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 ...

From the microscopic dance of actin and myosin to the full-body power you feel in a workout, muscle contraction is a precise, coordinated process. It starts with a nerve signal, triggers calcium ...

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, ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Our biceps and our brain cells may have more in common than previously thought. New research led by the Lippincott-Schwartz Lab shows that a network of subcellular structures similar to those ...

The next time you train, remember: You’re not just building endurance. You’re upgrading your heart's software. You're ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...
