Recent studies have shown that under the axonal membrane, rings composed of actin filaments give the structure its flexibility. But those studies had not been able to define the precise architecture of these rings. By combining ...

When a muscle is activated, it is the proteins myosin and actin that go to work. Myosin molecules take hold of actin molecules and pull, like rope pulling, in a process that gets energy from the use of the cellular fuel ATP. ...

Cell motility, the spontaneous movement of cells from one location to another, plays a fundamental role in many biological processes, including immune responses and metastasis. Recent physics studies have gathered new evidence ...
A new piece of a difficult puzzle—the nature of memory—fell into place this week with a hint at how brain cells change structure when they learn something.
