1/25 New paper out in PNAS! We show that the fitness costs of reproductive specialization, where somatic cells give up reproduction, scale inversely with organism size. Larger organisms can afford far more soma, removing a key barrier to multicellular complexity.
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.

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.
Today we published a Correction on our 2023 @nature.com paper reporting the heimdallarchaeial ancestry of eukaryotes: www.nature.com/articles/s41...
Corrected paper: www.nature.com/articles/s41...
Importantly, the re-analyses of the corrected dataset are consistent with the original findings.
Comparative Genomics of Unicellular Eukaryotes (San Feliu, Spain):
Abstract submission is open, with a short deadline! comparativegenomics2026.com
Join us as we explore the most diverse, surprising, and still largely uncharted branches of the eukaryotic tree.
Microbial eukaryotes keep challenging assumptions about eukaryotic cell and genome biology.
Our upcoming workshop explores the frontier of protist genomics and how it shapes cell biology, ecology and evolution.
Please save the date! Talks, posters and ECR events

Beautiful work!
Happy to see our work published and glad to have contributed together with @maxraas.bsky.social ! Looking forward to all the projects that will come out of this work!
