Huge congratulations to Thomas on this well-deserved award. His PhD defense last week was outstanding too - a great moment. He’ll on the lookout for a postdoc position soon…spread the word!

Please re-post: Interested in chromatin and its evolution? Good news! There's still time to join us in beautiful Catalonia (9-12 Dec) to discuss eukaryotic, bacterial, archaeal, and viral chromatin and how it all hangs together meetings.embo.org/event/24-evo... Abstract deadline: 30 September

📢 Institut Jacques Monod Seminar 📅 September 18th 📍 Institut Jacques Monod Invited by @sandraduharcourt.bsky.social’s lab, Peter Andersen ( @germline.bsky.social ) will give the IJM Seminar "Running to stand still – Recurrent innovation of animal germline genome regulation" ➡️ buff.ly/yaK2kTQ

New online: Binding of heterochromatin protein Rhino to a subset of piRNA clusters depends on a combination of two histone marks

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social! www.biorxiv.org/content/10.1... #Chromatin #Asgard #Archaea #cryoEM

I add an amazing time last week at the Epigenetics 2025 meeting from the @gensocuk.bsky.social in sunny Belfast! Great discussions and insights on my PhD project! Also very honored to have been awarded the best poster prize!

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬 But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯 Our new study reveals how retrotransposons invade the germline directly from somatic cells. www.biorxiv.org/content/10.1... A short thread 🧵👇

🚨Cool new study from the lab neighbours! They look into two PAX proteins that orchestrate neuronal diversity!

Our paper on Alternative epigenetic states of Arabidopsis Transposable Elements is finally out in Genome Biology ! rdcu.be/d6Yly

Our #Paramecium artwork is featured on the cover of #NAR! doi.org/10.1093/nar/...

Work led by graduate student @trinitycookis.bsky.social and coauthors Alexandria Lydecker, @paulsauer.bsky.social, and @kasinath-lab.bsky.social is out today where we looked at the inhibition of PRC2 by histone PTMs associated with regions of active transcription. www.nature.com/articles/s41...

A brief overview of my latest project in the Duharcourt lab, highlighted by @cnrs.bsky.social and a sneak peek in the head of an artist (aka my sister) inspired by Paramecium.

We have had multiple discussions about why people have not previously observed the very dramatic reduction in transcription upon PNUTS depletion. So I looked at our own TT-seq data and analysed it without including the spike-in. The numbers speak for themselves! Spike-in calibration is important!

Very cool new paper from the lab, delving into sRNAs selective degradation enabling TE control! Congrats @oliviacharmant.bsky.social 🎉🎉

Please see our paper in Nature on read-write mechanisms of H2AK119 ubiquitination by Polycomb repressive complex I. Congrats to the whole team, especially Victoria and huge thanks to our collaborator JP Armache! Also big thanks to Mark Foundation for Cancer Research for the support! rdcu.be/dZ5HZ
