    Three-dimensional structure of kinetochore-fibers in human mitotic spindles

    Robert Kiewisz, Gunar Fabig ... Thomas Müller-Reichert
    Comprehensive 3D electron tomography reconstructions of metaphase spindles in human tissue culture cells reveal that kinetochore-fibers broaden as they extend polewards, forming semi-direct connections to the pole, where they preferentially interact with the spindle network.

    Oligodendrocytes control potassium accumulation in white matter and seizure susceptibility

    Valerie A Larson, Yevgeniya Mironova ... Dwight E Bergles
    Oligodendrocytes in white matter use Kir4.1 inwardly rectifying potassium channels to prevent extracellular potassium accumulation, enabling neurons to sustain repetitive firing and limiting the initiation of seizures.

    Distinct gating mechanisms revealed by the structures of a multi-ligand gated K+ channel

    Chunguang Kong, Weizhong Zeng ... Youxing Jiang
    Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

    Profound regulation of Na/K pump activity by transient elevations of cytoplasmic calcium in murine cardiac myocytes

    Fang-Min Lu, Christine Deisl, Donald W Hilgemann
    Transient Ca elevations of cytoplasmic calcium in cardiac myocytes profoundly activate cardiac Na/K pump activity in parallel with physical-chemical changes of the sarcolemma but without involvement of conventional signaling mechanisms.

    The molecular basis for an allosteric inhibition of K+-flux gating in K2P channels

    Susanne Rinné, Aytug K Kiper ... Niels Decher
    A combined systematic alanine scanning and molecular modelling approach reveals the molecular basis for an allosteric inhibition mechanism of K+-flux gating in K2P channels.

    Association mapping from sequencing reads using k-mers

    Atif Rahman, Ingileif Hallgrímsdóttir ... Lior Pachter
    Associations can be mapped using k-mer frequencies in sequencing reads without prior sequencing of a reference genome enabling detection of associations to variants of multiple types and outside of the reference.

    KCNE1 tunes the sensitivity of KV7.1 to polyunsaturated fatty acids by moving turret residues close to the binding site

    Johan E Larsson, H Peter Larsson, Sara I Liin
    An auxiliary subunit alters the effect of a family of small-molecule openers on a voltage-gated potassium channel by inducing structural re-arrangements that promote protonation of the drug molecule.

    Kinetochore-fiber lengths are maintained locally but coordinated globally by poles in the mammalian spindle

    Manuela Richter, Lila Neahring ... Sophie Dumont
    Live imaging and physical perturbations of spindles with unfocused poles reveal that mammalian spindle length emerges locally from kinetochore-fibers, but that global cues from focused spindle poles are needed to coordinate k-fibers across space and time and accurately segregate chromosomes.

    Environmental fluctuations reshape an unexpected diversity-disturbance relationship in a microbial community

    Christopher P Mancuso, Hyunseok Lee ... Ahmad S Khalil
    Laboratory experiments using a microbial community and mathematical modeling reveal how environmental disturbances can predictably alter the diversity and composition of an ecosystem.

    Signaling pathways as linear transmitters

    Harry Nunns, Lea Goentoro
    Mathematical and experimental analyses suggest that despite their complex architectures, multiple metazoan signaling pathways act in physiological contexts as linear signal transmitters.
