Using fluorescence live imaging and an in vitro implantation model, we show that human embryo attachment begins with direct cell fusion via syncytin-2–MFSD2A interaction.

I was today years old when I learned that there is a superb (freely available) documentary from 1961 on early zebrafish development by J.V. Durden. collection.nfb.ca/film/embryon... (1/2)

Such a treat to be sitting in the room where @denisduboule.bsky.social is giving a talk @fsscr.bsky.social meeting in Lyon! Exciting and insightful science ahead 🤯🤘

Happy to present the final version of our Cadherin and gastruloid manuscript, online at @cp-cellreports.bsky.social. www.cell.com/cell-reports... Initially in BiorXiv (www.biorxiv.org/content/10.1...) 1/12

The number of international students arriving in the U.S. in August fell by 19% this year compared with last year — the largest decline on record outside of the pandemic.

Great talk by @emiliebrasset.bsky.social at #TECSHA on the regulation of piRNA production in germline vs somatic compartments of Drosophila ovary. Sophisticated mechanisms have evolved to control different sets of TEs, to the benefit (I think) of both host and TEs.

Hello World! Are you passionate about epigenomics and evolution 🧪🧬🐭🐵 ? Are you looking for a postdoc in a stimulating and inclusive environment ? Look no further... We are seeking creative postdocs for our ERC project EvoEpi @igred.fr ! 👇Details👇 tinyurl.com/PostdocEvoEp... Repost are appreciated

Ouiiiiiiiii Barney arrive !!! pintofscience.fr

J'ai besoin de votre aide ! On a recontruit une petite communauté ici pour @pintofscience.fr mais rien à voir avec ce qu'on avait sur Twitter 🫠 Si le cœur vous en dit, partagez le post d'aujourd'hui, suivez le compte, parlez en autour etc, ça nous aiderait BEAUCOUP à lancer #pint25 !! MERCI 🫶✨️

Hollande puis Macron ont mis à genoux les universités françaises. Depuis 2012, le budget annuel par étudiant a chuté de 22%. C'est un drame pour les jeunes, pour la recherche scientifique, et pour notre rayonnement international. Nous ferons mieux.

This is so far the best imaging of a E4.5 mouse embryo. From our M2 student Théo Boyer! Cleared with RapiClear (thks @alexandremayran.bsky.social). SOX2 is cyan, GATA6 is magenta, DAPI in gray. Playing with Napari. #fluorescentFriday #teamDICE #Development

Trump claimed the Biden administration spent $8 million "making mice transgender." The White House tried to back up this number with records of funding for research into cancer, asthma, and HIV, some of which used *transgenic* (genetically modified) mice.

One of my students wrote "sorry for my handwriting". Should I grant him extra points? Also, it was far from being the worst handwriting. #teaching #students.

A workflow for Tidyverse-based local synteny visualization: Good for visualizing local synteny across species, genotypes, or acorss regions of a genome. Can be used to showcase copy number variation. Still need to write the tutorial, but will be on my GitHub soon. #Genomics #DataVisualization
