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

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...

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.

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.

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...

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.

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
