    β-cell intrinsic dynamics rather than gap junction structure dictates subpopulations in the islet functional network

    Jennifer K Briggs, Anne Gresch ... Richard KP Benninger
    The functional network of β-cells in the pancreatic islet, which has been used to identify important subpopulations of β-cells implicated in diabetes progression, is indicative of intrinsic dynamics rather than structural communication, implying islet robustness.

    Passive accumulation of alkaloids in inconspicuously colored frogs refines the evolutionary paradigm of acquired chemical defenses

    Rebecca D Tarvin, Jeffrey L Coleman ... Richard W Fitch
    The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.

    A paternal bias in germline mutation is widespread in amniotes and can arise independently of cell division numbers

    Marc de Manuel, Felix L Wu, Molly Przeworski
    A paternal bias in germline mutation is seen throughout amniotes and may be explained by sex differences in DNA damage and repair after primordial germ cell specification.

    Data-driven, participatory characterization of farmer varieties discloses teff breeding potential under current and future climates

    Aemiro Bezabih Woldeyohannes, Sessen Daniel Iohannes ... Matteo Dell'Acqua
    A genomic, climatic, agronomic, and participatory characterization of teff agrobiodiversity shows opportunities and challenges of teff improvement in the face of climate change.

    Kinase-dead ATM protein is highly oncogenic and can be preferentially targeted by Topo-isomerase I inhibitors

    Kenta Yamamoto, Jiguang Wang ... Shan Zha
    Orphan ATM kinase-domain missense mutations are unexpectedly common and form a potent oncogenic event and a biomarker for Topo-isomerase I inhibitor based therapy.

    A non-mosaic transchromosomic mouse model of Down syndrome carrying the long arm of human chromosome 21

    Yasuhiro Kazuki, Feng J Gao ... Roger H Reeves
    TcMAC21 is an appropriate “next gen” mouse model for DS research, and provides a proof of concept of using artificial chromosomes to generate non-mosaic humanized animal models of chromosome disorders.

    The primary structural photoresponse of phytochrome proteins captured by a femtosecond X-ray laser

    Elin Claesson, Weixiao Yuan Wahlgren ... Sebastian Westenhoff
    Time-resolved crystallography provides insight into the photochemical reactions in photoreceptor proteins, explaining the earliest steps of how plants, fungi and bacteria sense red light.

    BRCA2 BRC missense variants disrupt RAD51-dependent DNA repair

    Judit Jimenez-Sainz, Joshua Mathew ... Ryan B Jensen
    Novel variants in the BRC repeat region of BRCA2 were identified and comprehensively characterized as either deleterious or benign.

    Subthalamic, not striatal, activity correlates with basal ganglia downstream activity in normal and parkinsonian monkeys

    Marc Deffains, Liliya Iskhakova ... Hagai Bergman
    The spiking activity of the subthalamic nucleus, rather than the activity of striatal projection neurons, orchestrates basal ganglia downstream activity and output commands in health and Parkinson’s disease.

    Determining the effects of paternal obesity on sperm chromatin at histone H3 lysine 4 tri-methylation in relation to the placental transcriptome and cellular composition

    Anne-Sophie Pepin, Patrycja A Jazwiec ... Sarah Kimmins
    Epigenomic and transcriptomic analysis reveals that paternal obesity influences sperm histone H3 lysine 4 tri-methylation enrichment and placenta gene expression, which in turn negatively impact its development and function in a manner that may contribute to metabolic disease in offspring.
