    Thermal fluctuations of immature SOD1 lead to separate folding and misfolding pathways

    Ashok Sekhar, Jessica AO Rumfeldt ... Lewis E Kay
    Solution NMR spectroscopy reveals the energy landscape of immature Cu, Zn-superoxide dismutase and leads to atomic resolution structural models of transiently populated non-native oligomers.

    Discovery of runs-of-homozygosity diplotype clusters and their associations with diseases in UK Biobank

    Ardalan Naseri, Degui Zhi, Shaojie Zhang
    ROH-DICE is an efficient method for detecting ROH clusters in biobank data, enabling the study of population history of large cohorts, and providing a new genome-wide association analysis approach for finding disease-causing loci with multi-marker recessive effects.

    DNA methylation and gene expression changes derived from assisted reproductive technologies can be decreased by reproductive fluids

    Sebastian Canovas, Elena Ivanova ... Pilar Coy
    Reproductive fluids help the correct establishment of some epigenetic marks and gene expression in preimplantation pig embryos.

    Hierarchical temporal prediction captures motion processing along the visual pathway

    Yosef Singer, Luke Taylor ... Nicol S Harper
    Neural network modeling shows that hierarchical application of the simple computational principle of predicting future sensory input from its past can capture features of visual motion processing from the retina to the visual cortex.

    Adaptive chunking improves effective working memory capacity in a prefrontal cortex and basal ganglia circuit

    Aneri Soni, Michael J Frank
    This frontostriatal neural network model links the source of working memory capacity limitations to challenges in learning resource management, and mitigates this challenge by learning a 'chunking' strategy.

    Two de novo GluN2B mutations affect multiple NMDAR-functions and instigate severe pediatric encephalopathy

    Shai Kellner, Abeer Abbasi ... Shai Berlin
    Two novel mutations in the GRIN2B gene reduce glutamate affinity by >1000-fold, reduce the receptors proton-sensitivity, and exert a dominant-negative effect over receptors in neurons.

    Expansion microscopy of C. elegans

    Chih-Chieh (Jay) Yu, Nicholas C Barry ... Edward S Boyden
    Fixed, intact animals of C. elegans can be physically expanded with high isotropy, to enable super-resolved imaging of general proteins and nucleic acids throughout the organism, on conventional microscopes.

    Disrupting the ciliary gradient of active Arl3 affects rod photoreceptor nuclear migration

    Amanda M Travis, Samiya Manocha ... Jillian N Pearring
    Dominant mutations in Arl3, linked to inherited retinal dystrophy, disrupt the active Arl3-GTP ciliary gradient and cause a defect in rod photoreceptor nuclear migration that can be rescued by elevating ciliary Arl3 activity or reducing aberrant non-ciliary Arl3 activity.

    The amyloid precursor protein is a conserved Wnt receptor

    Tengyuan Liu, Tingting Zhang ... Bassem A Hassan
    The amyloid precursor protein known for its role in causing familial Alzheimer's disease directly interacts with secreted proteins, called Wnts, known for their key roles in brain development and homeostasis, suggesting the two processes may be directly linked.

    Gdf3 is required for robust Nodal signaling during germ layer formation and left-right patterning

    Jose L Pelliccia, Granton A Jindal, Rebecca D Burdine
    Genetic analyses demonstrate that Gdf3/Vg1 is a maternal effect gene required for robust Nodal signaling during different phases of embryogenesis including germ-layer formation, Kupffer's vesicle morphogenesis, and left-right patterning.
