Welcome to our first postdoc in the ACO Lab, Andy Garcia! 🎉

Supporting each other as #newPI is very important, and @antonioserapio.bsky.social is great at it

🚨 🚨 🗓️ The deadline to submit your abstract for the #ASCB2025 meeting in Philadelphia is this Wednesday, September 3!! Dyche Mullins and I are hosting the session “Cell Biology at the Extremes”. Thermophiles, psychrophiles, tardigrades, giant bacteria… now is your time to shine!! 🚨

New hot fluorescent tag dropped!

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social! www.biorxiv.org/content/10.1... #Chromatin #Asgard #Archaea #cryoEM

The archaeal S-layer is not only pretty, it also carries crucial cellular functions, and the list keeps growing! @sshamphavi.bsky.social @marleenvw.bsky.social @archaellum.bsky.social and I wrote a little sheath sheet (+10 pts if you got the pun) 📖 Curr Opin Cell Biol 🔗 doi.org/10.1016/j.ce...

What a year for the cell biology of archaeal chromosome segregation! 🧬 @joeparham19.bsky.social and @buzzbaum.bsky.social now add pieces to the SegAB puzzle by connecting it with cell division

To explore how ring assembly and DNA segregation might be coupled, we turned our attention to the ParA homologue, SegA, and its partner SegB, using antibodies kindly gifted by @acharlesorszag.bsky.social (see www.biorxiv.org/content/10.1...)

In just 2 days on WEDNESDAY, May 14th at 10 AM EST / 4 PM CET, @fabaiwu.bsky.social will kick off our last spring APH session by telling us about his new research investigating the evolution of DNA replication machineries from Archaea to Eukaryotes!!! Visit our website (link in bio) for more info!

Think you're under pressure? Marion Illartin will close out our last APH session of the semester by telling us about her multidisciplinary approach to characterize how pressure regulates the SurR transcription factor in everyone's favorite barophile, Thermococcus barophilus!! Zoom in on May 14th!

Don’t miss it!! Last APH of the season 🫶🏼

The unique #CellEnvelope of #corynebacteria: @tbharat-lab.bsky.social &co map the C. glutamicum cell surface, revealing a patchy S-layer & specific assembly of the PS2 protein, thereby informing our understanding of cell envelopes that contain #MycolicAcids @plosbiology.org 🧪 plos.io/3Y6JNgw

Excited to announce the Molecular Biology of Archaea (MBoA) 2026! Join us in Cambridge, UK, from 6–10 July 2026 for the only international meeting dedicated to Archaea.

Coolest office poster, the Beaud - Gribaldo ToL 😎 Thank you @sgribaldo.bsky.social and @babebe.bsky.social 🫶🏼

Preprint alert! I’m publishing my last paper from my postdoc work on archaeal cell biology, with @mullinslab.bsky.social, @archaellum.bsky.social, @samjlord.bsky.social, @marleenvw.bsky.social, @arghya93.bsky.social, and more great folks (thread below with more details)

Never too late to repost a great paper ✨ Huge congrats to @archaeon-alex.bsky.social and the amazing Theopi Rados (and all the authors ofc) 🫶🏼

🚨 Tune in this Wednesday for more exciting archaea science!

Nearly 40% of transgender and gender-nonconforming biologists report experiencing hostile behavior at work, according to the largest survey of LGBTQ+ biologists, created by ASCB's LGBTQ+ Committee. www.nature.com/articles/d41...

Second up on Wednesday, March 12th, we'll have Priyanka Chatterjee talk to us about her intriguing research into quorum sensing in the salty Haloferax volcanii, identifying many key players in this cellular communication response in archaea! Check your email for the Zoom link!

Archaea Alert! We're just one day away from our next APH session! First up, @cjhines.bsky.social will tell us about his exciting work to uncover the elusive last step of coenzyme M biosynthesis and to demonstrate its effectiveness as an antioxidant!! Make sure to tune in on March 12th, 11AM EST!!

🚨 This Wednesday!!

Welcome to the Bluesky account for Stand Up for Science 2025! Keep an eye on this space for updates, event information, and ways to get involved. We can't wait to see everyone #standupforscience2025 on March 7th, both in DC and locations nationwide! #scienceforall #sciencenotsilence

Micron-sized Valentine’s Day card to y’all 🫶🏼

Extremely happy to see our work finally out!🎉 Great collaboration between @rouxlab.bsky.social @buzzbaum.bsky.social labs and a real pleasure to work and share co-first authorship with incredible scientists and friends @diorgeps.bsky.social @sami-c.bsky.social. Big thanks to the rest of the authors!

Mark your calendars! Archaea power hour is back!

Scientific Director, Cal-Cryo. We are looking for an outstanding microscopist to run our cryo-EM facility (two Krioses and an Arctica), increase training, engagement, and collaboration on campus, expand our user base, and join our community of cutting edge cryo-EM researchers. tinyurl.com/ykasna3p

Archaea Power Hour 2025 resolution: switch to BlueSky. Give us a follow!

Such a beautiful paper!!

Dynamic duo at the cell's edge: Caveolae and the actin cytoskeleton work together to sense and respond to mechanical stress. Caveolae buffer tension, while actin provides structure and force. Ultimate biomechanics team. #CellBiology #Mechanotransduction

Speakers, try adjusting gamma on your images (e.g. 0.45) on your slides. Especially for images that are still hard to see after optimizing contrast. #CellBio2024

TLDR: reminder @mullinslab.bsky.social and I are hosting the “extreme cell biology” session at @ascbiology.bsky.social next Monday!

Archaea Power Hour doesn’t have a BlueSky yet (soon!) but here’s the lineup for tomorrow’s APH virtual conference!

Clathrin-coated pits working overtime in your heart this weekend🔬 #ClathrinLife #WeekendScience"

Save the date 📆 Dyche Mullins and I are hosting the “Cell Biology at the Extremes” session at the #CellBio24 meeting on Monday, Dec 16, 5:00 PM. @ascbiology.bsky.social You’ll learn about the latest cool ❄️ hot 🔥 and ultrafast 💨 cell biology. Kindly supported by @focalplane.bsky.social

Excited to share our new study with the Müller and @SchullerJm labs, online @nature: https://www.nature.com/articles/s41586-022-04971-z This is T. kivui, an anaerobic bacterium. It uses hydrogen energy to store #CO2. How does it do it? #CryoET revealed membrane-anchored bundles of...

Have you ever heard about sheaths? Happy to share our last paper with @sgribaldo.bsky.social and Guillaume Borrel @pasteur.fr where we investigated their distribution and evolution! doi.org/10.1093/isme... Below a thread of our major findings:

After years of work, our podcast series on #archaea is finally releasing episodes! Listen to the first two and subscribe to get more every two weeks!

My turn to create a starter pack for scientists using live imaging in their research! Of course, I’ve likely missed many—please let me know who else I should include. Thanks! go.bsky.app/KYYr7xc #liveimaging #livevellimaging #microscopy

Bonjour à vous, aussi nombreux et nombreuses que vous êtes ! On a commencé un kit de démarrage pour que vous puissiez suivre les personnes qui parlent de sciences en tout genre. On l'implémentera au fur et à mesure des arrivées ! Et c'est par là que ça se passe 👉 go.bsky.app/CFvzzJP

Reminder to use SuperPlots in your papers if you still aren’t 👇🏻

Buh-bye little evil birdie
