To this end, we assessed the effect of oxygen fugacity on the melting temperatures of deep mantle materials to constrain the ...

A research team led by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) was able to revive dormant stages of ...

A newly discovered mechanism could explain the shock finding last year that oxygen is produced by metallic nodules on the ...

Scientists have discovered evidence that Earth's oceans were once green, hinting that this could be a marker of early life, ...

In the vibrant yet fragile waters of the Gulf of Oman, spectacular phytoplankton blooms – visible even from space – unfold in ...

The seals’ ability to detect the amount of oxygen in their blood may help them make diving decisions and avoid drowning.

lowering productivity and therefore ocean-wide oxygen demand, the team suggested. This would have set up a positive feedback loop further oxygenating the deep ocean. Well-oxygenated depths provided ...

Imagine the world’s oceans with their beautiful blue color. Now, imagine that the same oceans were green. This is the intriguing possibility suggested by new research from Nagoya University in Japan.

This event, which was likely caused by the evolution of photosynthesis, is a major milestone in Earth's history, and saw the first rise of oxygen concentration ... a great ocean that covered ...

"Activity of microorganisms in the ocean played a central role in the evolution of atmospheric oxygen. However, we think this would not have immediately led to atmospheric oxygenation because the ...
