For the first time, researchers have captured nanoscale video footage of hydrogen and oxygen atoms combining into water out of "thin air" — thanks to a rare metal catalyst. The super-efficient ...

But until now the elusive substance has been almost impossible to analyse because its atoms move around so much. Now scientists have a workaround - freezing it with lasers. "Physicists are in love ...

This paper examines the mechanism of signal transmission through the histidine kinase PhoQ. The paper nicely describes a model of signaling by allosteric coupling between individual domains rather ...
