    Action does not enhance but attenuates predicted touch

    Xavier Job, Konstantina Kilteni
    A series of pre-registered psychophysical studies on self-touch tested two opposing models of somatosensory attenuation (cancelation) and enhancement (sharpening) regarding how action affects perception, and revealed that action prediction produces an attenuation, and not an enhancement, of the predicted touch.

    Postsynaptic cell type and synaptic distance do not determine efficiency of monosynaptic rabies virus spread measured at synaptic resolution

    Maribel Patiño, Willian N Lagos ... Edward M Callaway
    Under typical monosynaptic rabies tracing conditions about 40% of first-order presynaptic synapses to cortical neurons are labeled and spread efficiency does not vary depending on the distance of synapses to the cell body, across dendrite types, or starter neuron types.

    A randomized multiplex CRISPRi-Seq approach for the identification of critical combinations of genes

    Nicole A Ellis, Kevin S Myers ... Matthias P Machner
    A randomized CRISPR-based gene silencing approach overcomes functional redundancy and discovers virulence-critical gene combinations in the pathogen Legionella pneumophila.

    Steroidogenesis and androgen/estrogen signaling pathways are altered in in vitro matured testicular tissues of prepubertal mice

    Laura Moutard, Caroline Goudin ... Christine Rondanino
    Although complete mouse in vitro spermatogenesis can be achieved, failure of adult Leydig cell development, with accumulation of progesterone and estradiol, androstenedione deficiency, deregulation of steroidogenic, and steroid target gene expression, were highlighted in organotypic cultures, even with hCG.

    Repeatability of adaptation in sunflowers reveals that genomic regions harbouring inversions also drive adaptation in species lacking an inversion

    Shaghayegh Soudi, Mojtaba Jahani ... Sam Yeaman
    Adaptation to climate in sunflowers is highly polygenic, but still involves significant repeatability with many of the same genes being used by multiple species.

    Ulk4 promotes Shh signaling by regulating Stk36 ciliary localization and Gli2 phosphorylation

    Mengmeng Zhou, Yuhong Han, Jin Jiang
    Phosphorylation of the pseudokinase Ulk4 by Stk36 promotes primary ciliary tip localization of both proteins to facilitate the phosphorylation and activation of Gli in response to Sonic hedgehog.

    Multicellular factor analysis of single-cell data for a tissue-centric understanding of disease

    Ricardo Omar Ramirez Flores, Jan David Lanzer ... Julio Saez-Rodriguez
    A computational framework allows the unsupervised analysis of samples from single cell data across conditions, inference of multicellular programs associated with disease, and meta-analysis of independent patient cohorts.

    On the role of nucleotides and lipids in the polymerization of the actin homolog MreB from a Gram-positive bacterium

    Wei Mao, Lars D Renner ... Rut Carballido-Lopez
    First 3D-structure and first observation of organized protofilaments of MreB from a Gram-positive bacterium, suggesting a model where ATP drives the formation of dynamic pairs of MreB protofilaments on a lipid surface.

    Plasma growth hormone pulses induce male-biased pulsatile chromatin opening and epigenetic regulation in adult mouse liver

    Andy Rampersaud, Jeannette Connerney, David J Waxman
    Pulsatile chromatin opening stimulated by naturally-occurring plasma growth hormone pulses is one of two GH-determined mechanisms that establish widespread sex differences in hepatic chromatin accessibility and epigenetic regulation, both closely linked to sex differences in liver gene transcription and function.

    LRRC23 truncation impairs radial spoke 3 head assembly and sperm motility underlying male infertility

    Jae Yeon Hwang, Pengxin Chai ... Jean-Ju Chung
    LRRC23 is a radial spoke 3 head component essential for normal sperm motility and fertility in mammals.
