Single-cell imaging of the lytic phage life cycle in bacteria

This study uses time-lapse imaging to analyze phage infection dynamics in bacteria, revealing heterogeneity and its impact on phage fitness.

Phenotypic plasticity shapes biofilm's structure and fluid transport enhancing resilience

The paper investigates how phenotypic plasticity in Bacillus subtilis biofilms enhances resilience through spatial organization and fluid transport properties.

Impact of crowding on the diversity of expanding populations

The paper quantifies how crowding affects genetic diversity in expanding microbial populations by showing a power-law distribution of low-frequency clones due to volume-exclusion interactions.

Superinfection exclusion: a viral strategy with short-term benefits and long-term drawbacks

This study shows that superinfection exclusion benefits viruses in the short-term by promoting beneficial mutations and removing deleterious ones, but can hinder long-term adaptation.

Range expansion shifts clonal interference patterns in evolving populations

This study examines how range expansion affects clonal interference patterns in evolving populations, finding that mutant fixation dynamics vary with population size, mutation rate, and spatial structure.

Virus-host interactions shape viral dispersal giving rise to distinct classes of travelling waves in spatial expansions

This study shows that bacteriophage T7 exhibits density-dependent dispersal due to host interactions, leading to a transition from pulled to pushed reaction-diffusion waves in spatial expansions.

Collective motion conceals fitness differences in crowded cellular populations

The paper shows that collective motion in crowded yeast populations masks fitness differences, allowing deleterious mutations to persist and increase their chance of evolutionary rescue.
