    Overtone focusing in biphonic tuvan throat singing

    Christopher Bergevin et al.
    In light of the mysteries underlying the biphonic nature of Tuvan throat song, information from multiple modalities is combined to explain how this remarkable phenomenon is achieved biomechanically.

    High-throughput, single-particle tracking reveals nested membrane domains that dictate KRasG12D diffusion and trafficking

    Yerim Lee et al.
    The nanoscopic landscape of the membrane has a direct impact on the spatiotemporal, and likely also the signaling, dynamics of Ras proteins.

    Membrane interactions of the globular domain and the hypervariable region of KRAS4b define its unique diffusion behavior

    Debanjan Goswami et al.
    Compared to other isoforms of RAS, KRAS4b has unique membrane diffusion behavior related to its biology, and the two major domains of the protein both contribute to this diffusion behavior.

    Principles of self-organization and load adaptation by the actin cytoskeleton during clathrin-mediated endocytosis

    Matthew Akamatsu et al.
    An experimentally constrained multiscale mathematical model predicts that branched actin networks self-organize at endocytic sites and bend to produce force, which was verified with cryo-electron tomography of intact cells.

    High-speed motility originates from cooperatively pushing and pulling flagella bundles in bilophotrichous bacteria

    Klaas Bente et al.
    Bacteria reach swimming speeds of several hundred body lengths per second and change direction in less than 5 ms by using coordinated flagella bundle agitation.
