Molecular architectures of centrosomes in C. elegans embryos visualized by cryo-electron tomography
Tollervey et al. use cryo-electron tomography to capture 3D snapshots of centrosomes at molecular resolution in their near-native state inside embryonic C. elegans cells in different stages of cell division. They characterize structural features of centrioles during their assembly and of a disordered matrix that nucleates and organizes mitotic spindle microtubules.

Nuclear pore permeability and fluid flow are modulated by its dilation state
Hoffmann et al. describe within cells how the Dictyostelium discoideum nuclear pore complex structure constricts and dilates as a consequence of osmotic stress. Based on their experimental findings, they propose a hydrodynamics model and quantify fluid flow across nuclear pore complexes under conditions when nuclei change their volume rapidly.
