China draws up tighter rules on human gene and embryo trials: Xinhua

He Jiankui, associate professor at Southern University of Science and Technology in Shenzhen, attracted condemnation from the global scientific community when he said he had used a technology known as CRISPR-Cas9 to alter the embryonic genes of twin girls born in November.
