    Genetic variation, environment and demography intersect to shape Arabidopsis defense metabolite variation across Europe

    Ella Katz, Jia-Jie Li ... Daniel J Kliebenstein
    Measurements of specialized metabolites across a population of 800 natural Arabidopsis thaliana accessions revealed different pressures and evolutionary processes that shaped their variation and distribution across Europe.

    Stability of neocortical synapses across sleep and wake states during the critical period in rats

    Brian A Cary, Gina G Turrigiano
    Sleep and wake states are not sufficient to drive changes in neocortical synaptic strengths.

    Agent-based model demonstrates the impact of nonlinear, complex interactions between cytokines on muscle regeneration

    Megan Haase, Tien Comlekoglu ... Silvia S Blemker
    A computational model of skeletal muscle regeneration reveals complex interplay of cytokines, angiogenesis, and cell behaviors, predicting that synergistic cytokine perturbations enhance skeletal muscle regeneration beyond individual cytokine interventions.

    Multiple serine transposase dimers assemble the transposon-end synaptic complex during IS607-family transposition

    Wenyang Chen, Sridhar Mandali ... Reid C Johnson
    Genetic, structural, and biochemical analyses of IS607-family transposons shows that the DNA translocation reaction proceeds very differently from other reactions promoted by serine recombinases.

    Structural basis for diguanylate cyclase activation by its binding partner in Pseudomonas aeruginosa

    Gukui Chen, Jiashen Zhou ... Haihua Liang
    The diguanylate cyclase activity of SiaD is activated by its binding partner SiaC thourgh a dynamic mechanism of promoting the formation of active SiaD dimers.

    Bacterial lifestyle switch in response to algal metabolites

    Noa Barak-Gavish, Bareket Dassa ... Assaf Vardi
    Opportunistic bacteria modulate their lifestyle from coexistence to pathogenicity by perceiving the physiological state of their algal host through sensing of algal secreted metabolites.

    Measuring ligand-cell surface receptor affinities with axial line-scanning fluorescence correlation spectroscopy

    Antonia Franziska Eckert, Peng Gao ... Gerd Ulrich Nienhaus
    A robust fluorescence microscopy-based data acquisition and analysis framework affords the precise measurement of cell surface receptor affinities toward their cognate ligands and their densities in live cells/tissues.

    Random-sequence genetic oligomer pools display an innate potential for ligation and recombination

    Hannes Mutschler, Alexander I Taylor ... Philipp Holliger
    Random sequence RNA pools display an innate capacity for ligation and recombination, enabling them to “bootstrap” themselves towards higher compositional, informational and structural complexity.

    Structural insights into regulation of CNNM-TRPM7 divalent cation uptake by the small GTPase ARL15

    Luba Mahbub, Guennadi Kozlov ... Kalle Gehring
    ADP-ribosylation factor-like GTPase 15, an atypical small GTPase, binds to cystathionine-β-synthase-pair domain divalent metal cation transport mediator (CNNM) membrane proteins to inhibit divalent cation efflux by CNNM proteins and influx by transient receptor potential ion channel subfamily M member 7.

    Inter-domain dynamics drive cholesterol transport by NPC1 and NPC1L1 proteins

    Piyali Saha, Justin L Shumate ... Suzanne R Pfeffer
    Molecular analysis of cholesterol transport by NPC1 and NPC1L1 proteins reveals that cholesterol likely moves through these transporters, and ezetimibe blocks NPC1L1 by binding at the interface between multiple domains.
