A newly discovered mechanism could explain the shock finding last year that oxygen is produced by metallic nodules on the ...

Scientists predict that in a billion years, the oxygen level on Earth will drastically decrease, according to "Nature ...

To this end, we assessed the effect of oxygen fugacity on the melting temperatures of deep mantle materials to constrain the ...

The seals’ ability to detect the amount of oxygen in their blood may help them make diving decisions and avoid drowning.

Could lumpy metallic rocks in the deepest, darkest reaches of the ocean be making oxygen in the absence of sunlight?

This event, which was likely caused by the evolution of photosynthesis, is a major milestone in Earth's history, and saw the first rise of oxygen concentration ... a great ocean that covered ...

Deep beneath the ocean's surface, in the pitch-black abyss, scientists have uncovered a fascinating phenomenon: "dark oxygen." Unlike the oxygen produced by plants through photosynthesis ...

lowering productivity and therefore ocean-wide oxygen demand, the team suggested. This would have set up a positive feedback loop further oxygenating the deep ocean. Well-oxygenated depths provided ...

A new study published on Saturday finds that oxygen levels have dropped in lakes worldwide due to lasting climate warming and ...

A study of ancient stromatolites reveals that ammonium reservoirs in early Earth's oceans, likely influenced by volcanic activity, may have supported microbial life before the Great Oxidation Event.
