedings of the National Academy of Sciences, aims to explain previous findings, indicating that exercise and restricted-calorie diets help to stave off the mental and physical degeneration of aging.
