    Evolutionary expansion of apical extracellular matrix is required for the elongation of cells in a novel structure

    Sarah Jacquelyn Smith et al.
    A new morphological structure evolved through extreme changes in cell height requires novel connections to an extracellular matrix network, which predates the origin of structure.

    Lin28a/let-7 pathway modulates the Hox code via Polycomb regulation during axial patterning in vertebrates

    Tempei Sato et al.
    Genetic analyses reveal that the loss of Lin28a causes axial shortening with mild skeletal transformations via decreased PRC1 at Hox genes, establishing a new pathway in the “Hox code.”.

    A tudor domain protein, SIMR-1, promotes siRNA production at piRNA-targeted mRNAs in C. elegans

    Kevin I Manage et al.
    SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.

    Activated αIIbβ3 on platelets mediates flow-dependent NETosis via SLC44A2

    Adela Constantinescu-Bercu et al.
    The interaction between activated αIIbβ3 on platelets and SLC44A2 on circulating neutrophils facilitates neutrophil capture and drives flow-dependent NETosis.

    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Spontaneous and evoked neurotransmission are partially segregated at inhibitory synapses

    Patricia M Horvath et al.
    GABAergic postsynaptic responses mediated by spontaneous and evoked neurotransmitter release are partially segregated, suggesting they may serve distinct roles in neuronal signaling.

    Nodal and planar cell polarity signaling cooperate to regulate zebrafish convergence and extension gastrulation movements

    Margot LK Williams, Lilianna Solnica-Krezel
    Nodal signaling regulates gastrulation cell behaviors largely in parallel with planar cell polarity signaling and is sufficient for ex vivo extension of embryonic explants.

    A molecular filter for the cnidarian stinging response

    Keiko Weir et al.
    Cnidarian stinging cells use a specialized voltage-gated calcium channel to integrate distinct sensory signals and selectively trigger a predatory response.
