    Spontaneous body wall contractions stabilize the fluid microenvironment that shapes host–microbe associations

    Janna C Nawroth, Christoph Giez ... Thomas CG Bosch
    Spontaneous contractions allow shedding of the fluid boundary layer and thereby stabilize microbiota.

    Control of telomere length in yeast by SUMOylated PCNA and the Elg1 PCNA unloader

    Pragyan Singh, Inbal Gazy, Martin Kupiec
    SUMOylated PCNA and the Elg1 PCNA unloader interact with the CST complex to coordinate DNA replication and telomere length maintenance.

    Vitamin D induces SIRT1 activation through K610 deacetylation in colon cancer

    José Manuel García-Martínez, Ana Chocarro-Calvo ... Custodia García-Jiménez
    Vitamin D bound to its receptor interacts with SIRT1 to induce its auto deacetylation and catalytic activity, which drives anti-proliferative effects in colorrectal cancer and this may lead to new therapeutic approaches for colorrectal and perhaps other cancers.

    Homeodomain-interacting protein kinase maintains neuronal homeostasis during normal Caenorhabditis elegans aging and systemically regulates longevity from serotonergic and GABAergic neurons

    Maria I Lazaro-Pena, Adam B Cornwell ... Andrew V Samuelson
    The transcriptional cofactor HPK-1 (homeodomain-interacting protein kinase) functions as a key regulator of multiple proteostatic stress responses, each originating from discrete neuronal subtypes within the Caenorhabditis elegans nervous system to preserve neuronal health and maintain organismal proteostasis during normal aging.

    Uncovering circuit mechanisms of current sinks and sources with biophysical simulations of primary visual cortex

    Atle E Rimehaug, Alexander J Stasik ... Anton Arkhipov
    A biophysically detailed model of mouse primary visual cortex reproduces, in a quantitative manner, experimentally recorded spikes and local field potentials, and suggests mechanisms that form current sinks and sources in vivo.

    Forkhead transcription factor FKH-8 cooperates with RFX in the direct regulation of sensory cilia in Caenorhabditis elegans

    Rebeca Brocal-Ruiz, Ainara Esteve-Serrano ... Nuria Flames
    In sensory ciliated neurons, FoxN4 Forkhead (FKH) transcription factors directly coregulate transcription of ciliome genes together with RFX transcription factors, a similar regulatory logic to what is found for motile-cilium cell types, suggesting an ancestral origin for this partnership.

    The functional form of value normalization in human reinforcement learning

    Sophie Bavard, Stefano Palminteri
    Challenging a popular theory in neuroeconomics, a computational cognitive study provides evidence against divisive normalization, a supposedly canonical neural computation, in favor of an alternative account, range normalization, in the context of value learning.

    How inhibitory and excitatory inputs gate output of the inferior olive

    Sebastián Loyola, Tycho M Hoogland ... Chris I De Zeeuw
    Experimental work and computational models reveal how the timing between the inhibitory and excitatory inputs modulates the function of the inferior olive nucleus, a key structure for motor learning and cognition.

    Plant secondary metabolite-dependent plant-soil feedbacks can improve crop yield in the field

    Valentin Gfeller, Jan Waelchli ... Matthias Erb
    A 2-year field experiment reveals that plant secondary metabolites can be harnessed to increase crop productivity through plant-soil feedbacks under agronomically realistic conditions.

    Inhibition of DNMT1 methyltransferase activity via glucose-regulated O-GlcNAcylation alters the epigenome

    Heon Shin, Amy Leung ... Dustin E Schones
    Extracellular glucose promotes O-GlcNAcylation of DNMT1 and inhibition of DNMT1 function in the maintenance of genomic methylation.
