    Structures in multiple conformations reveal distinct transition metal and proton pathways in an Nramp transporter

    Aaron T Bozzi et al.
    Nramp-family transporters adapt a common fold to a novel mechanism in which the spatial and temporal separation of like-charge transition metal and proton co-substrates circumvents the expected electrostatic repulsion.

    Programmed conversion of hypertrophic chondrocytes into osteoblasts and marrow adipocytes within zebrafish bones

    Dion Giovannone et al.
    Cartilage cells transition through a proliferative intermediate to give rise to bone and marrow fat cells in long bones.

    Transsynaptic interactions between IgSF proteins DIP-α and Dpr10 are required for motor neuron targeting specificity

    James Ashley et al.
    Synaptic partner recognition in the Drosophila neuromuscular circuit requires interactions between the Dpr and DIP subfamilies of immunoglobulin cell-surface proteins.

    Bumblebee visual allometry results in locally improved resolution and globally improved sensitivity

    Gavin J Taylor et al.
    Bigger bumblebee eyes have better vision, yet their field of view, sensitivity, and resolution do not all simply scale up with eye size, being improved locally instead.

    Heterodimerization of UNC-13/RIM regulates synaptic vesicle release probability but not priming in C. elegans

    Haowen Liu et al.
    RIM binding UNC-13L C2A domain releases UNC-13L from an autoinhibitory homodimeric complex to become fusion-competent, and regulates probability of synaptic vesicle release in the post-priming process.

    zGrad is a nanobody-based degron system that inactivates proteins in zebrafish

    Naoya Yamaguchi et al.
    The F-box/anti-GFP nanobody fusion protein zGrad depletes GFP-tagged proteins with spatial and temporal control in zebrafish.

    The modular mechanism of chromocenter formation in Drosophila

    Madhav Jagannathan et al.
    Cell biological study reveals the mechanism by which multiple satellite-DNA-binding proteins cooperate to form chromocenter to encapsulate the full complement of chromosomes.

    Molecular basis of synaptic specificity by immunoglobulin superfamily receptors in Drosophila

    Shouqiang Cheng et al.
    Fly protein families Dprs and DIPs can create a multitude of complementary interfaces for homo- and heterophilic adhesion complexes, resulting in instructive roles for connectivity in the motor neuron circuitry.

    Mismatch repair-signature mutations activate gene enhancers across human colorectal cancer epigenomes

    Stevephen Hung et al.
    Non-coding mutations in microsatellite-instable (MSI) colorectal tumors are prevalent and activate cancer-specific enhancers, thereby disrupting gene expression control.

    Convergent recruitment of TALE homeodomain life cycle regulators to direct sporophyte development in land plants and brown algae

    Alok Arun et al.
    TALE homeodomain transcription factors have been independently recruited to regulate gametophyte to sporophyte transitions in two complex multicellular eukaryotic supergroups, land plants in Archaeplastida and brown algae in Chromalveolata.
