Water Stored in the Mantle for Millions of Years May Be Linked to Continental Volcanism
New research shows that intraplate volcanism is more likely to occur over areas of the mantle that are more hydrated—particularly those that have been hydrated for a long, long time.

Modeling Mantle Dynamics as the Earth Slowly Cools
An update of the convection code ASPECT enables full coupling of plume dynamics with buoyancy effects of transition zone phase relations, showing how early layering gave way to whole-mantle plumes.
