    Structural color in Junonia butterflies evolves by tuning scale lamina thickness

    Rachel C Thayer et al.
    Artificial selection on wing color and CRISPR/Cas9 knockout of the optix gene both alter scale lamina thickness in Junonia coenia, which shifts structural color wavelength and mimics macroevolutionary butterfly diversity.

    The skin microbiome facilitates adaptive tetrodotoxin production in poisonous newts

    Patric M Vaelli et al.
    Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.

    Diminished responses to bodily threat and blunted interoception in suicide attempters

    Danielle C DeVille et al.
    People who have attempted suicide exhibit blunted sensory processing during breathing and pain perturbations, as well as lower heartbeat perception accuracy and reduced mid/posterior insula activity during interoceptive attention.

    A protein quality control pathway at the mitochondrial outer membrane

    Meredith B Metzger et al.
    Temperature-sensitive mitochondrial outer membrane proteins used as novel quality control substrates reveal a unique mitochondria-associated degradation pathway consisting of both cytosolic and mitochondrial ubiquitin-proteasome system machinery.

    Reversible promoter methylation determines fluctuating expression of acute phase proteins

    Shi-Chao Zhang et al.
    DNA methylation status can be exploited to finely and reversibly tune the expression of highly inducible genes with CpG-poor promoters in response to environmental cues.

    Incomplete vesicular docking limits synaptic strength under high release probability conditions

    Gerardo Malagon et al.
    The probability of occupancy of individual synaptic release sites at rest sets an upper limit to synaptic output when increasing action potential related calcium entry.

    An atypical DYRK kinase connects quorum-sensing with posttranscriptional gene regulation in Trypanosoma brucei

    Mathieu Cayla et al.
    A trypanosome DYRK kinase that exhibits fundamental differences to conventional DYRK family regulation links parasite quorum sensing, signal transduction and developmental gene expression.

    Social structure learning in human anterior insula

    Tatiana Lau et al.
    A domain-general structure learning mechanism, supported by anterior insula, moves beyond explicit category labels and dyadic similarity as the sole inputs to social group representations and predicts ally-choice behavior.

    Increase of circulating IGFBP-4 following genotoxic stress and its implication for senescence

    Nicola Alessio et al.
    Protein IGFBP-4 acts as a genotoxic stress mediator that, entering into circulation after its secretion by senescent cells, could promote further senescence phenomena in non-injured cells thus impairing tissues’ homeostasis.

    Endogenous siRNAs promote proteostasis and longevity in germline-less Caenorhabditis elegans

    Moran Cohen-Berkman et al.
    Endo-siRNAs slow down the rate of aging and enable the maintenance of a responsive heat shock response in aging germline-less Caenorhabditis elegans.
