    Chronic postnatal chemogenetic activation of forebrain excitatory neurons evokes persistent changes in mood behavior

    Sthitapranjya Pati, Kamal Saba ... Vidita A Vaidya
    Enhanced Gq-signaling-mediated activation of forebrain excitatory neurons in postnatal life programs enhanced anxiety-, despair- and schizophrenia-like behavior, recapitulating key aspects of the behavioral consequences of early life adversity.

    Evolution of multicellularity by collective integration of spatial information

    Enrico Sandro Colizzi, Renske MA Vroomans, Roeland MH Merks
    Selection for undifferentiated multicellularity emerges in an evolutionary cell-based model because a collective of cells performs chemotaxis better than single cells in a noisy environment.

    A single mutation in Crimean-Congo hemorrhagic fever virus discovered in ticks impairs infectivity in human cells

    Brian L Hua, Florine EM Scholte ... Éric Bergeron
    Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.

    Functional exploration of heterotrimeric kinesin-II in IFT and ciliary length control in Chlamydomonas

    Shufen Li, Kirsty Y Wan ... Junmin Pan
    Experimental and modelling analyses suggest a non-linear scaling relationship between IFT velocity and ciliary length that can be accounted for by limitation of the motors.

    A natural variant of the essential host gene MMS21 restricts the parasitic 2-micron plasmid in Saccharomyces cerevisiae

    Michelle Hays, Janet M Young ... Harmit S Malik
    A novel assay to measure 2-micron stability together with a survey of natural variation among Saccharomyces cerevisiae strains reveals novel means by which yeasts can combat the parasitic 2-micron plasmids.

    Structural basis of ClpXP recognition and unfolding of ssrA-tagged substrates

    Xue Fei, Tristan A Bell ... Robert T Sauer
    Cryo-EM structures of the AAA+ ClpXP protease bound to an ssrA degron reveal the mechanism of substrate recognition and show how the machine transitions from recognition to translocation and unfolding.

    Weight loss, insulin resistance, and study design confound results in a meta-analysis of animal models of fatty liver

    Harriet Hunter, Dana de Gracia Hahn ... Jake P Mann
    Animal studies of fatty liver disease over-estimate the benefit of drugs due to publication bias and are confounded by off-target weight loss, illustrating the challenge of successful translational across species.

    Molecular evidence of hybridization between pig and human Ascaris indicates an interbred species complex infecting humans

    Alice Easton, Shenghan Gao ... Thomas B Nutman
    Comparative phylogenomic analyses based on a new reference-quality human Ascaris genome assembly reveals a pig/human interbred species complex with implications for Ascaris control worldwide.

    Arrayed CRISPRi and quantitative imaging describe the morphotypic landscape of essential mycobacterial genes

    Timothy J de Wet, Kristy R Winkler ... Digby F Warner
    A high-throughput functional genomics approach combining inducible CRISPR-interference and quantitative imaging yields an atlas of 'phenoprints' to guide gene function assignments, identify metabolic pathway-specific morphotypes, and inform antibiotic mechanism-of-action studies.

    Modulation of flight and feeding behaviours requires presynaptic IP3Rs in dopaminergic neurons

    Anamika Sharma, Gaiti Hasan
    Motivation for flight and feeding behaviour requires dopamine release which depends on cholinergic stimulation and intracellular Ca2+ release from ER stores in one or two pairs of central dopaminergic neurons.
