30 31 Density map (light grey) of the iron storage protein complex from cells, apofferritin, solved by cryo-electron microscopy. The atomic coordinates (dark grey, red, blue, yellow and purple), for the amino acids that make up the protein complex, were then added into the density map in order to better understand its chemistry and function.​ (Image: Daniel Clare) View of the photoemission microscope on beamline I06. At the heart of the picture is where samples are placed in-vacuum for study.​ (Image: Andrew Brookes)
