Muscle-on-chip systems are three-dimensional human muscle cell bundles cultured on collagen scaffolds. A Stanford University research team sent some of these systems to the International Space Station ...

Musculoskeletal disorders are a primary cause of disability worldwide, especially in aging societies like Japan. As individuals age, reductions in muscle mass and physical activity weaken the body's ...

I’ve always been bookish. I spend most of my time in the lab rather than running, jumping or climbing. But I still have super strong muscles. They’re way bigger than when I was a young. I asked my ...

A new study reveals that vesicles packed with healthy mitochondria can supercharge tissue repair and combat chronic disease, paving the way for next-generation regenerative treatments. Study: ...

When bones break and there is extreme tissue loss--such as after a car accident or a battlefield injury--current treatments don't often lead to effective healing. But certain stem cells from skeletal ...

Researchers from the University of Southern Denmark investigated how eight weeks of high-intensity interval training affect the structure of mitochondria—the parts of muscle cells that produce energy.

A recent study suggests that these microbes may also influence an important aspect of fitness – muscle strength. Muscle strength is a crucial feature of health for many reasons. It supports our joints ...

Statins have been transformative for many individuals, by lowering cholesterol and reducing the risk of heart problems and stroke. But statins can also cause muscle weakness and pain and in some cases ...
