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.

In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type ...

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

From the first nerve signal to the final movement, your muscles rely on a complex chain of events involving nerves, proteins, and energy. Actin and myosin filaments slide past each other to create ...

Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

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 ...

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, ...
