Monkeys cloned from a gene-edited macaque with circadian rhythm disorders are seen at the Chinese Academy of Sciences in Shanghai, China in this handout picture provided by the Institute of Neuroscience of the Chinese Academy of Sciences on January 24, 2019. It was the first time multiple clones had been made from a gene-edited monkey for biomedical research, the agency said. The clones were born at the Institute of Neuroscience at the China Academy of Sciences in Shanghai. Chinese Academy of Sciences/Handout via REUTERS
