Just like a house, cells need cleaning. In autophagy, a cellular form of housekeeping, debris is collected, broken down, and ...

Repeated exercise, or wasting, can change the way key genes work.

A human heart might contract some three billion times over a lifetime, and each one of those contractions is driven by a protein called myosin. One of three classes of so-called motor proteins in our ...

The production of cultured meat depends on the isolation, expansion, and differentiation of animal stem cells into edible tissues. Muscle stem cells, or satellite cells, are central to this process ...

Sarcopenia—reduced muscle mass, strength, and function—is often associated with aging and frequently impacts quality of life in the elderly. Individuals with sarcopenia are also prone to further ...

Muvon Therapeutics has linked its cell therapy to a 60% drop in stress incontinence episode frequency in a small phase 2 trial, leading the biotech to pitch the candidate as a way to reduce reliance ...

DECEMBER 3, 2025—(BRONX, NY)—Two related studies published today in Nature Metabolism show that a specialized intracellular recycling mechanism—chaperone-mediated autophagy (CMA)—is essential for ...

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 ...

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering ...

The more we move, the more our muscle cells begin to make a memory of that exercise. MIT Technology Review Explains: Let our writers untangle the complex, messy world of technology to help you ...
