Very excited to share the latest work from our lab in @insight.jci.org, highlighting a role for the #septin #cytoskeleton in protecting against "leaky gut", by recruiting non-muscle myosin II and stabilizing the tight junction.

New septin paper by our next door lab neighbors @ebrahim-lab.bsky.social, and on the cover of JCI Insight no less.
Septin 9 reinforces intestinal epithelial junctions, preventing leaky gut and inflammation.
Check it out!

Happy to share our new paper, just published in @cellpress.bsky.social. We show that our zap&freeze approach can be used in human brain tissues to study synaptic membrane dynamics! Our brain is ultrafast after all! nam02.safelinks.protection.outlook.com?url=https%3A...

That’s a good deal! Do you also offer similar services for boring, incremental scientific publications?
For a small fee, I will unfairly attack your PhD online, increasing your readership in the resulting backlash

Two more pre-prints from the group 🎉 Riccardo explored how cells could control surface condensates by regulating bulk exchange (arxiv.org/abs/2511.03619). Filipe studied the impact of non-local interactions onto phase separation (arxiv.org/abs/2511.05214). Some more details in the thread:

My team and I have been able to discern that sperm whales have their own alphabet and that this alphabet seems to be pillared by their own version of vowels. I’ve learned that humans are far from the only species intelligent and complex enough to develop a form of language and culture.

Scientific journals: we don’t want you using generative AI because it makes shit up.
Same journal: here is an AI summary or evaluation of this paper. This might be more useful than the actual abstract or paper that the authors freaking wrote

Still posting cytoskeleton videos, it seems. Actin this time.
Sample: Lifeact-eGFP in HeLa cells.
Modality: Airyscan confocal
Timestamp is mm:ss and the scale bar is 5 µm.

Interactions of cells in a collective lead to global rotation.
In 80% of the case HUVEC cells turn clockwise.

Heat pumps are the most efficiency heating technology ever invented.
That's because they harvest, compress and transport pre-existing heat from the air, the ground or the water.
Compared to a gas boiler heat pumps deliver ~4x more heat for each unit of energy inout.

This is a very good analogy.
Discourse surrounding “AI” these days often feels like a guy showing you his shovel and you say, “that’s a nice shovel” and he says “I am going to perform surgery on my mother with this shovel” and you say “Oh God please don’t that is not what a shovel is for.”
