Etats-Unis : un chercheur français refoulé pour avoir exprimé « une opinion personnelle sur la politique menée par l’administration Trump » Le ministre de la recherche français a dit sa « préoccupation », mercredi, après cette décision des autorités américaines. Le chercheur du CNRS aurait subi un contrôle aléatoire à son arrivée, avant q...

A French researcher going to a conference in the US had his phone and computer searched (and then confiscated) and was refused entry and expelled because they found stuff critical of Trump.
I guess lucky that he wasn't detained for weeks?
Don't travel to the US. No conference is worth the risk

I lost my job at the National Science Foundation yesterday, along with 167 of my colleagues, including some dear friends. This was the best job I've ever had, and I thought it would be my last. The PI community has been sympathetic and supportive, without exception. I will miss working for you.

Linear-viscous flow of temperate ice Accurately modeling the deformation of temperate glacier ice, which is at its pressure-melting temperature and contains liquid water at grain boundaries, is essential for predicting ice sheet discharg...

Not seeing a lot of discussion about this. Some researchers have estimated the Glen's flow law exponent n as ~ 1 rather than 3-4 for temperate ice. This could mean that the world's most critical glaciers are linear-viscous are their base.

Top: It's a sunny day and a lady in a wide brimmed hat, long sleeved shirt and bike shorts stands on a grassy hill in front of a large braided river occupying a mountain valley. Bottom: three block diagrams illustrating how faults can interact with river channels by creating a dam, shifting them laterally, or tilting the channel in retrograde.

10 years ago I thought I wasn't smart enough to study #geology, but some colleagues convinced me to try anyway. Today I just published my 2nd paper, which explores how fault ruptures can alter river behaviour and flood hazard. Check it out here! www.sciencedirect.com/science/arti...

Time for some nice #landslide simulation using Hergarten's minvoellmy implementation in #TopoToolbox. The DEM shows the Eiger Northface and the detached volume is 5 Mio m^2.

Landscape changes caused by the 2024 Noto Peninsula earthquake in Japan Deformation due to the Noto Peninsula earthquake showed that its repetition shaped the Peninsula’s modern landscapes.

Our work on surface deformation by the Noto Earthquake is finally out! Fukushima Yo led a team to create and ground-truth a full 3D deformation field from InSAR on the entire Peninsula. We show that repetition of similar quakes explains the 1st-order landscape features. 1/5
