    Intracellular functions and motile properties of bi-directional kinesin-5 Cin8 are regulated by neck linker docking

    Alina Goldstein-Levitin, Himanshu Pandey ... Larisa Gheber
    Precise hydrogen-bond stabilization of the neck linker docking onto the catalytic motor domain, is crucial for motor activity and intracellular functions of the bi-directional mitotic kinesin-5 Cin8.

    Super-resolution kinetochore tracking reveals the mechanisms of human sister kinetochore directional switching

    Nigel J Burroughs, Edward F Harry, Andrew D McAinsh
    Directional switching of sister chromatids during mitosis is regulated by a mechanical clock that is sensitive to the stretch of centromeric chromatin between the chromatids.

    Origin and role of the cerebrospinal fluid bidirectional flow in the central canal

    Olivier Thouvenin, Ludovic Keiser ... Claire Wyart
    The combination of data and modelling shows the mechanisms underlying bidirectional flow of cerebrospinal fluid and its impact on long range transport in the CSF between brain and spinal cord.

    Genetic mechanisms control the linear scaling between related cortical primary and higher order sensory areas

    Andreas Zembrzycki, Adam M Stocker ... Dennis DM O'Leary
    Primary and higher order visual area dimensions in the neocortex are determined by the same genetic mechanisms during development which in turn also control the proportionate scaling between them.

    Age- and diet-associated metabolome remodeling characterizes the aging process driven by damage accumulation

    Andrei S Avanesov, Siming Ma ... Vadim N Gladyshev
    Aging is a process characterized by gradual metabolome remodeling, deceleration of the remodeling in late life and under conditions that extend lifespan, and a mortality-associated pattern of cumulative damage.

    Coincidence detection and bi-directional transmembrane signaling control a bacterial second messenger receptor

    Richard B Cooley, John P O’Donnell, Holger Sondermann
    Building on previous work (Chatterjee et al., 2014), the mechanism of coincidence detection in bacterial second messenger signaling across membranes is revealed at a molecular level, providing insight into the regulation of a conserved transmembrane receptor.

    Formin-2 drives polymerisation of actin filaments enabling segregation of apicoplasts and cytokinesis in Plasmodium falciparum

    Johannes Felix Stortz, Mario Del Rosario ... Sujaan Das
    Formin-2 controls spatiotemporal polymerisation of actin filaments, a common mechanism used by apicomplexans for effective segregation of essential chloroplast-like organelles called apicoplasts, and additionally for daughter formation in Plasmodium falciparum.

    Firing rate adaptation affords place cell theta sweeps, phase precession, and procession

    Tianhao Chu, Zilong Ji ... Si Wu
    Adaptation within a continuous attractor neural network explains theta phase precession and procession, providing insight into the neural mechanism of theta phase coding in the hippocampus.
