The paper shows how two small proteins, SafA and MgrB, work together with magnesium to control the PhoQ/PhoP signaling system in E. coli, enhancing sensitivity to environmental changes.

This study shows motile bacteria induce segregation of non-motile cells in confined flow, leading to asymmetric biofilm formation through a physical mechanism involving rheotactic drift and sedimentation.

This study examines how E. coli bacteria form different patterns in evaporating droplets based on their activity and environmental conditions, revealing three types of self-organization.

This study uses experimental evolution to test the necessity of chemotaxis pathway components in E. coli, finding that core components are essential but some auxiliary proteins can be compensated for.

This study shows that a single MCP deletion in Shewanella putrefaciens enhances chemotaxis in structured environments with minimal metabolic cost.

The paper shows that bacterial investment in flagellar motility is constrained by hydrodynamics and fitness costs, with E. coli strains maximizing motility under nutrient-rich conditions.

The paper studies T9SS-driven bacterial swarms, showing they transition through phase changes to form scattered microcolonies, reducing competition in the oral microbiota.

The paper characterizes noise sources in the Escherichia coli chemotaxis pathway using single-cell FRET and fluctuation-dissipation theorem analysis, revealing methylation-independent thermal fluctuations and receptor interactions contribute significantly to activity noise.
