    Geometric models for robust encoding of dynamical information into embryonic patterns

    Laurent Jutras-Dubé et al.
    Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.

    A geometric attractor mechanism for self-organization of entorhinal grid modules

    Louis Kang, Vijay Balasubramanian
    The hierarchy of entorhinal grid cell modules with constant scale ratios can self-organize through a new geometrically organized attractor mechanism.

    Drosophila uses a tripod gait across all walking speeds, and the geometry of the tripod is important for speed control

    Chanwoo Chun et al.
    Drosophila uses a gait close to the tripod throughout its speed range, and changes in speed are accompanied by changes in the geometry of the tripod.

    Epithelial geometry regulates spindle orientation and progenitor fate during formation of the mammalian epidermis

    Kimberly Box et al.
    Early in mammalian epidermal development, basal epidermal progenitor cells utilize packing and three-dimensional geometry, rather than cortical polarity cues, to inform division orientation and progenitor cell fate.

    Theoretical relation between axon initial segment geometry and excitability

    Sarah Goethals, Romain Brette
    Theoretical analysis uncovers the impact of axon initial segment plasticity on neural excitability.

    State-dependent geometry of population activity in rat auditory cortex

    Dmitry Kobak et al.
    Representation of sound lateralisation and intensity by neural population in the rat auditory cortex strongly depends on the brain state suggesting that the neural tuning to lateralisation is not hard-wired.

    Organ geometry channels reproductive cell fate in the Arabidopsis ovule primordium

    Elvira Hernandez-Lagana et al.
    In the Arabidopsis ovule primordium, germinal fate plasticity is coupled to the morphogenetic processes shaping the organ.

    Reconceiving the hippocampal map as a topological template

    Yuri Dabaghian et al.
    Empirical evidence suggests that the hippocampus constructs maps of spatial environments based on the relative locations of places (i.e., topology), rather than absolute distances and coordinates (i.e., geometry).

    Cytoskeletal tension and Bazooka tune interface geometry to ensure fusion fidelity and sheet integrity during dorsal closure

    Piyal Taru Das Gupta, Maithreyi Narasimha
    Restoration of molecular and morphological symmetry and mechanical integrity following epithelial fusion relies on adaptive changes that are mediated by cytoskeletal tension and Bazooka dependent modulation of fusing interface geometry.

    Individual variation in Achilles tendon morphology and geometry changes susceptibility to injury

    Nai-Hao Yin et al.
    Studying individual Achilles tendon geometry and interface sliding capacity may allow prediction of injury sites, and targeted training on specific muscle-(sub-)tendon units may boost beneficial outcomes for Achilles tendinopathy.
