And here we go: there is the 50 mm HeLa cell:

Excited to share my first PhD project: LabConstrictor 📒🐍 Have you ever created a Jupyter notebook with all your love 🫶, only for others to be unable to install it 🥲? LabConstrictor, comes to solve this! Check out how it works in the preprint 🔗 arxiv.org/abs/2603.107... or follow this thread ⬇️

If the whole paper (doi.org/10.1016/j.ce...) is a bit much to digest, check out this post! I also share a bit about what made me fall in love with🐟 and move into studying microglia👾

A final milestone of my Lisbon-era☀️ Such an interesting type of migration and I just love all those dynamic protrusions❤️. Compared to my bioRxiv thread bsky.app/profile/jale..., we have here more data especially on the attractive neurturin-Gfrα axis.

🚨 We are hiring TWO postdocs to join the Cell Migration Lab (cellmig.org) 🇫🇮 as part of the new Centre of Excellence in Immune–Endothelial Interfaces (IMMENs). Join us to decode immune regulation & develop next-gen imaging tools! 🧪🔬 Details in thread 🧵👇 #ScienceSky #Postdoc #AcademicJobs Please RT🫶

🚨 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

Interested in Zebrafish brain imaging? We released a 3D printed mold that's is super helpful for us. Check it out Customizable FDM-based zebrafish embryo mold for live imaging www.biorxiv.org/content/10.1... Work by Marcela and Jaakko in the lab

Now online! Zebrafish use spectral information to suppress the visual background

Mind-boggling. Remember seeing older papers on playing music to cultured cell lines. Would love to see the reviewer responses on this one.

Eric Peterman @errricpeterman.bsky.social, Jeffrey Rasmussen @jraslab.bsky.social @uwbiology.bsky.social & colleagues discover that microtubules regulate tissue-level navigation in skin-resident macrophages. journals.biologists.com/jcs/article/... Article: journals.biologists.com/jcs/article/...

Academic authors, here's a peek into the black box of journal publishing from an journal editor if you can bear it:

Cancer cells are notoriously plastic, but what triggers the changes in cell state? In our new Nature (@nature.com)‬ paper, Miranda Hunter (@mrndhntr.bsky.social‬) found that mechanical pressure is a key to this switch. Check it out here: go.nature.com/47iwDm2

Had thought to test this wild idea in the future but so cool to see Francesca Peri lab making it real: Xenografted human microglia in zebrafish, doing their job 😍https://www.biorxiv.org/content/10.1101/2025.08.27.672578v1.full.pdf

🐟 Zebrafish (Danio rerio): Clear as glass, zebrafish embryos let you watch organs form in real time. A powerhouse for studying organogenesis and regeneration, they’re also champions of transgenic expression of fluorescent proteins 🌈 image from Gopi Shah 🧪 #ModelMonday #DevBio

Interested in cell migration yet bored of the canonical translocation modes? 😴 Don’t worry — we @nordenlab.bsky.social with @aiopticalbiolab.bsky.social have multipolar migration back in stock! No need to follow the other cells: extend long protrusions and roam more freely🪼 in the crowded brain.

Are you looking for a postdoc? I will be looking for 2-4 people after the summer to join the lab !! Do not hesitate to reach out and disseminate !!

Skimming through biorxiv might improve your climbing? As a non-expert (climber and in this field), I was taught to climb the route mentally before physically. Movement coordination comes through repetitions as in any sport.🤔

Ever wondered how to manipulate mechanical forces in the developing zebrafish heart?🤓 Check out our new protocol by @cvagenapantoula.bsky.social and Hajime, where we describe magnetic bead grafting as an effective approach to study #mechanotransduction!🐟🔬 app.jove.com/t/67604/mani...

After ~3.5 inspiring years @nordenlab.bsky.social, I’ve migrated back to 'apical' Finland. The last months, I appeared a lot like these multipolar retinal cells. Excited to share more soon about their fascinating in vivo navigation!
