What a phenomenal seminar today at @CornellPathogen by @Hatzios_Lab — a tour de force of using chemical proteomics to discover new mechanisms of redox signaling in gut infection!🤩🤩🤩

Our new paper out in @PLOSPathogens today: dx.plos.org/10.1371/journal.… We find that resistance/tolerance to antimicrobial peptides is slightly more complex and dynamic than your "average" antibiotic resistance. Nice work by @AndyMurtha et al.!

We demonstrated a lowcost device that can detect deadly bacteria in drinking water. It shows, once again, that worldclass research can flourish in Nepal, despite limited resources. Here is news release by @OpticaWorldwide highlighting the important result. optica.org/about/newsroom/ne…

Announcing the 2025 Bacterial and Archaeal Cell Biology and Development @GordonConf. We have amazing speakers and discussion leaders confirmed and look forward to (again) having our minds blown by all the remarkable science. Applications will start being accepted in the fall.

And that concludes our workshop in Nepal! Successfully cloned NDM carbapenemases? Check! Isolated bacteria that can eat styrofoam and motor oil from Bagmati River AND fluoresce under UV? Check! @rajbhandari_33 @karmamonima @guavadk @utsavRIBB @AnkitSh03786959

I asked AI to draw an image of the bacterial OM. This is what it came up with. My lab better pivot to the new hot field of outer pemmoccan homeostasis! And how is that one otter equally distributed among daughter cells? Lots of cool open questions!
