    Structured illumination with particle averaging reveals novel roles for yeast centrosome components during duplication

    Shannon Burns, Jennifer S Avena ... Sue L Jaspersen
    Visualization of yeast spindle pole proteins using a new microscopy method shows that assembly into the nuclear membrane occurs at the same time as duplication.

    Structure and in situ organisation of the Pyrococcus furiosus archaellum machinery

    Bertram Daum, Janet Vonck ... Werner Kühlbrandt
    Using both electron cryo-tomography and helical reconstruction, the first structure of the entire archaellum machinery with an assembled filament has been determined, providing the structural basis for our understanding of archaeal motility.

    Routine single particle CryoEM sample and grid characterization by tomography

    Alex J Noble, Venkata P Dandey ... Bridget Carragher
    Fiducial-less tomography on single particle cryoEM samples reveals that most particles are adsorbed to the air-water interface and allows for researchers to diagnose and solve sample, grid, ice thickness, collection, and processing issues.

    Deciphering anomalous heterogeneous intracellular transport with neural networks

    Daniel Han, Nickolay Korabel ... Thomas A Waigh
    Direct estimation of the Hurst exponent shows that endosomes and lysosomes reside in regimes of persistent and anti-persistent motion with heavy-tailed residence time distributions and motion correlated with endocytic function.

    Cryo-EM structure of the KvAP channel reveals a non-domain-swapped voltage sensor topology

    Xiao Tao, Roderick MacKinnon
    The structure of KvAP addresses a mechanism of voltage-dependent gating that has been debated for 16 years.

    New approach for membrane protein reconstitution into peptidiscs and basis for their adaptability to different proteins

    Gabriella Angiulli, Harveer Singh Dhupar ... Thomas Walz
    Cryo-EM structures reveal how the peptidisc scaffold can adapt to different membrane proteins, establishing it as a universal membrane mimetic to stabilize membrane proteins in solution.
