    Unfair competition governs the interaction of pCPI-17 with myosin phosphatase (PP1-MYPT1)

    Joshua J Filter et al.
    Unfair competition, in which a phosphatase and a phosphoprotein inhibitor/substrate mutually sequester each other from competing substrates and enzymes, is a conserved mechanism for the control of PPP family phosphatases.

    Muscle Contraction: Too much of a good thing

    H Lee Sweeney
    A mutation that causes heart disease in humans increases the number of active myosin heads during contraction in the muscles of fruit flies, leading to the progressive dysfunction of the flight muscles and heart tube.

    Regional complexity in enteric neuron wiring reflects diversity of motility patterns in the mouse large intestine

    Zhiling Li et al.
    Calcium response profiling of large populations of enteric neurons reveals hard-wired neural circuits that reflect the motility program portfolio of the intestinal region they occupy.

    Physiological constraint on acrobatic courtship behavior underlies rapid sympatric speciation in bearded manakins

    Meredith C Miles et al.
    Skeletal muscle performance sets the course of rapid speciation by defining the evolutionary trajectory of reproductive behavior.

    Transition between fermentation and respiration determines history-dependent behavior in fluctuating carbon sources

    Bram Cerulus et al.
    Live-cell microscopy and genome-wide screens reveal how slow transitions in metabolism can underlie metabolic memory, providing a model for organisms demonstrating similar history-dependent behaviour and routes to improve industrial microbes.

    Cerebellar learning using perturbations

    Guy Bouvier et al.
    A proposal for a complete cellular/network implementation of trial-and-error motor learning in the olivo-cerebellar system.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    Glucose inhibits cardiac muscle maturation through nucleotide biosynthesis

    Haruko Nakano et al.
    During cardiogenesis, the major role of glucose is not the catabolic extraction of energy but the anabolic biosynthesis of nucleotides.

    Transient external force induces phenotypic reversion of malignant epithelial structures via nitric oxide signaling

    Benjamin L Ricca et al.
    In a 3D culture model of breast epithelium, application of a short-timescale compression to single malignant cells promotes the long-timescale development of polarized, growth-arrested structures.
