“Our discovery of dark oxygen was a paradigm shift in our understanding of the deep sea and potentially life on Earth, but it threw up more questions than answers,” Sweetman, the leader of his ...

Dark oxygen produced on the floor of the ocean is challenging our understanding of how life may have started and where it may be possible elsewhere... Bubbles of oxygen are seen against a dark ...

MSU scientists studied microbes in Yellowstone hot springs to understand how life adapted to increasing oxygen levels.

Using this knowledge, the scientists built a unique sophisticated computer model to more accurately chart key changes in the carbon, nutrient and oxygen cycles deep into Earth's history ...

However, photosynthesis doesn't just drive the carbon cycle — it also creates the oxygen necessary for respiring organisms. Interestingly, although green plants contribute much of the oxygen in ...

And like plants, they also release oxygen, contributing at ... seagrasses and other forms of sea life interact sheds light on Earth’s carbon cycle. Carbon, a chemical element, is found in ...

In a groundbreaking study, scientists have discovered that deep-sea metal nodules are capable of producing oxygen, a revelation that could reshape our understa ...
