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

    Aby Joseph, Andres Guevara-Torres, Jesse Schallek
    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.

    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.

    Spatial control of irreversible protein aggregation

    Christoph Weber, Thomas Michaels, L Mahadevan
    A theoretical basis for the spatial regulation of protein aggregation shows how aggregates can partition preferentially into intracellular liquid compartments.

    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.

    Mechanics and dynamics of translocating MreB filaments on curved membranes

    Felix Wong, Ethan C Garner, Ariel Amir
    Principal curvature-dependent motion of bacterial actin MreB results in localization consistent with all known literature.

    A multiphase theory for spreading microbial swarms and films

    Siddarth Srinivasan, C Nadir Kaplan, L Mahadevan
    A multiphase hydrodynamic theory reveals that the dynamics of colony expansion in microbial swarms and biofilms are limited by the constraints of water and nutrient availability.

    Biophysics: Common concepts for bacterial collectives

    Hannah Jeckel, Noémie Matthey, Knut Drescher
    The expansion of bacterial swarms and the spreading of biofilms can be described by a unified biophysical theory that involves both active and passive processes.

    Light-based tuning of ligand half-life supports kinetic proofreading model of T cell signaling

    Doug K Tischer, Orion David Weiner
    Direct control of ligand binding half-life with light shows that lifetime strongly affects T cell signaling.

    Cerebellar folding is initiated by mechanical constraints on a fluid-like layer without a cellular pre-pattern

    Andrew K Lawton, Tyler Engstrom ... Alexandra L Joyner
    A multi-phase wrinkling model accounts for the radial and circumferential tension and differential expansion between a uniformly proliferating outer fluid-like layer and an incompressible core that together drive cerebellar folding.

    Stiffness and tension gradients of the hair cell’s tip-link complex in the mammalian cochlea

    Mélanie Tobin, Atitheb Chaiyasitdhi ... Pascal Martin
    The tip-link complex of the hair cell is mechanically tuned along the tonotopic axis of the cochlea.
