Life on Earth rests on a knife-edge of chemistry that could easily have tipped the other way. As geochemists reconstruct the ...

Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their ...

The new plot twist is that in order to keep enough nitrogen and phosphorus near its surface, a planet has to start out with ...

Ancient enzymes show life’s nitrogen signal stayed unchanged for billions of years, helping scientists read early Earth.

The people at the Smithsonian Institution National Museum of Natural History were nice enough to give a couple members of the Chemistry in Pictures team a behind-the-scenes look at their mineral ...

I think about oxygen a lot more than I used to. This is because I am studying a chemical defense that turns ordinary oxygen, the same old stuff we obtain from breathing air – the same stuff that is ...

A new study suggests the world's oxygen-depleted seas may have a chance of returning to higher oxygen concentrations in the ...

The aim of the book “Oxygen atom transfer reactions” is to outline some recent developments in the studies of oxygen atom transfer mechanisms in catalytic oxidation reactions based on several ...
