And now it's out! Happy that PNAS selected for the cover this SEM image snapped by @samjlord.bsky.social, one of the most evocative visualizations of Euplotes that I have ever encountered. www.pnas.org/doi/10.1073/... Stay tuned for what is shaping up to be some fascinating follow-up in the lab...

If you want to know what 3′UTRs with long conserved sequence stretches do, check out our BioRxiv preprint doi.org/10.64898/202.... They form functional intermolecular 3′UTR-3′UTR interactions that enable co-folding of proteins to rapidly induce transcriptional programs.

Choice words from Dr. Szostak here. And while I am no Nobel Prize-winning scientist, I identify with the same quandary as an immigrant, moving here in 2009 and (proudly) becoming a citizen in 2023. I, too, don't recognize that country anymore 😢🇺🇸🧳🛫. newsletter.ofthebrave.org/p/im-a-nobel...

I finish books, even ones I don’t enjoy, but there was one I just couldn’t get through: gatsby. Today, a second book makes the list: Wuthering heights. Why are these so popular ? I guess I’ll never know

Finally published at long last (at least in the pre-view version). Explore the wild and woolly world of archaeal histones! Interactive archaeal histone graph incluced rdcu.be/fdFjv. Congratulations to first author Shawn Laursen

Very pleased to say that the paper version of our study examining the role of de novo DNMTs in cancer-associated hypomethylation is now out in @plos.org Genetics 🎉: doi.org/10.1371/jour... You can read more on the previous thread but here is a summary of the main updates! #epigenetics 🧵 1/9

First first-author paper out! 🎉 We show that the classically repressive mark H3K27me3 can be linked to active transcription through a newly identified reader complex 🤯 Really grateful to everyone involved in this project during my PhD! Thread below 👇

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

Long reads carry multiple small vars and SVs and their phasing. LongcallD is the only caller that tightly integrates germline/mosaic small/structural vars/MEIs and their phasing in a single C program. One command line to get competitive small variant calls and better SVs. Led by Yan Gao.

Happy 30th birthday to this paper published March 22, 1996, one of the studies that moved chromatin biology from correlation toward mechanism. Brownell et al. linked a transcription-associated Tetrahymena HAT to yeast Gcn5p, providing a biochemical link for chromatin modification to gene activation.

If you consider 'hiring’ AI instead of a graduate student, you're saying the quiet part out loud: PhDs are viewed as a PI's labor force not academics studying for an advanced degree... www.science.org/content/arti...

Fantastic collaboration w/ @dbikard.bsky.social @audeber.bsky.social @rayanchikhi.bsky.social labs led by @jmouradesousa.bsky.social : We assessed the rates of variation of anti-phage systems in P4-like satellites and P2 helper phages. Quick conclusion: Huge variation! We focus on 4 key questions/5

New preprint from the lab! We dig into the regulatory roles of TEs in the mouse placenta, with some surprising findings. Led by the awesome @smamante.bsky.social. Particular kudos to him for navigating the many twists and turns of the project.

🔔 New paper alert 🔔 www.nature.com/articles/s41... Some regions in the genome replicate early and some late, but the why and how remain poorly understood. DNA replication and 3D genome organization appear linked, raising the question if one may regulate the other? (1/n)

Hot from the press: Using single-cell chromatin accessibility and gene expression across ~300,000 cells, we show that prostate cancer dissemination involves phenotypic plasticity over clonal selection, with malignant cells converging toward an inflammatory-like state during lymph node spread.

@pravrutharaman.bsky.social got super intrigued about EZHIP/CATACOMB, previously identified as a histone H3K27M mimic of PRC2. You can read about her efforts here: www.biorxiv.org/content/10.6... We hope these analyses will help spur more analyses in this very cool gene! 1/
