Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key oxygen-processing enzyme back hundreds of millions of years before the Great ...

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 ...

Aerobic respiration began hundreds of millions of years earlier than previously thought, a new study suggests.

Scientists have discovered a surprising source of oxygen on the deep ocean floor, challenging the long-held belief that sunlight is essential for its production. Research in the Pacific's ...

Oxygen is everywhere on Earth today. But that hasn’t always been the case. Scientists think oxygen only became a lasting part ...

NASA's Carbothermal Reduction Demonstration (CaRD) project has completed an important step toward using local resources to support human exploration on the moon. The CaRD team performed integrated ...

Far below the reach of sunlight, in water cold enough to freeze most life in its tracks, scientists have found oxygen being ...

An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only ...

Mining activity could negatively affect the seafloor ecosystem, scientists warn. Rare metals on deep sea and ocean floors miles below the surface produce "dark oxygen," and mining these minerals could ...

"Dark oxygen" is being produced deep in the ocean, and scientists are baffled by the strange phenomenon, according to a new study. In science class, kids learn that plants need sunlight to do ...
