Scientists have found a new way to detect subtle chemical signatures in seawater, revealing previously invisible details ...

A team led by the University of Miami Rosenstiel School has documented a measurable decline in nitrite levels inside one of ...

Research reveals ocean dead zones are dynamic systems, with shifting chemistry that affects nitrogen cycles, carbon storage, ...

In what's described as a key advancement for the development of systems to help propel humans into deep space, scientists have demonstrated a method of extracting oxygen from water in microgravity ...

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, ...

The Earth's deep interior may absorb more chemical oxygen than previously thought, revealing a new geological process ...

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 ...

Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason—we humans need molecular oxygen (O 2) to breathe, and space is essentially devoid of it.

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 ...
