Researchers at the University of Portsmouth examined ancient minerals to trace how oxygen levels changed between 3.4 billion ...

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

A new molecular classification framework reveals that oxidized organic compounds, rather than particle mass, govern the ...

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 ...

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 ...
