    Gut bacterial aggregates as living gels

    Brandon H Schlomann, Raghuveer Parthasarathy
    A theory of gut bacterial aggregation produces a cluster size distribution that matches that of several strains observed in zebrafish, suggesting principles generally applicable to the vertebrate gut.

    A modified fluctuation assay reveals a natural mutator phenotype that drives mutation spectrum variation within Saccharomyces cerevisiae

    Pengyao Jiang et al.
    Certain mutational signatures vary in their contribution to genetic variation across the yeast phylogeny due to genetically encoded natural mutator phenotypes whose activity can be directly measured in the lab.

    Activity-dependent Golgi satellite formation in dendrites reshapes the neuronal surface glycoproteome

    Anitha P Govind et al.
    Neuronal activity triggers the dispersal of the Golgi into dendritic Golgi satellites, leading to reshaping of the neuronal surface glycoproteome through processing of glycans to mature, sialic acid-containing forms.

    Physiology and ecology combine to determine host and vector importance for Ross River virus

    Morgan P Kain et al.
    The role host and vector species play in pathogen transmission cycles is best quantified by integrating species' physiological and ecological competence.

    The whale shark genome reveals patterns of vertebrate gene family evolution

    Milton Tan et al.
    The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.

    An essential, kinetoplastid-specific GDP-Fuc: β-D-Gal α-1,2-fucosyltransferase is located in the mitochondrion of Trypanosoma brucei

    Giulia Bandini et al.
    The activity, localization, and essentiality of TbFUT1, together with its ability to complement Leishmania parasites lacking the homologous gene, suggest the presence of an uncommon and conserved mitochondrial fucosylation pathway required for kinetoplastid parasites viability.

    Dynamically linking influenza virus infection kinetics, lung injury, inflammation, and disease severity

    Margaret A Myers et al.
    Important nonlinear links between infection, inflammation, and disease severity were revealed using experimentally validated mathematical models.

    Image3C, a multimodal image-based and label-independent integrative method for single-cell analysis

    Alice Accorsi et al.
    Image3C is a new image-based analysis of cell population composition for research organisms in which detailed cellular phenotypes are unknown or for which species-specific reagents are not available.

    In vivo analysis reveals that ATP-hydrolysis couples remodeling to SWI/SNF release from chromatin

    Ben C Tilly et al.
    Visualization of BRM remodelers engaging their endogenous genomic targets revealed highly transient and dynamic interactions with chromatin, which are fueled by ATP-hydrolysis.
