A breakthrough discovery of oxygen production in darkness could redefine life's origins on Earth and open new frontiers in ...

A project is underway to investigate the production of “dark” oxygen further. Understanding the phenomenon better could help ...

Gas from the seafloor has scientists wondering if oxygen could be found in the oceans of other planets.

The discovery is attracting attention worldwide as it challenges the conventional scientific consensus that oxygen is ...

Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the ...

Until this discovery, it was believed that oxygen could not be produced without sunlight Scientists have discovered “dark oxygen” being produced in the deep ocean, apparently by lumps of metal ...

Dark oxygen was discovered in oxygen-depleted zones, defying scientific predictions. It behaves chemically in areas with no sunlight, suggesting unknown interactions with deep-sea minerals.

For over a decade, researchers led by Andrew Sweetman of the Scottish Association for Marine Science (SAMS) encountered perplexing data indicating the presence of oxygen in this lightless environment.

Foraminifera, though eukaryotic, have adapted to use chemoautotrophy to enable them to survive where oxygen and sunlight are ...

But many studies have revealed that pulse oximeters can measure blood oxygen levels as higher than they actually are for people with dark skin. The FDA announced Monday that it has published draft ...
