Katja Petzold @katjapetzold.bsky.social · 01/10/2026We’re looking for postdocs to explore RNA dynamics in biologically relevant conditions in an international and genuinely curious research team. If you’re interested in RNA changing its shape to perform its function (even inside a living cell), we'd love to hear from you. Details: petzoldlab.competzoldlab.comHome 057

We previously showed mouse ectoderm can be targeted by amniotic injection, enabling cell-specific manipulation, lineage tracing, and knockouts. But how to reach mesoderm? 86631
Reposted by Katja PetzoldMagdalena Skipper @magdalenaskipper.bsky.social · 02/07/2026Too many of us repeat the statement that trust in science is falling. Is it really the case? The data don’t support this conclusion in a straight forward way. Science may have an influence & comms problem more than a trust problem, in fact… but it’s complex 👇🏻 🧪 www.nature.com/articles/d41...nature.comHave people stopped trusting science? The data tell a surprising storySome say there’s a global crisis of trust — but research reveals where the real problems lie. 02620

Dynamics, computation and what brings the future! Big thanks to Geerten Vuister & @ccpnmr.bsky.social team and hopefully many more years of this well needed initiative for the #NMR community 👏👏👏 051
Katja Petzold @katjapetzold.bsky.social · 23/06/2026I still have trouble to believe it #ERCAdG 🤩! We celebrated it a lot!! Big thanks to all future and current lab members and the evaluators!

Katja Petzold @katjapetzold.bsky.social · 11/05/2026Imagine if one of RNA’s most common 3D contacts could switch off and on. We identified the A-minor switch that can reversibly “escape” their tertiary contacts, revealing a dynamic regulatory layer in RNA structure (shown by NMR & Cryo-EM and assayed in ribosomes). #RNA #NMR #dynamics #ribosomebiorxiv.org 162

Katja Petzold @katjapetzold.bsky.social · 10/10/2025Do current publishing and carreer assessment practices limit scientific progress?
