How cells recycle the machinery that drives their motility?

Research groups at University of Helsinki and Institut Jacques Monod, Paris, discovered a new molecular mechanism that promotes cell migration. The discovery sheds light on the mechanisms that drive uncontrolled movement ...

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 ...

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain ...

The tug-of-war at the heart of cellular symmetry

Symmetry and asymmetry are fundamental properties of nature. Seen from above, butterflies have left-right symmetry, while male fiddler crabs show dramatic asymmetry. This is also the case for the fundamental units of life: ...

Advance in understanding actin sheds light on cell function

A tiny chemical modification on one of the most abundant and important proteins in cells, actin, has long been somewhat mysterious, its function not fully understood, but scientists from the Perelman School of Medicine at ...
