    Colour polymorphism associated with a gene duplication in male wood tiger moths

    Melanie N Brien, Anna Orteu ... Johanna Mappes
    A complex colour polymorphism which links colour with behavioural and life-history traits is associated with a single gene duplication in male wood tiger moths.

    Organic electrochemical transistor arrays for real-time mapping of evoked neurotransmitter release in vivo

    Kai Xie, Naixiang Wang ... Peng Shi
    An implantable device based on organic electrochemical transistors is developed for quantitative mapping of neurotransmitter release across multiple brain regions, revealing a cross-talk between the mesolimbic and nigrostriatal dopaminergic pathways.

    RIM is essential for stimulated but not spontaneous somatodendritic dopamine release in the midbrain

    Brooks G Robinson, Xintong Cai ... Pascal S Kaeser
    Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.

    Environmental pH signals the release of monosaccharides from cell wall in coral symbiotic alga

    Yuu Ishii, Hironori Ishii ... Shinichiro Maruyama
    Coral symbiotic alga is capable of degrading the own cell wall components by cellulase-related enzymes and releasing sugars as a simple and autonomous environmental response, even when the host-derived signals are not present.

    Extracellular electron transfer increases fermentation in lactic acid bacteria via a hybrid metabolism

    Sara Tejedor-Sanz, Eric T Stevens ... Maria L Marco
    Lactic acid bacteria engage a hybrid metabolism which blends features of fermentation and respiration when they perform extracellular electron transfer.

    VO2max prediction based on submaximal cardiorespiratory relationships and body composition in male runners and cyclists: a population study

    Szczepan Wiecha, Przemysław Seweryn Kasiak ... Andrzej Klusiewicz
    VO2max in endurance athletes can be accurately predicted by the submaximal cardiopulmonary exercise testing measurements but relying solely on somatic variables allows limited accuracy, which is especially important for physicians and fitness practitioners for proper health and training status monitoring.

    Recreating the synthesis of starch granules in yeast

    Barbara Pfister, Antoni Sánchez-Ferrer ... Samuel C Zeeman
    Yeast cells can be engineered to study starch, the semi-crystalline storage carbohydrate from plants that is central to human nutrition.

    Expanding xylose metabolism in yeast for plant cell wall conversion to biofuels

    Xin Li, Vivian Yaci Yu ... Jamie HD Cate
    Parallel pathways of xylose metabolism identified in fungi that grow on plants can be used in yeast to promote hemicellulose conversion to biofuels.

    Hypothalamic melanin concentrating hormone neurons communicate the nutrient value of sugar

    Ana I Domingos, Aylesse Sordillo ... Jeffrey M Friedman
    Natural sugars are preferred over artificial sweeteners because of their nutritional content, which is sensed by MCH neurons in the lateral hypothalamus.

    Functional diversity of dopamine axons in prefrontal cortex during classical conditioning

    Kenta Abe, Yuki Kambe ... Tatsuo Sato
    Two-photon calcium imaging revealed that many mesocortical dopamine axons show enhanced selectivity for aversive cue processing during classical conditioning.
