Studying a cell's crawling motion in a fluid

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 ...

Investigating the motility of swimming Euglena

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 ...

Unusual mutation causes defective sperm in boars

ETH researchers have found a gene mutation that causes the sperm of boars to immobilize. Their discovery will help pig breeders to exclude animals with this genetic defect from breeding in future.

Researchers find how cells move while avoiding adhesion

Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms of this relationship have remained elusive for decades. Now, researchers from the Max Delbrück ...

Frozen: Cutting-edge technology reveals structures within cells

Temperatures of -196 degrees Celsius enable high-resolution imaging of the cell's interior. Researchers at the Institute of Science and Technology (IST) Austria are thus able to show for the first time how the active form ...

Watch how cells squeeze through channels

Observations of cells moving through small channels shed new light on cell migration in 3-D environments, researchers report October 6 in Biophysical Journal. The findings also reveal how cancer cells may penetrate tissues ...
