There was so much to unpack with this data, we teamed up with the marvellous @margotriggi.bsky.social to help explain what we think is going on. (Please also check out our model of central apparatus assembly here: www.biorxiv.org/content/10.6...)

Are you a cell biologist who secretly thinks cellular cryo-electron tomography is just George Palade-era EM, but fancier? Join this webinar to see how modern #teamtomo has shifted from pretty pictures to quantitative, local membrane biology, and how that changes the questions we can ask.

We are pleased to announce that the 4th Sino-French BioImaging Symposium (SFBS 2026) will be held in Bordeaux from 14 to 21 October 2026! 🔹An advanced thematic school (14-16 October 2026) 🔹A three-day international symposium (19-21 October 2026)

We have been thinking a lot recently on how to share and interact with code when doing image analysis. This is one piece of the puzzle. Awesome work driven by Bruno S. Always a delight to work with @henriqueslab.bsky.social 🫶 More to come soon 😄.

Thank you @ucdlibrary.bsky.social for sourcing this fantastice read by @steveroyle.bsky.social for me. Highly recommended for anyone interested in learning more about #cellbiology #biologicalimaging #imageanalysis #datavis also more people should read the #quantixed blog.

🚨 Job Alert! 🚨 We have an opening at our Microscopy Core Facility in Turku 🇫🇮. If you love imaging 🔬 and helping scientists succeed, we want you! 👇 abo.rekrytointi.com/paikat/index... #Microscopy #ScienceJobs #CoreFacility #Imaging @turkubioscience.bsky.social

We’re hiring! @jcellsci.bsky.social is looking for a Reviews Editor to join the team. This is a fantastic opportunity for someone who loves #cellbiology and wants to stay connected with the field. A great chance to work for an organisation that believes in helping the community! Details below👇

🎉 Congrats to Louise Fougère, winner of the #SBCF PhD Award 2025! Her work using Arabidopsis, in Yohann Boutté’s lab (Univ. Bordeaux / CNRS) identified a novel ER–Golgi intermediate network, advancing our understanding of Golgi maturation, with key results published in Nature Cell Biology.

If you're wondering if your manuscript could be suitable for our special issue but are unsure, don't hesitate to reach out 👍

Sample prep with @jeremie-bic.bsky.social for Lemolish observation with Mathieu Ducros... stay tuned for some great images @bic-bordeaux.bsky.social !!! #flurescentfriday #clearing #lightsheet
