    Functional ultrasound imaging of stroke in awake rats

    Clément Brunner, Gabriel Montaldo, Alan Urban
    Functional ultrasound imaging was used to monitor brain hemodynamics and sensory-evoked thalamocortical functions in awake rats pre- and post-stroke, advancing our understanding toward new therapeutic developments.

    Proximity labeling of protein complexes and cell-type-specific organellar proteomes in Arabidopsis enabled by TurboID

    Andrea Mair, Shou-Ling Xu ... Dominique C Bergmann
    Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.

    Choice history biases subsequent evidence accumulation

    Anne E Urai, Jan Willem de Gee ... Tobias H Donner
    Choice history signals bias the interpretation of current sensory input, akin to shifting endogenous attention toward (or away from) the previously selected interpretation.

    A regulatory microRNA network controls endothelial cell phenotypic switch during sprouting angiogenesis

    Stefania Rosano, Davide Corà ... Alessio Noghero
    Coordinated microRNAs activity induced by VEGF represses cell proliferation and favors cell migration at the onset of sprouting angiogenesis in endothelial cells.

    High-resolution, genome-wide mapping of positive supercoiling in chromosomes

    Monica S Guo, Ryo Kawamura ... Michael T Laub
    GapR-seq enables the global mapping of positive supercoiling in bacteria and yeast, revealing positive supercoils downstream of highly expressed genes and, in yeast, associated with centromeres, pericentromeres, telomeres, replication origins, and R-loops.

    Convergent organization of aberrant MYB complex controls oncogenic gene expression in acute myeloid leukemia

    Sumiko Takao, Lauren Forbes ... Alex Kentsis
    Definition of leukemia gene expression mechanisms reveals general principles of cancer gene control and offers a pharmacologic strategy for its therapeutic reprogramming.
    1. Computational and Systems Biology

    Gene regulatory network reconstruction using single-cell RNA sequencing of barcoded genotypes in diverse environments

    Christopher A Jackson, Dayanne M Castro ... David Gresham
    Single cell expression data can be used to determine how regulatory transcription factors and target genes are connected, and is especially useful when studying transcription factors controlling heterogeneous cell states.

    Dynamic modes of Notch transcription hubs conferring memory and stochastic activation revealed by live imaging the co-activator Mastermind

    F Javier DeHaro-Arbona, Charalambos Roussos ... Sarah Bray
    Live imaging of the Notch co-activator Mastermind reveals that it promotes the formation of a dynamic transcription hub in Notch ON nuclei, conferring probabilistic transcription and providing a template for signal memory.

    A Notch-dependent transcriptional mechanism controls expression of temporal patterning factors in Drosophila medulla

    Alokananda Ray, Xin Li
    Cell-cycle-dependent Notch signaling cooperates with temporal transcription factors to promote the progression of the temporal transcription factor cascade in Drosophila medulla neuroblasts.
