    Variable opportunities for outcrossing result in hotspots of novel genetic variation in a pathogen metapopulation

    Anna-Liisa Laine et al.
    In natural pathogen populations opportunities for sexual outcrossing vary, leading to spatial variation in genetic diversity and between-season survival.

    Sparse genetic tracing reveals regionally specific functional organization of mammalian nociceptors

    William Olson et al.
    Single-nociceptor tracing reveals a novel somatotopic organization for the mammalian pain system, and physiological recordings and peripheral optogenetic behavior assays suggest that it is a possible mechanism underlying region-specific pain sensation.

    Computation identifies structural features that govern neuronal firing properties in slowly adapting touch receptors

    Daine R Lesniak et al.
    Computer simulations show that the firing patterns of branched touch receptors can be set in part by the organization of their sensory endings in the skin.

    The signaling lipid sphingosine 1-phosphate regulates mechanical pain

    Rose Z Hill et al.
    Constitutive sphingosine 1-phosphate signaling via the G-protein coupled receptor S1PR3 in mechanonociceptive somatosensory neurons is required for normal behavioral responses to noxious mechanical stimuli.
