The appearance of oxygen in Earth's atmosphere was a turning point in the history of our planet, forever transforming the ...

A new study has revealed how phosphorus, a nutrient essential for photosynthesis, surged into ancient oceans and started ...

Oxygen-producing cyanobacteria triggered ... Thus it's possible that the microbes carry out a "cryptic" sulfur cycle that we do not yet understand. These findings offer a new window into how life ...

When did the Earth reach oxygen levels sufficient to support animal life? Researchers have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, ...

For now, life is flourishing on our oxygen-rich planet, but Earth wasn't always that way – and scientists have predicted that, in the future, the atmosphere will revert back to one that's rich in ...

The global ocean on Jupiter’s moon Europa contains about twice the liquid water of all the Earth’s oceans combined. New research suggests that there may be plenty of oxygen available in that ocean to ...

This ultimately cuts off the possibility for photosynthesis to occur. Due to this sudden cutoff of oxygen production, levels rapidly plummet, and life as we know it comes to a dramatic end. According ...

New research reveals when oxygen flips from stable to reactive, "singlet" form connecting the chemistry of life with ...

We think of oxygen as life, sustenance, a literal breath of fresh air. But it's actually a very reactive element. Anyone who's burned a log has witnessed this firsthand. So why do so many life-forms ...

An international team analyzed 656 lakes across five continents to provide empirical evidence supporting a long-held theory regarding low deep-water oxygen concentrations, or anoxia. Abigail Lewis ...

ANN ARBOR, Mich.—Data from the Cassini-Huygens satellite showing oxygen ions in the atmosphere around Saturn’s rings suggests once again that molecular oxygen alone isn’t a reliable indicator of ...
