Running Models, Chasing Bugs – from Crashes to Convection

Prachi Kar February 18, 2026

Mantle convection may unfold the hidden stories of planetary interiors over billions of years, but geodynamic models can crash in milliseconds. While figures in papers often show smooth convective flows with elegant plumes and slabs, the path to those results is not very easy. This week, Prachi Kar, a PhD candidate at Arizona State University, shares her honest thoughts on the part of geodynamics ...[Read More]

Journey Towards the Centre of the Earth: The Secret Behind the Long-Term Survival of Large Low-Velocity Provinces

Prachi Kar October 8, 2025

Geophysicists have long been intrigued by the enigmatic “blobs” residing deep within Earth’s lower mantle — the Large Low-Velocity Provinces (LLVPs). Ever wondered what keeps these gigantic thermochemical structures surviving for billions of years despite the mantle’s vigorous convection? In this week’s News & Views, Prachi Kar, a PhD candidate from Arizona State University, delves into Earth’ ...[Read More]
