    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    A single-cell transcriptomic and anatomic atlas of mouse dorsal raphe Pet1 neurons

    Benjamin W Okaty et al.
    Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.

    Acute disruption of the synaptic vesicle membrane protein synaptotagmin 1 using knockoff in mouse hippocampal neurons

    Jason D Vevea, Edwin R Chapman
    Knockoff is a tool for researchers who wish to acutely disrupt a membrane protein.

    Control of brown adipose tissue adaptation to nutrient stress by the activin receptor ALK7

    Patricia Marmol et al.
    The activin receptor ALK7 regulates the adaptation of brown adipose tissue to nutrient availability by preventing over-activation of signaling pathways induced by fasting, allowing appropriate response to cold exposure.

    In vivo assessment of the neural substrate linked with vocal imitation accuracy

    Julie Hamaide et al.
    Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.

    Dominant Vibrio cholerae phage exhibits lysis inhibition sensitive to disruption by a defensive phage satellite

    Stephanie G Hays, Kimberley D Seed
    Genetic and molecular analyses identify and characterize an evolutionary battle over lysis timing wherein a bacteriophage delays lysis through lysis inhibition while a defensive phage satellite accelerates lysis.

    Cross-species cortical alignment identifies different types of anatomical reorganization in the primate temporal lobe

    Nicole Eichert et al.
    Cross-species alignment based on cortical myelin content can dissociate cortical expansion and relocation from changes in connectivity profiles in the temporal lobe of higher primates.

    Visually-updated hand state estimates modulate the proprioceptive reflex independently of motor task requirements

    Sho Ito, Hiroaki Gomi
    Distortion and elimination of limb visual feedback affects low-level stretch reflex control, indicating the involvement of a high-level and multimodal representation of the limb state in orchestrating hierarchical sensorimotor control.

    The transpeptidase PBP2 governs initial localization and activity of the major cell-wall synthesis machinery in E. coli

    Gizem Özbaykal et al.
    For initiation of cell-wall insertion, the cross-linking enzyme PBP2 stably binds to a component of the cell envelope that is different from MreB filaments.

    Structural model for differential cap maturation at growing microtubule ends

    Juan Estévez-Gallego et al.
    The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.
