    Role of direct and indirect social and spatial ties in the diffusion of HIV and HCV among people who inject drugs: a cross-sectional community-based network analysis in New Delhi, India

    Steven J Clipman et al.
    Beyond well-recognized individual-level risk factors, HIV and hepatitis C transmission among people who inject drugs are further impacted by social and spatial network composition, and spaces in particular may represent efficient means for disseminating interventions that diffuse through the network.

    Sequential phenotypic constraints on social information use in wild baboons

    Alecia J Carter et al.
    Social information is a process encompassing information acquisition, application and exploitation that is constrained by an individual’s social, behavioural and demographic phenotype.

    Differential requirements for cyclase-associated protein (CAP) in actin-dependent processes of Toxoplasma gondii

    Alex Hunt et al.
    Partially overlapping functions of a limited subset of actin binding proteins allow the parasite Toxoplasma gondii to achieve actin regulation required for complex cellular processes.

    An afferent white matter pathway from the pulvinar to the amygdala facilitates fear recognition

    Jessica McFadyen et al.
    A subcortical white matter connection from the pulvinar to the amygdala predicts how well we recognise fearful faces and the strength of feed-forward neural connectivity.

    Distinct mechanisms mediate speed-accuracy adjustments in cortico-subthalamic networks

    Damian M Herz et al.
    Dynamic changes in activity and connectivity of the human subthalamic nucleus reflect whether a decision will be made in haste or with caution.

    Analysis of ultrasonic vocalizations from mice using computer vision and machine learning

    Antonio HO Fonseca et al.
    An open-source tool based on computational vision and machine learning shows high accuracy and sensitivity in the analysis of ultrasonic vocalizations.

    Asymmetric random walks reveal that the chemotaxis network modulates flagellar rotational bias in Helicobacter pylori

    Jyot D Antani et al.
    Asymmetric forward and backward swimming speeds reveal that the rotational bias, and not reversal frequencies, is an appropriate measure of chemotaxis signaling in Helicobacter pylori..

    Spatially compartmentalized phase regulation of a Ca2+-cAMP-PKA oscillatory circuit

    Brian Tenner et al.
    Nanodomain clustering of cAMP effectors represents a novel mechanism of cAMP compartmentation within an oscillatory signaling circuit.

    Amyloid and tau accumulate across distinct spatial networks and are differentially associated with brain connectivity

    Joana B Pereira et al.
    The amyloid patterns overlap with the default-mode network, whereas the tau patterns overlap with distinct functional networks and are associated with a loss of anatomical connectivity and multiple cognitive functions.

    Arp2/3 complex-driven spatial patterning of the BCR enhances immune synapse formation, BCR signaling and B cell activation

    Madison Bolger-Munro et al.
    Arp2/3 complex-mediated actin polymerization shapes how B lymphocytes probe the surface of antigen-presenting cells, promotes coalescence of B cell receptor (BCR) microclusters, amplifies BCR signaling, and enhances B cell activation.
