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

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 ...

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.

A new study suggests severe obesity may weaken heart muscle cells in people with heart failure with preserved ejection ...

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 ...

The study, published in Developmental Cell, further shows that the resting tension in the heart cells is increased after a heart attack and other heart diseases. This changes the way that heart cells ...
