So it turns out that chromatin in archaea takes the hellish form of a Lovecraftian tube worm 🪱🔥
Love it! Thanks for the nightmare-fuel! 😱
#ArchaeaSky @dodonova-sveta.bsky.social 🧪
@embl.org at its best: collaborative, open, transformative, and just the right amount of crazy. Dreaming of mechanistic cell biology *in the natural environment*? Dream no more, rent the AML.

So one day, I walk into our lab and @computingcaitie.bsky.social & @abimoye.bsky.social are carying eyeballs around everywhere 👀. Thanks for the eye-opening collaboration! (literally, ha!) 🧪
Great to see our paper on light-intensity dependent swimming patterns in #Chlamydomonas out now in Phys Rev Lett. as an Editors' suggestion! With a nice commentary by @philipcball.bsky.social.
Chlamy actively modulate the beat planes of their #cilia!

Haha, I am notorious for my strong feelings on segmentation colors 🌈🎨 🧪
But did we pick the exact right shade of pink? Maybe we should try five more? 💕
Pretty figure incoming @lowlab.bsky.social 🤗
Histones in archaea, you say? Check out this new paper from @dodonova-sveta.bsky.social @embl.org 😁 🧪

It's very cool! I already teach this awesome study from @florianwollweber.bsky.social & @pilhoferlab.bsky.social in my first-year cell bio class at the @biozentrum.unibas.ch

Very cool environmental #CryoET. This is an exciting frontier for #TeamTomo 🧪 🌍
I agree. Grandstanding without putting more money in the pot 💰. Funding is tighter than ever this year, even in Switzerland🇨🇭 …the @snsf.ch is taking a big hit 😣
Thanks Khaled 🌱😊
Chloroplast-encoded small subunit extensions reshape the Chlamydomonas chlororibosome www.biorxiv.org/content/10.64898/2026.02.07.704542v1 #cryoEM
This is absolutely gorgeous work from @helenfoster.bsky.social, @margotriggi.bsky.social, @gaiapigino.bsky.social and colleagues 🤩
#Chlamy cilia never cease to amaze!
At long last, the Chlamy chloroplast ribosome hat 🎩 (now renamed the arm 💪) is here to say hello👋! We first spotted this extended structure in green algae a decade ago, and @florentwaltz.bsky.social did beautiful work bringing it into focus! #CryoEM ❄️ #TeamTomo 🔬 #PlantScience 🌾 #ProtistsOnSky 🧪
For #ECR’s:

Thanks Johann! Big congrats on your beautiful work as well. Really jaw-dropping #CryoET!! 🤩 I agree there are some cool parallels between the systems 🤓 🧪
Big thanks to @nanoscience.ch 🇨🇭 for funding our part of this project, enabling @phaips.vd.st to work with us and @mariahondele.bsky.social at the @biozentrum.unibas.ch @unibas.ch. And big high-five🙌 to our York🇬🇧 collaborators, led by Gaurav, @james-r-barrett.bsky.social & @mackinderlab.bsky.social
Here it is @jimhurley.bsky.social. Happy to have some feedback! 😁

Our new paper, out today! We resurrected ancient nitrogenases first used by life on Earth 3 billion years ago. We combined synthetic biology and geology & validated their chemical #biosignature in rocks that helps reveal ancient life on Earth!(and beyond!)

Super interesting! Congrats, and thanks for sharing :)
Check this new study on carbon concentration mechanisms!
See how the pyrenoid changes by modifying Rubisco linkers in our favorite alga, Chlamy 💚!
My desk mate @phaips.vd.st spent a lot of time collecting & carefully analyzing these beautiful tomograms 🔬.
Congrats to all the authors!
That is a really beautiful poster!🤩 🧪

You like #LLPS? #TeamTomo? #Rubisco? Check out our latest preprint!
What a great collaboration this has been!
Check out this cool thread on the latest preprint by Gaurav Kumar, @james-r-barrett.bsky.social, @phaips.vd.st from our lab and colleagues, dissecting the physics of Rubisco condensates!
You're in for some stunning #cryoET of the pyrenoid - in Chlamy, of course 😉
Congrats to all involved!
Excited to share this detailed biophysical study of #PhaseSeparation in the Pyrenoid, an algal microcompartment that fixes a third of the Earth's #CO2 🌏. We combine methods across scales, in vitro 🧪 and in vivo 🦠
Thanks for the very fun collaboration! 🤗

How do diatom cells maintain a constant supply of carbon for photosynthesis? Our microelectrode measurements of the phycosphere around individual diatom cells show that diatoms can rapidly switch between distinct carbon acquisition pathways. @thembauk.bsky.social www.science.org/doi/10.1126/...
#TeamTomo visualizes amazing (green 💚♻️) proteasome crystals in yeast. This project was a long time coming -- I remember talking to Cordula about it back when I was a postdoc in Martinsried. Some really cool and surprising findings here. Nice to see it out, and congrats to all the authors! 🧪 🔬
SHAPES being the key word, amirite @nanigrotjahn.bsky.social

Should be an interesting #TeamTomo talk. Check it out! 🧪 🔬
Fair enough.... but actually, archaea are the master extremophiles, and many bacteria have more complex internal architecture than we used to think. It was their equal collaboration and subsequent specialization that made Eukaryotes what they are.
Well, archaea didn't do it alone -- it was an equal partnership with alpha-proteobacteria. Hard to expand into a newly oxic world (2 BYA) without a mitochondrion that can use oxygen as a terminal electron acceptor. 🧪
Go #TeamTomo! 🧪 @wilflinglab.bsky.social & @nanigrotjahn.bsky.social are on a roll! Beautiful in-cell visualization of lysosome rupture 🎈💥
