Check out this interesting work from @katiegelder.bsky.social and @danbose.bsky.social describing how IDRs within CBP temper acetylation. Very cool work!

Really pleased to share the *final* version of @katiegelder.bsky.social's super work, profiling the functional roles of #IDRs in CBP. Published today 🎉 🔗https://doi.org/10.1016/j.celrep.2026.117109 #IDRs #condensates #transcription #CBP #generegulation #enhancers (1/7)

Incredibly proud to share our new preprint, lead by the Incomparable Rithika Sankar. Here we temporally dissect the role of FACT in mES cells, finding that FACT loss drives progressive deterioration of chromatin architecture, leading to transcriptional collapse. www.biorxiv.org/content/10.6...

I am excited to share a new review @cp-molcell.bsky.social written in collaboration with @tanjamittag.bsky.social , Mikayla Eppert, and Ambuja Navalkar where we review the current evidence for and against the role of density transitions in regulating transcription www.cell.com/molecular-ce...

CMU researchers have uncovered a bacterial vulnerability that could lead to a new class of treatments for antibiotic-resistant infections. Instead of killing bacteria, their approach targets pathways that control behavior. 🧪 #Biology #MolecularBiology www.cmu.edu/mcs/news-eve...

I am recruiting postdoctoral fellows to develop new research directions in the lab. We study transcriptional regulation through biomolecular condensates in development and disease, with an emphasis on first-principles and mechanistic discovery. Please repost or share with colleagues.

Really looking forward to presenting our lab's most recent work on transcriptional control and a surprising non-enzymatic function for RNA polymerase II

Unpause! I'm super happy to now be able to share the published version of our paper at Science Advances showing that: 1) active histone mods occur independently of transcription 2) transcription coordinates histone deacetylation at active promoters www.science.org/doi/10.1126/...

We’re excited to share our new work in Soft Matter: doi.org/10.1039/D5SM... We demonstrate how in vitro transcription can drive biomolecular phase separation — and how that phase separation in turn regulates transcription.

We are pleased to announce a new preprint by @mlweilert.bsky.social: “Widespread low-affinity motifs enhance chromatin accessibility and regulatory potential in mESCs” (www.biorxiv.org/content/10.1...). See summary and longer recap below: (TLDR; low-affinity motifs matter as pioneers!)

(1/10) How do diverse leukemia mutations converge on the same molecular program? In #RibackLab first manuscript @cp-cell.bsky.social, collaboration with @goodell-lab.bsky.social shows that disparate mutations rewire shared protein networks to form nuclear condensates called C-bodies.

CMU biologist @jhenninger.bsky.social is uncovering how RNA shapes gene expression and drives disease. His lab is developing tools to visualize transcription and design RNA-based therapies, paving the way for precision treatments for cancers like leukemia. www.cmu.edu/mcs/news-eve...

I am extremely grateful for the support from the Samuel and Emma Winters Foundation! This award directly supports our research on targeting RNA sequences as potential therapies in multiple disorders, including cancer.

Preprint! Inspired by condensates that form on specific DNA, we ask: can we design multicomponent fluids to form distinct condensates on diff. surfaces? i.e. perform classification by condensation ⚛️ 💻 exploiting phase transitions beyond compartmentalization! arxiv.org/abs/2509.08100 (1/2)

New preprint is up, led by former postdoc Braulio Bonilla. We know these remodelers regulate nucleosome positions and occupancy, but do they have a role in regulating higher order chromatin structure? We take a peek for BAF and INO80C. www.biorxiv.org/content/10.1...

Biomolecular condensates are critical for organizing cellular contents, but most studies focus on phase separation driven by salt, pH, or temperature. But what if intracellular movement also matters? Here, we explore motility-induced condensation in the cell. www.science.org/doi/10.1126/...

So fortunate to have Mike Rosen as the Keynote speaker at our 2nd Annual Steel City Condensate Symposium. The day was filled with fantastic science and discussion from biologists, chemists, physicians, and computer scientists from CMU, Pitt & NYU. Condensates continue to surprise us in many ways!
