The paper shows how oxygen gradients in the gut reshape cross-feeding between Bacteroides thetaiotaomicron and Escherichia coli through spatial organization and metabolic feedback.

This paper combines cryo-EM and FIB-SIMS to map sub-cellular chemical distributions in bacteria, revealing pollutant storage in phase-separated aggregates.

This study shows human gut bacteria can accumulate PFAS, with some species like Bacteroides uniformis accumulating them to high concentrations, and identifies mechanisms involving transmembrane transport and efflux pumps.

This study reports the 3.2 Å resolution structure of the Pseudomonas aeruginosa PAO1 Type IV pilus using cryo-EM, revealing its architecture and potential functional roles.
