    Processing of motion boundary orientation in macaque V2

    Heng Ma et al.
    Area V2 in macaque monkeys contributes to the perception of the outlines of moving objects and achieves this through a local computation.

    Flower-like patterns in multi-species bacterial colonies

    Liyang Xiong et al.
    Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.

    Motion sensing superpixels (MOSES) is a systematic computational framework to quantify and discover cellular motion phenotypes

    Felix Y Zhou et al.
    A new computational framework provides a flexible and general approach for single and collective biological motion characterisation and phenotyping ideally suited for high-throughput timelapse screens.

    Elementary sensory-motor transformations underlying olfactory navigation in walking fruit-flies

    Efrén Álvarez-Salvado et al.
    A high-throughput behavioral paradigm and computational modeling are used to decompose olfactory navigation in walking Drosophila melanogaster into a set of quantitative relationships between sensory input and motor output.

    Control of adaptive action selection by secondary motor cortex during flexible visual categorization

    Tian-Yi Wang et al.
    The secondary motor cortex causally contributes to flexible action selection during stimulus categorization with the representations of upcoming choice and sensory history regulated by the demand to remap stimulus–action association.

    Hydrodynamics of sponge pumps and evolution of the sponge body plan

    Seyed Saeed Asadzadeh et al.
    The architecture of flagellated chambers in sponge pumps is linked to that of body plan, supporting the current view that the sponge aquiferous system evolved from an open-type filtration system.

    Dynamic curvature regulation accounts for the symmetric and asymmetric beats of Chlamydomonas flagella

    Pablo Sartori et al.
    The self-organised beat of cilia and flagella is dynamically regulated by curvature.

    A physical mechanism of TANGO1-mediated bulky cargo export

    Ishier Raote et al.
    TANGO1 functions as a linactant filament to stabilize shallow COPII-coated buds, and after which membrane tension regulation, possibly mediated by TANGO1-controlled membrane fusion, facilitates bud elongation for procollagen export.

    Centering and symmetry breaking in confined contracting actomyosin networks

    Niv Ierushalmi et al.
    Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.

    Replay as wavefronts and theta sequences as bump oscillations in a grid cell attractor network

    Louis Kang, Michael R DeWeese
    An experimentally supported model of grid cells naturally enables them to participate in firing sequences that encode rapid trajectories in space.
