    A contractile injection system stimulates tubeworm metamorphosis by translocating a proteinaceous effector

    Charles F Ericson et al.
    Bacteria produce a syringe-like structure, loaded with a single protein within the lumen of its needle-like tube, that is sufficient for stimulating animal metamorphosis.

    Ancient role of sulfakinin/cholecystokinin-type signalling in inhibitory regulation of feeding processes revealed in an echinoderm

    Ana B Tinoco et al.
    Starfish feed by everting their stomach out of their mouth over prey and, interestingly, this unusual feeding mechanism is inhibited by substances similar to hormones that regulate feeding in humans.

    Vascular dimorphism ensured by regulated proteoglycan dynamics favors rapid umbilical artery closure at birth

    Sumeda Nandadasa et al.
    Morphologic, molecular, biomechanical and computational analyses show that the specialized extracellular matrix architecture of the umbilical artery contributes to its rapid closure at birth and regulates smooth muscle cell differentiation.

    Cortical flow aligns actin filaments to form a furrow

    Anne-Cecile Reymann et al.
    Compressing the actomyosin network by cortical flow causes filaments to align and form a constricting ring.

    Two consecutive microtubule-based epithelial seaming events mediate dorsal closure in the scuttle fly Megaselia abdita

    Juan Jose Fraire-Zamora et al.
    Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

    Glucose inhibits cardiac muscle maturation through nucleotide biosynthesis

    Haruko Nakano et al.
    During cardiogenesis, the major role of glucose is not the catabolic extraction of energy but the anabolic biosynthesis of nucleotides.

    An hourglass circuit motif transforms a motor program via subcellularly localized muscle calcium signaling and contraction

    Steven R Sando et al.
    By driving the localized contraction of subcellular muscle regions, a single motor neuron reverses the flow of material in the Caenorhabditis elegans pharynx, a neuromuscular pump, converting feeding into spitting.

    The corticospinal tract primarily modulates sensory inputs in the mouse lumbar cord

    Yunuen Moreno-Lopez et al.
    While the corticospinal tract is often considered exclusively as a motor path, a combination of intersectional viral strategy and in vivo electrophysiology reveals that, in the mouse lumbar cord, its main role is the modulation of sensory inputs.

    Vertex sliding drives intercalation by radial coupling of adhesion and actomyosin networks during Drosophila germband extension

    Timothy E Vanderleest et al.
    Tricellular vertices possess sliding behaviors that harness radial forces and drive cell shape changes and intercalation in an epithelial tissue.

    Cell-intrinsic and -extrinsic mechanisms promote cell-type-specific cytokinetic diversity

    Tim Davies et al.
    Functional molecular analysis of cytokinesis in Caenorhabditis elegans four-cell embryos reveals cell-type-specific variation in the fundamental dependence on a robust f-actin cytoskeleton for successful cell division, mediated by both cell-intrinsic and -extrinsic pathways.
