The lab CryoCube freezer’s alarm has been a little temperamental lately, so the undergrads renamed it the “Cry-ocube”

Archaea Power Hour returns next WEDNESDAY, May 20th, at 10AM EST / 4PM CET for the final installment of our spring semester seminar series!! We have two exciting talks planned for you so check your email for the Zoom link (coming soon) or visit our website (link in bio) for more info on how to join.
Almost archaea time!! Tune in tomorrow, Wednesday, May 20th at 10 AM EST / 4PM CET for the last seminar of our spring series 🥲. We have an exciting methanogen double feature in store for you! First up, Dr. Christian will tell us about his work enriching a novel methanogen from the Great Salt Lake!
Second up tomorrow, we have Anupkumar Rai who will tell us about his work biochemically characterizing an oxygen detoxifying enzyme that helps everyone’s favorite methanogen, Methanosarcina acetivorans, grow in the presence of O2. Check your email or Slack for the Zoom link!!
Last one of the semester!! Be there or be H. walsbyi 🥁

Reposting this as the deadline is less than a month from now! Spread the word!
🚨Hear, hear, fellow microbial cell biologists!🚨 🦠 Bacterial and Archaeal Cell Biology will be represented again at this year’s CELL BIO (ASCB-EMBO) meeting! The deadline to be considered for a talk in our Minisymposium is June 9. Help us spread the word! www.ascb.org/cellbio2026/
🎉 This is also a symbolic moment for the field: around 50 years since Carl Woese and colleagues first recognised Archaea as a distinct domain of life, fundamentally changing our understanding of evolution.

Second up tomorrow, April 22nd at 10AM EST / 4PM CET, Katy Weber will tell us about her interesting work to mechanistically characterize electron transfer in a reductase protein from Haloferax volcanii!! Visit the link in our bio for more info on how to join our community!!
Set your archaea alarms because APH starts tomorrow, Wednesday 4/22, at 10AM EST / 4 PM CET. We’ll start off with an intriguing talk from Dr. Alex Phillips about how droughts 🌵and floods 🌊 in the Great Salt Lake affect haloarchaeal inhabitants!! Check your email for the Zoom link!!

Today was also the lab’s first sampling trip, hunting for archaea around Davis!
Join me in welcoming the lab’s first graduate student, Jaylen Bush! That’s a well-deserved slice, Jaylen 🍕
Science Policy APH social edition next week!
Archaea Assemble!!! Archaea Power Hour returns next WEDNESDAY, March 18th at 11AM EST / 4PM CET. We will be having a special APH edition about science policy & reproducibility with the American Society for Microbiology and the protocol-sharing platform archaea.bio:
Second up this Wednesday, Jiayuan Cui will tell us about her exciting and rigorous research biochemically characterizing a radical SAM enzyme involved in archaeal monolayer lipid (GDGT) cross-linking. Check your email for the Zoom link or visit our website (link in bio) for more info on how to join!
Archaea Power Hour is back for our final session of the semester this WEDNESDAY, Dec. 17th, at 10AM EST / 4PM CET. We’ll start off with an intriguing talk from @fmacleod.bsky.social about his work uncovering unique intracellular membrane-bound compartments in an Asgard archaeon!!!
Lastly, for those at #CellBio25, we will be having a social TONIGHT at Little Gay Pub (102 S 13th Street) at 8 p.m.! Come meet the LGBTQ+ committee and let's celebrate another great conference! #outinstem #LGBTQIA #LGBTQ #queerinstem #cellbio #cellbiology #ascb #CellBio2025
Tomorrow!! Special Pohlschröder lab double feature, because we halove their work (going to pun hell now)

Stunning! Congrats @buzzbaum.bsky.social et al!
An Asgard archaeon with internal membrane compartments Brilliant study led by @fmacleod.bsky.social and Andriko von Kügelgen. Tight collaboration with @buzzbaum.bsky.social and lab. Congrats to all authors! www.biorxiv.org/content/10.1...
Rest in power Zara, you’ll be missed
The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor. The Zara Weinberg Leading Edge Cohort application is now open! Due Feb 2. www.leadingedgesymposium.org/apply/
Glad to share our paper out today @NatureEcoEvo: “Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor”. www.nature.com/articles/s41... #microsky #archaeasky
Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor - Nature Ecology & Evolution
Phylogenetic and biochemical analyses show a diversity of components of the DNA replication machinery in different Asgard archaea that contributed to the eukaryotic DNA replication machinery.
