1/11 🤩Sooooo happy to see this work on a new new group #algae. Looks like #centrohelids - predatory ancient eukaryotic lineage sometimes harbor vertically-inherited plastids from #dictyochophytes. Amazing work, @annewalraven.bsky.social, glad to be on board! More below:

Very excited that the preprint of the main paper of my PhD is now out! We show that Meringosphaera is the first centrohelid with permanent plastids: doi.org/10.64898/202... @zlatogursky.bsky.social, @pjkeelinglab.bsky.social, prof. Rachel A. Foster, and @fburki.bsky.social #protistsonsky

I wanted to like QED's new 1% preprint ranking. I really did. But the more I looked at the data, the more uncomfortable it made me. Here is my full peer review. open.substack.com/pub/blekhman...

1/9 For years, debates about microbial biogeography have sometimes been framed as a choice. Either microorganisms are everywhere. Or geography matters. But what if that is a false choice? @ibe-barcelona.bsky.social @icreacommunity.bsky.social @prbb.org @csic.es #protistsOnSKy

My last pic of the organizers closing out the inaugural session of the #MicroSEA course, dedicated to hands on single cell methods with micro-eukaryotes. It was an honor and a pleasure to share. Bravo @johandecelle.bsky.social @mjamy.bsky.social @protistwtmostest.bsky.social and other organizers!

10/10 Perhaps aggregation is not an evolutionary dead end after all! Perhaps it was one of the evolutionary experiments from which animal multicellularity emerged. Link: www.nature.com/articles/s41... @icreacommunity.bsky.social #AnimalOrigins #Evolution #Multicellularity

1/10 For decades, cellular aggregation was considered an evolutionary dead end. Cells could come together temporarily. But complex multicellular organisms like animals? Our study, led by JP Gerdt, with Ruibao & @jennahed.bsky.social suggests it may be time to rethink that🧵 #ProtistsOnSKy

Very proud about the first true citizen science based biology preprint ever lead by my research group, and yes, I did field work to assess the insect biodiversity of our small village in southern Crete: www.biorxiv.org/content/10.6...

Today marks 30 years since we identified the apicoplast, a relict plastid in human and animal parasites (PMID 8632819). Apicoplasts are the target of the widely used antimalarial prophylactic doxycycline, which has saved many thousands of malaria infections.

Our method, savont, for generating amplicon sequence variants (ASVs) for long-read amplicons is now on bioRxiv. Work with @lh3lh3.bsky.social and help from @mkddueholm.bsky.social and team (Marie Riisgaard-Jensen, @kirk3gaard.bsky.social, Kasper Skytte Andersen) github.com/bluenote-157... 1/6

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.

Can vouch! I worked a lot with Dani and he's one of the most thoughtful, generous scientists I know. If you're into archaea and want a PI who invests in his people (and yes, the cake breaks are real), apply. You won't regret it.

Excited to say that my new paper with @maxlechte.bsky.social (and others not on bluesky) has come out in @nature.com! Study of sediments, geochemistry and fossils from rocks 1.75 to 1.4 billion years old indicate that the oldest known #eukaryotes were aerobic and benthic! #protists rdcu.be/fjNgL

I really don't think the RETRACTION of this article is getting enough attention! Both for how Nature will seemingly publish anything if there's an ulterior capitalist agenda behind it, and for how this paper was used to beat people into submission to include LLM use in classrooms.
