    Massive normalization of olfactory bulb output in mice with a 'monoclonal nose'

    Benjamin Roland et al.
    Inhibitory circuits in the olfactory bulb can amplify or suppress sensory inputs over a wide range of intensities to generate robust mitral cell output.

    Adaptation of spontaneous activity in the developing visual cortex

    Marina E Wosniack et al.
    To generate stable and robust connectivity refinements, the amplitude of spontaneous activity events in the developing visual cortex adapts to the recent history of cortical activation.

    A quantitative approach for analyzing the spatio-temporal distribution of 3D intracellular events in fluorescence microscopy

    Thierry Pécot et al.
    QuantEv is a fully automatic and semi-parametric method that allows quantitative analysis of the spatio-temporal distribution of complex molecular trafficking objects at the scale of the whole cell.

    Transparent soil microcosms for live-cell imaging and non-destructive stable isotope probing of soil microorganisms

    Kriti Sharma et al.
    Two optically transparent substrates enable the exploration of the ecophysiology and spatiotemporal organization and activities of bacteria and fungi within heterogeneous soil-like environments.

    Retrieval practice facilitates memory updating by enhancing and differentiating medial prefrontal cortex representations

    Zhifang Ye et al.
    Retrieval practice strongly engages the medial prefrontal cortex to integrate and differentiate memory representations, resulting in more effective memory updating.

    Asymmetric ON-OFF processing of visual motion cancels variability induced by the structure of natural scenes

    Juyue Chen et al.
    The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.

    Mitochondrial biogenesis is transcriptionally repressed in lysosomal lipid storage diseases

    King Faisal Yambire et al.
    Transcription factors KLF2 and ETV1 repress the transcriptional program of mitochondrial biogenesis, resulting in impaired mitochondrial function in lysosomal storage diseases.

    Genome-wide interrogation of extracellular vesicle biology using barcoded miRNAs

    Albert Lu et al.
    A screen using artificially barcoded, exosomal microRNAs, paired with CRISPR guide RNAs, helped identify new players in multivesicular endosome exocytosis and a role for Wnt signaling.

    VivosX, a disulfide crosslinking method to capture site-specific, protein-protein interactions in yeast and human cells

    Chitra Mohan et al.
    An in vivo disulfide crosslinking assay shows preferential disassembly of nucleosomes with two H2A.Z histones by transcription machinery in yeast and conjugation to one or two ubiquitin moieties in human cells.

    H3.3K27M mutant proteins reprogram epigenome by sequestering the PRC2 complex to poised enhancers

    Dong Fang et al.
    Redistribution of the PRC2 complex in H3.3K27M mutant cells to poised enhancers contributes to the global reduction of H3K27me3 in cells expressing the mutant proteins.
