    Structurally distributed surface sites tune allosteric regulation

    James W McCormick, Marielle AX Russo ... Kimberly A Reynolds
    Deep mutational scanning of a synthetic allosteric chimera revealed that a sparse set of mutations on the protein surface improved regulation.

    Multiple neuronal networks coordinate Hydra mechanosensory behavior

    Krishna N Badhiwala, Abby S Primack ... Jacob T Robinson
    Despite lacking traditional ganglia or centralization, the Hydra nervous system computes sensorimotor responses via localized neuron ensembles.

    Sensory coding and the causal impact of mouse cortex in a visual decision

    Peter Zatka-Haas, Nicholas A Steinmetz ... Kenneth D Harris
    Local sensory signals in visual and frontal cortex play a causal role in task performance, while widespread dorsal cortical signals correlating with movement reflect processes that do not.

    Social fluidity mobilizes contagion in human and animal populations

    Ewan Colman, Vittoria Colizza ... Shweta Bansal
    A new way of measuring sociality in human and animal contact networks reveals the link between social behavior, population density, and disease transmission.

    Distinct forms of synaptic plasticity during ascending vs descending control of medial olivocochlear efferent neurons

    Gabriel E Romero, Laurence O Trussell
    In a fast brainstem relay controlling hearing sensitivity, descending synaptic control from midbrain provides the dominant source of excitation, due to a distinct form of synaptic plasticity.

    Efficacy profile of the CYD-TDV dengue vaccine revealed by Bayesian survival analysis of individual-level phase III data

    Daniel J Laydon, Ilaria Dorigatti ... Neil M Ferguson
    Bayesian survival analysis reveals comprehensive efficacy profile and mechanism of action for Sanofi-Pasteur’s CYD-TDV dengue vaccine, whereby vaccination acts as a silent, disease-free infection enhancing disease risk in seronegatives, but giving greater immunity in seropositives than two natural infections.

    Plasmodium falciparum K13 mutations in Africa and Asia impact artemisinin resistance and parasite fitness

    Barbara H Stokes, Satish K Dhingra ... David A Fidock
    Plasmodium falciparum K13 mutations confer resistance to the antimalarial artemisinin in Asian and African parasites, with most gene-edited mutant K13 African parasite lines showing a fitness cost that may predict slow dissemination of artemisinin resistance in high-transmission settings.

    Heterochromatin-dependent transcription of satellite DNAs in the Drosophila melanogaster female germline

    Xiaolu Wei, Danna G Eickbush ... Amanda M Larracuente
    The piRNA pathway regulates satellite DNAs in the Drosophila melanogaster germline and affects heterochromatin establishment at pericentromeric satellite DNA in embryos, implying a general role for piRNAs in ensuring genome stability.

    The role of interspecies recombination in the evolution of antibiotic-resistant pneumococci

    Joshua C D'Aeth, Mark PG van der Linden ... The GPS Consortium
    Selection by national-level antibiotic consumption and vaccination trends drives atypical recombinations, frequently resulting in interspecies sequence exchange at many sites across a bacterial species’ chromosome.

    Identification of drugs associated with reduced severity of COVID-19 – a case-control study in a large population

    Ariel Israel, Alejandro A Schäffer ... Eytan Ruppin
    Large-scale retrospective analysis suggests medications and dietary supplements, such as rosuvastatin, ezetimibe, ubiquinone, risedronate, vitamin D, and magnesium, are associated with a lower rate of severe COVID-19 disease.
