Anomalous Magnetization Dynamics After Dual Optical Excitation

Advanced Physics Research, EarlyView.
We demonstrate that dual‐pump femtosecond excitation in copper leads to a pronounced, non‐additive change in spin and orbital relaxation dynamics compared to single‐pulse excitation. Time‐resolved magneto‐optical Kerr effect measurements reveal a 2.5× increase in angular momentum decay time, highlighting a new route to ultrafast control of electronic ...

Stabilization versus flexibility: Detergent‐dependent trade‐offs in neurotensin receptor 1 GPCR ensembles

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Detergents provide essential membrane‐mimetic environments for studying G protein‐coupled receptors (GPCRs), but their molecular impact on receptor energetics remains incompletely understood. We combined ligand binding, thermostability measurements, and atomistic molecular dynamics to dissect detergent‐ versus ligand‐driven stabilization in a ...
