The capability of cells to generate contractile forces originates from the activity of the molecular motor myosin II on its substrate actin filaments. Although the molecular constituents of ...

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, ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

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 ...

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 ...

Hierarchical structure of muscle and activation of thin filaments. In both skeletal and cardiac muscles under a relaxed state, a low intracellular calcium ion concentration is maintained and the ...

Cytokinetics Inc. has identified bicyclic piperazinones with the ability to modulate skeletal muscle contractility reported to be useful for the treatment of amyotrophic lateral sclerosis, spinal ...

Robots intended to work alongside people or operate in confined, unpredictable environments need actuators that can bend, ...

The coronavirus disease (COVID-19) is a respiratory illness that affects the lungs. The most common symptoms associated with the infection include fever, a continuous dry cough, and difficulty ...

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.
