It is a sad fact that old age brings diseases. Many may not be life-threatening, but they make life less fun. One such condition is sarcopenia, which causes the loss of muscle mass and strength, and it is the reason why some old people suffer from loss of stamina, difficulty in walking and heavy breathing.

Sadly there is no treatment for the condition, except for exercise, which only becomes more cumbersome with age. Understanding sarcopenia, then, is crucial to developing new therapies. Now, in a paper published in Nature, scientists have identified the mechanism for this irreversible wear and tear of muscles as one ages.
