    Evolutionary pathways to antibiotic resistance are dependent upon environmental structure and bacterial lifestyle

    Alfonso Santos-Lopez et al.
    Bacteria growing in biofilms evolve antimicrobial resistance via different pathways and generate greater genetic diversity than well-mixed populations, selecting fitter but less resistant genotypes.

    Heterogeneity in surface sensing suggests a division of labor in Pseudomonas aeruginosa populations

    Catherine R Armbruster et al.
    Subpopulations of polysaccharide producer and surface explorer cells play specialized roles in early Pseudomonas aeruginosa biofilm formation.

    A multiphase theory for spreading microbial swarms and films

    Siddarth Srinivasan et al.
    A multiphase hydrodynamic theory reveals that the dynamics of colony expansion in microbial swarms and biofilms are limited by the constraints of water and nutrient availability.

    Mechanistic insight into the conserved allosteric regulation of periplasmic proteolysis by the signaling molecule cyclic-di-GMP

    Debashree Chatterjee et al.
    Structure-function analyses reveal the mechanistic underpinnings of inside-out transmembrane signaling that controls periplasmic proteolysis, and thereby biofilm formation, in bacteria and may be relevant in the context of other signaling proteins with similar control elements.

    A serine sensor for multicellularity in a bacterium

    Arvind R Subramaniam et al.
    Biofilm formation by Bacillus subtilis relies on a sensing mechanism for the amino acid serine that does not depend on a dedicated protein or RNA.

    Differential interaction forces govern bacterial sorting in early biofilms

    Enno R Oldewurtel et al.
    Differential physical interactions between bacteria in mixed microcolonies trigger cell sorting.

    Bacterial Evolution: The road to resistance

    Devon M Fitzgerald
    The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.

    Strong inter-population cooperation leads to partner intermixing in microbial communities

    Babak Momeni et al.
    Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.

    Kin discrimination in social yeast is mediated by cell surface receptors of the Flo11 adhesin family

    Stefan Brückner et al.
    Structural, biophysical and physiological analysis reveals how yeast cell surface adhesins evolved to confer self-nonself discrimination in single cells and whole populations.

    Coincidence detection and bi-directional transmembrane signaling control a bacterial second messenger receptor

    Richard B Cooley et al.
    Building on previous work (Chatterjee et al., 2014), the mechanism of coincidence detection in bacterial second messenger signaling across membranes is revealed at a molecular level, providing insight into the regulation of a conserved transmembrane receptor.
