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.

Muscle cramps are usually blamed on dehydration or low potassium. It’s simple. It’s familiar. And it’s incomplete. The real ...

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 ...

A team of biophysicists set out to tackle the long-standing question about the nature of force generation by myosin, the molecular motor responsible for muscle contraction. The key question they ...

From your morning stretch to your fastest sprint, every movement depends on the precise dance between actin, myosin, and calcium inside your muscle fibers. Scientists are uncovering not only the ...

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, ...

Have you ever wondered about the biochemical mechanisms behind muscle contraction? If the answer is yes, then the (aptly named) Muscle Contraction app is for you! The app reads like an eBook, with ...
