X-rays emerge from a synchrotron to hit a protein-covered substrate. From the film, proteins emerge, which are aggregated into football-like nanoparticles, as described by A. A. Gorodetsky and co-workers on page 8405. The protein and the nanoparticles are present in cephalopod skin; these cells emerge from a purple squid and underpin its camouflage abilities.
