    POMC neurons expressing leptin receptors coordinate metabolic responses to fasting via suppression of leptin levels

    Alexandre Caron et al.
    A subset of hypothalamic POMC neurons that express leptin receptors control metabolic responses to changing energy availability including regulating blood glucose and leptin levels.

    Conjunction of factors triggering waves of seasonal influenza

    Ishanu Chattopadhyay et al.
    Three complementary computational approaches reveal a set of putative causes of initiation of pan-USA waves of influenza.

    Ventral pallidal encoding of reward-seeking behavior depends on the underlying associative structure

    Jocelyn M Richard et al.
    Reward-related cues elicit phasic changes in activity in ventral pallidum neurons, which predict and functionally contribute to the speed of behaviors trained on the basis of act-outcome, but not stimulus-outcome, contingencies.

    Salient experiences are represented by unique transcriptional signatures in the mouse brain

    Diptendu Mukherjee et al.
    Inducible transcription in the brain encodes detailed aspects of recent experience.

    Transient external force induces phenotypic reversion of malignant epithelial structures via nitric oxide signaling

    Benjamin L Ricca et al.
    In a 3D culture model of breast epithelium, application of a short-timescale compression to single malignant cells promotes the long-timescale development of polarized, growth-arrested structures.

    Laminin signals initiate the reciprocal loop that informs breast-specific gene expression and homeostasis by activating NO, p53 and microRNAs

    Saori Furuta et al.
    Endogenous laminins are necessary to build a functional acinus via generating NO, activating p53, HOXD10 and other positive players, but tumor cells neither make laminin nor generate NO, unless they are reverted to an organized structure.

    A switch in transcription and cell fate governs the onset of an epigenetically-deregulated tumor in Drosophila

    Joana Torres et al.
    A previously unknown oncogenic feature of an embryonic transcription factor was uncovered from transcriptomic analysis of tumors that lack functional Polycomb silencing.

    Distinct contributions of functional and deep neural network features to representational similarity of scenes in human brain and behavior

    Iris IA Groen et al.
    Deep network features exhibit a robust correlation with brain activity in scene-selective cortex, but are not sufficient to explain human scene categorization behavior, which is strongly shaped by information about the function (possibility for action) of the scene.

    SIRT2 deacetylase regulates the activity of GSK3 isoforms independent of inhibitory phosphorylation

    Mohsen Sarikhani et al.
    Mass spectroscopy, molecular modeling and/or molecular dynamics simulations reveal how acetylation regulates the activity of GSK3 isoforms independent of inhibitory phosphorylation.

    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.
