Delicious!

Kinda. But with less caulo.

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!

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

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 👏

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.

Universal rules govern plasmid copy number - Nature Communications Plasmids exhibit a broad range of sizes and copies per cell, and these two parameters appear to be negatively correlated. Here, Ramiro-Martínez et al. analyse the copy number of thousands of diverse b...

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 👇

I guess I am hitting a nerve, because they just put me on admin leave. TikTok video by Jenna

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.

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

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

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

Not enough labs study cyanobacteria.

Great to see you joining in!

We were getting lonely!

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.

He seems like a really nice guy, I hope his team comes in 2nd place.

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...

Paralogs with distinct phase behaviors broaden the in vivo stress response range of condensates Paralogs are widespread, but their physiological roles are often masked by redundancy. H-NS, a nucleoid-associated protein in Gram-negative bacteria, typically coexists with paralogs such as StpA, who...

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.

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.
