    Neural representation of abstract task structure during generalization

    Avinash R Vaidya, Henry M Jones ... David Badre
    The human brain maintains a representation of latent task states within frontoparietal networks during the generalization of behaviors to novel settings.

    HPF1 and nucleosomes mediate a dramatic switch in activity of PARP1 from polymerase to hydrolase

    Johannes Rudolph, Genevieve Roberts ... Karolin Luger
    The polymerase activity of PARP1 is converted to hydrolase activity upon binding of Histone Parylation Factor 1 (HPF1) with nucleosome activators.

    Topological signatures in regulatory network enable phenotypic heterogeneity in small cell lung cancer

    Lakshya Chauhan, Uday Ram ... Mohit Kumar Jolly
    Network topology and gene expression patterns in small cell lung cancer reveal two mutually opposing teams of regulators that enable multistability and consequent non-genetic heterogeneity, a clinically unsolved challenge.

    Parathyroid hormone attenuates osteoarthritis pain by remodeling subchondral bone in mice

    Qi Sun, Gehua Zhen ... Xu Cao
    Parathyroid hormone attenuates osteoarthritis pain and joint degeneration by modification of subchondral bone remodeling and could be a potential disease-modifying therapy for osteoarthritis.

    Synaptotagmin-7 places dense-core vesicles at the cell membrane to promote Munc13-2- and Ca2+-dependent priming

    Bassam Tawfik, Joana S Martins ... Jakob Balslev Sørensen
    Synaptotagmin-7 acts synergistically with synaptotagmin-1 by placing vesicles close to the plasma membrane within reach of the SNARE/Munc13-complex, supporting their priming and setting the stage for fast and slow fusion.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm, Matthias Platzer ... Philip Dammann
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    Somatostatin interneurons activated by 5-HT2A receptor suppress slow oscillations in medial entorhinal cortex

    Roberto de Filippo, Benjamin R Rost ... Dietmar Schmitz
    Somatostatin interneurons are novel mediators of serotonergic modulation in entorhinal cortex via activation of 5-HT2A receptors, a receptor involved in the etiology of different psychiatric disorders.

    The dimeric Golgi protein Gorab binds to Sas6 as a monomer to mediate centriole duplication

    Agnieszka Fatalska, Emma Stepinac ... David M Glover
    The dual functional protein, Gorab, associates with the Golgi as a dimer but as a monomer with the procentriole cartwheel protein, Sas6, to mediate centriole duplication.

    Tuning self-renewal in the Arabidopsis stomatal lineage by hormone and nutrient regulation of asymmetric cell division

    Yan Gong, Julien Alassimone ... Dominique C Bergmann
    Quantitative live-cell time-lapse imaging reveals that the spatial and temporal degree of cortical polarity domains reflects stem-cell division capacity in cells of the Arabidopsis plant leaf epidermis.

    Selenium supplementation inhibits IGF-1 signaling and confers methionine restriction-like healthspan benefits to mice

    Jason D Plummer, Spike DL Postnikoff ... Jay E Johnson
    Dietary selenium supplementation confers to mice all of the short-term healthspan benefits of the longevity-promoting intervention methionine restriction, and thus may represent a method to promote healthy aging in mammals.
