West et al. use electron tomography to reconstruct the 3D organization of the ER in budding yeast and identify three peripheral ER domains: tubular ER (green), central cisternal ER (yellow) and plasma membrane–associated ER (blue). The image superimposes two separate tomograms from yeast with different bud diameters to demonstrate the ER domains’ distributions during inheritance. The nuclear envelope is colored orange, the Golgi purple, and vesicles pink and white.

Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in the cytosol or within a membrane-bound vacuole. Credit: NIAID
