A prehistoric Equisetum horsetail plant that survived 400 million years produces oxygen isotopes and water with an extreme chemical signature ...

Chemical reactions that produce pollutants in the atmosphere, and the chemistry of fuel combustion inside a vehicle engine, have some striking similarities. For each set of reactions, oxygen's role is ...

Scientists have long sought to explain a key mismatch in Earth's early history: oxygen-producing photosynthesis evolved hundreds of millions of years before atmospheric oxygen began to rise during the ...

Low oxygen and rising carbon dioxide in mangrove waters may shrink critical nursery habitat for young fish and threaten ...

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 ...

For the first time, researchers have managed to isolate and directly observe individual oxygen atoms inside liquid water, catching a substance that usually hides behind the familiar H 2 O formula in ...

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 ...

Chemists, when they are designing or building new molecules, can be thought of as architects and builders. An organic chemist can plan a blueprint for a new molecule, and synthesize it with precision ...

About once every decade, the Oxygen Healing myth bubbles to the surface again. Loosely speaking, it claims that all diseases are caused by low levels of oxygen in the body. If you buy brand X or Y or ...
