Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that ...

A new study published in the journal Nature Geoscience found evidence of oxygen production near polymetallic nodules located deep in the ocean. Called dark oxygen, this oxygen is being produced ...

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 H2O formula in the ...

Recent studies and warnings from NASA have sparked global concern about the long-term sustainability of Earth’s oxygen supply. The implications of a diminishing oxygen reserve are profound, ...
