    An improved organ explant culture method reveals stem cell lineage dynamics in the adult Drosophila intestine

    Marco Marchetti, Chenge Zhang, Bruce A Edgar
    An improved culture method for explanted adult Drosophila organs allows the live-imaging of damage response, cell differentiation, and tracing of progenitor cell lineages through multiple rounds of division.

    Fat2 polarizes the WAVE complex in trans to align cell protrusions for collective migration

    Audrey Miller Williams, Seth Donoughe ... Sally Horne-Badovinac
    Fat2 signals from the trailing edge of each cell to localize WAVE activity to the leading edge of the cell behind, polarizing protrusive regions within cells and across the epithelium.

    Consequences of PDGFRα+ fibroblast reduction in adult murine hearts

    Jill T Kuwabara, Akitoshi Hara ... Michelle D Tallquist
    Cardiac fibroblast reduction is well-tolerated and demonstrates beneficial outcomes after heart injury.

    A feed-forward pathway drives LRRK2 kinase membrane recruitment and activation

    Edmundo G Vides, Ayan Adhikari ... Suzanne R Pfeffer
    Parkinson’s disease-associated LRRK2 kinase is recruited to membranes by its Rab GTPase substrates, and LRRK2 is both retained on membranes and further activated there by cooperative interaction with the phosphorylated Rab proteins that it generates.

    Telocytes regulate macrophages in periodontal disease

    Jing Zhao, Anahid A Birjandi ... Paul Sharpe
    A poorly understood cell type, the telocyte, is shown to regulate macrophages.

    Balance between breadth and depth in human many-alternative decisions

    Alice Vidal, Salvador Soto-Faraco, Rubén Moreno-Bote
    A novel experimental paradigm investigating how humans manage limited search capacity over many alternatives reveals close-to-optimal behaviours and identifies heuristics used to minimize computation with little impact on performance.

    Genetically predicted high IGF-1 levels showed protective effects on COVID-19 susceptibility and hospitalization: a Mendelian randomisation study with data from 60 studies across 25 countries

    Xinxuan Li, Yajing Zhou ... Xue Li
    Genetically predicted high insulin-like growth factor levels may decrease the risk of COVID-19 susceptibility and hospitalization.

    Fat body phospholipid state dictates hunger-driven feeding behavior

    Kevin P Kelly, Mroj Alassaf ... Akhila Rajan
    Behavioral, lipidomic, and genetic analyses of adult Drosophila on a chronic high-sugar regime identified that fat body activity of a phospholipid biosynthesis enzyme, Pect, regulates insulin sensitivity and hunger response.

    The SPARC complex defines RNAPII promoters in Trypanosoma brucei

    Desislava P Staneva, Stefan Bresson ... Robin C Allshire
    The SPARC complex directs accurate RNAPII positioning for transcription initiation and, in some instances, ensures correct transcription directionality in Trypanosoma brucei.

    Zbtb14 regulates monocyte and macrophage development through inhibiting pu.1 expression in zebrafish

    Yun Deng, Haihong Wang ... Jun Zhu
    Transcription factor Zbtb14 plays an important role in monocyte and macrophage development through the modulation of pu.1 expression.
