New preprint! Cell division has to happen at the right place but how Archaea pick that place is unknown. We now identified a three-protein system, Dip, that positions the divisome at midcell in H. volcanii and is broadly conserved across Archaea. A thread 🧵 www.biorxiv.org/content/10.6...

New funding opportunity from the Symbiosis in Aquatic Systems Initiative. We’re inviting teams of two researchers to pursue ambitious, high-risk projects advancing aquatic symbiosis (marine + freshwater). Open globally. Details + how to apply:  moore.org/SymbiosisRFP #RFP #AquaticSymbiosis

Really excited to share our new paper from @ibe-warszawa.bsky.social protist team! 🎉 We dive into protist symbioses and show how these interactions shape ecosystems and have played a key role in the evolution of eukaryotes 🦠
