Using a transparent soil mimic and the model bacterium #Ecoli, researchers characterized how soil texture affects bacterial motility across pore scales, finding bacteria shift from run-and-tumble behavior in large pores to frequent trapping in small ones.

ALT Microscopic images showing the impact of three different types of soil texture on interactions between E. coli (in green) and Arabidopsis thaliana roots (red). Panel A displays two images of E. coli overlaid on a single Arabidopsis thaliana root in silt, at zero minutes on the left and 60 minutes on the right. Panels B and C display the same in loam and sand textures, respectively. The bacterial concentration at the 60 minute mark is denoted as a function of distance with white arrows.

This was a fun piece to write. Thanks to the Aspen Center for Physics for inviting me.

Check out our new paper which describes large scale 3D simulations of M xanthus colonies. We recapitulate many features from experiments and learn some new things as well! biorxiv.org/content/10.1101/…
So happy to see this out. What a great collaboration!
Paper now out in PNAS! Our colloidal whole-cell simulations + in vivo 3D particle tracking reveal how macromolecular interactions and confinement determine dynamics/localization in E. coli. Congrats @AlpSunol & @dsvalverdem! pnas.org/doi/10.1073/pnas.24…
The Princeton Brass Band is off to the National Championships again, but we need your help! Running a world-class band, from music and instruments to rehearsal space and free concerts to our education and outreach, is not cheap. Please consider donating!

Excited to share my lab’s first preprint! We found that increasing DNA binding by type IV pili in an Acinetobacter pathogen can boost its natural transformation rates by ~100-fold, demonstrating that DNA binding is rate-limiting for natural transformation. biorxiv.org/content/10.1101/…
How do bacteria grow and move in large groups where cells appear adhered to each other but can move freely? Using capillary forces from thin layers of water! Check out our new preprint with Matt Black, Chenyi Fei, @RicardAlert and Ned Wingreen: biorxiv.org/content/10.1101/…
I’m excited to be joining PRX Life, which has the potential to be an outstanding journal in the field of biological physics. Experimentalists (!) and theorists alike, send us your most exciting work. I look forward to working with you through the review process.
Meet our newest editor, Josh Sheavitz! 👋
@shaevitz is a professor of #physics and #genomics at @Princeton, studying cell and animal behavior. He will manage manuscripts and leverage his broad expertise to improve the #PeerReview process for #interdisciplinary papers.

🎉 new preprint posted of potential interest, lead by talented masters student @AChRD4:
🔥fully unsupervised 3D cell segmentation that is as good (or better) than leading supervised methods, with @napari_imaging integration! 👏
biorxiv.org/content/10.1101/…
➕new 3D GT dataset ⬇️🧵
Have you tried #CellSeg3D yet for automating your 3D lightsheet microscopy analysis?
We just hit >75K pip installations! 🥳
We have some 🔥 coming soon ... but in the meantime, github.com/AdaptiveMotorCont… lead by @AChRD4 @Neuro_X_EPFL

P. aeruginosa uses pilus-mediated motility to invade and disperse S. aureus biofilms, rendering Sa cells susceptible to Pa antimicrobials. Without invasion Pa restricts Sa expansion forming dense Sa colonies with altered physiology @asanchezpena_
