Muscle Clocks Play a Role in Regulating Metabolism

Diana Kwon | Sep 1, 2018

Just 20 years ago, scientists didn’t even realize muscles had their own circadian clocks. Now they are beginning to appreciate their importance in health.

How Muscles Age, and How Exercise Can Slow It

Gillian Butler-Browne, Vincent Mouly, Anne Bigot, Capucine Trollet | Sep 1, 2018

Researchers untangle the multifarious nature of muscle aging. So far, the only reliable treatment is exercise.
