    Mitochondrial temperature homeostasis resists external metabolic stresses

    Mügen Terzioglu, Kristo Veeroja ... Howard T Jacobs
    Based on two independent methods, mitochondria operate at temperatures up to 15°C hotter than ambient, adjusting their heat production so as to maintain temperature in face of physiological stresses.

    Assessing drug safety by identifying the axis of arrhythmia in cardiomyocyte electrophysiology

    Stewart Heitmann, Jamie I Vandenberg, Adam P Hill
    A novel mathematical method for screening new drugs for pro-arrhythmic cardiotoxicity without using animals or costly drug-specific computer simulations is proposed.

    Effort cost of harvest affects decisions and movement vigor of marmosets during foraging

    Paul Hage, In Kyu Jang ... Reza Shadmehr
    When the acquisition of reward becomes effortful, marmosets choose to work longer, delaying their harvest, but slow their movements, reducing energy consumption.

    A positive feedback loop between ZEB2 and ACSL4 regulates lipid metabolism to promote breast cancer metastasis

    Jiamin Lin, Pingping Zhang ... Na Yang
    The ZEB2/ACSL4 axis acts as a novel metastatic metabolic pathway that stimulates both lipogenesis and fatty acid oxidation, resulting in enhanced breast cancer invasion and metastasis.

    A neural network model of hippocampal contributions to category learning

    Jelena Sučević, Anna C Schapiro
    A neural network model of the hippocampus exhibits a division of labor across its two main pathways during category learning, with one pathway specializing in extracting systematic category information and another in encoding arbitrary details.

    Shh from mossy cells contributes to preventing NSC pool depletion after seizure-induced neurogenesis and in aging

    Hirofumi Noguchi, Jessica Chelsea Arela ... Samuel Pleasure
    Hilar mossy cells control seizure-dependent dentate neurogenesis and stem cell quiescence by activity-dependent control of Sonic hedgehog production and signaling.

    Evolution towards simplicity in bacterial small heat shock protein system

    Piotr Karaś, Klaudia Kochanowicz ... Krzysztof Liberek
    Phylogenetic and biochemical analysis reveals crucial role of two substitutions in the α–crystallin domain for development of new functionality of IbpA chaperone after the loss of paralogous IbpB in Erwiniaceae.

    Enterobacterales plasmid sharing amongst human bloodstream infections, livestock, wastewater, and waterway niches in Oxfordshire, UK

    William Matlock, Samuel Lipworth ... REHAB Consortium
    A geographically and temporally restricted genomic surveillance study concludes that Enterobacterales plasmid dissemination between human and non-human niches might be occurring at greater rates than previously estimated.

    ACC neural ensemble dynamics are structured by strategy prevalence

    Mikhail Proskurin, Maxim Manakov, Alla Karpova
    Anterior Cingulate Cortex displays robust tracking during strategy execution of a summary statistic for that strategy in recent behavioral history, suggesting a role for this brain region in estimating which actions promote the occurrence of events in the environment.

    Differential regulation of hair cell actin cytoskeleton mediated by SRF and MRTFB

    Ling-Yun Zhou, Chen-Xi Jin ... Hao Wu
    In hair cells, the development and maintenance of the F-actin-enriched stereocilia and cuticular plates are differentially regulated by transcription factors SRF and MRTFB, and SRF–CNN2 is required for modulating actin dynamics of the stereocilia and cuticular plate.
