    Impaired skeletal muscle mitochondrial pyruvate uptake rewires glucose metabolism to drive whole-body leanness

    Arpit Sharma et al.
    Skeletal muscle mitochondrial pyruvate carrier disruption increases muscle fatty acid oxidation and systemic glucose turnover that drive whole-body leanness.

    Optical estimation of absolute membrane potential using fluorescence lifetime imaging

    Julia R Lazzari-Dean et al.
    Fluorescence lifetime imaging microscopy, paired with fluorescent, voltage-sensitive dyes, provides a method for measuring and quantifying membrane potentials of living cells.

    Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1

    Leanne M Holt et al.
    Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.

    Metformin extends C. elegans lifespan through lysosomal pathway

    Jie Chen et al.
    Metformin extends C. elegans lifespan through lysosome-dependent coordination of TORC1 and AMPK pathways.

    Frequency-dependent mobilization of heterogeneous pools of synaptic vesicles shapes presynaptic plasticity

    Frédéric Doussau et al.
    The mobilization or silencing of two heterogeneous pools of synaptic vesicles via different frequencies probably enables granule cell to Purkinje cell synapses to better discriminate between the high-rate code of sensory information and background noise.

    Bidirectional encoding of motion contrast in the mouse superior colliculus

    Jad Barchini et al.
    Two photon calcium imaging experiments show that excitatory and inhibitory neurons in the mouse superior colliculus are differentially modulated by the motion contrast between stimulus center and surround.

    Irreversible temperature gating in trpv1 sheds light on channel activation

    Ana Sánchez-Moreno et al.
    Temperature-activated TRPV1 ion channels respond to increased temperatures by opening and then entering an inactivated state from which they cannot recover, suggesting that this form of irreversible gating results from partial unfolding during heat absorption.

    Doc2B acts as a calcium sensor for vesicle priming requiring synaptotagmin-1, Munc13-2 and SNAREs

    Sébastien Houy et al.
    Doc2B functions in two distinct vesicle priming steps; membrane localization occludes upstream Ca2+-dependent priming, whereas Ca2+-binding and interaction with synaptotagmin-1, SNAREs, and Munc13-2 are involved in downstream priming, which makes vesicles readily releasable.

    Stiffness and tension gradients of the hair cell’s tip-link complex in the mammalian cochlea

    Mélanie Tobin et al.
    The tip-link complex of the hair cell is mechanically tuned along the tonotopic axis of the cochlea.

    PARIS, an optogenetic method for functionally mapping gap junctions

    Ling Wu et al.
    As the first fully genetically encoded method, PARIS allows cell-specific, long-term, repeated measurements of gap junctional coupling with high spatiotemporal resolution, facilitating its study in both health and disease.
