    Comparative genomics explains the evolutionary success of reef-forming corals

    Debashish Bhattacharya, Shobhit Agrawal ... Paul G Falkowski
    The analysis of 20 coral genomic datasets provides unprecedented insights into what makes reef-building corals unique, including the evolution of novel gene families involved in biomineralization, signaling and stress responses that have led to their evolutionary success throughout the Phanerozoic Eon.

    Septal cholinergic input to CA2 hippocampal region controls social novelty discrimination via nicotinic receptor-mediated disinhibition

    Domenico Pimpinella, Valentina Mastrorilli ... Marilena Griguoli
    Acetylcholine, released from cholinergic fibers originating from the medial septum, shapes social memory, and controls the CA2 hippocampal circuit via nicotinic receptors localized on GABAergic interneurons.

    Botulinum toxin intoxication requires retrograde transport and membrane translocation at the ER in RenVM neurons

    Jeremy C Yeo, Felicia P Tay ... Frederic Bard
    BoNT intoxication of neurons is revisited using a genome-wide siRNA screen and organelle-specific reporters, suggesting a mechanism of translocation to the cytosol fundamentally different than previously proposed.

    Vein fate determined by flow-based but time-delayed integration of network architecture

    Sophie Marbach, Noah Ziethen ... Karen Alim
    Relative hydraulic resistance, shear rate, and pressure in a vascular network integrate the network's architecture via fluid flow, and determine vein dynamics, with a time delay, in the prototypical organism Physarum polycephalum.

    High-density sampling reveals volume growth in human tumours

    Arman Angaji, Michel Owusu ... Johannes Berg
    Spatial genomics reveals the mode of evolution of a tumour based on the positions of mutations in high-resolution samples.

    An excitatory lateral hypothalamic circuit orchestrating pain behaviors in mice

    Justin N Siemian, Miguel A Arenivar ... Yeka Aponte
    A small population of lateral hypothalamic neurons detects pain and can be activated to suppress pain-related behavioral adaptations and the unpleasantness associated with pain in mice.

    Unraveling the link between neuropathy target esterase NTE/SWS, lysosomal storage diseases, inflammation, abnormal fatty acid metabolism, and leaky brain barrier

    Mariana I Tsap, Andriy S Yatsenko ... Halyna R Shcherbata
    Drosophila model reveals that NTE/SWS-associated neurodegeneration is a lysosomal storage disorder accompanied by a leaky brain permeability barrier, abnormal fatty acid metabolism, and inflammation.

    Fibroblast-derived Hgf controls recruitment and expansion of muscle during morphogenesis of the mammalian diaphragm

    Elizabeth M Sefton, Mirialys Gallardo ... Gabrielle Kardon
    HGF derived from fibroblasts is critical for complete muscularization of the mammalian diaphragm, and loss-of-function experiments reveal that partial muscularization of the diaphragm is not sufficient to cause congenital diaphragmatic hernias.
    1. Chromosomes and Gene Expression

    Oncogene expression from extrachromosomal DNA is driven by copy number amplification and does not require spatial clustering in glioblastoma stem cells

    Karin Purshouse, Elias T Friman ... Wendy A Bickmore
    In glioblastoma stem cells, oncogenes on extrachromosomal DNA do not cluster at distances in keeping with coordinated transcription, with amplified gene expression driven by copy number rather increased transcriptional efficiency.

    Identification and functional characterization of muscle satellite cells in Drosophila

    Dhananjay Chaturvedi, Heinrich Reichert ... K VijayRaghavan
    Modeling adult muscle homeostasis, maintenance and repair will now be possible in Drosophila with the discovery of satellite cells equivalents in flight muscles.
