    A Brownian ratchet model for DNA loop extrusion by the cohesin complex

    Torahiko L Higashi et al.
    A structure-based model of the chromosomal cohesin complex, accompanied by molecular-mechanistic simulations, explains cohesin's key role in topologically entrapping DNA, as well as its ability to alternatively extrude DNA loops.

    Mapping brain-behavior space relationships along the psychosis spectrum

    Jie Lisa Ji et al.
    A data-reduced neuro-behavioral geometry in psychosis spectrum disorders mapped symptoms stably on to distinct functional brain regions and offers a framework for informing personalized treatment selection decisions.

    Relationship between changing malaria burden and low birth weight in sub-Saharan Africa: A difference-in-differences study via a pair-of-pairs approach

    Siyu Heng et al.
    A novel pair-of-pairs matching approach finds that community-level reductions in malaria burden can potentially substantially reduce the low birth weight rate in sub-Saharan Africa, particularly among firstborns.

    The genetic organization of longitudinal subcortical volumetric change is stable throughout the lifespan

    Anders Martin Fjell et al.
    Volumetric lifespan change in subcortical structures follows fundamental principles of brain development, lifespan continuity, genetic organization, and age-invariant relationships to cognition.

    Connectional asymmetry of the inferior parietal lobule shapes hemispheric specialization in humans, chimpanzees, and rhesus macaques

    Luqi Cheng et al.
    Humans showed the most widespread asymmetric connectivity between the inferior parietal lobule subregions and the rest of the brain compared to macaques and chimpanzees, which shapes hemispheric specialization in primates.

    Thalamus and claustrum control parallel layer 1 circuits in retrosplenial cortex

    Ellen KW Brennan et al.
    Parallel input streams to layer 1 identify a computationally distinct principal neuronal subtype ideally positioned to support spatial orientation computations in the granular retrosplenial cortex.

    The trajectory of cortical GABA across the lifespan, an individual participant data meta-analysis of edited MRS studies

    Eric C Porges et al.
    Individual participant data meta-analysis reveals the estimated lifespan trajectory of cortical GABA, characterized by an early rapid increase, followed by a period of stability during early adulthood, and a gradual decrease.

    Modeling the impact of racial and ethnic disparities on COVID-19 epidemic dynamics

    Kevin C Ma et al.
    Racial and ethnic disparities in SARS-CoV-2 infection rates can impact overall epidemic dynamics and herd immunity, underscoring the need to develop socially informed transmission models that account for population variability.

    Organ geometry channels reproductive cell fate in the Arabidopsis ovule primordium

    Elvira Hernandez-Lagana et al.
    In the Arabidopsis ovule primordium, germinal fate plasticity is coupled to the morphogenetic processes shaping the organ.

    Quantitative mapping of human hair greying and reversal in relation to life stress

    Ayelet M Rosenberg et al.
    A method to profile hair pigmentation patterns establishes a new approach for psychobiological studies and links metabolic changes to greying in humans.
