    Test of the 'glymphatic' hypothesis demonstrates diffusive and aquaporin-4-independent solute transport in rodent brain parenchyma

    Alex J Smith et al.
    Solute movement in brain extracellular space is determined by solute diffusion, and does not depend on convection or aquaporin-4 expression as predicted by the glymphatic mechanism.

    Spatiotemporal regulation of autophagy during Caenorhabditis elegans aging

    Jessica T Chang et al.
    Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.

    A predictive focus of gain modulation encodes target trajectories in insect vision

    Steven D Wiederman et al.
    Visual neurons in the dragonfly predict the path of a moving target, even when it is occluded or crosses from one eye to the other.

    Pioneer neurog1 expressing cells ingress into the otic epithelium and instruct neuronal specification

    Esteban Hoijman et al.
    Quantitative 4D image analysis identifies a group of cells which enter into the otic primordium during morphogenesis and instructs neuronal specification.

    Multiplex image-based autophagy RNAi screening identifies SMCR8 as ULK1 kinase activity and gene expression regulator

    Jennifer Jung et al.
    An image-based multiplex autophagosome RNAi screen targeting all Rab GTPases as well as their GAPs and GEFs identifies the Rab GEF SMCR8 as multifaceted autophagy modulator, which regulates kinase activity and gene expression of ULK1.

    Sexual selection gradients change over time in a simultaneous hermaphrodite

    Jeroen NA Hoffer et al.
    The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

    Control of AMPA receptor activity by the extracellular loops of auxiliary proteins

    Irene Riva et al.
    Glutamate receptor auxiliary proteins exert their effects on receptor gating through two divergent extracellular loops, explaining subunit specificity and allowing the construction of null versions that form complexes normally but do not modify receptor gating.

    Distinct modes of SMAD2 chromatin binding and remodeling shape the transcriptional response to NODAL/Activin signaling

    Davide M Coda et al.
    NODAL/Activin-induced SMAD2 binding directly drives remodeling of both open and closed chromatin and does not directly correlate with temporal patterns of gene expression upon prolonged signaling.

    Poor coherence in older people's speech is explained by impaired semantic and executive processes

    Paul Hoffman et al.
    Remaining focused on the topic at hand when speaking depends on effective selection of task-relevant semantic knowledge, and declines in this ability account for increases in off-topic speech in older people.

    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.
