New mechanism of force transduction in muscle cells discovered

The ability of cells to sense and respond to their mechanical environment is critical for many cellular processes but the molecular mechanisms underlying cellular mechanosensitivity are still unclear. Researchers at the University ...

Study identifies a 'sensor' that activates cell migration

The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...

New force sensing method reveals how cells sense tissue stiffness

Just as we can feel whether we are lying on a soft blanket or hard rocks, our cells sense whether they are in a soft or rigid mechanical environment. However, the molecular mechanisms underlying cells' ability to detect tissue ...

Geckos are sticky without effort

(Phys.org) —Geckos, found in places with warm climates, have fascinated people for hundreds of years. Scientists have been especially intrigued by these lizards, and have studied a variety of features such as the adhesive ...

Gecko-inspired adhesion is self-cleaning and reliable

Geckos outclass adhesive tapes in one respect: Even after repeated contact with dirt and dust do their feet perfectly adhere to smooth surfaces. Researchers of the KIT and the Carnegie Mellon University, Pittsburgh, have ...

At the nanoscale, graphite can turn friction upside down

(Phys.org)—If you ease up on a pencil, does it slide more easily? Sure. But maybe not if the tip is sharpened down to nanoscale dimensions. A team of researchers at the National Institute of Standards and Technology (NIST) ...

Why spiders do not stick to their own sticky web sites

Researchers at the Smithsonian Tropical Research Institute and University of Costa Rica asked why spiders do not stick to their own sticky webs. Repeating old, widely quoted but poorly documented studies with modern equipment ...
