Adaptive Twisting Metamaterials

Advanced Materials, Volume 38, Issue 21, 13 April 2026.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Joule Heating in the Northern Hemisphere During Geomagnetic Storms Driven by High‐Speed Streams and Coronal Mass Ejections

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a robust method for estimating the auroral Joule heating in the northern hemisphere by combining SuperMAG, SuperDARN and AMPERE data products. This method is applied to 292 storms during 2010–2023. Temporal evolution and spatial distributions of the storm‐time Joule heating are studied using a superposed epoch analysis, with the ...
