    A multilayer circuit architecture for the generation of distinct locomotor behaviors in Drosophila

    Aref Arzan Zarin et al.
    Generation of a premotor/motor neuron comprehensive TEM reconstruction, functional optogenetics, and recurrent network modeling reveals different phase relationships among a subset of Drosophila motor neurons in forward versus backward locomotion.

    Coordination of humoral immune factors dictates compatibility between Schistosoma mansoni and Biomphalaria glabrata

    Hongyu Li et al.
    A coordinated humoral immune response that includes recognition, effector and cytotoxic factors engages the cell-mediated immune response to defend a snail against infection by schistosome parasites.

    Deep sampling of Hawaiian Caenorhabditis elegans reveals high genetic diversity and admixture with global populations

    Tim A Crombie et al.
    Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.

    Efa6 protects axons and regulates their growth and branching by inhibiting microtubule polymerisation at the cortex

    Yue Qu et al.
    The cortical collapse factor Efa6 limits axon growth and branching and maintains axonal microtubule bundle integrity by inhibiting microtubule polymerisation at the cell cortex.

    Optimal searching behaviour generated intrinsically by the central pattern generator for locomotion

    David W Sims et al.
    The nervous system circuitry that controls locomotion has evolved to intrinsically generate an optimal search pattern for resources.

    ON selectivity in the Drosophila visual system is a multisynaptic process involving both glutamatergic and GABAergic inhibition

    Sebastian Molina-Obando et al.
    A fundamental visual computation, the establishment of ON selectivity, is established across distributed circuits, allowing for more robust and flexible coding than suggested by core circuit motifs.

    A single clonal lineage of transmissible cancer identified in two marine mussel species in South America and Europe

    Marisa A Yonemitsu et al.
    A transmissible cancer that arose in a marine mussel spread from a single animal to become a global pathogen affecting two other mussel species in both Europe and South America.

    Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment

    Kate A Rawlinson et al.
    A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.
