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 ...

At TU Wien (Vienna), it has become possible to control one of the most important chemical processes: switching oxygen molecules between a reactive and unreactive state. Oxygen atoms are highly ...

Using computer simulations, researchers have shown that the oxygen molecule (O₂) is stable up to pressures of 1.9 terapascal, which is about nineteen million times higher than atmosphere ...

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 ...

The European Space Agency's Rosetta mission observed molecular oxygen (O2) emanating from Comet 67P/Churyumov-Gerasimenko. New Caltech research reveals that comets can naturally produce molecular ...

For the first time, astronomers have found molecular oxygen — the same gas humans need to breathe — in a galaxy outside the Milky Way. Oxygen is the third most common element in the cosmos, after ...
