    Countercurrent heat exchange and thermoregulation during blood-feeding in kissing bugs

    Chloé Lahondère et al.
    A novel thermoregulatory mechanism in blood-sucking insects, vectors of human disease, is described using a functional-morphological approach.

    Dopamine receptor 1 neurons in the dorsal striatum regulate food anticipatory circadian activity rhythms in mice

    Christian M Gallardo et al.
    For mice, knowing when it is time to feed is dependent on the neurotransmitter dopamine and the D1R receptor of neurons in the dorsal striatum.

    Oxygen isotopes suggest elevated thermometabolism within multiple Permo-Triassic therapsid clades

    Kévin Rey et al.
    Two therapsid clades, dicynodonts and cynodonts, independently acquired and developed an endotherm-like thermoregulation during the Late Permian period, that probably helped them to survive the major global climate and environmental fluctuations of the end-Permian.

    Thermoregulation: Bugs battle stress from hot blood

    Joshua B Benoit, David L Denlinger
    A heat exchange mechanism in the head of kissing bugs helps to prevent stress and regulate their temperature while they feed on warm blood.

    Arcuate nucleus and lateral hypothalamic CART neurons in the mouse brain exert opposing effects on energy expenditure

    Aitak Farzi et al.
    CART exerts differential metabolic effects in response to activation of neurons of the Arc, where CART suppresses energy expenditure, while it enforces the reward characteristics of the LHA.

    Structural basis of malodour precursor transport in the human axilla

    Gurdeep S Minhas et al.
    Discovery of the structural basis for recognition and uptake of a human precursor for body odour production reveals an important role for bacterial peptide transport and novel routes to prevent its production in humans.

    A multi-scale model for hair follicles reveals heterogeneous domains driving rapid spatiotemporal hair growth patterning

    Qixuan Wang et al.
    Regional differences in activator and inhibitor signals alter hair cycle pace across mouse skin and produce unique fur renewal 'landscapes', with fastest renewal on the ventrum and slowest renewal on the ear pinnae.

    Neurosecretory protein GL stimulates food intake, de novo lipogenesis, and onset of obesity

    Eiko Iwakoshi-Ukena et al.
    Neurosecretory protein GL, a previously unknown mammalian neuropeptide, is a novel hypothalamic factor which regulates feeding behavior and peripheral lipogenesis in animals.

    Inhibitory peptidergic modulation of C. elegans serotonin neurons is gated by T-type calcium channels

    Kara E Zang et al.
    Genetic analysis of how neuropeptides control C. elegans reproductive behavior shows how T-type calcium channels engage and disengage target neurons from these critical regulators of neural circuits and behavior.

    Automated analysis of long-term grooming behavior in Drosophila using a k-nearest neighbors classifier

    Bing Qiao et al.
    Drosophila grooming is driven by two internal programs.
