I am beyond excited to announce that the Bisson Lab has a new home!!! Starting January 2026, I will join the Biology Department at Indiana University Bloomington as Associate Professor with tenure. I am actively recruiting scientists across all levels. More in our website: bissonlab.com/join [1/4]

Can’t wait!! My bacterial cell bio friends, you’re gonna want to go to this GRC and GRS.

Just got word that we are a go for the Bacterial Cell Biology and Development GRS and GRC at Southern New Hampshire University! GRS will be on June 5-6, 2027 GRC will be from June 6-11, 2027 Block off your calendars Prokaryotic Cell Biologists! More details to come! Please repost!

NSF - Forced reorg - POs down ~ 40% (DRP, most rotators not renewed, retirements) - Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …) I personally love the boxes they gave us for packing. “Details matter” 🙃

📄 Delighted to share that the preprint of my main PhD work is out now! 👏 A huge thank you to everyone involved, @tommclean.bsky.social, Govind Chandra, Ngat Tran (both not on BlueSky) and especially my PhD supervisor @tunglejic.bsky.social 👏 🧵 below! www.biorxiv.org/content/10.6...

Fabulous summer research opportunity for undergraduate students.

Equipositioning of Chromosomes in the Polyploid Archaeon Haloferax volcanii by HpaAB https://www.biorxiv.org/content/10.1101/2025.11.19.689047v1

I’m excited to share my recent postdoc work. Here, we interrogate how different phage infection outcomes (productive vs. restrictive) affect the expression of phage defense systems. We find that a restricted infection not only inhibits the phage but also induces increased immune protein abundance.

Curious about plasmid biology? Our latest paper is out now in Nature Communications! 🚨 doi.org/10.1038/s414... We analyzed thousands of diverse bacterial plasmids to shed light for the first time on a key aspect of plasmid biology: plasmid copy number. 1/7 👇

Trump’s HHS put me on “non-disciplinary” admin leave today. This was retaliation for speaking up. Moves like this are designed to silence us. Let’s not let. www.tiktok.com/t/ZP8Dteoop/

NSF is open again! A few comments: *Please be patient. During a shutdown NSF employees cannot open computers or respond to emails. *Merit review will continue. However panels won’t resume until after Dec 8th. *POs remain excited and committed to advancing science and the scientific workforce.

📢 Postdoc position: Biochemistry & Bacterial cell biology in our group at Marburg University, Germany, funded by the ERC Advanced Grant "C-SWITCH" 🔗More information at shorturl.at/OlvlL 📅Deadline: Nov 30, 2025 Please repost. #Postdoc

PSA for people with NIH grant periods starting January 1st (including most NIGMS MIRAs): your RPPR is due Saturday, but they haven’t sent out the usual automated reminders, presumably due to the shutdown

Canadian Premier Soccer final is the most bad ass soccer game I've seen.

Friday means a new #MattersMicrobial podcast. This week, Dr. Hannah Ledvina joins the #QualityQuorum to chat about how bacteria can shield themselves against Bdellovibrio attack! Please spread the #GoodMicrobialWord. @univpugetsound @ASMicrobiology @microbe.tv youtu.be/n31kkw576GE?...

One of the most useful resources for anyone who uses fluorescence methods.

Right now this is my favorite @inaturalist.bsky.social observation www.inaturalist.org/observations...

I had the most awesome time recording next week's #MattersMicrobial podcast session with Dr. Hannah Ledvina of the University of Michigan. Her work on the "shield" that E. coli can make against Bdellovibrio attack was amazing. Plus, we share many common enthusiasms. It was a proper nerdfest.

LA Dodger’s Freddie Freedom speaks about his Canadian Mom. He seems like a really nice guy, I hope his team comes in 2nd place. #Canada #TorontoBlueJays #LADodgers #WorldSeries

Complete nonsense. My advice to post-graduate researchers is to always preprint their work, as it will improve their visibility while the manuscript is going through a (frequently very long) peer review process.

Always read @jtemple.bsky.social, especially when he quotes me. 😆 R&D on CO₂ removal (CDR) should be funded and led by governments, like the Manhattan Project minus the nuclear bomb. That way we can figure out what works and what doesn't technologically, environmentally, socially, etc.

Thrilled to share our multidisiplinary work on how genome-wide DNA bridging by H-NS reshapes the stationary phase bacterial nucleoid and affects the transcriptional landscape. With Xindan Wang and @meyerroc.bsky.social www.biorxiv.org/content/10.1...

Bacteria use paralog teamwork to survive stress. H-NS forms fluid condensates; its partner StpA forms rigid fibrils. Together, they balance flexibility & stability to keep genes properly regulated under pressure. #PhaseSeparation #Bacteria www.biorxiv.org/content/10.1...

Hello! The Jacobs-Wagner lab is finally on Bluesky. We’re excited to celebrate science (and scientists!), share our research, and interact with the community. We look forward to connecting with friends and colleagues across the world.

We’re excited to announce the incredible speaker line-up for the Prokaryotic Cell Biology Conference! Join the leading researchers as they explore the latest advances in Nanoimaging, Cell Growth and Cellular Structures. Join our speakers & register today! ➡️https://bit.ly/47rtkbw #ProkaryoticCellBio

Our paper on chromosome segregation in the archaeon Sulfolobus Acidocaldarius has been published in PNAS! This has been a great collaboration with @joeparham19.bsky.social and the rest of @buzzbaum.bsky.social's team. Stay tuned for more to come!😉 @istaresearch.bsky.social doi.org/10.1073/pnas...

Hey Americans! How’s that baseball series going?

I have been trying to get this published as an op-ed, but I am going to post it here since I think it is timely in light of the "consent" extortion events. Deafening Quiet from the Scientific Establishment jeremymberg.github.io/jeremyberg.g... 1/14

Interested in a tenure track position teaching and doing research with undergrads at a PUI? We are looking for a broadly-defined microbiologist who can teach Med Micro and Immunology. Apply at universityofscrantonjobs.com/postings/8308. Pls share widely to feeds (& on twitter if you still tweet)! 🦠

New PrePrint from the Vecchiarelli and Mosalaganti (@shyamalm.bsky.social) labs! 🧵 Collaboration with the Giessen and Pi labs Congratulations to co-first authors Y Hoang (@hoanghamyy.bsky.social) and Pankaj Jadhav! www.biorxiv.org/content/10.1...

Independent research fellowships leading to tenured positions at the John Innes Centre. Repost = nice. Thank you very much!!!

This is why we fund scientists to study things like oyster slobber even if you don’t think it sounds important

Invited to give a talk by graduate students-who DRIVE research nationwide-is easily one of the greatest honors for a PI. It’s even better when one of your former mentees is the host! Thank you Tanner and @harvard.edu Micro for being a bright light in these dark times. 🙏 Science will prevail 💪

We kicked off the new school year with the launch of the BioFoundry for Extreme and Exceptional Fungi, Archaea and Bacteria (ExFAB). The new facility will allow researchers to make novel discoveries using previously unstudied microbes that could generate advances in biotechnology & biomanufacturing.

THE Erwin Frey, talking about self-organization in biological systems. Title of the seminar serie suggests it might be intended for physicists.

thank you to all the NIH staff who stand by their duty and put in heroic efforts to get it done. I'll never forget it and will be eternally grateful.

We've already got hundreds of students and mentors here, sharing how the sudden policy change has derailed plans. We're looking at formally "delivering" results to NSF leadership tomorrow, please do keep sharing and spreading the word: laurenkuehne.github.io/grfpChanges/
