So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

Water molecules on the surface of an electrode flip just before they give up electrons to form oxygen – a feat of nanoscale gymnastics that explains why the reaction takes more energy than it ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

The aurora borealis lit up the night sky in Michigan on Monday and Tuesday, according to the NOAA's Space Weather Prediction Center. Here's a look at what people shared online: The northern lights are ...
