    Morphogenesis: Mathematical models with frills

    Pierre A Haas
    The spectacular frill around the neck of the lizard Chlamydosaurus has its origins in a mechanical instability that arises during development.

    Elastic instability during branchial ectoderm development causes folding of the Chlamydosaurus erectile frill

    Sophie A Montandon et al.
    Robust wrinkling pattern of the frilled dragon’s spectacular erectile ruff emerges from an elastic instability during homogeneous growth of the embryonic neck fold frustrated by its attachment to adjacent tissues.

    Nanoresolution real-time 3D orbital tracking for studying mitochondrial trafficking in vertebrate axons in vivo

    Fabian Wehnekamp et al.
    The ability to follow single objects in 3D in a living organism with high spatiotemporal resolution opens new possibilities for quantitative biophysical studies of complex systems in their physiological context.

    Shared behavioral mechanisms underlie C. elegans aggregation and swarming

    Siyu Serena Ding et al.
    Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.

    Spatiotemporal organization of branched microtubule networks

    Akanksha Thawani et al.
    A sequential reaction pathway involving TPX2, augmin and γ-TuRC governs the assembly and architecture of branched microtubule networks.

    Spatial control of irreversible protein aggregation

    Christoph Weber et al.
    A theoretical basis for the spatial regulation of protein aggregation shows how aggregates can partition preferentially into intracellular liquid compartments.

    Influenza A virus surface proteins are organized to help penetrate host mucus

    Michael D Vahey, Daniel A Fletcher
    By distributing receptor-binding and receptor-destroying proteins asymmetrically on their surface, filamentous influenza A virus particles create a Brownian ratchet that facilitates their passage through mucus.

    Imaging single-cell blood flow in the smallest to largest vessels in the living retina

    Aby Joseph et al.
    By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.

    Environmental heterogeneity can tip the population genetics of range expansions

    Matti Gralka, Oskar Hallatschek
    Environmental heterogeneity can dramatically reduce the efficacy of selection and alter the neutral evolutionary dynamics in microbial range expansions.
