The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

Beet juice boosts endurance for many (but not all) people, according to a series of studies over the past five years or so. The active ingredient appears to be nitrate, which somehow reduces the ...

The film discusses the intricate relationship between muscles and bones, highlighting the mechanics of body movement. It explains how muscles work by contracting and relaxing in coordination with ...

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...
