- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

Physicists from the Universities of Bayreuth and Grenoble have discovered a new mechanism of cell mobility. Their findings challenge the classical dogma that the molecular motor myosin is essential ...

A human heart might contract some three billion times over a lifetime, and each one of those contractions is driven by a protein called myosin. One of three classes of so-called motor proteins in our ...

The population across developed countries is getting older and the associated frailty and debilitation are becoming major health problems. This gradual muscle loss is accelerated by the poor capacity ...
