I'm reposting this because I want to make a correction. In the thread below I mention using the -mset flag for testing site profile mixture models. But in fact you should use -madd flag. I'm sorry for this mistake.

1/ Our new paper in Systematic Biology "Modeling Site-and-Branch-Heterogeneity with GFmix" led by @cgpmcc.bsky.social describes improved ways to model compositional heterogeneity across both sites and branches—an important source of error in deep phylogenomics. doi.org/10.1093/sysb...

I'm looking for an enthusiastic student to join my team as a PhD candidate on archaeal genome evolution 🦠💻 Work in beautiful Utrecht, at @binfutrecht.bsky.social, an international group full of caring, amazing scientists, and with frequent cake breaks! www.uu.nl/en/organisat... Please share! 🙏

Hi all, we are experiencing technical difficulties with our original Zoom link. Here is an updated link: ucdavis.zoom.us/j/7241356569...

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.

🚨 Archaea alert 🚨!! We’re back this Wednesday, April 22nd, at 10 AM EST / 4 PM CET with two exciting research talks! You won’t want to miss this so check your email for the Zoom link or visit the link in our bio for more info on how to join the community 🦠

New #ISEPpapers #preprint by @deemteam.bsky.social: Re-evaluating the eukaryotic Tree of Life with independent phylogenomic data www.biorxiv.org/content/10.6... #Protists #Microbes #Evolution #Eukaryotes #TreeOfLife #Phylogeny #Phylogenomics #Bioinformatics #Algae

We have just published a short note on archaeal phylogeny: complex mixture models support a deep placement of Methanonatronarchaeia within Euryarchaea and indicate that three recently described groups (Halorutilales, Afararchaeaceae, and Ordosarchaeia) are actually the same. shorturl.at/5GMpU

So you are using IQ-TREE to estimate a tree for "deep time" phylogenetics using amino acid alignments. There is a lot of confusion about how to test model fit. Here are some suggestions.

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:

Beyond thrilled to share that our study has been published! This project encompasses years of work, including my thesis research on Asgard archaea in the @archaeal.bsky.social lab at @utmsi.bsky.social and @texasscience.bsky.social!!! #MicroSky #ArchaeaSky 1/12

Archaea Power Hour needs you 🫵! We are looking for presenters for our upcoming spring semester seminar series now! Tell us about your amazing archaeal research by submitting an abstract here: docs.google.com/forms/u/2/d/...

A reminder to sign up for the 2026 EMBO archaeal meeting im Cambridge: meetings.embo.org/event/26-arc.... Registration is open. We are looking forward to hosting you!

Calling all archaeal enthusiasts! 🔬🔥 From molecular machines to microbial communities, Archaea never fail to surprise us! We are excited to announce the 2026 EMBO Workshop on the Molecular Biology of Archaea, 6–10 July in Cambridge, UK! Sign up here: meetings.embo.org/event/26-arc... #ArchaeaSky

#NewResearch 🚨Out Now Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors, by @bbaker24.bsky.social @deemteam.bsky.social and team #MicroSky #Archaea 🦠 www.nature.com/articles/s41...

Very happy to finally have this out! Thank you to my awesome PhD supervisors and all the co-authors!!

This promises to be a cool PhD project with a very inspiring and nice PI!

It's that time again! Make sure to tune in THIS WEDNESDAY, March 12th, at 11AM EST (note the time change) / 4 PM CET to catch two exciting talks from @cjhines.bsky.social and Priyanka Chatterjee!! Check your email for the Zoom link or visit our website for more info on how to join (link in bio).

#Communiqué 🗞️ Le CNRS exprime sa solidarité avec les scientifiques exerçant aux États-Unis, où la liberté académique est aujourd'hui mise à l’épreuve. 👉 www.cnrs.fr/fr/presse/le...

Science, research & public health face unprecedented attacks in the U.S. We stand with our American colleagues & support the Stand Up for Science call. Join the global march tomorrow, incl. in Paris! 🧪✊ 📍 March 7, 13:30 – Place Jussieu 🔗 More info: standupforscience.fr #StandUpForScience

Exciting news! I'm looking for a computational biologist to join my lab at Wageningen University & Research! It's a 3-year postdoc position on Holomycota genome architecture and evolution. Spread the word! www.wur.nl/en/vacancy/p...

After 3 years of work, we are thrilled to submit this preprint. In collaboration with DEEM Team, we uncovered the complex interactions between haloarchaea, nanohaloarchaea, and their respective viruses and virus satellites. See🧵 www.biorxiv.org/content/10.1... #DPANN #ArchaealViruses #Satellite
