The rise and fall of massive ice sheets have shaped Earth’s surface for millions of years, but their influence may extend far deeper than previously recognized. This week in News & Views, Tao Yuan, a PhD student at the University of Colorado Boulder, explores how glacial cycles can alter lithospheric plate motions and even modulate the spreading of mid-ocean ridges. The ongoing melting of glac ...[Read More]

Reflecting on the 2025 Gordon Research Seminar (GRS) – Interior of the Earth

This week in News & Views, Heidi Krauss, a PhD student at Michigan State University, shares her experience co-chairing the 2025 Interior of the Earth Gordon Research Seminar, held at Mount Holyoke College in South Hadley, Massachusetts. Earlier this year, I had the opportunity to help co-chair the Gordon Research Seminar (GRS) on the Interior of the Earth, held just before the main Gordon Rese ...[Read More]

A whole mantle dynamical framework for Venus

Geodynamicists have long grappled with the complexities of Earth’s mantle dynamics—modeling Venus’ interior adds an extra layer of challenge without the benefit of plate tectonics! This week in News & Views, Madeleine Kerr, a PhD candidate from the University of California, San Diego, explores how numerical modeling can shed light on mantle dynamics and the evolution of Earth’s eni ...[Read More]

How Hot our Moon Can Get: Mapping Radioactive Elements and Thermal State of the Lunar Interior

Geochemists and geophysicists, even with their favorite tools, have often scratched their heads while probing Earth’s deep interior—one  can only imagine the challenges while applying those techniques to the Moon! This week in News & Views, Arkadeep Roy, a PhD candidate from the University of Arizona demonstrates how the intersection of experimental petrology, geochemistry, and geophysic ...[Read More]
