i had long idly wondered about the origin of the name “Escherichia"
c0nc0rdanceThe headlines are still covering the cyclosporiasis outbreak from lettuce, but let's talk about a different summer, long ago. The headlines in Bavaria would have called it "summer diarrhea" & it was killing babies. Enter our hero, Professor Theodor Escherich of the Julius Hospital, Würzburg.

Reconstitution of actomyosin networks in cell-sized liposomes dissects distinct mechanisms of membrane blebbing and symmetry breakingActin network organization dictates how and where membrane blebs form, revealed through reconstitution and simulations.www.science.org
Thrilled to share our latest work, led by @aryantaheri.bsky.social and Julia Peukes! Using cryo-EM and cryo-ET, we reveal how KIF21B’s distal tail engages multiple tubulin dimers along a protofilament, enabling persistent microtubule attachment and crosslinking. www.biorxiv.org/content/10.6...
This epic paper, which has been a heroic 10 year journey for the lead author, Ricardo Barrientos, is finally out in Cell today! Many thanks to all co-authors, especially Billie Meadowcroft and Andela Saric for their beautiful MD simulations www.cell.com/cell/fulltex...
Basement membrane turnover controls cell shapeBasement membranes are scaffolds of proteins, like collagen, that give organs shape.
During development, basement membranes must adapt to the growing organ. We infer how

Always one of the nicest cell biology conferences!
SBCF🔬 Cell la Vie 2026 📅 October 21–23 | Paris Three days of cell biology, scientific exchange, and networking across all career stages. 🎟️ Registration and poster submissions are open - but places are limited!
✍️ The @romet-jegou-lab.bsky.social published a new article 📖 @pnas.org 📃 Vimentin promotes actin assembly by stabilizing ATP-actin subunits at the barbed end 🔗 www.pnas.org/doi/10.1073/...
New preprint! How does a cell "know" how big to make its nucleus? This has puzzled biologists since the 1800’s. We show the answer is physics: colloid osmotic pressure. 🧵1/5
bioRxiv BiophysicsNuclear size and physical properties of the nucleoplasm are determined by colloid osmotic pressure at the nuclear envelope https://www.biorxiv.org/content/10.64898/2026.07.21.739918v1
Take-home message: even when trying to be thorough and open, making complex analysis that require expert annotations reproducible is *hard*. There a crucial need to develop automated, unbiased procedures that work on really challenging data ( 👀 @flevet.bsky.social)!

What determines how epithelial cells divide when shape cues disappear? Our new work shows that division follows the axis of maximal stress anisotropy. This “principal-stress rule” links mechanics, proliferation, and homeostasis. Amazing work from @luanger.bsky.social. www.biorxiv.org/content/10.6...
