Researchers developed a way to help people with amputation or paralysis regain limb control. Their optogenetic technique could offer more precise control over muscle contraction, along with a dramatic ...

MIT researchers have developed a way to help people with amputation or paralysis regain limb control. Instead of using electricity to stimulate muscles, they used light. Here, Guillermo Herrera-Arcos ...

An investigation on the International Space Station to learn more about exactly how cells sense gravity could help scientists figure out ways to prevent that muscle loss, in space and on Earth People ...

Building muscles: Muscle stem cells (their nuclei marked in blue) gradually alter their structure and function, becoming adult muscle cells (whose nuclei turn red). Those cells will eventually fuse ...

Muscle function loss occurs when your muscles don’t work or move normally. Complete muscle function loss, or paralysis, involves being unable to contract your muscles normally. If your muscles lose ...
