    Cell cycle entry triggers a switch between two modes of Cdc42 activation during yeast polarization

    Kristen Witte et al.
    Optogenetic control of Cdc42 activation during polarization of budding yeast demonstrates a cell cycle regulated switch between two distinct modes of positive feedback.

    Rac1 GTPase activates the WAVE regulatory complex through two distinct binding sites

    Baoyu Chen et al.
    The cryo-electron microscopy structure of an assembly of the WAVE Regulatory Complex and its activator, the Rac GTPase, plus complementary biochemistry and biophysics, reveal a novel activation mechanism involving two distinct Rac binding sites.

    In vivo identification of GTPase interactors by mitochondrial relocalization and proximity biotinylation

    Alison K Gillingham et al.
    Relocation of Rab, Ras and Rho family GTPases to the surface of mitochondria enables efficient identification of their effectors, exchange factors and GAPs by proximity biotinylation.

    Experimental and observational studies find contrasting responses of soil nutrients to climate change

    ZY Yuan et al.
    Experimental manipulations and environmental gradients, the two common-used approaches, are not at all comparable for predicting the impacts of climate change on nutrient cycling.

    Protein-mediated RNA folding governs sequence-specific interactions between rotavirus genome segments

    Alexander Borodavka et al.
    In rotaviruses, the selective packaging of eleven distinct genomic RNA segments requires virus-encoded protein NSP2 to alter the RNA structures, facilitating their interactions with each other.
