Two geoscientists, one with Princeton University, the other with Guangzhou Institute of Geochemistry, have developed a theory to explain how helium-3 leaks from the Earth's core into the mantle. In their study, reported in ...
It has long been known that humanity is exceeding planetary boundaries for nitrogen use. Scientists have now mapped those exceedances regionally for the first time. Whereas countries in north-western Europe and parts of India ...
