Caption: Professor of mechanical engineering Xiaochun Li (left) and research assistant Hongseok Choi use a cold laser to cut slices of American cheese into computer-generated shapes such as a Christmas tree and Bucky Badger. Unlike conventional lasers that would burn food products, the new process developed by Li and Choi uses a higher-energy UV laser, which severs the bonds between molecules in a process called photoablation.
