    NHR-14 loss of function couples intestinal iron uptake with innate immunity in C. elegans through PQM-1 signaling

    Malini Rajan et al.
    Nuclear receptor NHR-14 regulates the subcellular localization of the zinc transcription factor PQM-1 to coordinate innate immunity with iron sequestration during pathogen infection in C. elegans..

    B cell receptor and Toll-like receptor signaling coordinate to control distinct B-1 responses to both self and the microbiota

    Lieselotte SM Kreuk et al.
    Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.

    Algal-fungal symbiosis leads to photosynthetic mycelium

    Zhi-Yan Du et al.
    The capacity for symbiosis between photosynthetic microalgae and early diverging lineages fungi was demonstrated with microscopy and stable isotope exchange of carbon and nitrogen.

    Metabolic network percolation quantifies biosynthetic capabilities across the human oral microbiome

    David B Bernstein et al.
    A novel metabolic network analysis method enables large-scale computational predictions of biosynthetic capabilities across the human oral microbiome, revealing a unique cluster of fastidious microorganisms and potential metabolic interdependencies.

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

    Tera C Levin et al.
    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.

    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm et al.
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

    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.

    Enterococcus faecium secreted antigen A generates muropeptides to enhance host immunity and limit bacterial pathogenesis

    Byungchul Kim et al.
    Enterococci faecium encodes unique peptidoglycan composition and remodeling activity that activates host immunity.
