Pierre Bourguet (@p-bourguet.bsky.social) has been awarded a Marie Skłodowska-Curie Postdoctoral Fellowship for the RegulatoryTEmbryo project at IBMP! His project explores how transposable elements shape plant embryogenesis and rewire developmental gene networks. #MSCA

Which transcription factors control transposable element expression during zygotic genome activation? Gain-of-function screen by @metorrespadilla.bsky.social and coworkers identifies TBP as direct regulator of mouse endogenous retrovirus-like elements link.springer.com/article/10.1...

Drosophila border cells are beautiful to watch… but far from easy to image. Kudos to the brave and skilled @vitoryang.bsky.social, who took on the challenge of establishing border cell migration imaging in the lab! His movies are astonishing, and now our first-ever study on #cell #migration is out!

Such sad news. He was a major contributor to small RNA biology — an inspiring scientist and such a kind collaborator. I have no words 🥲 www.cruk.cam.ac.uk/news/in-memo...

Germ cells have their own versions of core transcription factors and fertility depends on them. We're hiring a PhD student to figure out how! 📢 Fly genetics + proteomics + genomics. Fully funded. Aarhus University 🇩🇰 Deadline May 1 👇 Please share with anyone who might be interested!

Love Drosophila genetics — this journal club was a great way to share that enthusiasm and pay tribute to the pioneers of transposons regulation 🪰 How classical genetics uncovered key determinants of TE silencing #transposon @igred.fr @igred.fr 👇👇

🆕 New paper out with Jean-Luc Imler and Rune Hartmann in EMBO journal. We dissect mechanisms of antiviral immunity and how STING is activated by FADD and DREDD during viral infection in Drosophila melanogaster. link.springer.com/article/10.1...

We were all very sad to learn the death of Pierre Capy. Pierre was a professor at University Paris Saclay, in the 1990s, he started a group working on the evolutionary genomics of transposable elements; this group is still very active today. He was a great teacher, mentor, and colleague.

Pierre Capy était un généticien, un drosophiliste, un acteur majeur dans l'essor de la génétique des éléments transposables en France. Très impliqué dans l'administration de la vie scientifique, il a aussi été directeur du laboratoire LEGS (actuel @EGCE), et un des fondateurs en 2016 de @IDEEV.

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9
