    Unraveling the developmental dynamic of visual exploration of social interactions in autism

    Nada Kojovic, Sezen Cekic ... Marie Schaer
    Children with ASD showed a significant divergence in gaze patterns compared to typically developing children, intensifying over early childhood, with implications for developmental and adaptive functioning.

    A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

    Renat N Khaliullin, Rebecca A Green ... Karen Oegema
    Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

    Radially patterned cell behaviours during tube budding from an epithelium

    Yara E Sanchez-Corrales, Guy B Blanchard, Katja Röper
    Quantitative analysis in quasi-3D reveals apically driven cell behaviours that are closely coordinated across the tissue to allow ordered tube invagination through a focal point.

    HP1α is a chromatin crosslinker that controls nuclear and mitotic chromosome mechanics

    Amy R Strom, Ronald J Biggs ... Andrew D Stephens
    Micromanipulation experiments demonstrate that HP1α strengthens interphase and mitotic chromosome mechanics and maintains nuclear shape by chromatin crosslinking, separate from histone methylation.

    A new view of transcriptome complexity and regulation through the lens of local splicing variations

    Jorge Vaquero-Garcia, Alejandro Barrera ... Yoseph Barash
    New methods reveal that complex local splicing variations are more prevalent in animals than previously appreciated, and demonstrate that local splicing variations are relevant for studies of development, gene regulation and neurodegenerative diseases.

    Reorganization of postmitotic neuronal chromatin accessibility for maturation of serotonergic identity

    Xinrui L Zhang, William C Spencer ... Evan S Deneris
    Terminal selectors reorganize postmitotic neuronal chromatin to select cis-regulatory elements during 5-HT neuron maturation.

    Widespread correlation patterns of fMRI signal across visual cortex reflect eccentricity organization

    Michael J Arcaro, Christopher J Honey ... Uri Hasson
    Functional coupling between visual areas reflects supra-areal eccentricity organization distinct from overlapping receptive field connectivity during both rest conditions and naturalistic movie viewing.

    Host-pathogen genetic interactions underlie tuberculosis susceptibility in genetically diverse mice

    Clare M Smith, Richard E Baker ... Christopher M Sassetti
    A novel dual genome approach that combines genetically diverse mice and a library of bacterial mutants to define the genome-wide host pathogen interactions that drive distinct outcomes to tuberculosis.

    Stress responsive miR-31 is a major modulator of mouse intestinal stem cells during regeneration and tumorigenesis

    Yuhua Tian, Xianghui Ma ... Zhengquan Yu
    miR-31 drives proliferation of intestinal stem cells, and protects intestinal stem cells against apoptosis both during homeostasis and regeneration in response to ionizing radiation injury, and promotes intestinal tumorigenesis through regulation of multiple signaling pathways.

    Glycolytic preconditioning in astrocytes mitigates trauma-induced neurodegeneration

    Rene Solano Fonseca, Patrick Metang ... Peter M Douglas
    Promoting a Warburg-like shift in astrocytic metabolism through reduced mitochondrial electron transport accommodates the energetic burden caused by brain trauma without overwhelming cellular respiration and redox to salvage dopaminergic neurons.
