A Missing Molecule May Explain Why Muscles Weaken With Age

Restoring just part of a depleted mitochondrial fat began reversing muscle wasting in mice, suggesting a possible route toward treating age-related muscle decline. As muscles weaken with age, they shift toward fibers built for endurance rather than quick, powerful bursts of movement. These slow-twitch fibers contain more mitochondria, the structures that supply cells with energy, [...]
