    Decreased recent adaptation at human mendelian disease genes as a possible consequence of interference between advantageous and deleterious variants

    Chenlu Di et al.
    Harmful genetic variants at mendelian disease genes slow down adaptation, by interfering with the spread of adaptive variants in a population.

    Competitive binding of MatP and topoisomerase IV to the MukB hinge domain

    Gemma LM Fisher et al.
    Topoisomerase IV and the ter-binding protein MatP competitively bind the hinge domain of the Escherichia coli Structural Maintenance of Chromosomes complex, MukB, leading to spatiotemporal regulation of MukBEF-topoisomerase IV activity.

    Combination of inflammatory and vascular markers in the febrile phase of dengue is associated with more severe outcomes

    Nguyen Lam Vuong et al.
    Relationships of biomarkers with clinical outcome differed between children and adults and the best combinations associated with moderate/severe dengue comprised of six/seven vascular and immune biomarkers.

    Dynamic dichotomy of accumbal population activity underlies cocaine sensitization

    Ruud van Zessen et al.
    Cocaine elicits opposing activity changes in D1R vs D2R spiny projection neurons of the nucleus accumbens with much variability, subsequent recruitment of a subset of D1R neurons drives behavioral sensitization.

    Par3 cooperates with Sanpodo for the assembly of Notch clusters following asymmetric division of Drosophila sensory organ precursor cells

    Elise Houssin et al.
    Baz/Par3 and Sanpdo are required for clustering and activation of Notch receptors to allow intra-lineage private communication following asymmetric division of Drosophila epithelial cells.

    Utility of polygenic embryo screening for disease depends on the selection strategy

    Todd Lencz et al.
    Preimplantation screening of embryos using polygenic risk scores may substantially reduce risk for a given complex disease, but this effect depends on several quantifiable factors and raises significant ethical issues.

    Switch-like and persistent memory formation in individual Drosophila larvae

    Amanda Lesar et al.
    A new computer controlled behavioral assay and integrated training chamber for individual Drosophila larvae shows that larvae learn all at once and create long-term memories that last overnight.

    Mutational analysis to explore long-range allosteric couplings involved in a pentameric channel receptor pre-activation and activation

    Solène N Lefebvre et al.
    A pentameric channel-receptor was studied by combining allosteric mutations, electrophysiology, fluorescent reporters and normal mode analysis, to dissect the long-range allosteric couplings specifically involved in its pre-activation and activation.

    SARS-CoV-2 shedding dynamics across the respiratory tract, sex, and disease severity for adult and pediatric COVID-19

    Paul Z Chen et al.
    COVID-19 severity, rather than sex or age, predicts SARS-CoV-2 kinetics, and SARS-CoV-2 viral load from lower respiratory tract specimens may predict severe disease days before clinical deterioration for COVID-19 patients.

    Structural variability and concerted motions of the T cell receptor – CD3 complex

    Prithvi R Pandey et al.
    The orientation of the TCR extracellular domain is highly variable and coupled to characteristic structural changes throughout the TCR - CD3 complex.
