Researchers developed a high-sensitivity proteomics method to analyze individual human muscle fibers. The technique identified 37 protein variations, including key contractile proteins and their ...

Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue, Massachusetts Institute of Technology (MIT) and Boston University investigators ...

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 ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

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

At one point or another, we’ve all experienced the unexpected, intense pain of a muscle cramp. Muscle cramps, also known as muscle spasms or charley horses, are the involuntary contraction of muscle ...
