Hello World ! Its pre-print time ! Awesome collaboration led by Michel Cohen-Tannoudji (not on Bsky) and the one and only @deborahbourchis.bsky.social. #BFF We solved the molecular mechanism underlying a mysterious hybrid incompatibility in mice: the DDK syndrome. 🧵🍿 www.biorxiv.org/content/10.6...

The Bioinformatic analysis of TEs is almost full! If interested in TE, you cannot miss this course with such an amazing team of instructors @valentinapeona.bsky.social @ritarebollo.bsky.social & @clementgoubert.bsky.social www.physalia-courses.org/courses-work...

Very happy to see our Nature Reviews Genetics article on programmed DNA elimination across eukaryotes out! A fantastic collective effort with an amazing group of colleagues, born from inspiring discussions at the Fondation des Treilles. rdcu.be/tmvKgsPZNhBa @laurarossevo.bsky.social

Hi! Working with friends, best thing ever! Bonne lecture! #TEs&Friends

What if transposases are already transcription factors in disguise? Our new preprint shows that transcriptional regulatory activity is an intrinsic property of transposases, revealing a direct route for their domestication into transcription factors. www.biorxiv.org/content/10.6...

The last chapter of my PhD work is now live on MBE. This has been an incredible project, combining genomics, proteomics, as well as transcriptomics that resolves total mRNA from ribosome-associated mRNA (which we infer to be in the process of translation).

Our study published today @science.org shows that X-chromosome inactivation (XCI) attracts L1 mutations to the human X chromosome: doi.org/10.1126/scie... With outstanding Perspective from @aurelien-doucet.bsky.social & @retrogenomics.bsky.social: doi.org/10.1126/scie...

Our new paper is out in @nature.com! We uncovered how a naked mole-rat queen 👑 controls an entire colony: a natural contraceptive scent that suppresses reproduction in other females! A remarkable mammalian parallel to bees and ants! 🐝🐜 @garyrlewin.bsky.social youtu.be/enfv3zJrWKM?...

Horizontal gene transfer (HGT) in ants - several likely underpinning functional innovations, primarily by mediating immune-system adaptations or facilitating nutritional niche expansions academic.oup.com/gigascience/... #biodiversity #genomics

Yesterday, @nicolasparisot.bsky.social received his "Habilitation à Diriger des Recherches" in front of a jury composed of C. Braquart-Varnier, O. Duron, M. Sicard, T. Lefebure, and Z. Haichar. He brilliantly presented his research at @inrae-umr-bf2i.bsky.social. Congratulations 👏

Out today in Nature Microbiology: a paper that started in 2021 with an email from @sullivan-lab.bsky.social. Subject line: "Crazy ideas". www.nature.com/articles/s41... 1/23

Major development in the #Transposon world! Repbase is joining the Dfam project and becomes open-access! link.springer.com/article/10.1...

Yes!!!!

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...

Our latest publication is now out at Genome Biology! link.springer.com/article/10.1... We uncover a unique association between a H3K27me3 reader complex and active transcription. A thread with our key findings: (1/8) #TEsky #Polycomb #transcription #smallRNAs

This week @annazaidmanremy.bsky.social and @jesuxueml.bsky.social were at the EMBL symposium entitled “The cellular mechanics of symbiosis: sensing friend from foe” @events.embl.org. They gave excellent presentations which sparked lively discussions! #EESSymbiosis #SymbioSky

Next, Jesus Uxue Mendez Leyva on a recently acquired bacterial endosymbionts in weevils. Their genomes have lots mobile genomic elements suggesting that they are undergoing a period of genomic instability, and the genes associated with TEs might play a role in the symbiosis #EESSymbiosis

Following the #EESSymbiosis @events.embl.org through Bluesky! Keep posting! @annazaidmanremy.bsky.social gave a wonderful talk yesterday (I've been told!), & @jesuxueml.bsky.social will take the floor today! Have fun, I'm not jealous at all #FOMO And go Mobile Genetic Elements <3 #SymbioSky

We are looking for a Postdoc to join our lab at @oxfordbiochemistry.bsky.social. This is a dry-lab focused post on the computational analysis of long read single-cell sequencing data to understand the role of transposable elements (TEs) in early development. my.corehr.com/pls/uoxrecru... #TEsky

🚨📢📄 Article in press in Genome Biology doi.org/10.1186/s130... We introduce panREPET, a reference-free pipeline to detect shared transposable element (TE) insertions across pangenomes and retrace their evolutionary dynamics #TEsky 🧵👇

Everything you always wanted to know about TE classification ! @nico971.bsky.social and @johannconfais.bsky.social present RepetDB a TE database to support your science at GDR #MobilET meeting.

Bravo Anaïs!

Happy to share the results of a long-haul post-doc project, now online @science.org, aiming at understanding the rules of transgeneration epigenetic inheritance over TEs in plants and its extent and impact in nature. More below! doi.org/10.1126/scie...

Mais pourquoi faut faire des HDRs? Pourquoiiiiii? 🤢

Hi! We are looking for a PhD to work on the cross talk between transposable elements, insects and intracellular bacteria on the bioinformatics side. The PhD would be supervised by @mariefablet.bsky.social and myself along with @nicolasparisot.bsky.social Deadline December 2025! Please share! #tesky

📣 #OurLastPaper is out! A quantitative metabolic model of the obligate #aphid symbiont, #Buchnera aphidicola. This work also provides a model of the life stage-specific provision of nutrients from the bacterium to the host. #SymbioSky www.sciencedirect.com/science/arti...

📣 #OurLastPaper is out! This study explores the functional specialization of the symbiont-bearing organ in the rice weevil. Using microdissection coupled with dual RNA-seq, we revealed different cell types, each with distinct host-symbiont molecular dialogues. #SymbioSky doi.org/10.1186/s401...

A little late to share, but still thrilled 🤗! What started as two independent stories, one in Clermont-Ferrand (@igred.fr) and one in Cambridge (Hannon’s group @cruk-mi.bsky.social ), turned into a joint adventure to decode how Rhino picks its favorite piRNA clusters. When forces unite… 👇👇👇
