Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

The strongest force in the Universe is the one that holds together the protons and neutrons in an atom’s nucleus. To unlock how elements are forged, the physics of neutron stars and more, scientists ...

For roughly 2 billion years of Earth's early history, the atmosphere contained no oxygen, the essential ingredient required ...

The oxygen isotope composition of phosphate (δ 18 O p) offers a powerful tracer for elucidating the complex pathways of phosphorus cycling in both terrestrial and aquatic ecosystems. By analysing the ...

Slow orbital changes caused pulses in Earth's oxygen cycle 500 million years ago, which spurred explosions of animal life.

Scientists at The University of New Mexico have found that the Earth and Moon have distinct oxygen compositions and are not identical in oxygen as previously thought according to a new study released ...

Positron Emission Tomography (PET) plays a major role in the early detection of various types of cancer. A research group led by Specially Appointed Professor Katsumi Kaneko of the Research Initiative ...

The article details the surprising prevalence of oxygen's green glow in celestial observations, particularly in nebulae and auroras, which is caused by "forbidden radiation" emitted by oxygen atoms in ...
