Here is the "effective payline" for each institute, estimated (by Claude) as the percentile where one can expect 80% probability of funding from a logistic regression fit. The effective payline has gone from a historic ~12% to 6% in 2025.
New in JB: Schmidt, Thormann study the polar landmark protein FimV of P. putida & find it binds peptidoglycan, swimming & localization of the Che system, participating in different functions than homologs in other microbes.

New In JB: Phale, Kasarlawar et al. review the unusual traits of Pseudomonas bharatica CSV86T, an organism that they offer as useful for both bioremediation and up-cycling aromatic compounds.

Our story on the evolution of colistin resistance is just out on @plosbiology.org (journals.plos.org/plosbiology/... Evolution doesnβt happen in isolation. We show that competing fungi can rewire the evolutionary trajectory of colistin resistance in P. aeruginosa. Great teamwork with the Ernst lab
New in JB: Hartzler, Metskas et al. review recent information about Ξ±-carboxysome structure, mechanism, and assembly through the lens of cryo EM and tomography. A really exciting topic - one of my favorite areas to include in my grad course!

Our newest paper by Sarvesh Surve, a PhD student in the lab, explores the culturome of the regions of the gut for persons with CF. We see clear differences from healthy controls, esp. in the mucosal samples.

Flyer for ASM DC Branch Meeting April 10th at Howard University
Attn DC area microbiologists, please join us for @asmdcbranch.bsky.social Spring Meeting on Fri, Apr 10th from 10-4 at Howard University. Keynote by Dr. Kumaran Ramamurthi. If interested in giving a short or lightning talk, submit abstracts by Mar 25: www.washingtondcasm.org/2026-spring-...
Given that clonal biofilms of single bacterial species rapidly diversify into niche specialists, how do biofilms of multiple species evolve?

JB Editor's Choice: As part of our History of Microbial Model Systems series, Snow, Hatzios & Salama discuss the first bacteria designated a class I carcinogen, Helicobacter pylori.

JB Editor's Pick: Iglesias, Mongiardini et al. show that loss of the Tad pili of B. diazoefficiens results in enhanced biofilm formation - they propose a regulatory role, perhaps via cdG, for Tad impacting biofilms in this bug.

I had the fun opportunity to write a Commentary for a JB paper by Bhattarai, Harshey et al. describing their Texas Two-Step model of cdG-mediated motility control.

Scientists have seen Asgard archaea crawling for the first time. When it comes to the origin of eukaryotes, this is like seeing a feathered dinosaur in the wild. (Video courtesy of Philipp Ralder)
New in JB: Askar, Chu et al. review the function of the aminopeptidase M17, a metallopeptidases, in bacteria and its potential role as a drug target. This review also nicely covers the history of research of this group of enzymes.

𧡠New preprint! Our 4-lab team evolved Streptococcus pneumoniae in antibiotic-treated mice of varying immune states and discovered something surprising: bacteria rarely evolved resistance. Instead, they found a different way to survive β by rewiring RNA turnover.

Sad to hear about Dr. Harpp's passing. He was a great scientific communicator and I really enjoyed his World of Chemistry lectures as an undergrad at @mcgill.ca. Rest in peace Dr. Harpp.

We're finishing up our 30th M2P2 retreat, with Salvador Almagro-Moreno - our keynote for the Ron Taylor Keynote lecture, a poster session, two career development workshops and ~120 attendees from across northern New England. We also had some open time to network - plus skating & skiing. m2p2.org
Excited for this new preprint from former postdoc @caitlinkowa.bsky.social identifying unexpected functions for the bacterial stringent response in antimicrobial fatty acid susceptibility in S. aureus #microsky
Can someone pinpoint if there is a Pseudomonas putida (e.g. KT2442) database where we can find out which lab has certain deletion mutants and/or report strains?
Coming from the B.subtilis field with #SubtiWiki containing all these info, it is difficult to find all available mutants in the papers

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects.
