The University of Reading led the most detailed ever study forecasting how vulnerable the vast […]

The permanent rise of oxygen in the Earth’s atmosphere, which fundamentally changed the subsequent nature of Earth’s habitability, occurred much later than thought, according to new research. And the study, from an international team led by the University of Leeds and including researchers from the University of California-Riverside, Harvard University, […]
