🎉 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.
Bridging the lipid divide: archaeal ESCRT-III binds phosphoinositol and polarises the cytokinetic membrane www.biorxiv.org/content/10.6...
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!!
🚨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/
🚨 🦠 Don’t miss us next Wednesday!
Haha maybe some find it fun too 🫠
Haha indeed. But we want to know *who’s* out here!
Today was also the lab’s first sampling trip, hunting for archaea around Davis!
Thank you, Flora!
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!
Out now!
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!!!
“Happy Holidarchaeays” to you too
Sure, we have plenty beautiful examples to share! Who should I contact?
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)
Archaeasalutations!! Archaea Power Hour is back tomorrow (Wednesday) at 10 AM EST / 4 PM CET!! Check your email for the Zoom link or sign up to join our mailing list here: docs.google.com/forms/d/e/1FAI…. Check out the two exciting talks we have planned for you:
Stunning! Congrats @buzzbaum.bsky.social et al!
Rest in power Zara, you’ll be missed
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
Don’t miss the first APH meeting of the season this coming Wednesday!
Welcome to our first postdoc in the ACO Lab, Andy Garcia! 🎉
Supporting each other as #newPI is very important, and @antonioserapio.bsky.social is great at it
🚨 🚨 🗓️ The deadline to submit your abstract for the #ASCB2025 meeting in Philadelphia is this Wednesday, September 3!!
Dyche Mullins and I are hosting the session “Cell Biology at the Extremes”. Thermophiles, psychrophiles, tardigrades, giant bacteria… now is your time to shine!! 🚨
New hot fluorescent tag dropped!
Thank you!
We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social!
