    TMEM95 is a sperm membrane protein essential for mammalian fertilization

    Ismael Lamas-Toranzo et al.
    TMEM95, a protein localized to the sperm acrosome cap, is essential for fertilization.

    A mammalian Wnt5a–Ror2–Vangl2 axis controls the cytoskeleton and confers cellular properties required for alveologenesis

    Kuan Zhang et al.
    Regulation of cellular properties such as ligand secretion and migratory ability through changes in the cytoskeleton mediated by a Wnt5a–Ror2–Vangl2 axis is a major determinant of alveolar formation.

    Protein phosphatase 1 activity controls a balance between collective and single cell modes of migration

    Yujun Chen et al.
    Protein phosphatase 1 activity promotes cohesive collective cell migration by restricting actomyosin contractility to the periphery of the collective and maintaining proper cadherin–catenin complex protein levels at cell–cell junctions.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Sex-determining genes distinctly regulate courtship capability and target preference via sexually dimorphic neurons

    Kenichi Ishii et al.
    Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.

    A single-cell transcriptomic atlas of the adult Drosophila ventral nerve cord

    Aaron M Allen et al.
    A single-cell atlas of the adult fly VNC charts the types and properties of cells for future studies of brain development and function.

    Cre-assisted fine-mapping of neural circuits using orthogonal split inteins

    Haojiang Luan et al.
    A genetic method allows neurons to be individually identified and characterized by combining information about both their developmental origins and their mature patterns of gene expression.

    A processive rotary mechanism couples substrate unfolding and proteolysis in the ClpXP degradation machinery

    Zev A Ripstein et al.
    Understanding of bacterial protein degradation is illuminated by cryo-EM structures of the substrate-bound ClpXP complex from Neisseria meningitidis at 2.3 to 3.3 Å resolution.

    Antagonistic regulation by insulin-like peptide and activin ensures the elaboration of appropriate dendritic field sizes of amacrine neurons

    Jiangnan Luo et al.
    Afferent-derived factors control the elaboration of appropriate and robust sizes of dendritic arbors by dynamically modulating dendritic growth parameters.
