New research reveals a powerful yet overlooked driver of climate change: Intensifying ocean eddies. These swirling currents—that break off from major currents—are redistributing heat and nutrients in the ocean and amplifying climate extremes in key coastal ecosystems.

 

In a surprising new study, Australia’s most famous plant-eating dinosaur has been described as a “picky eater with a nose for good food” when it roamed across the continent around 96 million years ago.

After examining different parts of the skull from new bones of the large-bodied ornithopod Muttaburrasaurus langdoni, fossil experts from across Australia and the US have released several new insights in a journal article published in PeerJ.

A fossil skull provides new clues about how dinosaurs ascended to their full Jurassic power.

Seismicity decreases with depth, though it turns to increase in the mantle transition zone. It has been believed that pressure-induced phase transitions of olivine are the cause of high seismicity in the mantle transition zone. We experimentally showed that a diffusionless phase transition of olivine to poirierite triggers faulting. Our findings provide a natural explanation for the cause of high seismicity in the strongly deformed areas of ‘cold’ deep subducted slabs.
