- Congratulations to @emmynguyen.bsky.social and our wonderful collaborators. Here we uncover and characterize a periplasm protein that modulates broad physiological changes to V. cholerae by controlling a two component system!
- Thrilled to share that my first-author paper is now published in Nature Communications! 🎉 Huge thanks to my PI, Dr. Drew Bridges (@bridgesbio.bsky.social), my collaborators, and all the incredible lab members for their support throughout this project www.nature.com/articles/s41...

- Reposted by Drew BridgesI'm delighted to share a useful FREE web-based app portal of powerful bioinformatics tools for microbial genomes and shotgun microbiome sequences! It's called Micromics and is built by Middle Author Bioinformatics, led by co-founder @ironark.bsky.social omix.midauthorbio.com

- Excited to host a session at @asm.org #Microbe2025 in LA. Our session is entitled, "Acting As a Unit: Regulation of Microbial Collective Behaviors From Molecules to Populations." Please join us and submit an abstract! www.abstractsonline.com/pp8/#!/20974... #Microsky
- Excited to share our latest, "Biofilm dispersal patterns revealed using far-red fluorogenic probes." @plos.bsky.social We developed a cell-labeling strategy using far-red dyes to image dense microbial communities (where fluorescent proteins often do not work well) journals.plos.org/plosbiology/...
- Using this approach, we characterize biofilm dispersal in V. cholerae. We find that dispersal initiates at biofilm periphery and ~25% of cells never disperse. We define novel micro-scale patterns during dispersal, including biofilm compression and regional heterogeneity in cell motions (see movie).
- We anticipate that the FAP-fluorogen labeling approaches described here will enable research in diverse areas of microbiology. O2 independence combined with far-red spectral properties! Could be used to tag proteins, to label multiple organisms, or to monitor gene expression. #microsky #biofilm

- Reposted by Drew BridgesHas anyone had the time to setup a starter pack for the brave 🙌🏻 early adopter scientific journals that have migrated to BlueSky? 🧪🦠🧬💉🩻🔬🧫
- Reposted by Drew Bridges...and tag your own posts with #MicroSky if appropriate. it helps (=be your own algorithm 😌)
- Has anyone made a microbiology or bacteriology starter pack??
- Reposted by Drew BridgesAnother starter pack of fine fine folks - New PIs! We're all figuring it out together! Please do (self-)nominate go.bsky.app/KJXNgfZat://did:plc:o7tynxmyxsuhoeknkm7r2dul/app.bsky.graph.starterpack/3lagwihfkla2o
- Reposted by Drew BridgesThrilled to have presented my research in the lab of @bridgesbio.bsky.social at three conferences this year: Bacteria and Phages, ABASM, and Rust Belt Microbiome. Grateful for the chance to share my work and connect with inspiring scientists. Can't wait to see what future conferences bring!

- We determine that additional pathogenic organisms also exhibit multicellular community formation in response to lysis. Given the pervasiveness of lysis in the environment, we propose that lysis sensing is a threat-agnostic mechanism by which bacteria can gauge endangerment. (4/4)
- We identify the cell lysis signal as an abundant cytoplasmic polyamine, norspermidine, which is detected by an inner-membrane receptor, MbaA, that in turn drives biofilm formation. (3/4)
- We find that the mechanism underlying this observation is a process we refer to as "lysis sensing"...whereby surviving cells sense a signal released by the death of their kin. (2/4)
- Our first paper from the lab! We find that upon exposure to lytic phages, the pathogen V. cholerae rapidly lyses, but then recovers, with surviving cells exhibiting robust biofilm formation. www.nature.com/articles/s41... (1/4)

- Had a blast writing a commentary #msphere on “Biogeography of a human oral microbiome at the micron scale” by @jmarkwelch.bsky.social et al. The work in this paper made me want to be a microbiologist. I vividly remember an MBL lecture by Gary Borisy on the topic when I was a grad student.
