Far below the oceans and continents we know, Earth’s deep mantle appears to have stored far more water in its early history than scientists once imagined. New experimental work on high‑pressure ...

When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers discovered that bridgmanite deep in the mantle can store far more water at high ...
