    A scenario for an evolutionary selection of ageing

    Tristan Roget, Claire Macmurray ... Michael Rera
    Ageing is broadly accepted as a by-product of evolution, as thus, models allowing to conceive ageing as an adaptive force of evolution could show significant importance at a time of biogerontology mostly aiming at curing ageing.

    The evolution of strategy in bacterial warfare via the regulation of bacteriocins and antibiotics

    Rene Niehus, Nuno M Oliveira ... Kevin R Foster
    Evolutionary game theory identifies reciprocation as a key winning strategy for warring bacteria.

    Density-dependent resistance protects Legionella pneumophila from its own antimicrobial metabolite, HGA

    Tera C Levin, Brian P Goldspiel, Harmit S Malik
    Legionella pneumophila can be inhibited by its own antimicrobial, HGA (homogentisic acid), but its density-dependent resistance to HGA restricts the potential for self-harm.

    Microbiome-pathogen interactions drive epidemiological dynamics of antibiotic resistance: A modeling study applied to nosocomial pathogen control

    David RM Smith, Laura Temime, Lulla Opatowski
    A novel mathematical modeling framework for antibiotic-resistant bacteria combining within-host microbiome-pathogen interactions with population-level pathogen epidemiology, demonstrating how antibiotic consumption and ecological competition come together to drive the spread of resistance.

    Acidic pH and divalent cation sensing by PhoQ are dispensable for systemic salmonellae virulence

    Kevin G Hicks, Scott P Delbecq ... Samuel I Miller
    Receptor recognition of antimicrobial peptides is important for Salmonellae to survive inside macrophages and cause disease.

    Discovery of coordinately regulated pathways that provide innate protection against interbacterial antagonism

    See-Yeun Ting, Kaitlyn D LaCourse ... Joseph D Mougous
    Pseudomonas aeruginosa defends against interbacterial antagonism through the coordinated expression of previously uncharacterized pathways that grant threat-specific protection.

    Eco-evolutionary dynamics of nested Darwinian populations and the emergence of community-level heredity

    Guilhem Doulcier, Amaury Lambert ... Paul B Rainey
    Artificial selection on communities drives the evolution of interactions and establishes community-level inheritance.

    Topoisomerase VI senses and exploits both DNA crossings and bends to facilitate strand passage

    Timothy J Wendorff, James M Berger
    The engagement of DNA crossings is shown to license ATP hydrolysis and DNA cleavage by topoisomerase VI, a finding with mechanistic ramifications for related GHKL ATPases and meiotic recombination machineries.

    Microbial consortia at steady supply

    Thibaud Taillefumier, Anna Posfai ... Ned S Wingreen
    In a consumer-resource model obeying the physical requirement of flux conservation, metabolic competition between microbes yields consortia of cell types that collectively resist invasion via optimal use of resources.

    Antagonism between killer yeast strains as an experimental model for biological nucleation dynamics

    Andrea Giometto, David R Nelson, Andrew W Murray
    Like physical systems that exhibit nucleation phenomena, an invading population of a strong microbial antagonist requires a critical inoculum size to successfully invade a population of a weaker microbial antagonist.
