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.

Though many people experience muscle twitching, it's often incorrectly identified as a muscle spasm. While both are involuntary contractions of a muscle, muscle spasms and muscle twitching aren't ...

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 ...

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...

Together, these findings suggest that ferulic acid can act as a natural regulator of intestinal motility. By reducing excessive smooth muscle activity, the compound could potentially help calm ...

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 ...
