Making a link between deletion of transcription cis-regulatory elements by CrispR/Cas9, obtention of mutants with single muscle morphology defects and their impact on locomotion.
Functional attachments between muscles and tendons require pentameric Thrombospondin-4, revealing novel roles both as an integrin ligand and extracellular matrix scaffold.
In vitro grown human muscle fibers display remarkable self-organisation capacities at the tissue, cellular, and molecular levels that are coordinated by mechanical tension.

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 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.

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.

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 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.
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.
