Scientists have used a transmission electron microscope to record almost 3500 images in 3.5 seconds for the reconstruction of a 3D electron tomogram. Previously, 10 to 60 minutes and a ten-fold greater electron dose were required to record such image sequences. The new capability is particularly suitable for examining cells, bacteria, viruses and dynamic processes, such as chemical reactions and electronic switching phenomena.
