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.

Core Movements Could Be Causing Tiny Shifts in Earth’s Spin Speed
Researchers use ancient eclipse data and new machine learning techniques to understand what processes changed the length of Earth’s days over the past 3,000 years.
Crustal Melts at the Core-Mantle Boundary
Seismic waves get sent in all directions for deep mantle anomalies, and a new analysis shows where those scatters lie and what properties they have.
Seismology Helps Us Understand How Material Flows in Earth’s Deepest Mantle
Recent progress in the analysis of seismic waves enables us to determine where, and sometimes how, the base of the mantle deforms.
Tales and Textiles Can Communicate the Science of Planets
Artists are working with a scientist and a writer to boost public understanding of the science of planetary interiors.
Digging Deep into Interactions Between the Core and Mantle
A new book presents major advances in our understanding of core-mantle interaction and co-evolution, and showcases technological developments improving our insights into deep Earth processes.
El hierro está en el centro de este debate de las ciencias de la Tierra
Un nuevo estudio investiga el estado del hierro en el interior del planeta. Los hallazgos tienen repercusiones para comprender la estructura del núcleo interno.
Iron Is at the Core of This Earth Science Debate
A new study investigates iron’s form at the planet’s interior. The findings have repercussions for understanding the inner core’s structure.
The Seven-Ages of Earth as Seen Through the Continental Lens
The 4.5-billion-year record contained in Earth’s continental crust reveals a seven-phase evolution, from an initial magma ocean to the present-day environment in which we live.
Swinging Strength of Earth’s Magnetic Field Could Signal Inner Core Formation
The magnetic record stored in rocks documents the liquid core’s behavior and possibly when the inner core formed. Whether it formed half a billion or more than a billion years ago, however, is up for debate.
