Thank you James !

That could be a good plan B if I don't get the ZF4 line ! Please send me the contact :)

Hello @zebrafishrock.bsky.social !
Do you know any lab that has the zebrafish cell line ZF4? It's quite uncommon to have a cell line from zebrafish. And we don't know any labs that won't with it ...

🚨 #postdoc to be hired in the Paluch Lab 🚨

If you know anyone experienced with and, more importantly, excited about nanoscale architecture of #actincortex and super-res & electron #microscopy do encourage them to apply👇

Amazing colleagues, can only recommend 😉

I am Iranian, we don't know each other, but we talk and we understand each other perfectly. The difference between you and your government is much bigger than the difference between you and me. And the difference between me and my government is much bigger than the difference between me and you. And our governments are very much the same."

Once again.

Very cool paper !

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

A brief 🧵 (carried over from the old place)

Same-sex marriage is legal in 39 countries Line chart showing the cumulative number of countries legalizing same-sex marriage from 2000 to 2025, with the y-axis from 0 to 40 countries and the x-axis from 2000 to 2025. The line rises from near zero in 2000 to 39 by June 2025. Annotations note: Netherlands was the first country to legalize same-sex marriage in 2001; South Africa has been the only African country to do so since 2006; Argentina was the first Latin American country in 2010; and Thailand became the first country in Southeast Asia in 2025. Caption says data are as of June 2025 from government sources and news articles. Data source in the footer: Pew Research Center (2025); website OurWorldinData.org/lgbt-rights; licensed CC BY.

Almost 40 countries have legalized same-sex marriage—

The Netherlands was the first country to legalize same-sex marriage in 2001. Since then, almost 40 other countries have followed suit.

You can see this in the chart, based on data from Pew Research.

Last paper from the Flipper saga... This time with enhanced plasma membrane targeting and fluorescence intensity. I have tried myself this new design and I recommend everyone to try out, especially in 2photon setups with deep imaging.

In our new paper in Chem. Sci., a final firework culminates with flippers that are not only as big and as beautiful as it gets but also solve a real problem and provide access to the imaging of membrane tension in living cells over longer periods of time.

As the President of the Beer Committee (yes...), I have moved the quest to #MakeBeerHourGreatAgain to the next level. By executive order, the #CzechPolka "Roll Out the Barrels" becomes the official beer #anthem. #Starobrnobitter Lots of foam, room for improvement. But it went fast... ❤️ @mpi-cbg.de

Okay, this is quite outstanding from Bedford Council.

Le fait de n’avoir aucune sympathie, et même une franche aversion pour LFI, ne devrait en rien empêcher de dénoncer les scandaleuses manipulations dont la dernière couverture de Marianne offre un exemple caricatural, comme pour venir illustrer celle, fort à propos, de Télérama cette même semaine.

I am super happy and honored to see some of my movies making it into the NYT. I hope everybody enjoys watching them go as much as I do!

Looking forward to meeting you!

Thanks for highlighting our work on combining AI-based organelle dynamics detection in phase contrast with fluorescence!

I’m thrilled to share that I will join @gustaveroussy.fr as a Group Leader!

Our objective: to understand how mechanochemical feedbacks regulate tumor dynamics and plasticity, with the overarching goal of bridging tissue mechanobiology and tumor pathophysiology using human organoids.

New method paper out today on FLIM analysis with Flipper-TR.
We discuss fitting strategies, common pitfalls, and quantitative interpretation for measurements.

Some snapshots from ongoing work with @cleocz.bsky.social & Liu Li:

Looking at labor economics textbooks over time, you see the discipline shift in the 1970s.

Earlier textbooks revolve around industrial relations & trade unions. Later ones centre on labor markets & human capital.

Researchers have discovered a little RNA molecule - small enough to potentially form spontaneously, yet sophisticated enough to begin to copy itself - that could explain how life on Earth began over four billion years ago, Science Director @rogerhighfield.bsky.social reports: https://bit.ly/3ZvPS6s

We’re excited to announce the opening of the Geneva Expansion Microscopy Facility (GenExM)!

GenExM is a full-service U-ExM platform (U-ExM, Cryo-ExM, iU-ExM), delivering nanoscale imaging.

Led by Dr. Olivier Mercey, GenExM welcomes academic & industrial collaborations.

How did life arise from simple chemical building blocks?

New #LMBResearch led by @edogia.bsky.social in @philholliger.bsky.social group has identified a small self-replicating ribozyme that could be the answer.

Here it is ! the discovery of a self-replicating RNA sequence ! Congratulations to all the authors ! it sounds like a major breakthrough in our understanding of the origin of life.

A small polymerase ribozyme that can synthesize itself and its complementary strand The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.
