    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.

    The visual pigment xenopsin is widespread in protostome eyes and impacts the view on eye evolution

    Clemens Christoph Döring et al.
    The employment of xenopsin in ciliary and mixed microvillar/ciliary eye sensory cells in several protostome animals suggests high evolutionary plasticity of photoreceptors.

    New insights on the modeling of the molecular mechanisms underlying neural maps alignment in the midbrain

    Elise Laura Savier et al.
    A dominant sensory map provides positional information through correlated activity and transposed molecular cues to guide secondary sensory projections for alignment and organization.

    Pattern regulation in a regenerating jellyfish

    Chiara Sinigaglia et al.
    Clytia jellyfish regenerate body shape and organs through a mechanically driven process that coordinates tissue remodeling, localized proliferation, and precursor migration and promotes Wnt signaling at a muscle-based landmark.

    Unexplained repeated pregnancy loss is associated with altered perceptual and brain responses to men’s body-odor

    Liron Rozenkrantz et al.
    Women with unexplained miscarriages have an altered behavioral and brain response to men's body-odor, and this may reflect a factor in their condition.

    Genome expansion in early eukaryotes drove the transition from lateral gene transfer to meiotic sex

    Marco Colnaghi et al.
    Lateral gene transfer is unable to resist mutation accumulation in large genomes, leading to selective pressure for the origin of meiotic sex in the first eukaryotes.

    Enteric glia as a source of neural progenitors in adult zebrafish

    Sarah McCallum et al.
    Characterization of a novel population of enteric nervous system glial cells in zebrafish reveals their proliferative and neurogenic properties under homeostatic conditions in adults, properties difficult to model in mammals.
