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 ...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them. Good ...

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in ...

If your fitness goal is to up the ante on endurance, pack more power into your sprint, or supercharge your strength gains in the gym, it’s worth exploring – what are the different muscle fiber types?
