The myosin super-relaxed (SRX) state is a biochemical and structural conformation of myosin that modulates contractility and energy expenditure and is in equilibrium with the disordered relaxed (DRX) ...

Skeletal muscle is a highly heterogeneous tissue, and its contractile proteins are composed of different isoforms, forming various types of muscle fiber, each of which has its own metabolic ...

Engineers developed a method to grow artificial muscle tissue that twitches and flexes in multiple, coordinated directions. These tissues could be useful for building 'biohybrid' robots powered by ...
