    Modeling of axonal endoplasmic reticulum network by spastic paraplegia proteins

    Belgin Yalçın, Lu Zhao ... Cahir J O'Kane
    Proteins of the reticulon and REEP families, homologous to the products of human Hereditary Spastic Paraplegia disease genes, contribute to shaping and continuity of the axonal endoplasmic reticulum network in Drosophila.

    A model-based analysis of the health impacts of COVID-19 disruptions to primary cervical screening by time since last screen for current and future disruptions

    Emily A Burger, Inge MCM de Kok ... Megan A Smith
    Despite the overall impact of COVID-19-related cervical cancer screening disruptions on cervical cancer outcomes being small, disruptions disproportionately affect underscreened women, underpinning the importance of reaching such women as a critical area of focus, regardless of temporary disruptions.

    Inferring multi-scale neural mechanisms with brain network modelling

    Michael Schirner, Anthony Randal McIntosh ... Petra Ritter
    Hybrid brain network models predict neurophysiological processes that link structural and functional empirical data across scales and modalities in order to better understand neural information processing and its relation to brain function.

    Temporal derivative computation in the dorsal raphe network revealed by an experimentally driven augmented integrate-and-fire modeling framework

    Emerson F Harkin, Michael B Lynn ... Jean-Claude Béïque
    A new type of biologically constrained spiking neural network model applied to the dorsal raphe nucleus shows that the output of the serotonin system reflects not just its raw input, but mainly how quickly its input changes over time.

    Projected resurgence of COVID-19 in the United States in July—December 2021 resulting from the increased transmissibility of the Delta variant and faltering vaccination

    Shaun Truelove, Claire P Smith ... Cecile Viboud
    Multi-model ensembling projected that the Delta variant would lead to a substantial COVID-19 resurgence in the US, with higher vaccination uptake being a critical factor for limiting transmission and impact between states.

    Leading edge maintenance in migrating cells is an emergent property of branched actin network growth

    Rikki M Garner, Julie A Theriot
    Computational simulations of actin network growth at the cell leading edge, combined with careful high-speed video microscopy measurements of leading edge shape fluctuations, suggest that Arp2/3 branching of the actin network occurs at an optimal angle to minimize fluctuations.

    Network instability dynamics drive a transient bursting period in the developing hippocampus in vivo

    Jürgen Graf, Vahid Rahmati ... Knut Kirmse
    Two-photon Ca2+ imaging and computational modeling reveal major developmental trajectories of spontaneous activity in developing CA1 and identify important roles of network bi-stability and synaptic input characteristics for hippocampal burstiness before eye opening.

    Evolution of C4 photosynthesis predicted by constraint-based modelling

    Mary-Ann Blätke, Andrea Bräutigam
    Constraint-based modelling predicts C4 photosynthesis evolves under resource limitation from an ancestral ground state of C3 photosynthesis and attributes divergent metabolic routes in extant C4 subtypes to light.

    A protein phosphatase network controls the temporal and spatial dynamics of differentiation commitment in human epidermis

    Ajay Mishra, Bénédicte Oulès ... Fiona M Watt
    A combination of transcriptomics, proteomics and modelling identifies a network of interacting protein phosphatases that act as a biological switch to move cells from the stem cell compartment to the differentiated compartment in cultured human epidermis.

    Complementary congruent and opposite neurons achieve concurrent multisensory integration and segregation

    Wen-Hao Zhang, He Wang ... Si Wu
    Opposite neurons in multisensory areas compute the cue disparity information essential for information segregation.
