In this issue of Structure, breakthroughs in cryo-EM/ET research are presented. Klebl et al. (2020) demonstrate how speed in sample vitrification impacts the quality of macromolecular particles in resultant cryo-EM grids. Wu et al. (2020) combine fluorescence, ion beam milling, and tomography to unravel unique features in vitrified yeast cells.
