BACKGROUND: Peripheral artery disease (PAD) and its severe form, chronic limb-threatening ischemia (CLTI), significantly impair blood flow to the lower extremities, affecting millions of adults ...

Researchers developed a high-sensitivity proteomics method to analyze individual human muscle fibers. The technique identified 37 protein variations, including key contractile proteins and their ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle ...

Researchers found that one key measure of physical fitness may strongly predict longevity later in life, especially among women.

Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to ...

University of Delaware’s Mona Batish is a molecular biologist. She studies circular RNAs formed as a result of so-called molecular mistakes that occur when a strand of RNA — the ribonucleic acid that ...

Combining lab-grown muscle tissue with a series of flexible mechanical joints has led to the development of an artificial hand that can grip and make gestures. The breakthrough shows the way forward ...

During hibernation, brown bears spend up to six months lying almost completely still, without eating, drinking or exercising.
