    A Fyn biosensor reveals pulsatile, spatially localized kinase activity and signaling crosstalk in live mammalian cells

    Ananya Mukherjee et al.
    Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

    E. coli TraR allosterically regulates transcription initiation by altering RNA polymerase conformation

    James Chen et al.
    Cryo-electron microscopy structures, combined with biochemical experiments, show how the E. coli F element-encoded TraR protein regulates transcription initiation by altering RNA polymerase conformation and conformational heterogeneity.

    Ciliary Rab28 and the BBSome negatively regulate extracellular vesicle shedding

    Jyothi S Akella et al.
    The RAB-28 GTPase regulates ciliary extracellular vesicle shedding, which may be important for neuron-glia communication.

    Ecdysone steroid hormone remote controls intestinal stem cell fate decisions via the PPARγ-homolog Eip75B in Drosophila

    Lisa Zipper et al.
    A systemic hormone controls progenitor fate decisions independent of local fate determining pathways in the adult intestinal stem cell niche of Drosophila melanogaster..

    Male-predominant galanin mediates androgen-dependent aggressive chases in medaka

    Junpei Yamashita et al.
    In medaka fish, galanin-expressing neurons in the medial preoptic area occur nearly exclusively in males and mediate androgen-dependent male–male aggressive chases.

    Growth cone-localized microtubule organizing center establishes microtubule orientation in dendrites

    Xing Liang et al.
    In Caenorhabditis elegans, dendrites establish their unique microtubule polarity by localizing an organizing center behind the growing tip.

    Aberrant sorting of hippocampal complex pyramidal cells in type I lissencephaly alters topological innervation

    James A D'Amour et al.
    The loss of lamination in mammalian brain structures under cellular heterotopia carries with it non-uniform ramifications for the various components of the canonical CA1 microcircuitry.

    Quantitative analysis of how Myc controls T cell proteomes and metabolic pathways during T cell activation

    Julia M Marchingo et al.
    Myc-dependent induction of amino acid transporter expression in response to T cell receptor activation is essential to enable T cell proteome remodelling upon immune activation.

    Symptom evolution following the emergence of maize streak virus

    Adérito L Monjane et al.
    Phylogenetic analyses demonstrate an evolutionary trade-off between the amount of harm inflicted by a broad host-range virus and how effectively the virus positions itself within plants to enable onward transmission.

    Actin assembly ruptures the nuclear envelope by prying the lamina away from nuclear pores and nuclear membranes in starfish oocytes

    Natalia Wesolowska et al.
    Combined light and electron microscopy reveals a new function for Arp2/3-mediated actin assembly in nuclear envelope rupture, which leads to a separation of nuclear membranes and pores from the lamina.
