I am so proud of this work spearheaded by @lilymcknight.bsky.social! In this ~4-year effort, we reveal that the presence of GpsB is crucial for cell wall stress response and antibiotic resistance (via Stk/PknB and VraSR) in S. aureus. See the thread below for more info! #MicroSky #AMR #ProudPI

FACULTY POSITION: We are seeking an Assistant Professor to join our growing and vibrant Department of Microbiology at Cornell! FOCUS: Using bacteria to address 21st century challenges. (part of a cohort hire in SynBio). *please repost* academicjobsonline.org/ajo/jobs/33098 #MicroSky

GpsB is the hardest working protein in Firmicutes (it's a hub that modulates ~10 different cell division & cell wall synthesis proteins), but how can one protein manage all this? Apparently, the answer is phosphorylation. Great new paper by @lilymcknight.bsky.social and @eswaralab.bsky.social

Our Biochem Dept is hiring! Come join us! Please Repost! 👍

Looking for a faculty position combining research in fundamental cell and molecular biology with therapeutic discovery? Join our amazing faculty at the @weillinstitute.bsky.social at Cornell University in Ithaca, New York. academicjobsonline.org/ajo/jobs/32657 Apply by Nov. 15! Please share!

the "Mg²⁺ problem" has been known for a long time. For example, in the standard "rich medium" LB (see👇). now we get to know more about the reasons! #MicroSky

Applications are now being accepted for the 2027 Bacterial Cell Biology & Development GRC, June 6–11! GRS will be on June 5-6, 2027 We’ll likely be oversubscribed, so please apply early!

Folks have known for years that adding magnesium to media rescues the lethality of deleting many 'essential' genes, but why? @eswaralab.bsky.social and @subtisilly.bsky.social say that free iron builds up in these mutants. Mg2+ mitigates this by redirecting metabolism towards limiting ROS production

UNC Greensboro Department of Biology is hiring for three positions this year including one in microbiology! spartantalent.uncg.edu/postings/35918

#MicroSky act fast! Sept 4th is the registration deadline for Midwest Microbial Pathogenesis Conference (MMPC) that will be held in Minneapolis from Sept 25-27 #mmpc2026

Excited to share my latest work in the @ramamurthilab.bsky.social, now in @cp-cellreports.bsky.social! We show that division geometry organizes surface adhesins in S. aureus and enables the formation of abscess communities that protect bacteria from immune cells. www.cell.com/cell-reports...

Thrilled to share this insightful work of Asher King @subtisilly.bsky.social and Pilar Horigian @pilarhorigian.bsky.social! #ProudPI #MicroSky #AMR #SubtiWiki In this work, we reveal the *magic* behind the protective effects of magnesium in Bacillus subtilis. Read Asher's 🧵 below for more details.

Ribosomal RNAs are modified, but why? Zac Park examined a methylated residue on 16S rRNA in #Bacillus subtilis. He says 1) methylation by MraW permits robust translation, & 2) select transcripts evolved stem loops that fine tune the amount of protein produced www.sciencedirect.com/science/arti...

@felixrl.bsky.social told us previously *how* #Staph aureus does orthogonal cell division. In his latest paper he tells us *why*: to arrange cell surface proteins required to form staphylococcal abscess colonies. (Videos S1-S2 are amazing!). 🤯 www.cell.com/cell-reports...

Huge faculty recruitment effort at the University of Chicago -- a division-wide, open-rank search looking to hire about 20 faculty across 5 research areas in biology. Come be our colleague! Full announcement: uchicago.app.box.com/s/ckih9zv3rj...

Come be our colleague. I have been in this Division for 27 years (4 as a postdoc and 23 as a PI). It is an amazing place to work, collaborate, and be inspired. If you are applying to be an Assistant or Associate Professor this Fall, don't miss this deadline.

Biofilm formation in #Bacillus subtilis is thought to precede sporulation, but T. Updegrove says that a subpopulation of sporulating cells triggers other cells to become biofilm formers via an intracellular metabolite (glycerol) repurposed as a signaling molecule (!) www.science.org/doi/10.1126/...

Session proposals are open - hope to see you in Chicago!

Devastated to report that Brandon Jutras passed away a day or two ago. Brandon earned his PhD with me. He went on to be an Associate Professor at Northwestern University School of Medicine and a super star in Lyme research. A loving husband and father, a sincere friend, and a brilliant scientist 💔

Pls share: U of Washington has an opening for a tenure-track faculty position at the rank of Assistant Professor. This position is expected to specialize in molecular virology or bacteriology. Here is a link: microbiology.washington.edu/index.php/ne...

New pre-print from the lab, about impact of cell wall antibiotics on PG elongation machineries. Any comments and (constructive) criticism are welcome!

Open postdoc position in my lab on HGT and interbacterial competition. We seek candidates with a PhD in microbiology (or related fields)+ strong 1st-author publications. Curious, highly motivated, and dedicated team players ready to contribute fully are encouraged to apply. Details: tiny.cc/cz01101

📢 We're hiring! The Department of Microbiology & Cell Biology at Montana State University is hiring an Assistant Professor of Microbiology. We welcome applicants working in microbial pathogenesis, immunology, genetics, microbial evolution, and related areas. Apply: jobs.montana.edu/postings/52009

Another chapter of my thesis is out! We asked whether we could pair proteome-wide AlphaFold screening with Tn-seq to identify biologically relevant protein-protein interactions. We identify ClcR (formerly YerH) as a component of the Rod complex in Gram-positive bacteria. www.pnas.org/doi/10.1073/...

What would happen if Darwin, Russell Wallace and Koch walked into a bar? We present our new way to study mycobacteria, employing a macroevolution framework (species not strains). Possibilities are endless!! Thanks to Fernanda Subtil for pushing this. elifesciences.org/articles/101...

Today marks 30 years since we identified the apicoplast, a relict plastid in human and animal parasites (PMID 8632819). Apicoplasts are the target of the widely used antimalarial prophylactic doxycycline, which has saved many thousands of malaria infections.

@agnese75.bsky.social's work is out. She shows that under iron starvation M. tuberculosis splits flux through the Krebs cycle and secretes metabolites, akin of fermentation. Why is this important? Metabolic flexibility is what makes it so hard to kill in vivo. elifesciences.org/reviewed-pre...

Congratulations, Maria and team! 🤩 👏🏾 When we wrap up all the dissertation projects started by @drmariawhite.bsky.social, Dr. White will easily have another 4-5 publications! 💪👩‍🔬

Bacterial transmembrane proteins usually localize inside the cell by "finding" a pre-localized protein, but how did the 1st protein get there? @vanipande.bsky.social found a protein in #B.subtilis that localizes by recognizing a *lipid* localization cue. #Microsky www.biorxiv.org/content/10.6...

This news is heartbreaking! I remember Allie's excellent talks at Phages (Madison, WI) and at ASM Microbe last year. We spoke just few months ago regarding collaboration. What an immense loss to the scientific community! 🇺🇸 🇫🇷 🇯🇲 Deepest condolences! 🕊 #MicroSky medschool.ucsf.edu/news/remembe...

Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. https://scim.ag/4nTQ3nq

New preprint! Cell division has to happen at the right place but how Archaea pick that place is unknown. We now identified a three-protein system, Dip, that positions the divisome at midcell in H. volcanii and is broadly conserved across Archaea. A thread 🧵 www.biorxiv.org/content/10.6...

We are hiring! Focus is on colleagues interested in protein homeostasis and human disease. Priority reviewing starts mid-June and will continue on a rolling basis. Here is the ad, hit me up if you have questions! careers.umass.edu/jobs/assista...
