    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, Shruti H Mehta ... Sunil S Solomon
    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, Miquel Torrents Ticó, Guy Cowlishaw
    Social information is a process encompassing information acquisition, application and exploitation that is constrained by an individual’s social, behavioural and demographic phenotype.

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

    Joana B Pereira, Rik Ossenkoppele ... Oskar Hansson
    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.

    Network structure of brain atrophy in de novo Parkinson's disease

    Yashar Zeighami, Miguel Ulla ... Alain Dagher
    The pattern of atrophy in Parkinson's disease is consistent with the disease spreading via intrinsic brain networks.

    High-throughput mathematical analysis identifies Turing networks for patterning with equally diffusing signals

    Luciano Marcon, Xavier Diego ... Patrick Müller
    Realistic reaction-diffusion signaling networks that include cell-autonomous factors can robustly form self-organizing spatial patterns for any combination of diffusion coefficients without requiring differential diffusivity.

    Biological condensates form percolated networks with molecular motion properties distinctly different from dilute solutions

    Zeyu Shen, Bowen Jia ... Mingjie Zhang
    Molecules in the condensed phase of biological condensates convert between transiently confined states and mobile states by forming dynamic percolated networks.

    Social learning mechanisms shape transmission pathways through replicate local social networks of wild birds

    Kristina B Beck, Ben C Sheldon, Josh A Firth
    Social connectivity increases an individual’s likelihood of behavioural adoption if the learning rule depends on the extent of social connections to informed others, but is unrelated when learning depends on the ratio of connections to informed versus uninformed others.

    Deciphering anomalous heterogeneous intracellular transport with neural networks

    Daniel Han, Nickolay Korabel ... Thomas A Waigh
    Direct estimation of the Hurst exponent shows that endosomes and lysosomes reside in regimes of persistent and anti-persistent motion with heavy-tailed residence time distributions and motion correlated with endocytic function.

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

    Antonio HO Fonseca, Gustavo M Santana ... Marcelo O Dietrich
    An open-source tool based on computational vision and machine learning shows high accuracy and sensitivity in the analysis of ultrasonic vocalizations.
