    Destructive disinfection of infected brood prevents systemic disease spread in ant colonies

    Christopher D Pull et al.
    Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.

    Impact of the scale-up of piped water on urogenital schistosomiasis infection in rural South Africa

    Frank Tanser et al.
    Scale-up of safe water supplies decreases a child's risk of urogenital schistosomiasis infection by eight-fold in a typical rural African population.

    An adaptation of astronomical image processing enables characterization and functional 3D mapping of individual sites of excitation-contraction coupling in rat cardiac muscle

    Qinghai Tian et al.
    The fusion of astronomy and cellular cardiology reveals the 3D arrangement and the firing reliability of active excitation-contraction coupling sites in beating cardiac myocytes.

    Crucial role for T cell-intrinsic IL-18R-MyD88 signaling in cognate immune response to intracellular parasite infection

    Ana-Carolina Oliveira et al.
    Development of a robust Th1 response to infection against an intracellular parasite requires T-cell intrinsic MyD88 signaling, mostly through the upstream IL-18 receptor, for the induction of genes involved in proliferation, cytokine production and migration.

    Motor thalamus supports striatum-driven reinforcement

    Arnaud L Lalive et al.
    While the basal ganglia have long been thought to mediate learning through dopamine-dependent striatal plasticity, their regulation of motor thalamus plays an unexpected and critical role in reinforcement.

    Persistent coding of outcome-predictive cue features in the rat nucleus accumbens

    Jimmie M Gmaz et al.
    Neural activity in the rat nucleus accumbens provides a rich task representation that includes not only expected outcomes, but also the specific identity of the cues that predict these outcomes.

    Mechano-redox control of integrin de-adhesion

    Freda Passam et al.
    Ligand binding, force and chemistry combine to control the function of a cell surface receptor.

    Model-based fMRI reveals dissimilarity processes underlying base rate neglect

    Sean R O'Bryan et al.
    Model-based imaging shows that the rostrolateral prefrontal cortex supports dissimilarity-based heuristics that people may use when they are confronted with ambiguous scenarios.

    Task-dependent recurrent dynamics in visual cortex

    Satohiro Tajima et al.
    A decoding-based, state-space reconstruction reveals that neurons in macaque IT cortex change the structure of their collective attractor dynamics depending on task contexts.

    Contributions of local speech encoding and functional connectivity to audio-visual speech perception

    Bruno L Giordano et al.
    Seeing a speaker's face aids comprehension by facilitating functional connectivity between the temporal and frontal lobes.
