New paper! How do RNAs "know" where to go inside a cell? We dug into the sequence elements that route RNAs to the right place. It turns out that, in mammals, they're surprisingly massive (>200 nt), multipartite, and wonderfully complicated. 🧵

We are thrilled to announce the 2026 Zara Weinberg Leading Edge Fellows! 40 remarkable postdocs pursuing transformative research in biological/biomedical sciences. This is the 7th Leading Edge cohort and we are so excited to welcome them! www.leadingedgesymposium.org/fellows/

Exciting new work from the lab led by @lagiven.bsky.social & co-advised by @tododge.bsky.social mapping pigmentation variation in the swordtail X. nezahualcoyotl! Spotting variation is linked to xmrk but embedded in complex genomic regions that Tris & Lyle tackled with UL nanopore: shorturl.at/Ljw1z

Help please! We need to do some large(ish) cell culture inhibiting E-cadherin with a monoclonal antibody. Does anyone have the DECMA-1 hybridoma cell line so we could purify our own antibody? or a similar monoclonal that would do the job. Any help greatly appreciated, just DM me. Please repost!

Excited to share this new pre-print from the fantastic @kelsiehunnicutt.bsky.social! Kelsie put together a thoughtful and thorough review on hybridization in animal evolution: ecoevorxiv.org/repository/v.... She tracks notable shifts in perspectives on the study of hybridization through time.

Very excited to share our newest findings! A very long team effort pursued by multiple team members -to frantically reproduce everything over and over-, we show mTOR-Polycomb synergy at promoters of developmental master regulator TFs in ESCs prior to their expression. www.biorxiv.org/content/10.6...

First human blastoids since I started my lab at Max Planck! Yes, I´m thrilled! 🔬

Looking forward to it!

Ever notice that when one gene is disrupted, its orthologs get upregulated? This phenomenon, known as transcriptional adaptation, has been controversial and mysterious - glad to see that we are starting to learn how it works.

New Year, New Paper!🎊 Pervasive cis-regulatory co-option of a transposable element family reinforces cell identity across the mouse immune system www.biorxiv.org/content/10.6... Centerpiece of Jason Chobirko's PhD, talented PhD student co-mentored by Andrew Grimson & me. Really excited about it!🧵

🚨New paper from our team on our favorite sex locus ANTSR! 🚨New collaboration with @hugodarras.bsky.social , led by our talented @chuanxinyu.bsky.social, we show that ants, bees and stinging wasps share an ancient sex locus, a suspicion we had when we first found the locus in the Argentine ants!

Happy to begin the year with the publication of a Journal Club article - Programmed ‘DNA splicing’ removes transposons from genes. rdcu.be/eXBym
