Enzymes are often described as molecular machines that recognize and process specific molecules. However, they are not rigid structures. Their shapes can change, affecting how molecules enter, ...

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they ...

For nearly half a century, chemists have marveled at azobenzene, a molecule that can be flipped between two distinct shapes simply by shining light on it. Yet one of the most fundamental questions ...
