    Temporal integration of auxin information for the regulation of patterning

    Carlos S Galvan-Ampudia, Guillaume Cerutti ... Teva Vernoux
    Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

    Partial connectomes of labeled dopaminergic circuits reveal non-synaptic communication and axonal remodeling after exposure to cocaine

    Gregg Wildenberg, Anastasia Sorokina ... Bobby Kasthuri
    3D serial electron microscopy reveals that individual dopamine axons in the nucleus accumbens contain different varicosity types based on their vesicle contents, rarely make synapses, and undergo major structural plasticity in response to cocaine.

    Cortical flow aligns actin filaments to form a furrow

    Anne-Cecile Reymann, Fabio Staniscia ... Stephan W Grill
    Compressing the actomyosin network by cortical flow causes filaments to align and form a constricting ring.

    Mimicry can drive convergence in structural and light transmission features of transparent wings in Lepidoptera

    Charline Sophie Pinna, Maëlle Vilbert ... Marianne Elias
    Wing transparency in mimetic butterflies and moths is achieved by an unexpected diversity of structural features, and both structures and light transmission properties of wings are under selection for convergence.
