On October 8th, when he saw Han Chunyu again in the laboratory of Hebei University of Science and Technology, although he was in the controversy vortex of "paper falsification" and "multiple people repeated experiment failure", he looked very calm and still talked about it. From time to time, I asked the reporter: "Do you think that if I am fraudulent, can I still be so calm?" He said that some people said on the Internet, how can Han Chunyu sleep now? "I tell you, I slept very well."
On the afternoon of the same day, the Science and Technology Daily reporter conducted an exclusive interview with Han Chunyu in Shijiazhuang. The following is an interview record:
Some labs now say that you can't repeat your experiment. What do you think about this problem?
Han Chunyu: I am also studying why others have repeated experiment failures, but there is no scientific conclusion. I can say some reasons for speculation in private. For example, it may be material pollution, but the scientific conclusion will wait for some time.
Have you repeated this experiment yourself?
Han Chunyu: Of course, the experiment was repeated as required before the publication of the paper, and it was repeated after the paper was published.
Then why not set up a 360-degree camera and repeat the experiment in a monitoring environment?
Han Chunyu: This is a guilty inference, I don't think it is necessary. Japan’s Xiao Baofang Haruko has not repeated a laboratory, and my experiment has been repeated. Even the journalist David of Nature has investigated it. Why should I self-certify and be sick?
(Note: Nature Cycling Asia Pacific correspondent David Cyranoski wrote a report in August this year, the article said: interviewed three anonymous Chinese researchers, one of them said that several cell lines detected the NgAgo system, and the results show that NgAgo can The genetic mutation was induced at the expected site, but the efficiency of the NgAgo system was not higher than that of CRISPR-Cas9, and may be further improved. Two other scientists who requested anonymity said that some preliminary results showed that NgAgo was effective. However, it still needs further sequencing to confirm. But afterwards, Nature and David both said that the report could not be used as a repeatable evidence for Han Chunyu's experiment.)
"Nature" later issued a statement saying that the reporter's report could not represent the results of the magazine's investigation. In addition, the three people mentioned in the "Nature" report are anonymous. Do you think it can be used as an experimentally repeatable evidence?
Han Chunyu: If you say that the report cannot be used as evidence, those who question my report are used as evidence of my fraud. "Nature" reporter David is very professional. I provided a list of 5 people to him. Finally, he interviewed 3 of them, but the other party asked for anonymity. David’s report is why I’m ignoring why everyone’s ignorance, blindly pursuing reports that question me, and always saying “many people can’t repeatâ€.
