    Thrombospondin-4 controls matrix assembly during development and repair of myotendinous junctions

    Arul Subramanian, Thomas F Schilling
    Functional attachments between muscles and tendons require pentameric Thrombospondin-4, revealing novel roles both as an integrin ligand and extracellular matrix scaffold.

    Tension-driven multi-scale self-organisation in human iPSC-derived muscle fibers

    Qiyan Mao, Achyuth Acharya ... Frank Schnorrer
    In vitro grown human muscle fibers display remarkable self-organisation capacities at the tissue, cellular, and molecular levels that are coordinated by mechanical tension.

    Single-molecule imaging reveals the concerted release of myosin from regulated thin filaments

    Quentin M Smith, Alessio V Inchingolo ... Neil M Kad
    Direct single molecule visualization of striated muscle relaxation using thin filament tightropes reveals the concerted release of myosins, with implications for models of muscle function.

    Thrombospondin expression in myofibers stabilizes muscle membranes

    Davy Vanhoutte, Tobias G Schips ... Jeffery D Molkentin
    Thrombospondin proteins regulate vesicular trafficking of integrins and other membrane attachment complex proteins to the plasma membrane of skeletal muscle, which provides greater stability and resistance to muscular dystrophy.

    Novel functions for integrin-associated proteins revealed by analysis of myofibril attachment in Drosophila

    Hannah J Green, Annabel GM Griffiths ... Nicholas H Brown
    Integrin and actin associated proteins are resolved into four layers within myofibril attachments, an architecture requiring balanced positive and negative regulation of integrin adhesion with integrated mechanotransduction and actin pathways.

    Mechanical force regulates tendon extracellular matrix organization and tenocyte morphogenesis through TGFbeta signaling

    Arul Subramanian, Lauren Fallon Kanzaki ... Thomas Friedrich Schilling
    Perturbation of mechanical force at muscle attachments and its effects on tendon morphogenesis provides insights into the mechanisms underlying cellular responses to tensional force and resulting extracellular matrix production.

    A non-archaeopterygid avialan theropod from the Late Jurassic of southern Germany

    Oliver WM Rauhut, Helmut Tischlinger, Christian Foth
    A new taxon from the Late Jurassic of southern Germany represents the second volant bird known from that time period and documents the improvement of flapping flight in bird evolution.

    Bipolar filaments of human nonmuscle myosin 2-A and 2-B have distinct motile and mechanical properties

    Luca Melli, Neil Billington ... James R Sellers
    Individual nonmuscle myosin 2 filaments in cells may differ their mechanical and kinetic properties depending on the myosin paralog composition giving the cells a mechanism for fine tuning the output of a given nonmuscle myosin filament.

    Extreme suction attachment performance from specialised insects living in mountain streams (Diptera: Blephariceridae)

    Victor Kang, Robin T White ... Walter Federle
    Net-winged midge larvae use suction organs covered in spine-like cuticular protrusions to generate powerful attachment on wet and rough surfaces.
