This image shows dramatically enhanced muscle tissue in a high performing mouse, which has greater numbers of mitochondria (brown), the energy factories of cells. An international team of scientists has created super-strong, high-endurance mice and worms by suppressing a natural muscle-growth inhibitor, suggesting treatments for age-related or genetics-related muscle degeneration are within reach.
