🔬 A new study by EMBL researchers, published in @science.org, about the pre-ribosome assembly pathways inside intact human cells, reveals — at molecular resolution — in-cell structural snapshots of both ribosomal subunit precursors, the SSU processome and the pre-60S, and novel configurations.

🧬 1/ HP1α marks silenced heterochromatin, but how does it repress, and what happens when transcription is switched on? On mouse fibroblast chromocenters, HP1α stays bound, its barrier is local, and the domain reorganizes nanodomain by nanodomain. 👉 @cp-molcell.bsky.social doi.org/10.1016/j.mo...
Schematic of the two experimental systems. Left, activators recruited to chromocenters of wild-type and Suv39h dn mouse fibroblasts, with DAPI and anti-HP1α images showing HP1α enrichment and loss. Right, the U2OS 2-6-3 reporter array with an activator recruited alone or together with HP1α.

1/ Do cells use phase separation to adapt biosynthetic output to changing demands? In our new preprint, we show that under nutrient limitation, the nucleolus enters a reversible ‘hibernation’ state that slows ribosome biogenesis. See doi.org/10.64898/202...

(1/n) Super excited to share that our preprint is out today in @natsmb.nature.com with a new name "Integrated MINFLUX tracking reveals two distinct chromatin dynamics classes across cell types" and more than 2x more data: www.nature.com/articles/s41... See also MIT News news.mit.edu/2026/how-chr...

Spectral multiplexing is typically limited to 4-5 channels. Our new preprint introduces a framework that utilizes DNA barcoding and signal tuning to enable robust spectral unmixing and ground-truth benchmarking to achieve 15-plex subcellular profiling without cycling www.biorxiv.org/content/10.6...

Ribosomal RNA expansion segments mediate the oligomerization of inactive animal ribosomes
Cells down-regulate protein synthesis when stressed to conserve energy and shift resources toward repair. We found that in some mammalian cells, including neurons, stress also resulted in the formatio...

Last week marked the end of my postdoc at #RibackLab. I spent three exciting and productive years at BCM, but it’s now time for the next chapter. Thank you to @superscijew.bsky.social for being a great mentor and to my colleagues for all the fun and science we shared together!

Happy to share that my PhD project is finally published!🪱✨ Selfish genes are found across the tree of life. They can disrupt inheritance patterns and at the same time act as units for molecular innovation. Here we tried to answer one big question: how do selfish genes emerge in the first place?

(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.

Our lab's first preprint is out! I'm glad to be part of this project - take a look!
