Another #notTHECover unfortunately. But this gorgeous, Tron-like vibe, drawn by the amazing @munafomarzia.bsky.social for our recent #ExM work with @gautamdey.bsky.social & @centriolelab.bsky.social will still be printed out in the lab. Read here: www.cell.com/cell/fulltex...

Some light reading for the holidays :). Let us know what you think.

New preprint🚨 Imagine (re)designing a protein via inverse folding. AF2 predicts the designed sequence to a structure with pLDDT 94 & you get 1.8 Å RMSD to the input. Perfect design? What if I told u that the structure has 4 solvent-exposed Trp and 3 Pro where a Gly should be? Why to be wary🧵👇

#EvoChromo ciliate kinetochores @maxraas.bsky.social @kopslab.bsky.social . Previous work w\ @jvhooff.bsky.social : tinyurl.com/y5h4ehnt showed a lack of Tetrahymena kinetochore complexity. Replacement, simplification or missed homologies? All of the above? - check out our pre-print tiny.cc/hp8w001

Our story on the kinetochore composition of the ciliate Tetrahymena thermophila is out now on bioRxiv! We find surprisingly many orthologs of conventional kinetochore components, but also components that have very different evolutionary origins. A 🧵 (1/11) Check it out here: tinyurl.com/4ectm9x4

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

Our new preprint describes Plasmodium NEK4 as a key regulator coupling meiotic initiation and morphogenesis—a critical step for malaria transmission. This involves MTOC-driven nuclear movement strikingly analogous to "horsetail" movement in fission yeast. www.biorxiv.org/content/10.1...

New work on ARK1 (AURKB?) in Plasmodium (malaria parasite) with @ritatewari.bsky.social and Pushkar Sharma. CPC in Plasmodium is (ofcourse..) different compared to conventional models: two INCENPs, no borealin/survivin - mainly at spindle microtubules/MTOCs. Special thanks to @ryanase.bsky.social!

Pleased to share our new preprint: "Plasmodium ARK1 regulates spindle formation during atypical mitosis and forms a divergent chromosomal passenger complex". Many thanks to our collaborators. @ritatewari.bsky.social @eelcotromer.bsky.social @davidguttery.bsky.social www.biorxiv.org/content/10.1...

Happy to share the first story from my postdoc in @schnittger-lab.bsky.social We studied TITAN9, a Csm1-like protein in Arabidopsis. Even though I now work with soil, chromosome segregation and meiosis still have a special place in my heart. #meiosis4eva #meiosis #chromosomesegregation

So excited to share this preprint from the Rosin lab in collaboration with the Hawley lab and @eelcotromer.bsky.social on moth spermatogenesis! We investigate the meiotic errors that occur during the formation of apyrene sperm (that have no DNA) in silkworms! www.biorxiv.org/content/10.1...

We are growing! A new @zeiss-microscopy.bsky.social widefield tailored for ExM- supported by @moorefound.bsky.social is settling! Another one is on its way at @gautamdey.bsky.social Lab ! These two will become the powerhorses for high-througput imaging of the ExM Atlas of #Microbial Eukaryote !

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!

It’s out! The evolutionary origins of yeast point centromeres uncovered! “Ancient co-option of LTR retrotransposons as yeast centromeres” www.biorxiv.org/content/10.1...

OMG IT IS OUT EUKARYOTIC HOPANOIDS DESERVE ALL CAPS www.nature.com/articles/s41...

I am happy to share a preprint on the marine plankton project I started one year ago (thanks to Julius and Drahomira's help) www.biorxiv.org/content/10.1...

Asgardarchaea & Alphaproteobacteria: key players for the assembly eukaryotic central carbon metabolism! Our new study reveals their gene contributions to glycolysis & TCA cycle, supporting synthrophic scenarios of eukaryogenesis. rdcu.be/eb0aK

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...

Have questions about #bioinformatics, #genomics, #evolution or stuck on a project? 🧬💻 I want to help! Happy to discuss data, figures, writing, academia/industry or chatting just for kicks—no strings attached Drop questions below, DM, or schedule a meeting Science together is better than alone 🙌

A new preprint from our group in collaboration with @jvhooff.bsky.social and @eelcotromer.bsky.social. We discovered that trypanosomes have (a zombie of) Bub1-Bub3 despite the fact that tryps do not have a canonical spindle checkpoint! This is a team work involving Dan, WillC, Midori and Patryk
