    Achieving functional neuronal dendrite structure through sequential stochastic growth and retraction

    André Ferreira Castro et al.
    An optimal wire and function trade-off emerges from noisy growth and stochastic retraction during Drosophila class I ventral posterior dendritic arborisation (c1vpda) dendrite development.

    Collateral sensitivity associated with antibiotic resistance plasmids

    Cristina Herencias et al.
    Acquisition of antibiotic resistance plasmids induces collateral sensitivity to clinically relevant antibiotics in Escherichia coli, paving the way for targeted 'anti-plasmid' therapies able to preferentially eliminate plasmid-carrying bacteria.

    A transcriptomic taxonomy of Drosophila circadian neurons around the clock

    Dingbang Ma et al.
    Drosophila clock neurons manifest remarkable heterogeneity, which might be generally true and help explain why Drosophila has a sophisticated behavioral repertoire despite a tiny brain of about 100,000 neurons.

    The diversity and function of sourdough starter microbiomes

    Elizabeth A Landis et al.
    In the most comprehensive survey of sourdough starter biodiversity, this work identifies processes that control the diversity and function of sourdough microbiomes at a continental scale.

    Data-driven reduction of dendritic morphologies with preserved dendro-somatic responses

    Willem AM Wybo et al.
    A flexible and accurate methodology to fit reduced compartmental models to dendritic morphologies shows that models with very few compartments can capture many dendritic computations.

    Release probability increases towards distal dendrites boosting high-frequency signal transfer in the rodent hippocampus

    Dmitri A Rusakov et al.
    Excitatory synapses that occur further away from the postsynaptic cell soma exhibit greater neurotransmitter release probability, which appears to improve signal transfer fidelity for high-frequency afferent firing.

    Differential impact of BTK active site inhibitors on the conformational state of full-length BTK

    Raji E Joseph et al.
    The first-in-class kinase inhibitor, Ibrutinib, destabilizes its autoinhibited Bruton’s tyrosine kinase (BTK) target, and a remote resistance mutation causes global structural changes that activate BTK catalytic activity.

    Roles of the ClC chloride channel CLH-1 in food-associated salt chemotaxis behavior of C. elegans

    Chanhyun Park et al.
    A ClC chloride channel protein allows neurons to interpret both temporal resolution and intensity of sensory input, which thereby contributes to an experience-dependent navigation behavior.

    The half-life of the bone-derived hormone osteocalcin is regulated through O-glycosylation in mice, but not in humans

    Omar Al Rifai et al.
    In mice, but not in humans, the bone-derived hormone osteocalcin is O-glycosylated, a post-translational modification controlling its half-life in vivo.

    Ral GTPases promote breast cancer metastasis by controlling biogenesis and organ targeting of exosomes

    Shima Ghoroghi et al.
    A combination of animal models reveal how the molecular mechanisms of exosome secretion (RalA/B-dependent) are linked to their cargo content and their function in breast cancer pre-metastatic niche formation.
