Dynamic protrusions mediate unique crawling motility in Asgard Archaea (Promethearchaeota)
Crawling motility is a hallmark of eukaryotic cells and requires a dynamic actin cytoskeleton, regulated adhesion, and spatially organized signalling pathways1–3. Asgard archaea (phylum Promethearchae...

🎄🧬 It’s December – time for an 'Immunocalendar': “CRISPR CRISPR KNÄUSCHEN”!
Every day we open a new door onto a different prokaryotic immune system, with extra love for archaeal hosts.
Crafted by the Zink Group within our department :)
Have a wonderful Christmas time! ✨

Our preprint is now published in PNAS! This came together thanks to a great collaboration with Antoine Hocher and a strong team effort from the Le Lab. Thank you to the reviewers and to everyone who helped improve it. I hope ParB aficionados will enjoy it.
