Congrats! Looking forward to see it growing :)

Check this out! A napari plugin for AI-based analysis of microbial bioimages! 🔬🦠💻

And we are done --- #SMLMS2025 is over, and it was great. Thank you Uli & Ulrike & all the helpers 👍, and thanks to everyone joining this event 🙏 ... safe travels home & see you soon!

Next on stage is Jonas Ries @jonasries.bsky.social from Max Perutz Labs in Vienna sharing great work on a MINFLUX simulator that helps in designing experiments 👉🏻 SimuFLUX #SMLMS2025

Great presentation of @gomez-mariscal.bsky.social. Covering PhotoFiTT, DL4MicEverywhere, resolution-matching and many other aspects of the FAIRy universe 💻🔬🧚‍♂️ #DeepLearning #Microscopy

Estibaliz Gomez de Marisca @gomez-mariscal.bsky.social from Lisbon going live and sharing great work on AI-empowered microscopy #SMLMS2025 and accessible AI

Johannes Hohlbein @hohlbeinlab.bsky.social from Wageningen presenting his great work on the dynamics of the E. coli replication initiator DnaA #SMLMS2025

Jarno Mäkelä @jmakela.bsky.social from Aalto University shares his great work on single-molecule dynamics of heat shock proteins in E. coli #SMLMS2025 (unpublished work, so no images here)

First on stage is Maja Klevanski @majaklevanski.bsky.social from Heidelberg University presenting her great work on multiplexed super-resolution imaging of proteins and glycans in tissue #SMLMS2025

We are so happy to have Zaida Luthey-Schulten here at #SMLMS2025 as a keynote speaker. Zaida is the Director of the NSF Science & Technology Center of Quantitative Cell Biology and Endowed Professor at UIUC. She pioneered 4D modelling of an entire cell integrating experimental data. So inspiring!

Yersinia actively downregulates type III secretion and adhesion at higher cell densities Author summary Bacteria can use the type III secretion system (T3SS), a molecular syringe-like device, to manipulate host cells by injecting effector proteins. Yersinia enterocolitica, a pathogenic ba...

Yersinia enterocolitica cells downregulate the T3 secretion machinery at high cell densities, likely to promote dissemination and infection spread. Nice work by the Diepold lab @diepold-lab.bsky.social, happy that I could contribute a little bit to it. #bacteria #infection

New preprint from the Diepold lab describing major chromosome and plasmid rearrangements during secretion in Y. enterocolitica! 🦠🔬 Happy that I could contribute a bit 👇

Hi Henrik,
Thanks, this sounds to be exactly what we are looking for. Regarding periplasm, a colleague mentioned the pelB leader sequence to me. I can give you feedback once we tried it out!

Hey bacteriologists!
I want to test fluorescent proteins on different locations within E. coli cells and search for good membrane anchoring and periplasmic leading sequences. What are good candidates?
