As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the structure ...

We humans need oxygen to breath - for a lot of microbes it is a lethal poison. That is why microorganisms have developed ways to render oxygen molecules harmless. Microbiologists have now succeeded in ...

A new approach reveals unexpected ways oxygen can bind to rare metals. Iron plays a central role in how the body uses oxygen. In hemoglobin, it binds dioxygen, a pair of oxygen atoms, allowing blood ...
