Do #lipids carry the signatures of #evolution?🤔 In #Biochemistry Perspective, We 'provocatively' (as my former PhD guide & scientific guru Sankar put it ) propose an expanded view of the classic “lipid divide” idea feedback/critiques all welcome 🙌 #lipidtime pubs.acs.org/doi/10.1021/...

Oh to be a little Tardigrade walking across a microscopic slide. 🫧🐻🧪

Ups we did it again! Please mark your calender. EMBO Workshop “Lipid Code to Life”, taking place September 7–11, 2026, in Dresden, organized by Maria Fedorova, @lipid.bsky.social, Valerie O'Donnell, @holthuislab.bsky.social and @molcellbiophys-lab.bsky.social 🥳 Retweets = lipidlove

LIVESTREAM in half an hour about the new ancient DNA study published last week that changes our timeline for ancient cats. Should be a fun dive into the archaeology of cats www.youtube.com/watch?v=9byO...

New preprint from the lab!!🎉 We show that Asgard archaea ESCRT-III proteins can trigger membrane fission and reveal its molecular mechanism, offering clues to how these cells may have built internal compartments. But do these organisms even have these compartments? www.biorxiv.org/content/10.1...

I will be giving several talks this coming week at universities in Switzerland: Lausanne, Neuchâtel, Basel, and Bern. Hope to see some of you there!

What do you think? Real SDS-PAGE gel or AI-generated ?

Is it a flagellate? A tiny ball with tentacles? Contamination in my ciliate culture? NEW SUPERGROUP OF EUKARYOTES? Yes to all 4! Meet Solarion - just out in #Nature doi.org/10.1038/s415... Huge congrats to Marek Valt, Cepicka Lab & the star team! Very happy to be part of this project. #ProtistsOnSky

The first chapter of my PhD is finally out on @commsbio.nature.com We show that the transmembrane domain of SARS-CoV-2 Spike protein is not just a passive anchor to the virion surface, but a key player in the viral entry process.

We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.

And just when you thought things were settling down, the enigmatic Asgard archaea have another surprise in store! Cell cycle/life cycle stage-specific internal compartments with almost no eukaryote-derived clues as to how they might function. Beautiful tomography and microscopy - congrats all 🤩

Just published! We share an open-source workflow to measure membrane thickness from tomograms, including a tutorial with 3D visualizations. We analyze thickness variations across organelles and reflect on where to define a membrane boundary. @becklab.bsky.social #teamtomo rupress.org/jcb/article/...

I am excited to share our new preprint on the CAGE complex, a mysterious hollow protein complex that I first saw years ago while surveying Tetrahymena ciliary lysate www.biorxiv.org/content/10.1... #cilia #protistsonsky 🧬🧪

Are Asgard archaea the ancestors of eukaryotes? Likely not. Very insightful paper by @pforterrr.bsky.social

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge? It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door. Source code and a downloadable app to try it yourself […] [Original post on hachyderm.io]

Happy to share the latest work from the lab, led by @mudgal17.bsky.social‬, in collaboration with the Weis lab @ethzurich.bsky.social. How do nuclear membranes fuse during NPC assembly? We answer this question in our latest work, where we identify a new mechanism for membrane fusion… (1/13)

The peer review process is a flawless system that has no issues whatsoever /s

At times like these it's important to remember the 3 branches of science

It’s Mary Anning’s birthday, so time to share @katebeaton.bsky.social’s brilliant cartoon again.

"Dolphins call each other’s signature whistles if they get separated. Once, we played one of those whistles while the pair was still together. They responded with a totally different whistle. We call it the 'WTF whistle,' because it really did seem like that’s what they were asking." @science.org

...and big thanks to @jiwasa.bsky.social for making this amazing video to illustrate the strand-sliding mechanism!

Why are biological membranes asymmetric, with different lipids in the two bilayer leaflets? Discovered in the 70s, lipid asymmetry is linked to many cellular processes, but why the cell needs it is largely unclear. @pavelbarahtjan.bsky.social addresses this question: www.biorxiv.org/content/10.1...

New paper out! We discovered a tiny archaeon with the smallest known archaeal genome — only 238 kbp! Candidatus Sukunaarchaeum mirabile has almost no recognizable metabolic pathways and may rely heavily on a host to survive. It also represents a novel, deep-branching lineage in the archaeal tree.

Super weird debris covered thing ‘walking’ on a diatom from the charles river, with another diatom attached to it, along for the ride. For the life of me could not make out what it was. #sciart #microscopy #plankton

Those trying to understand the tariffs as economic policy are dangerously naive. No, the tariffs are a tool to collapse our democracy. A means to compel loyalty from every business that will need to petition Trump for relief. 1/ A 🧵 to explain his plan and how we fight back.

Video of the international student at Tufts being arrested by "federal authorities" in Massachusetts has been released and it's terrifying. They're not even uniformed officers. Just secret police thugs in hoodies and masks. From WCVB: youtu.be/PuFIs7OkzYY

biorxiv.org/content/10.1... Here’s a paper that was many years in the making. The idea that the climate can affect the thermodynamic mechanism of binding due to the temperature dependence of the entropy term is interesting- we see gradual shift in binding mode along evo trajectory…

NEW: Elon Musk’s X has suspended accounts of Turkish opposition groups, suppressing footage of anti-government protests. So, best we share all the footage we can here! This was last night’s massive demo against Erdogan’s government, which follows the arrest of his rival Ekrem İmamoğlu. 🇹🇷 #Turkey
