New mechanism found: Researchers discovered that statins can bind to and activate ryanodine receptors in muscle cells, potentially explaining muscle pain in some patients. Why it matters: Uncovering ...

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 ...

Ferulic acid suppresses ileal smooth muscle contraction by inhibiting calcium ion influx through voltage-dependent calcium channels. This action may help prevent or treat excessive intestinal motility ...

Protein builds muscles–but not on its own. That’s the conclusion of a new report from Harvard’s T.H. Chan School of Public ...
