Calcium pump motions captured in action

The pumping action of the calcium pump protein—an intricate molecular machine with several moving parts that helps control muscle contraction—has been detailed with exquisite precision by RIKEN biophysicists. By providing ...

Integrated photonics meets electron microscopy

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics—circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes ...

E-waste recycling emits emerging synthetic antioxidants

Manufacturers add synthetic antioxidants to plastics, rubbers and other polymers to make them last longer. However, the health effects of these compounds, and how readily they migrate into the environment, are largely unknown. ...

Can defects turn inert materials into useful, active ones?

Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class of catalysts with a wide range of applications, according ...

A brief history of minimal surfaces and the ants that love them

Consider a soap bubble. The way it contains the minimal possible surface area is surprisingly efficient. This is not a trivial issue. Mathematicians have been looking for better ways to calculate minimal surfaces for hundreds ...
