The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

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 ...

Researchers identified a critical AMPK phosphorylation site that regulates mitochondria, muscle contraction, and sugar ...

Time under tension (TUT) is a weightlifting technique designed to build muscle mass by increasing the time muscles spend activated during an exercise. We cover if it works and what its benefits are.
