Marine anoxia is characterized by the oceans being severely depleted in dissolved oxygen, making them toxic and thus having devastating impacts on the organisms inhabiting them. One such event, known as Oceanic Anoxic Event ...
For the first time, an entirely new class of super-reactive chemical compounds has been discovered under atmospheric conditions. Researchers from the University of Copenhagen, in close collaboration with international colleagues, ...
