    Large-scale neural dynamics in a shared low-dimensional state space reflect cognitive and attentional dynamics

    Hayoung Song, Won Mok Shim, Monica D Rosenberg
    People’s neural activity travels between a small number of brain states based on what they are thinking and paying attention to.

    Reinforcement biases subsequent perceptual decisions when confidence is low, a widespread behavioral phenomenon

    Armin Lak, Emily Hueske ... Adam Kepecs
    Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.

    High-phytate/low-calcium diet is a risk factor for crystal nephropathies, renal phosphate wasting, and bone loss

    Ok-Hee Kim, Carmen J Booth ... Byung-Chul Oh
    A high-phytate-low Ca2+ diet causes crystal nephropathies, renal phosphate wasting, and bone disease in rats, whereas high Ca2+ intake ameliorates the detrimental effects of a high-phytate diet.

    Mother cells control daughter cell proliferation in intestinal organoids to minimize proliferation fluctuations

    Guizela Huelsz-Prince, Rutger Nico Ulbe Kok ... Jeroen S van Zon
    Tracking of all cells in intestinal organoids crypts to fully reconstruct cell lineages reveals that proliferative behavior is highly symmetric between sisters cells, while simulations show that this observed symmetry minimizes random fluctuations in cell proliferation, thereby ensuring homeostasis.

    Stage-dependent differential influence of metabolic and structural networks on memory across Alzheimer’s disease continuum

    Kok Pin Ng, Xing Qian ... Alzheimer's Disease Neuroimaging Initiative
    The early influence of the breakdown of both hippocampal structural network and angular gyrus-seeded default mode metabolism network on memory performance underscore the importance of early intervention in preclinical Alzheimer’s disease.

    Constitutive turnover of histone H2A.Z at yeast promoters requires the preinitiation complex

    Michael Tramantano, Lu Sun ... Ed Luk
    The transcription machinery is required for the disassembly of the promoter-proximal H2A.Z nucleosome, contributing to the constitutive histone turnover at yeast promoters.

    Applications of genetic-epigenetic tissue mapping for plasma DNA in prenatal testing, transplantation and oncology

    Wanxia Gai, Ze Zhou ... YM Dennis Lo
    Epigenetic determination of tissue of origin of genetically classified subsets of plasma DNA molecules enhances transplantation monitoring and cancer testing.

    Dysregulation of sonic hedgehog signaling causes hearing loss in ciliopathy mouse models

    Kyeong-Hye Moon, Ji-Hyun Ma ... Jinwoong Bok
    Developmental defects of the cochlea caused by dysregulation of sonic hedgehog signaling are the potential etiology for hearing loss in a group of ciliopathies with defective ciliogenesis.

    Remapping in a recurrent neural network model of navigation and context inference

    Isabel IC Low, Lisa M Giocomo, Alex H Williams
    Recurrent neural networks trained to navigate and infer latent states exhibit strikingly similar remapping patterns to those observed in navigational brain areas, inspiring new analyses of published data and suggesting a possible function for spontaneous remapping to support context-dependent navigation.

    Genome-wide errant targeting by Hairy

    Kurtulus Kok, Ahmet Ay ... David N Arnosti
    Pervasive ‘futile cycling’ by chromatin-modifying factors suggests a mechanism for creating new links in gene regulatory networks.
