From arthritis and heart failure to diabetes and menopause, many conditions are associated with muscle weakness and increased fat deposits. Now a multidisciplinary team of researchers at the ...

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 ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

The contraction process involves interactions between actin and myosin filaments within the sarcomeres to generate force. News organizations may use or redistribute this image, with proper attribution ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned structure of animal skeletal muscle, producing materials that resist ...

Recent research from the University of Houston College of Pharmacy identifies key mechanisms of skeletal muscle regeneration and growth of muscles following resistance exercise. It's a finding that ...

Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that ...

Researchers identified a molecular pathway that can limit muscle repair, a finding that may guide future muscular dystrophy treatments.
