    Polar pattern formation induced by contact following locomotion in a multicellular system

    Masayuki Hayakawa et al.
    Transient cell-cell contact of eukaryotic cells, called contact following locomotion, causes cell density segregation, and its high-density region traveled as a band within the disordered background.

    Neurexin and Neuroligin-based adhesion complexes drive axonal arborisation growth independent of synaptic activity

    William D Constance et al.
    Axonal arborisation growth is regulated by dynamic, focal localisations of Neurexin and Neuroligin that provide stability for filopodia, enabling a 'stick and grow'-based mechanism, wholly independent of synapse formation.

    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.

    Embryonic geometry underlies phenotypic variation in decanalized conditions

    Anqi Huang et al.
    Gene regulatory networks incorporate information of the embryonic geometrical parameters to give rise to differential individual patterning outputs under decanalized genetics backgrounds.

    Cooperative unfolding of distinctive mechanoreceptor domains transduces force into signals

    Lining Ju et al.
    New biophysical methods and analyses visualize in real-time a chain of coordinated single-molecular events on a living cell, enabling the inner workings of a mechanoreceptor important to biology to be elucidated.

    The horizontally-acquired response regulator SsrB drives a Salmonella lifestyle switch by relieving biofilm silencing

    Stuti K Desai et al.
    A response regulator acquired via lateral gene transfer has rewired an ancestral genetic circuitry and regulates alternative pathogenic lifestyles.

    Vibrator and PI4KIIIα govern neuroblast polarity by anchoring non-muscle myosin II

    Chwee Tat Koe et al.
    Vibrator and PI4KIIIα that stimulate the synthesis of PI(4)P anchor non-muscle myosin II RLC (Sqh) to the plasma membrane and conversely Sqh associates with PI(4)P and facilitates its membrane localization during asymmetric division of neuroblasts.

    Decoding temporal interpretation of the morphogen Bicoid in the early Drosophila embryo

    Anqi Huang et al.
    Cell fates endowed by higher Bicoid concentration require input for longer duration, demonstrating a temporally non-linear morphogen-mediated pattern formation.

    Cryo-EM structures reveal specialization at the myosin VI-actin interface and a mechanism of force sensitivity

    Pinar S Gurel et al.
    Cryo-EM structures of actomyosin VI in multiple nucleotide states reveal a unique actin-myosin interface and a mechanism of force-sensitivity; furthermore, myosin VI remodels F-actin, suggesting a role for actin structural plasticity during force generation.

    Organ sculpting by patterned extracellular matrix stiffness

    Justin Crest et al.
    Direct measurement of finely patterned mechanical properties in a native basement membrane demonstrate how force asymmetries arising from this extracellular matrix, rather than from cells, can precisely sculpt a tissue.
