    Early prediction of level-of-care requirements in patients with COVID-19

    Boran Hao et al.
    Using data for 2566 COVID-19 patients from five hospitals, models are developed to predict for each patient hospitalization and critical care needs, based on demographics, comorbidities, medications, and laboratory findings.

    A single mutation in Crimean-Congo hemorrhagic fever virus discovered in ticks impairs infectivity in human cells

    Brian L Hua et al.
    Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.

    Synchronous activity patterns in the dentate gyrus during immobility

    Martin Pofahl et al.
    Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.

    Estimating SARS-CoV-2 seroprevalence and epidemiological parameters with uncertainty from serological surveys

    Daniel B Larremore et al.
    Integrating over multiple forms of statistical uncertainty associated with serological surveys can improve serosurvey design while also enabling that uncertainty to be appropriately propagated through epidemiological models.

    Late-life restoration of mitochondrial function reverses cardiac dysfunction in old mice

    Ying Ann Chiao et al.
    Mitochondrial-targeted SS-31 peptide ameliorates mitochondrial dysfunction and rescues pre-existing cardiac dysfunction in old mice, supporting the translational potential of mitochondrial protective interventions to treat age-related diseases.

    Extrinsic activin signaling cooperates with an intrinsic temporal program to increase mushroom body neuronal diversity

    Anthony M Rossi, Claude Desplan
    The activin ligand myoglianin acts as a temporal extrinsic cue to regulate the intrinsic temporal factor Imp in mushroom body neuroblasts, increasing neuronal diversity by specifying the α’β’ fate.

    Emergence and diversification of a host-parasite RNA ecosystem through Darwinian evolution

    Taro Furubayashi et al.
    In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.
