Oxygen-rich laboratory melts retained extra oxygen under pressure, revealing a possible transport mechanism within Earth.

Great Oxidation Event oxygen delay is explained by a 3.4-billion-year feedback loop: a new Nature Geoscience study shows early photosynthetic life's oxygen was routed underground via sulfur recycling ...

Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly ...

Oxygen provides the driving force for many vital chemical reactions. Two well-known examples include respiration, the process that allows living things to break down food to release its energy, and ...

A rat model study shows that hypoxia modulates IL-12 and IFN-γ cytokine dynamics during mycobacterial infection, with early ...

Researchers have quantified a pathway for the formation of molecular oxygen from the interaction of carbon dioxide with electrons, key information for searches of life on other worlds. Molecular ...
