Hidden store of manganese may have helped Earth get its oxygen
Deep below our feet, manganese may exist in a form we have never seen before, and this underground source of the metal could have played a role in the story of how Earth got its oxygen.

Ocean collapse triggered ancient wildfires, research suggests
Ocean collapse triggered ancient wildfires, research suggests Gaby Clark Scientific Editor Robert Egan Associate Editor Research led by the University of Alabama found that widespread wildfires during one of Earth's ancient environmental crises did not trigger an ocean collapse but were a consequence of it.
