    Two consecutive microtubule-based epithelial seaming events mediate dorsal closure in the scuttle fly Megaselia abdita

    Juan Jose Fraire-Zamora et al.
    Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

    Proliferation-independent regulation of organ size by Fgf/Notch signaling

    Agnė Kozlovskaja-Gumbrienė et al.
    Cell adhesion regulates organ size in the zebrafish lateral line system.

    Murine Fam65b forms ring-like structures at the base of stereocilia critical for mechanosensory hair cell function

    Bo Zhao et al.
    Super-resolution microscopy reveals a highly organized compartment in the stereocilia of mechanosensory hair cells of the inner ear, which is critical for hair cell function and affected in disease.

    Sensory dynamics of visual hallucinations in the normal population

    Joel Pearson et al.
    A new method for inducing, measuring and modelling visual hallucinations in healthy people reveals that hallucinations share common underlying mechanisms with normal sensory perception.

    Dopamine neuron ensembles signal the content of sensory prediction errors

    Thomas A Stalnaker et al.
    Dopamine neurons function as an ensemble to signal a multidimensional feature prediction error.

    An integrative genomic analysis of the Longshanks selection experiment for longer limbs in mice

    João PL Castro et al.
    Genome sequencing of mice selected for longer limbs reveals that rapid selection response is due to both discrete loci and polygenic adaptation.

    A multicellular way of life for a multipartite virus

    Anne Sicard et al.
    A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.

    Zygotic gene activation in the chicken occurs in two waves, the first involving only maternally derived genes

    Young Sun Hwang et al.
    In Aves, the first wave of transcription is derived exclusively from the maternal genome.
    1. Neuroscience

    Output variability across animals and levels in a motor system

    Angela Wenning et al.
    Population output variability in a motor control system varies across levels (CPG, motor neurons, muscles) and can be ascribed to life history differences among animals and in some cases to differences between bilaterally homologous elements.
