Missing nitrogen traced to deep Earth core in planetary formation simulations
Tokyo, Japan (SPX) Apr 14, 2025 A longstanding mystery in Earth science may finally have an answer: why Earth's rocky mantle contains so little nitrogen compared to other volatile elements. According to a new study from Ehime University, most of Earth's nitrogen may have sunk into the core during its formation, effectively hiding it from view for billions of years. During Earth's infancy, the planet was covered by a deep magma ocean. As the planet differentiated, heavy metals descended into the core, while lighter elements forme ... read more |

Massive eruptions did not trigger dinosaur extinction
Berlin, Germany (SPX) Dec 20, 2024 Massive volcanic eruptions in India, once theorized as a potential cause of dinosaur extinction, likely played a minimal role in their demise, according to new research by climate scientists at Utrecht University and the University of Manchester. Their findings suggest that while these eruptions caused a temporary cooling period, their climatic effects had dissipated thousands of years before the Chicxulub meteorite struck Earth 66 million years ago, marking the end of the dinosaur era. For decade ... read more
