    TRF1 averts chromatin remodelling, recombination and replication dependent-break induced replication at mouse telomeres

    Rosa Maria Porreca, Emilia Herrera-Moyano ... Jean-Baptiste Vannier
    TRF1 suppresses replication fork stalling, which triggers break induced replication at telomeres associated with DNA damage response, alteration in the telomere chromatin environment, and re-localisation of telomeres to PML bodies.

    Perception in autism does not adhere to Weber’s law

    Bat-Sheva Hadad, Sivan Schwartz
    Perception in autism is sensitive to absolute rather than to relative metrics of the environment, encoding changes in the environment without calibrating the changes relative to reference stimulation.

    Associations of four biological age markers with child development: A multi-omic analysis in the European HELIX cohort

    Oliver Robinson, ChungHo E Lau ... Martine Vrijheid
    Among European children, shorter telomere length and older DNA methylation age relative to chronological age were associated with poorer behaviors, while older age, as predicted by a novel immunometabolic clock relative to chronological age, was associated with greater cognitive maturity.

    Evolutionary routes to biochemical innovation revealed by integrative analysis of a plant-defense related specialized metabolic pathway

    Gaurav D Moghe, Bryan J Leong ... Robert L Last
    Integrative analysis of a specialized metabolic pathway across multiple non-model species illustrates mechanisms of emergence of chemical novelty in plant metabolism.

    Specific depletion of the motor protein KIF5B leads to deficits in dendritic transport, synaptic plasticity and memory

    Junjun Zhao, Albert Hiu Ka Fok ... Kwok-On Lai
    Two homologous kinesin motors, KIF5A and KIF5B, have distinct functions in dendritic spine morphogenesis, and KIF5B plays a role in synaptic plasticity and memory.

    Reinforcement biases subsequent perceptual decisions when confidence is low, a widespread behavioral phenomenon

    Armin Lak, Emily Hueske ... Adam Kepecs
    Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.

    Deep learning-based feature extraction for prediction and interpretation of sharp-wave ripples in the rodent hippocampus

    Andrea Navas-Olive, Rodrigo Amaducci ... Liset M de la Prida
    A new method is described to identify sharp-wave ripples from the rodent hippocampus with deep learning techniques, which may help to identify and characterize previously undetected physiological events.

    Parallel processing in speech perception with local and global representations of linguistic context

    Christian Brodbeck, Shohini Bhattasali ... Ellen Lau
    Speech processing engages multiple predictive models, using sublexical, word- and sentence contexts in parallel to anticipate upcoming phonemes.

    Site-directed MT1-MMP trafficking and surface insertion regulate AChR clustering and remodeling at developing NMJs

    Zora Chui-Kuen Chan, Hiu-Lam Rachel Kwan ... Chi Wai Lee
    Postsynaptic MT1-MMP serves as a molecular switch to synaptogenesis by clearing the surrounding ECM environment that allows effective deposition of nerve-derived synaptogenic factors to induce postsynaptic differentiation at developing NMJs.

    Evolution of a plant gene cluster in Solanaceae and emergence of metabolic diversity

    Pengxiang Fan, Peipei Wang ... Robert L Last
    A nightshade family gene cluster creates phenotypic novelty in trichome defensive metabolites via evolution of lipid metabolic enzymes.
