    A novel DNA primase-helicase pair encoded by SCCmec elements

    Aleksandra Bebel et al.
    SCCmec genomic islands encode a novel primase-helicase pair in which priming ability is conferred upon an A-family DNA polymerase domain by a novel protein cofactor.

    Structural insights into mRNA reading frame regulation by tRNA modification and slippery codon–anticodon pairing

    Eric D Hoffer et al.
    Chemical modifications near the tRNA anticodon and specific mRNA–tRNA pairs combine to control the ribosomal three-nucleotide mRNA reading frame, essential for the sequential addition of amino acids into polypeptide chains.

    A large accessory protein interactome is rewired across environments

    Zhimin Liu et al.
    A massively multiplexed multi-condition screen shows that protein interactomes are larger than previously thought and contain highly dynamic regions that reorganize to drive or respond to cellular changes.

    Developmental, cellular, and behavioral phenotypes in a mouse model of congenital hypoplasia of the dentate gyrus

    Amir Rattner et al.
    A mouse mutant in which nearly all dentate gyrus granule cells fail to develop provides a new window on the role of the dentate gyrus in spatial learning and memory.

    Artemisinin exposure at the ring or trophozoite stage impacts Plasmodium falciparum sexual conversion differently

    Harvie P Portugaliza et al.
    Treatment of malaria parasites with the frontline antimalarial drug artemisinin can increase the proportion of parasites that convert into transmission forms.

    A broadly neutralizing macaque monoclonal antibody against the HIV-1 V3-Glycan patch

    Zijun Wang et al.
    Rhesus macaques can develop broadly neutralizing antibodies (bNAbs) against the V3-glycan patch of Env that resembles human V3/N332 bNABs.

    Rapid purification and metabolomic profiling of synaptic vesicles from mammalian brain

    Lynne Chantranupong et al.
    Extensive mass spectrometry-based profiling of polar metabolites within synaptic vesicles that are rapidly isolated either from cultured mouse neurons or directly from mouse brains reveals their neurotransmitter composition.

    Neuronal octopamine signaling regulates mating-induced germline stem cell increase in female Drosophila melanogaster

    Yuto Yoshinari et al.
    Genetic analyses using the fruit fly illustrate how neuronal system couples germline stem cell increase to an external cue, which is mating, through stem cell niche signaling.

    Unbiased homeologous recombination during pneumococcal transformation allows for multiple chromosomal integration events

    Jun Kurushima et al.
    DNA uptake and recombination in pneumococcus are highly efficient and independent of the cell-cycle or genetic location of the transformed allele, but limited to maximally 50% of the population.

    Deciphering the regulatory genome of Escherichia coli, one hundred promoters at a time

    William T Ireland et al.
    A combination of massively parallel reporter assays and mass spectrometry uncovers the regulation of previously unexplored promoters across the Escherichia coli genome.
