E. coli do not count single molecules

The paper shows E. coli chemosensing is limited by internal noise, not physical molecule diffusion limits, using information rate analysis.

Lattice ultrasensitivity amplifies signals in E. coli without fine-tuning

This paper introduces a new model of E. coli chemosensory lattice signal processing called lattice ultrasensitivity, which achieves high gain without requiring fine-tuning.

Direct measurement of dynamic attractant gradients reveals breakdown of the Patlak-Keller-Segel chemotaxis model

The paper measures dynamic attractant gradients in bacteria and shows the Patlak-Keller-Segel model fails at high cell densities, proposing an improved model that accounts for cell density effects.

Novelty detection and multiple timescale integration drive Drosophila orientation dynamics in temporally diverse olfactory environments

This study investigates how Drosophila navigates odor plumes by analyzing the impact of odor timing on orientation dynamics and finds that flies use a combination of frequency-dependent responses and two-timescale filtering.

Optimal inference of molecular interactions in live FRET imaging

This paper introduces B-FRET, a Bayesian framework for inferring molecular interactions from live FRET imaging data, improving signal-to-noise ratio without additional measurements.

A mechanism for migrating bacterial populations to non-genetically adapt to new environments

The paper shows that bacterial populations non-genetically adapt their phenotype composition during migration to enhance growth in new environments.

E. coli chemotaxis is information-limited

This study quantifies how information limits E. coli chemotaxis performance, finding that cells operate near theoretical efficiency despite using less than 1 bit of information.

Modulation of Flagellar Rotation in Surface-Attached Bacteria: A Circuit for Rapid Surface-Sensing

The paper investigates how Pseudomonas aeruginosa modulates flagellar rotation after surface attachment, revealing a role for FlhF and cAMP signaling in controlling motor behavior.

Spatial Self-Organization Resolves Conflicts Between Individuality and Collective Migration

The paper studies how clonal Escherichia coli cells maintain collective migration despite individual differences in chemotactic ability through spontaneous spatial sorting within the moving band.
