    How microscopic epistasis and clonal interference shape the fitness trajectory in a spin glass model of microbial long-term evolution

    Nicholas M Boffi, Yipei Guo ... Ariel Amir
    High-resolution simulations of evolving microbial populations reveal that microscopic epistasis slows the rate of adaptation, while clonal interference can either speed it up or leave it fixed.

    β-catenin inhibition disrupts the homeostasis of osteogenic/adipogenic differentiation leading to the development of glucocorticoid-induced osteonecrosis of the femoral head

    Chenjie Xia, Huihui Xu ... Hongting Jin
    Deletion of β-catenin in Col2+ progenitor cells shifts their commitment from osteoblasts to adipocytes, leading to a full spectrum of disease phenotype of glucocorticoid-induced osteonecrosis of the femoral head in adult mice.

    Spatial–temporal order–disorder transition in angiogenic NOTCH signaling controls cell fate specification

    Tae-Yun Kang, Federico Bocci ... Andre Levchenko
    The transition from a restrictive patterning mechanism to one sensitive to a variety of environmental cues in NOTCH-mediated angiogenesis offers crucial insights into vascularization in damaged organs and cancer therapy.

    Disordered regions and folded modules in CAF-1 promote histone deposition in Schizosaccharomyces pombe

    Fouad Ouasti, Maxime Audin ... Francoise Ochsenbein
    Histone, PCNA, and DNA binding are essential for CAF-1 functions in preventing DNA damage during DNA replication in Schizosaccharomyces pombe, while its C-terminal domain specifies distinct cellular processes.

    Nucleosome conformation dictates the histone code

    Matthew R Marunde, Harrison A Fuchs ... Catherine A Musselman
    NMR spectroscopy, dCypher assays, and CUT&RUN demonstrate that occlusion of the histone tails in the nucleosome context alters histone PTM specificity for a tandem of reader domains.

    Organelle proteomic profiling reveals lysosomal heterogeneity in association with longevity

    Yong Yu, Shihong M Gao ... Meng C Wang
    First systemic lysosomal proteomes in association with longevity and tissue specificity in C. elegans uncover lysosomal heterogeneity across multiple scales and provide valuable resources for understanding how lysosomes modulate signal transduction, organelle communication, tissue physiology, and organism longevity.

    Altered hierarchical auditory predictive processing after lesions to the orbitofrontal cortex

    Olgerta Asko, Alejandro Omar Blenkmann ... Anne-Kristin Solbakk
    Orbitofrontal cortex lesions impact the neural correlates of detection of auditory regularity violation at two hierarchical levels of rule abstraction, providing a novel perspective on the role of the orbitofrontal cortex in auditory predictive processing.

    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.
