    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.

    Large, long range tensile forces drive convergence during Xenopus blastopore closure and body axis elongation

    David R Shook et al.
    Blastopore closure in Xenopus is driven by two morphogenic mechanisms that have strongly context dependent effects on tissue movement and that generate tensile force across tissues: convergent extension, as expected, and, unexpectedly, convergent thickening.

    Spatial patterning of liver progenitor cell differentiation mediated by cellular contractility and Notch signaling

    Kerim B Kaylan et al.
    Mechanical stress plays a cooperative role with Notch in biliary differentiation of liver progenitors, supporting a model of liver development in which biomechanical cues are key inducers of cell fate.

    Scleraxis-lineage cell depletion improves tendon healing and disrupts adult tendon homeostasis

    Katherine T Best et al.
    Adult Scleraxis-lineage cells are not required for successful tendon healing but are required for maintenance of tendon homeostasis.

    Anisotropic organization of circumferential actomyosin characterizes hematopoietic stem cells emergence in the zebrafish

    Mylene Lancino et al.
    Emergence of hematopoietic stem cells from an aortic component is a unique phenomenon of cell extrusion, with no equivalent in cell biology, and which is adapted to environmental constraints exerted by endothelial cells and hemodynamics forces.

    Mechanical force induces mitochondrial fission

    Sebastian Carsten Johannes Helle et al.
    Mechanically stimulating mitochondria causes them to divide via the recruitment of the mitochondrial fission machinery to the mechanically strained site, showing that intracellular organelles can be mechanoresponsive.

    Burst muscle performance predicts the speed, acceleration, and turning performance of Anna’s hummingbirds

    Paolo S Segre et al.
    Maneuverability is thought to be limited by either intrinsic constraints or physiological capacity, and automated tracking of flying hummingbirds reveals that muscle capacity explains much of the variation in their flight trajectories.

    FBN-1, a fibrillin-related protein, is required for resistance of the epidermis to mechanical deformation during C. elegans embryogenesis

    Melissa Kelley et al.
    A fibrillin-related protein, FBN-1, is a key component of the apical extracellular matrix and prevents epidermal cell deformation by biomechanical forces during morphogenesis of the C. elegans embryo.

    Non-canonical Wnt signaling regulates junctional mechanocoupling during angiogenic collective cell migration

    Joana R Carvalho et al.
    Analysis of axial polarity distributions shows that Wnt5a regulates collective cell migration in vivo by stabilizing vinculin at adherens junctions and fine-tuning mechanocoupling between neighbouring cells.

    Islet vascularization is regulated by primary endothelial cilia via VEGF-A-dependent signaling

    Yan Xiong et al.
    Primary cilia on endothelial cells are required for VEGF-A/ VEGFR2-dependent signaling, islet vascularization and, consequently, nutrient delivery and insulin disposal.
