Widespread attraction of marine bacteria to the macroalgae-derived polysaccharide fucoidan

This study shows marine bacteria are attracted to fucoidan at high concentrations, suggesting it guides them to macroalgal surfaces, influencing carbon cycling.

Single-cell approach dissecting agr quorum sensing dynamics in Staphylococcus aureus

The paper uses single-cell techniques to study agr quorum sensing dynamics in Staphylococcus aureus, revealing differences in AIP sensitivity and community interaction patterns across agr-types.

Opposing range-dependent interactions create complex spatial patterns of antibiotic tolerance in multispecies biofilms

The paper shows that opposing range-dependent interactions between microbial exoproducts create complex spatial patterns of antibiotic tolerance in biofilms.

Limits to the evolution of metabolic dependence in spatially structured microbial communities

The paper investigates how auxotrophic mutants in E. coli populations grow in spatially structured communities, finding that growth is constrained by amino acid leakage and clustering.

Dimalis: A complete standalone pipeline to analyse prokaryotic cell growth from time-lapse imaging

Dimalis automates the analysis of bacterial cell growth from time-lapse imaging, providing standardized outputs for downstream processing.
