    More homogeneous capillary flow and oxygenation in deeper cortical layers correlate with increased oxygen extraction

    Baoqiang Li et al.
    Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

    Neuronal integration in the adult mouse olfactory bulb is a non-selective addition process

    Jean-Claude Platel et al.
    Adult neurogenesis in the olfactory bulb is not a turnover system but represents a lifelong neuronal addition mechanism.

    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.
