Say hello to cloned monkeys

摘要

MEET Zhong Zhong and Hua Hua, the world's first monkeys cloned using the technique that gave us Dolly the sheep. The female long-tailed macaques represent a technical milestone. It should make it possible to create customisable and genetically uniform populations of monkeys, which could speed up treatments for diseases such as Parkinson's, Alzheimer's and cancer. But the breakthrough will inevitably raise fears that human cloning is closer than ever.
