    Cyanobacteria use micro-optics to sense light direction

    Nils Schuergers et al.
    The cells of a cyanobacterium act as spherical micro-lenses, allowing the cell to see a light source and move towards it.

    Determining composition of micron-scale protein deposits in neurodegenerative disease by spatially targeted optical microproteomics

    Kevin C Hadley et al.
    STOMP is a technique that can determine the proteomic composition of any feature that is identifiable by laser scanning microscopy and is at least one cubic micron in size.

    Rod nuclear architecture determines contrast transmission of the retina and behavioral sensitivity in mice

    Kaushikaram Subramanian et al.
    Establishing retinal contrast transmission as a novel determinant of mammalian fitness, this research adds functional significance to a prominent exception of nuclear organization, previously described in nocturnal rod photoreceptor cells.

    Rapid whole brain imaging of neural activity in freely behaving larval zebrafish (Danio rerio)

    Lin Cong et al.
    The integration of a novel high spatiotemporal resolution volume imaging technique and a fast 3D tracking system allows capturing whole brain neural activities in a freely behaving larval zebrafish.

    Dynamic metabolic exchange governs a marine algal-bacterial interaction

    Einat Segev et al.
    Physical and chemical interactions with bacteria influence the life and death of Emiliania huxleyi, a bloom-forming micro-alga important in global biogeochemical cycles.

    Dynamic density shaping of photokinetic E. coli

    Giacomo Frangipane et al.
    The concentration of motile bacteria, expressing a light-driven proton pump, can be precisely controlled in space and time by spatially modulating their swimming speeds with a structured light pattern.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann et al.
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

    Cytokinesis in vertebrate cells initiates by contraction of an equatorial actomyosin network composed of randomly oriented filaments

    Felix Spira et al.
    Asymmetric tension increase along the cell equator promotes self-organization of actomyosin into a partially aligned network during cytokinetic cleavage furrow ingression of vertebrate cells.

    Computational 3D histological phenotyping of whole zebrafish by X-ray histotomography

    Yifu Ding et al.
    X-ray histotomography produces the first 3-dimensional images with the combined submicron resolution, centimeter fields-of-view, soft-tissue contrast, and potential throughput to enable quantitative, histopathological and centimeter-scale phenotyping for whole-organism phenomics.

    Size control of the inner ear via hydraulic feedback

    Kishore R Mosaliganti et al.
    Size regulation of the otic vesicle, the progenitor of the inner ear, is mediated by mechanical feedback involving fluid influx, hydraulic pressure, and tissue mechanics.
