    Purinergic signaling in cochlear supporting cells reduces hair cell excitability by increasing the extracellular space

    Travis A Babola et al.
    Supporting cells in the cochlea change their shape in response to purinergic receptor activation, which influences hair cell excitability by altering potassium redistribution in the extracellular space.

    Generic injuries are sufficient to induce ectopic Wnt organizers in Hydra

    Jack F Cazet et al.
    Injuries activate the oral identity-specifying canonical Wnt signaling pathway in Hydra, which can trigger head regeneration in permissive tissue contexts created by the absence of pre-existing organizers.

    Drift and termination of spiral waves in optogenetically modified cardiac tissue at sub-threshold illumination

    Sayedeh Hussaini et al.
    Excitability gradients in heart tissue, imposed by structured sub-threshold optogenetic stimulation, induce drift and termination of spiral waves, thus providing an explanation for successful optogenetic defibrillation in small animal hearts.

    Prickle isoforms determine handedness of helical morphogenesis

    Bomsoo Cho et al.
    The Pkpk and Pksple isoforms of the Prickle protein determine right- or left-handed bristle morphogenesis by coupling Frizzled/Vang signaling to the Fat/Dachsous PCP directional signal in opposite directions.

    All-atom molecular dynamics of the HBV capsid reveals insights into biological function and cryo-EM resolution limits

    Jodi A Hadden et al.
    All-atom molecular dynamics of the HBV capsid supports a role for structural asymmetry in biological function, reveals the potential for triangular pores to mediate cellular signaling, and indicates that capsid flexibility may limit resolution attainable by cryo-EM.

    Mechanisms of opening and closing of the bacterial replicative helicase

    Jillian Chase et al.
    Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.

    A comparative transcriptomic analysis of replicating and dormant liver stages of the relapsing malaria parasite Plasmodium cynomolgi

    Annemarie Voorberg-van der Wel et al.
    This comprehensive transcriptomic resource of dormant and replicating malaria liver parasites highlights the dearth of pathways that operate in the hypnozoites and the need to investigate druggability (i.e. selectivity and safety) of core pathways in malaria parasites.

    A picorna-like virus suppresses the N-end rule pathway to inhibit apoptosis

    Zhaowei Wang et al.
    A picorna-like virus promotes the accumulation of caspase-cleaved drosophila inhibitor of apoptosis 1 by inducing the degradation of NTAN1, a key N-end rule degradation pathway component, leading to apoptosis inhibition and viral replication enhancement.

    ErbB4 deletion in noradrenergic neurons in the locus coeruleus induces mania-like behavior via elevated catecholamines

    Shu-Xia Cao et al.
    Behavioral and molecular mechanistic studies elaborate the important role of ErbB4 in noradrenergic neurons associated with mania pathogenesis.

    Stimulus background influences phase invariant coding by correlated neural activity

    Michael G Metzen, Maurice J Chacron
    Building on previous work (Metzen et al., 2016), a combination of neurophysiological and behavioral approaches reveals that changes in the background strongly impacts invariant coding and perception of behaviourally relevant signals.
