    Graphical-model framework for automated annotation of cell identities in dense cellular images

    Shivesh Chaudhary, Sol Ah Lee ... Hang Lu
    Unbiased and automatic annotation using structured prediction framework with efficiently built data-driven atlases is more accurate than registration-based methods for cell identifications in dense images and enables fast whole-brain analysis.

    CEM500K, a large-scale heterogeneous unlabeled cellular electron microscopy image dataset for deep learning

    Ryan Conrad, Kedar Narayan
    'Cellular Electron Microscopy 500,000 images' (CEM500K) is a highly heterogeneous, information-rich, non-redundant, unlabeled EM dataset curated to pre-train DL algorithms for better model generalization on EM segmentation tasks.

    Uncovering the computational mechanisms underlying many-alternative choice

    Armin W Thomas, Felix Molter, Ian Krajbich
    A comparison of different computational models reveals that looking behavior, during value-based choices from 9, 16, 25, or 36 snack foods, actively influences the subjective values of the available alternatives.

    Identification of human glucocorticoid response markers using integrated multi-omic analysis from a randomized crossover trial

    Dimitrios Chantzichristos, Per-Arne Svensson ... Gudmundur Johannsson
    A human experimental model for physiological glucocorticoid exposure and glucocorticoid withdrawal identifies a multi-omic cluster, including microRNA miR-122-5p and metabolites, associated with glucocorticoid-responsive genes.

    Control and regulation of acetate overflow in Escherichia coli

    Pierre Millard, Brice Enjalbert ... Fabien Létisse
    Elucidating the control and regulation of acetate overflow in E. coli reveals that acetate is not only an end-product but also a co-substrate and a global regulator of glucose metabolism.

    Single-cell transcriptomics of the Drosophila wing disc reveals instructive epithelium-to-myoblast interactions

    Nicholas J Everetts, Melanie I Worley ... Iswar K Hariharan
    A single-cell atlas of the developing Drosophila wing disc at two time points enables a detailed understanding of the signals exchanged between different cell populations during development.

    Quantifying absolute gene expression profiles reveals distinct regulation of central carbon metabolism genes in yeast

    Rosemary Yu, Egor Vorontsov ... Jens Nielsen
    Global gene expression control mechanisms are modeled using a large dataset consisting of absolute-quantitative proteomics, transcriptomics, and partial metabolomics of Saccharomyces cerevisiae at a wide range of growth conditions.

    Topological signatures in regulatory network enable phenotypic heterogeneity in small cell lung cancer

    Lakshya Chauhan, Uday Ram ... Mohit Kumar Jolly
    Network topology and gene expression patterns in small cell lung cancer reveal two mutually opposing teams of regulators that enable multistability and consequent non-genetic heterogeneity, a clinically unsolved challenge.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm, Matthias Platzer ... Philip Dammann
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.
