    Rapid decline of bacterial drug-resistance in an antibiotic-free environment through phenotypic reversion

    Anett Dunai et al.
    Drug-resistance declines in the laboratory in an antibiotic stress-free environment, indicating that restricting antimicrobial usage in the clinics could be a useful policy.

    Structural and functional insights into the bona fide catalytic state of Streptococcus pyogenes Cas9 HNH nuclease domain

    Zhicheng Zuo et al.
    The catalytic activation of the Cas9 HNH domain involves a unique conformational change in the ββα-metal motif that is collectively driven by the interactions with the metal ions and DNA.

    Spatiotemporal control of mitotic exit during anaphase by an aurora B-Cdk1 crosstalk

    Olga Afonso et al.
    Quantitative live-cell microscopy and molecular perturbations in Drosophila and human cells reveal a crosstalk between molecular 'rulers' (Aurora B) and 'clocks' (Cdk1) that coordinates mitotic exit in space and time.

    A single K+-binding site in the crystal structure of the gastric proton pump

    Kenta Yamamoto et al.
    Crystal structures provide structural rationales for the transport stoichiometry of the gastric proton pump, which suffices the energy requirement for the generation of a million-fold proton gradient across the membrane.

    Activity dynamics of amygdala GABAergic neurons during cataplexy of narcolepsy

    Ying Sun et al.
    Deep brain calcium imaging reveals the abnormal neuronal activity patterns of the amygdala GABAergic neurons in an animal model of human sleep disorder narcolepsy.

    B cell receptor and Toll-like receptor signaling coordinate to control distinct B-1 responses to both self and the microbiota

    Lieselotte SM Kreuk et al.
    Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.

    A conserved Mcm4 motif is required for Mcm2-7 double-hexamer formation and origin DNA unwinding

    Kanokwan Champasa et al.
    Analysis of an essential motif in Mcm4 provides insights into replicative helicase double-hexamer formation and the first step requiring this intermediate during replication initiation.

    Spinal V2b neurons reveal a role for ipsilateral inhibition in speed control

    Rebecca A Callahan et al.
    Two anatomically and genetically distinct subtypes of spinal V2b neurons provide inhibition onto motor circuits and serve as a brake on locomotor speed.

    Self-organised segregation of bacterial chromosomal origins

    Andreas Hofmann et al.
    The self-organising condensin MukBEF positions chromosomal origins in Escherichia coli..
