Earth's mantle is far from a uniform reservoir; it is a complex archive of our planet's formation, differentiation, and long-term evolution. From the lithosphere down to the core-mantle boundary, mant...

Seismic waves tell us that something unusual is happening in the lowermost few hundred kilometers of Earth’s mantle. Beneath Africa and the Pacific lie two enormous thermochemical structures known as ...

Achal Agrawal is part of Nature’s 10, a list of people who shaped science in 2025.

Is the lower mantle boring? For a long time, the lower mantle was thought to be relatively featureless and uniform compared to the more dynamic upper mantle. But recent seismic observations are challe...
