    A Myt1 family transcription factor defines neuronal fate by repressing non-neuronal genes

    Joo Lee et al.
    First comprehensive genetic analysis of a Myt1 family protein reveals that neurogenesis requires direct repression of non-neuronal identities by the Myt1 family protein through MuvB co-repressor complex.

    Blood flow guides sequential support of neutrophil arrest and diapedesis by PILR-β1 and PILR-α

    Yu-Tung Li et al.
    Blood flow-driven shear forces guide the sequential signaling of two antagonistic paired receptors, a critical bi-facet step that first supports leukocyte docking, then initiates transmigration through endothelium.

    Mapping sequence structure in the human lateral entorhinal cortex

    Jacob LS Bellmund et al.
    Mnemonic representations in the human anterior-lateral entorhinal cortex change through learning to reflect an experienced temporal event structure and holistic temporal maps relate to memory recall.

    Natural selection and repeated patterns of molecular evolution following allopatric divergence

    Yibo Dong et al.
    The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.
