How cells decide where to go? #CellMigration

Last year we published our 1st paper @cellcommlab.bsky.social, showing how actin-based membrane oscillations define a new direction ( #cancer & non-cancer #cells )

#CellMigration happens all the time in our bodies. This may (or not) rely on adhesion molecules

#Cancer cells switch strategies during metastasis to invade other tissues

Naomi Wee (naomiwee.com) did this neat movie to explain it:

#SciSky 🧪🔬 @cellcommlab.bsky.social

New preprint! When and how do active flows become turbulent? We found that, in unconfined active nematics, the transition to turbulence is discontinuous! With @the-chaotician.bsky.social @mpipks.bsky.social

Light reflecting off a sculpture of different structural domains found in proteins. Made from steel.

I mostly see the protein sculptures I build in the lighting of my workshop. It’s fairly static and dull lighting. When they are close to being finished, I bring them into the house and enjoy watching how they change under different natural lighting throughout the day. They are so much more dynamic!

Would you prefer to lead a lab alone or together with a science buddy? How interesting would be a research institute where joint labs are the standard?!

Group leader positions at the IMP | Research Institute of Molecular Pathology

i might be biased, but this place is amazing: great colleagues, vibrant campus, brilliant students/postdocs - and Vienna! perfect for starting an ambitious project. apply now for a GL position at the IMP …

Ok, trying to bring my community back together... I created a starter pack for lipids and membrane protein aficionados!

Feel free to share, add and distribute, so we can come together again! 😍

I started a list of people working broadly on cell adhesion and cell migration. I likely missed many, please drop me a message if you want to be added

Hey super cool
Followed them all
Please add me too !

Scientists in Switzerland starter pack, with our avatars

I have created a starter pack of scientists in der Schweiz so we can all hopefully find each other 🇨🇭🧪

Add me please :D

Sunday #NewPI thoughts

This is a movie of actin filaments in a cultured cell. I like watching it and I hope you do to.

“I’ve noticed I’m not in your starter pack. Any particular reason for that?”

So cool! I was just looking for this since I joined a few days back :D add me please

Ever wondered how eukaryotic cells got their nucleus? If so, check out Anja and my new hypothesis article - which builds on the ‘inside-out model of eukaryogenesis’: journals.asm.org/doi/10.1128/...

Now out in NSMB for those who missed our biorxiv back in 2023.. bacterial ESCRT-III-like #Vipp1 forms dynamic spiral filaments on membrane! Spirals are springs that drive 3D ring formation in the spiral centre! 😵‍💫 wonderful collaboration with Adai Colom’s lab and @rouxlab.bsky.social

Hello BlueSky! Just arrived 😁

The best reason for quitting X came after announcing it.
