1 day ago · Oxygen is continuously replenished in Earth's atmosphere by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms.
4 days ago · Scientists find evidence of additional source of oxygen, raising questions about the origins of life on Earth.
6 days ago · A chemical reaction could be producing oxygen by splitting water molecules, but its source of energy remains unknown.
4 days ago · Scientists have made a stunning discovery on the ocean floor, 4000 metres below the surface, that could upend our understanding of the origin of life.
4 days ago · Researchers believe they have discovered oxygen being produced 4,000 meters below the sea surface, and think polymetallic nodules—the sought-after bounty of deep-sea miners—could be the source.
5 days ago · New research challenges a long-held assumption about oxygen in the deep sea, with scientists finding oxygen produced without photosynthesis in the Clarion-Clipperton Zone.
6 days ago · Baffling new results show that rocklike mineral deposits in the deep sea can produce oxygen
5 days ago · The existence and possible source of this dark oxygen may eventually rewrite the narrative of how life originated on Earth. As Sweetman explains, experts have long theorized that the planet’s ...
4 days ago · Scientists may have discovered 'dark oxygen' being created without photosynthesis. A deep sea shark and several eels are attracted to bait placed at the summit of the Cook seamount, as seen from ...
6 days ago · Scientists have discovered 'dark oxygen' being produced in the deep ocean, apparently by lumps of metal on the seafloor. About half the oxygen we breathe comes from the ocean. But, before this ...
