Well worth a read by @kashhill.bsky.social & @dylanfreedman.nytimes.com: everyday users risk spiraling into delusions during long AI chatbot sessions. Anyone who’s worked with AI knows this is inevitable without strong guardrails. #AI #GenAI #MentalHealth #EthicalAI #ResponsibleAI #AIRisk

Presenting my poster today at the #GRC Protein Engineering. Come have a chat about defluorinase engineering for organofluoride degradation at #37, Monday and Tuesday!

Happy to attend the Gordon Research Seminar and Conference on Protein Engineering this year, held in Bryant University. Looking forward to connecting and having inspiring discussions! #GRS #GRC #ProteinEngineering

With #PFAS and other organofluorides wreaking havoc, we set out to engineer natural defluorinases for man-made organofluorides. All credit goes to the amazing @suzannejansen.bsky.social, who has outdone herself in this project! (1/5) www.biorxiv.org/content/10.1...

Preprint alert! With #PFAS contamination becoming an environmental crisis, we dared to engineer natural defluorinases towards degradation of (un)natural organofluorides. How? Check out our robust growth-based selection platform here: www.biorxiv.org/content/10.1... thanks to @mayerlab.bsky.social !

Had an excellent and inspiring time at NWO Life 2025, fascinating to see how Life science affects so many different research subjects! It's fun to see how Darwinism is still very much alive in these circles 😛

📢📢📢 PhD Opportunity! Join our research group at RUG! We're seeking a motivated PhD student for a project on biocatalytic cascade processes combining natural and designer enzymes, supported by machine learning. Click below to learn more — and feel free to share! sites.google.com/rug.nl/roelf...

I've been selected as a speaker at #NWOlife2025 on May 28th! Sneak peek: how can we use life (or death) to elicit better defluorinating enzymes toward organofluorine degradation? Looking forward to discuss all the interesting ways that life is involved in your research!

This is so cool. I hope they make it.

Season's greetings from Roelfes and Mayer groups! Wishing our colleagues, collaborators, and the entire community a joyful holiday season and a prosperous New Year ahead! 🎉🎄✨🧪
