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!

Excited to share our new paper in @cellreports.bsky.social that reshapes our understanding of chromosome organization's deep evolutionary roots! Our work dives into the origins of the machinery that structures our very genomes. 🔗: doi.org/10.1016/j.ce... #Genomics #Evolution #CellBiology #LECA

New vacancy in my team! PhD student position on microbial genome evolution, focusing on the evolutionary principles underlying bacterial genome architecture. Please repost and share with talented MSc students in #evobio, bioinformatics or related :) www.uu.nl/en/organisat... #MEvoSky #MicroSky

Check out exciting protist research in JEM! Holly Moeller et al. explore the feeding habits of Mesodinium rubrum and provide a tool for studying its cell biology and photophysiology in their open access paper in our March/April issue! doi.org/10.1111/jeu.... #protistsonsky

We must have been super lucky that contamination was all from different lineages to each Njord MAG and yet all from the same clade of unknown Asgard so that Njord form monophyletic groups within Asgards in individual gene trees.

I'm pleased to introduce our new paper rooting the eukaryote Tree of Life (eToL) that resulted from a collaboration led by PhD student Kelsey Williamson and a large group of collaborators doi.org/10.1038/s415...htt

🚨 New paper alert! 🚨 A robustly rooted tree of eukaryotes sheds light on their deep evolutionary ancestry—suggesting that the Last Eukaryotic Common Ancestor (LECA) may have had an excavate-like cell architecture. 🧵🔬 (1/) www.nature.com/articles/s41...

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1... A little thread below 1/n

Dear US scientists, We've been hearing a lot of questions of the form "Why aren't universities doing anything!? They need to speak out!" We can explain. It's bad news. We're on our own. But understanding why can help us all figure out our plan. Read along in thread 1/x 🧪

📢Call for Papers!📢 Applied and Environmental Microbiology is actively seeking submissions on the topic Anaerobic Microbiology. We welcome reviews and new research insights into strict and facultative anaerobes (archaea, bacteria, eukarya, viruses). Learn more: journals.asm.org/journal/aem/...

Please share! Applications due Dec 15th for a starting date in Sep 2025.

Understanding the origin of eukaryotic cells is one of the biggest puzzles in biology 🧩 As genomic data expand, painting a clear picture of LECA requires analytical resources and a commitment to data sharing. This paper led by T. R. emphasizes a community-driven approach to tackle this complexity.

This really is an excellent paper. It shows that plastid protein import machinery can be inherited through serial transfer, and that we should not expect additional membranes in tertiary plastids. In other words, serial transfers got easier to explain www.sciencedirect.com/science/arti...

Symbiosis nerds! Some of you might have seen a smattering of recent posts about papers in PLoS Biology, but it's worth looking at the entire special issue, called Symbiosis Across the Tree of Life (edited by Richards and Moran). There are so many interesting reviews, comments, etc. type things here!

Greetings to new followers! For those with only a sketchy, starter-pack sense of me, here's a quick run-down. I write about life for the New York Times. Today is the 20th anniversary of my 1st story there! I write on evolution, genomes, pandemics, brains, etc. www.nytimes.com/by/carl-zimmer 1/8

Microbial people! Especially postdocs and maybe some assistant professors who are feeling antsy ... the University of Montana is doing a search for a microbiologist! This is a great department, in a great place. (I worked there for 10 years, loved it, ping me with Qs) apply.interfolio.com/159494

If you... like me... have found a lot of cool/relevant starter packs only to lose them again, here is a really useful tool - search starter packs: blueskydirectory.com/starter-pack... 🧪

I've imported all my posts from X using blueark.app, which seems to have worked well! (except it doesn't import any of the comments and reactions, so it makes you look a little bit like you're talking to yourself 😅)

Genomics, evolution, and more starter pack! Help build community with this starter pack. This list is currently incomplete. Want to be included? Reply and I will remedy that! go.bsky.app/JjvzkWU

We are searching for a postdoc to join our team, focused on anaerobic ciliate-methanogen symbiosis. Please share widely!

Highly recommend reading the Dispatch by @freejakoba and @Ryan_Gawryluk. It's a thorough and well-written perspective on the relevance of our findings! https://www.sciencedirect.com/science/article/abs/pii/S0960982224008510?via%3Dihub

Happy to present the outcome of a fun project carried out hand in hand with David Moreira. Did you know there's mitochondrial genome out there just as gene-rich as those of of jakobids? Why do we care, one might ask? Say no more! A thread...
