Sound waves directed at the abdomen seem like an unlikely tool for improving muscle function.
Older mice with elevated levels of a single protein grew stronger, more energetic, and had healthier bones. Their untreated peers declined as expected.
Critics have warned that GLP-1 drugs strip away more muscle than ordinary dieting. A new study puts that concern in perspective.
Muscle stem cells in older animals struggle to activate. A new study pinpoints the reason: a specific metabolic pathway fueled by glutamine quietly shuts down with age.
Astronauts returning from space look as though they have aged by years. That is not coincidence.
Creatine is usually thought of as a supplement for young athletes. But a new study suggests its real potential may lie in older adults — when combined with a specific type of…
Muscle loss in older age isn’t just about inactivity or poor diet. The junctions where nerves tell muscles to work are quietly deteriorating — and new research suggests targeted light treatment could…
Age-related muscle loss has long been blamed on stem cells that simply wear out over time.
Ghrelin is best known as the hormone that makes you feel hungry. But it also plays a role in how muscles age.
Periodic fasting has been promoted for years as a powerful way to improve metabolism. But how the body actually responds differs sharply between organs.
Ghrelin is best known as the hormone that makes you hungry. Less well known is that it also appears to undermine muscle health as we age.
As people age, they steadily lose muscle mass — and a hormone best known for triggering hunger may be making things worse.
A small group of fish — including tuna and swordfish — can keep their muscles warmer than the surrounding water. In warming oceans, that remarkable ability is becoming a dangerous liability.
Topping up a single supplement helps a little. But what if you also stopped the leaking?
Frailty in older adults — the combination of muscle loss, fatigue, and heightened vulnerability — has no effective treatment.
