Study on gene-editing tool sparks debate

Editor's Note: Han Chunyu, an associate professor of biology at Hebei University of Science & Technology, impressed researchers across the globe this May with his paper on NgAgo, a new-generation gene-editing tool. Yet several overseas scientists say they have not been able to repeat the experiment and have asked him to publish the original data. Following are the views of two scholars on the issue:
