    Cell types and neuronal circuitry underlying female aggression in Drosophila

    Catherine E Schretter et al.
    A discrete group of interconnected neurons are shown to drive aggressive social interactions in Drosophila females and genetic tools to manipulate these neuronal cell types are provided.

    Evaluating distributional regression strategies for modelling self-reported sexual age-mixing

    Timothy M Wolock et al.
    Integrating the sinh-arcsinh distribution into a distributional regression framework allows us to produce precise, local estimates of sexual age-mixing, facilitating more accurate modelling of sexually transmitted disease dynamics.

    Layered roles of fruitless isoforms in specification and function of male aggression-promoting neurons in Drosophila

    Margot Wohl et al.
    Male-type aggressive and courtship behaviors of the fruit flies are differentially specified by two sex-determining genes, providing a substrate for the evolution to sculpt these two behaviors independently.

    Sleep deprivation suppresses aggression in Drosophila

    Matthew S Kayser et al.
    A single night of sleep deprivation suppresses fighting behaviors in male fruit flies, with consequent impairments in reproductive fitness.

    Cerebellar Purkinje cell activity modulates aggressive behavior

    Skyler L Jackman et al.
    Optogenetic control of Purkinje cells in the cerebellar vermis enables bidirectional control of aggression.

    P1 interneurons promote a persistent internal state that enhances inter-male aggression in Drosophila

    Eric D Hoopfer et al.
    A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.

    Urocortin-3 neurons in the mouse perifornical area promote infant-directed neglect and aggression

    Anita E Autry et al.
    Genetic and functional manipulations uncover urocortin-3-expressing neurons in the perifornical area of the hypothalamus as a dedicated circuit component for the expression of infant-directed neglect and aggression in mice.

    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.

    Dynamics of primitive streak regression controls the fate of neuromesodermal progenitors in the chicken embryo

    Charlene Guillot et al.
    Inverse gradients of cell ingression and division in the epiblast allow the bipotent progenitors in the anterior streak to become the main progenitors for posterior axis formation from the tail bud.

    Ingression-type cell migration drives vegetal endoderm internalisation in the Xenopus gastrula

    Jason WH Wen, Rudolf Winklbauer
    The cellular behaviours that underlie the internalization of the multilayered endoderm anlage in Xenopus laevis link the ancestral mode of vertebrate gastrulation to common, epithelial-based mechanisms of gastrulation in non-vertebrate animals.
