International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi says agency staff stationed at the Zaporizhzhia nuclear power plant "were again forced to shelter after missile attack ...
Scientists last autumn revealed that the gas phosphine was found in trace amounts in Venus’ upper atmosphere. That discovery promised the slim possibility that phosphine serves as a biological signatu...
Volcanic activity and changes in Earth's mantle were key to rise of atmospheric oxygen（图）
Volcanic activity changes Earth mantle were key rise atmospheric oxygen
2020/6/19
Oxygen first accumulated in the Earth's atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photos...
