Sanctions contre Israël, « non à la guerre » : l’Espagne cultive sa singularité en Europe Madrid a remis à l’agenda, sans succès, la rupture de l’accord d’association entre l’Union européenne et l’État hébreu. De manière générale, Pedro Sánchez se pose en champion d’une voie européenne indépendante, qui trouve cependant ses limites dans le rapprochement débuté avec la Chine.

Beyond the #science, every image is a thing of beauty.

I think a world-tour exhibition has to happen at one point.

A surface rendered view of an endosome. The endosome surface is rendered in blue with dimples on it. In specific regions of the endosomal surface, clusters of proteins are seen as aggregates of blobs, coloured in yellow and red.

🚨New paper out today in @acs.org ACS Nano, showing how expansion microscopy can visually quantify the cell surface receptor turnover mediated by signalling & receptor organising machineries on the surfaces of endosomes, some of the smallest organelles in cells. 🧪 🔬 1/ pubs.acs.org/doi/10.1021/...

Dear colleagues, With deep sadness I share the news that Andreas Engel passed away last Wednesday, at the age of 82, after a courageous fight against an aggressive caner. Only half a year ago, he was out hiking in the Italian mountains with his wife Barbara, walking 160 km in a single week. Andreas trained as a physicist in Bern, Switzerland, before heading to John Hopkins University in Baltimore for his postdoctoral work. He then led a research group at the Biozentrum in Basel, and in 1985 took on the role of a group leader in research and development at Ilford Ltd. in Fribourg, Switzerland. In 1987, he joined forces with his colleague Ueli Aebi to establish the Maurice E. Müller Institute at the Biozentrum of the University of Basel. Together, Ueli and Andreas served as professors for structural biology there for almost a quarter century, leaving a lasting mark on the field of structural biology as we know it today. Andreas Engel was a true pioneer. He was among the first to apply atomic force microscopy (AFM) with the tip operating under water, and one of the earliest researchers to perform 3D reconstructions using scanning transmission electron microscopy, achieving remarkable high-resolution maps of porin 2D crystals by STEM. He became a leading expert in membrane protein 2D crystallization, and his group played a key role in the determination of the first aquaporin structure, in collaboration with Peter Agre and Yoshinori Fujiyoshi. As he approached retirement from Basel, Andreas founded the Center for Cellular Imaging and NanoAnalytics (C-CINA) of the University of Basel, which in 2009 operated among others one of the very early Titan Krios instruments. From 2008 also held a professorship at Case Western Reserve University, Cleveland, followed by a position at TU Delft in the Netherlands in 2013. In 2020, he was among the founding members of CryoWrite, a company in Basel that he led as CEO until recently. His contributions to science, to the tools of str…

Sad news on the passing of Prof. Andreas Engel, a pioneer in the field of cryo-EM (shared with the 3DEM community by Henning Stahlberg).
Andreas' kindness, warmth, and enthusiasm for science and his colleagues will be missed.

After the poster, the presentation ! #FOM2026

It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density. Lipid-CLEM, now out in @natcellbio.nature.com brought to you by @mathilda95.bsky.social changes that:

I think this is the most useful tool for the democratization of scripts for biological research in a long time.

This week @jeremie-bic.bsky.social presented his work on sample clearing and light-sheet imaging during @france-bioimaging.bsky.social annual meeting. This is the pure définition of the "Whaou" effect! Congrats !!!
