A study shows a newfound diversity in how cells talk to the muscle they innervate, revealing that the subclasses of neurons have distinct propensities for change, or 'plasticity'. A new study by MIT ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle ...

Patients with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, lose muscle control as nerve cells or neurons in the brain and spinal cord degenerate and can no longer send ...

The double helix of DNA is one of the most iconic symbols in science. By imitating the structure of this complex genetic molecule we have found a way to make artificial muscle fibers far more powerful ...

"To investigate the mechanisms driving local TDP-43 accumulation, we combined human ALS biopsies, transgenic mouse models, and neuron–muscle co-cultures grown in microfluidic chambers that allow us to ...

Fast-twitch fibers help with explosive movements like sprinting and weight lifting. Genetics and training influence the distribution of fast-twitch and slow-twitch muscle fibers. Doing strength ...

slow-twitch muscle fibers, which move more slowly but help to keep you moving longer fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, ...
