Scientists have discovered that two intense spells of volcanic activity triggered a period of global cooling and falling oxygen levels in the oceans, which caused one of the most severe mass extinctions in Earth history - the 'Late Ordovician Mass Extinction', 450 million years ago.

Scientists have now used climate modeling, rather than storm records, to reconstruct the history of hurricanes and tropical cyclones around the world. The study finds that North Atlantic hurricanes have indeed increased in frequency over the last 150 years, similar to what historical records have shown.

Scientists have published an analysis laying out how the tiny beads of glass inside many meteorites came to be -- and what they can tell us about what happened in the early solar system.
