Geochemistry

A new study suggests Earth formed primarily from material in the inner Solar System, challenging theories about the origin of its water and other volatile substances.

A compact X-ray telescope developed by Tokyo Metropolitan University could create the first complete chemical map of the Moon, revealing its formation and evolution.

Scientists developed a new laser-based method combining geochemistry and marine ecology to accurately determine shark age, aiding conservation efforts for vulnerable species like the Speartooth Shark.
