Absolutely delighted to share the fantastic PhD work of
@1995dana.bsky.social
that is very dear to my heart ❤️ (pun intended).
🧬 She reveals how L2/MIR transposable elements have been co-opted to safeguard cardiomyocyte identity 🫀
📖 Check out her thread and bioRxiv preprint for all the details! 🔗

New preprint of @trono-lab.bsky.social and my PhD work!
By modulating SWI/SNF remodeling at ancient transposable elements - LINE/L2s and SINE/MIRs, a "noncanonical" KZFP called ZNF436 protects cardiomyocytes from losing their identity.

🚨 New paper alert on telomeres! 🚨
Something different from the group! Thanks to Yuxin, a talented student in the lab, we used long-reads in 75 human trios to study telomeres and their inheritance.

We lost another Gem of a scientist:

His work inspired so many of us, such a brilliant mind and a kind human

Apart from rewriting our fundamental understanding of cell identity, his love for science is equally legendary

New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains

3rd lab meeting I’m presenting at this year! After two during my sabbatical on my experiments (Helaine & Mekalanos labs), today finally in MY OWN lab 🎉
So much fun to share new work done w/ fantastic technicians Laurie, Sandrine, Loriane & bioinformatician Alexandre.
Bonus: cake served by the lab 🍰

First-grader raises $1,000 for axolotl research, meets her scientist hero — and maybe gets taste of what she wants to do when she grows up

Really excited to share our latest work led by @mattiaubertini.bsky.social and @nesslfy.bsky.social: we report that cohesin loop extrusion creates rare but long-lived encounters between genomic sequences which underlie efficient enhancer-promoter communication.

Very happy to have contributed to this review on "non-CG" #methylation in animals now out in @natgenet.nature.com. Working again with @obog.bsky.social and Tirsa is always a pleasure. We think this not so well studied form of methylation should be more widely considered, please read: rdcu.be/eFAEk

Legend David Baltimore died yesterday. He understood the way things should work: "the real contribution of MIT is that it doesn't take itself too seriously. It takes ideas seriously, but the people are relatively informal. They are not self-aggrandizing the way academics can be."

Here are all the talks I attended and sketched at #ESEB2025 ! Only a fraction of the 642 speakers at the conference 😮

I had an absolutely amazing week chatting about lots of fascinating science
