    Select forelimb muscles have evolved superfast contractile speed to support acrobatic social displays

    Matthew J Fuxjager et al.
    In situ measurements of muscular twitch speed reveal one of the fastest vertebrate limb muscles on record, which evolved in association with extravagant courtship displays that include rapid limb movements.

    A circuit-dependent ROS feedback loop mediates glutamate excitotoxicity to sculpt the Drosophila motor system

    Jhan-Jie Peng et al.
    Glutamate excitotoxicity induces a circuit-dependent ROS feedback loop to alter motor system integrity.

    Prolonged cross-bridge binding triggers muscle dysfunction in a Drosophila model of myosin-based hypertrophic cardiomyopathy

    William A Kronert et al.
    Integrative analysis of a Drosophila model of hypertrophic cardiomyopathy demonstrates that prolonged binding of the myosin cross-bridge to actin is a root cause of the disorder.

    The Drosophila formin Fhos is a primary mediator of sarcomeric thin-filament array assembly

    Arkadi Shwartz et al.
    Actin is incorporated into the thin-filament arrays of skeletal muscle sarcomeres in discrete steps, and Fhos, the Drosophila homolog of FHOD-family formins, is an essential player in the process.

    Antagonistic effects of intraspecific cooperation and interspecific competition on thermal performance

    Hsiang-Yu Tsai et al.
    By integrating theoretical and empirical approaches, the results show that linking abiotic factor and biotic interactions on the niche width will be critical for understanding species-specific responses to climate change.

    Angiopoietin-4-dependent venous maturation and fluid drainage in the peripheral retina

    Harri Elamaa et al.
    Identification of importance of Angiopoietin-4 (Angpt4) as a first growth factor that initiates venous specification in the peripheral retina, and Angpt4-dependent mechanism for fluid clearance in the mouse retina.

    Distinct contributions of the thin and thick filaments to length-dependent activation in heart muscle

    Xuemeng Zhang et al.
    The Frank–Starling law of the heart and its underlying mechanism of length-dependent activation involve distinctive structural changes in both the thin and thick filaments of cardiac muscle cells.

    Control of lipid domain organization by a biomimetic contractile actomyosin cortex

    Sven Kenjiro Vogel et al.
    Building on previous work (Vogel et al., 2013b), it is shown that myosin-driven actin filament rearrangements actively move, split or fuse individual lipid domains and change their overall shape.

    Spinal microcircuits comprising dI3 interneurons are necessary for motor functional recovery following spinal cord transection

    Tuan V Bui et al.
    A genetically-defined population of spinal interneurons is reciprocally connected with spinal locomotor circuits and mediates recovery of locomotor function following spinal cord transection.

    Neuroprotective effects of TRPA1 channels in the cerebral endothelium following ischemic stroke

    Paulo Wagner Pires, Scott Earley
    Acute hypoxia activates TRPA1 channels in cerebral artery endothelial cells to activate an early adaptive response to reduce tissue ischemic damage through vasodilation.
