    Supporting cells remove and replace sensory receptor hair cells in a balance organ of adult mice

    Stephanie A Bucks et al.
    Cell fate-mapping with genetically-modified mouse models and cellular markers demonstrates that sensory hair cells in the vestibular portion of the inner ear are a dynamic population in adult mice that undergo cell death and replacement under normal conditions.

    Occurrence of long-term depression in the cerebellar flocculus during adaptation of optokinetic response

    Takuma Inoshita, Tomoo Hirano
    Motor training decreased the unit synaptic response and suppressed induction of long-term depression at parallel fiber to Purkinje cell synapses in the cerebellum, supporting involvement of long-term depression in motor learning.

    Regenerating hair cells in vestibular sensory epithelia from humans

    Ruth Rebecca Taylor et al.
    Immunolabelling and morphological assessment, complemented by complete transcriptomic analysis, demonstrates that supporting cells can be induced to convert towards a hair cell-like phenotype in human vestibular sensory epithelia.

    C/EBPδ drives interactions between human MAIT cells and endothelial cells that are important for extravasation

    Chang Hoon Lee et al.
    The bZIP transcription factor C/EBPδ enhances expression both of selectin ligands and the chemokine receptor CCR6 on human mucosal-associated invariant T cells, supporting their efficient extravasation into inflamed tissue.

    Spatial patterning of liver progenitor cell differentiation mediated by cellular contractility and Notch signaling

    Kerim B Kaylan et al.
    Mechanical stress plays a cooperative role with Notch in biliary differentiation of liver progenitors, supporting a model of liver development in which biomechanical cues are key inducers of cell fate.

    Point of View: Competency-based assessment for the training of PhD students and early-career scientists

    Michael F Verderame et al.
    A method to assess the training of scientists, based on a set of 10 core competencies, is proposed.

    Axons: The cost of communication in the brain

    Brian A MacVicar et al.
    Imaging ATP in axons reveals that they rely on glucose from the blood and lactate produced by glial cells as sources of energy.

    Point of View: Is cell size a spandrel?

    Ariel Amir
    Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.
