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.

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

Zebrafish use spectral information to suppress the visual background
Vertebrate eyes first evolved in water, where spectral content rapidly fades with distance. Zebrafish exploit this loss by antagonizing cone signals to suppress the background, pointing to distance estimation—rather than color—as an ancestral cone function.

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

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

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.

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.🤔

Whole-body coarticulation reflects expertise in sport climbing
Taking sport climbing as a testbed, we explored coarticulation in naturalistic motor-behavior at the level of whole-body kinematics. Participants were instructed to execute a series of climbing routes...

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!
