    Quantification of gait parameters in freely walking wild type and sensory deprived Drosophila melanogaster

    César S Mendes et al.
    Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.

    Decoding the neural mechanisms of human tool use

    Jason P Gallivan et al.
    Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.

    Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors

    Roberto A Keller et al.
    Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.

    Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription

    Vincenzo Di Cerbo et al.
    The acetylation of histones at specific sites close to DNA can regulate transcription.

    Subcellular and supracellular mechanical stress prescribes cytoskeleton behavior in Arabidopsis cotyledon pavement cells

    Arun Sampathkumar et al.
    In the Arabidopsis epidermis, the internal mechanical stress of a cell competes with the external stress to control microtubule behavior, providing a framework to understand the mechanical feedbacks that underlie plant morphogenesis.

    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.

    Texture coarseness responsive neurons and their mapping in layer 2–3 of the rat barrel cortex in vivo

    Liora Garion et al.
    Neurons within rat somatosensory cortex are selective to texture and are spatially organized according to their texture preference.

    Cannabinoid-induced actomyosin contractility shapes neuronal morphology and growth

    Alexandre B Roland et al.
    Cannabinoids inhibit neuronal expansion and growth through the rapid contraction of actomyosin.

    A bacteriophage tubulin harnesses dynamic instability to center DNA in infected cells

    Marcella L Erb et al.
    A bacteriophage tubulin homolog, PhuZ, forms a structure with the biochemical, structural, and functional properties of a simplified, bipolar spindle.
