RNA detectives on a mission to catch RNA in the act of folding & uncover how proteins helped. Run by graduate students / postdocs. Dr. Sarah Woodson’s Lab at Johns Hopkins University.

Congratulations to historian Richard Kagan, neuroscientist Ulrich Mueller, political scientist Vesla Weaver, and biophysicist Sarah Woodson on being elected to the American Academy of Arts and Sciences. hub.jhu.edu/2026/04/30/a...

Our new paper is out! Using 19F NMR, we show that Hfq rewires the conformational dynamics of a model sRNA in a site-specific manner. Uridines at the rim undergo faster exchange (~100 μs) than those in the proximal pore (~300 μs). Congrats Elise! 🎉🎉 www.sciencedirect.com/science/arti...

🎉 We’re excited to officially kick off the ERC Synergy project, snoOPERA, with Anthony Henras, Brigitte Pertschy, and Roland Beckmann! 🎉 Bringing together labs across 3 European countries and the US, we aim to uncover hidden functions of snoRNPs in ribosome assembly. Go team! tinyurl.com/2e5r57b5

Congratulations to Anthony Henras, winner of the ERC Synergy 2025 grant!

Parmi les 66 projets sélectionnés par le Conseil européen de la recherche, Anthony Henras et l’équipe EukaRiBio (MCD-CBI) sont lauréat d’un des 13 projets du

🚨New paper alert! Using single molecule TIRF microscopy, we show that Nop1 destabilizes RNA structure via transient, nonspecific interactions — until specific assembly of native ribosomal complexes takes over. Congrats, Wilson! 🎉 academic.oup.com/nar/article/...

Fibrillarin/Nop1 perturbs RNA folding and assembly independently of liquid–liquid phase separation

Abstract. The liquid–liquid phase-separated environment of the eukaryotic nucleolus is proposed to benefit ribosome assembly by chaperoning rRNA folding an

Our new paper is out in PNAS! We show that competition for binding to the Hfq matchmaker disfavors mismatched sRNA-mRNA combinations while allowing matched sRNA-mRNAs to form stable pairs. Kudos to Jorjethe Roca and Yi-Lan Chen for their fantastic work on this problem! doi.org/10.1073/pnas...
