1. As we recently joined BlueSky, we want to repost this story for all newcomers! We sat down with @radler92.bsky.social to get more insight into the unique videos from his recent preprint on Promethearchaeota (formerly Asgard archaea). doi.org/10.1101/2025... (Videos and info below)

Are you a long-time fan of Archaea, an extremophile-phile, or are you simply curious? Either way, we have good news. We’re delighted to announce the 2026 EMBO Workshop on Archaea, 6–10 July. Sign up: meetings.embo.org/event/26-arc... We look forward to seeing you in Cambridge, UK Please repost!!

🚨 New paper out: Ecogenomics of Methylobacter 🦠 - three different MMOs to oxidize CH4 in single species - machinery for nitrogen, sulfur, iron, and hydrogen metabolisms - adaptations to low O2 conditions ... led by @wutkowska.bsky.social tinyurl.com/pmntwuk6 #MicrobeSky #pangenome

“Cultivation of Methanonezhaarchaeia, the third class of methanogens within the phylum Thermoproteota” by @kohtzarchaeota.bsky.social, Sylvia Nupp, and myself is out in Science Advances. 90% enriched culture of a methyl-dismutating thermoproteotal methanogen. #Microsky 🧪 tinyurl.com/bdcc3uzs

🧪🦠🌊 Curious on #niche differentiation of marine #AOA #Nitrosopumilus and #Nitrosopelagicus? #Urea is (part of) the answer! Very happy this fun study led by @mpimarinemicrobio.bsky.social is out: shorturl.at/wajjh Big shout out to Joerdis and Hannah for pushing this over the finish line!

🎄🧬 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 study of the evolution of the ParB NTP binding domain across the Tree of Life is now published! An awesome collaboration with @tunglejic.bsky.social led by @jovanakaljevic.bsky.social at the John Ines Center. Thanks to editors and reviewers. www.pnas.org/doi/10.1073/...

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. www.pnas.org/doi/10.1073/...

Fresh from our group, a new role for oxygen production in ammonia-oxidizing archaea: Oxygen production as an electron overflow pathway in ammonia-oxidizing archaea Congrats to Thomas Pribasnig for this great work! Check it out here: www.biorxiv.org/content/10.6...
