We need to talk: How cells communicate to activate notch

During formation of multi-cellular organisms, cells need to talk to each other to make critical decisions as to what kind of cell to become, as well as when and where to become that cell type. The Notch signaling system allows ...

Discovery of new catalyst promises cheaper, greener drugs

A chemistry team at the University of Toronto has discovered environmentally-friendly iron-based nanoparticle catalysts that work as well as the expensive, toxic, metal-based catalysts that are currently in wide use by the ...

Nanocrystals go bare: Stripping material’s tiny tethers

(PhysOrg.com) -- Researchers with the DOE's Lawrence Berkeley National Laboratory have discovered a universal technique for stripping nanocrystals of tether-like molecules that until now have posed as obstacles for their ...

Chemists reveal the force within you

A new method for visualizing mechanical forces on the surface of a cell, reported in Nature Methods, provides the first detailed view of those forces, as they occur in real-time.

Positioning and pinching slow proton movement in catalyst

Twisting and pinching slow a catalyst's ability to generate energy from hydrogen, according to scientists at Pacific Northwest National Laboratory's Center for Molecular Electrocatalysis. In converting hydrogen to electricity, ...
