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 ...
Microvilli are protrusions on the surface of epithelial cells that are dedicated to mechanosensation in the inner ear, and chemosensation and solute uptake in the lungs, gut, intestine and urinary tract. Epithelial cells ...

Some species of Euglenids, a diversified family of aquatic unicellular organisms, can perform large-amplitude, elegantly coordinated body deformations. Although this behavior has been known for centuries, its function is ...
Do bacteria control their "walks" like we do? It might sound strange, but it's a fundamental question. Understanding bacteria motility would not only expand our understanding of their behavior, but would also contribute to ...
