    Contractile acto-myosin network on nuclear envelope remnants positions human chromosomes for mitosis

    Alexander JR Booth et al.
    Live-cell imaging shows that the contractile acto-myosin network on the nuclear envelope remnant positions chromosomes in early mitosis to ensure efficient and correct interactions between chromosomes and the mitotic spindle.

    Anterior CNS expansion driven by brain transcription factors

    Jesús Rodriguez Curt et al.
    The expansion of the anterior Drosophila CNS is driven by increased progenitor generation and prolonged proliferation, mediated by brain-restricted genes and the PRC2.

    An explanation for origin unwinding in eukaryotes

    Lance D Langston, Michael E O'Donnell
    CMG helicase translocates with force while encircling duplex DNA, enabling two opposing CMG complexes at an origin to melt the duplex and switch to encircling separate single strands.

    Active information maintenance in working memory by a sensory cortex

    Xiaoxing Zhang et al.
    Delay-period activity of anterior piriform cortex is important for working memory tasks requiring active maintenance and encodes the maintained information.

    The microbiota protects from viral-induced neurologic damage through microglia-intrinsic TLR signaling

    D Garrett Brown et al.
    Immune stimulation from the microbiota prevents neurological damage associated with viral infection of the central nervous system.

    The transcription factor Hey and nuclear lamins specify and maintain cell identity

    Naama Flint Brodsly et al.
    Hey together with LaminC continuously supervise nuclear organisation and differentiated enterocyte identity, a regulation that is lost upon ageing, resulting in loss of gut homeostasis.

    Swimming eukaryotic microorganisms exhibit a universal speed distribution

    Maciej Lisicki et al.
    Analysis of published studies reveals that flagellates and ciliates separately exhibit log-normal distributions of swimming speeds, and rescaling by the mean speed of each collapses them to a universal relationship.

    Vasoactive intestinal peptide-expressing interneurons are impaired in a mouse model of Dravet syndrome

    Kevin M Goff, Ethan M Goldberg
    Vasoactive intestinal peptide-expressing GABAergic interneurons in cerebral cortex express the sodium channel subunit Nav1.1, and a defined subset of VIP interneurons are dysfunctional in a mouse model of Dravet syndrome.

    The genomes of polyextremophilic cyanidiales contain 1% horizontally transferred genes with diverse adaptive functions

    Alessandro W Rossoni et al.
    Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.

    Sonic hedgehog signaling in astrocytes mediates cell type-specific synaptic organization

    Steven A Hill et al.
    Astrocytes modulate synaptic remodeling of developing circuits in a cell type-specific manner, with long lasting deficits in synaptic plasticity.
