Two academic journals published in the journal and negative gene editing technology NgAgo with gene editing capabilities have renewed the controversy surrounding Han Chunyu, an associate professor at Hebei University of Science and Technology. After more than three months, Nature once again reported Han Chunyu and his NgAgo in an academic whirlpool.
On the evening of November 23, Beijing time, in this report entitled "NgAgo Gene Editing Controversy in the Peer Review Paper", Han Chunyu, who disclosed NgAgo's initial effective anonymous scientist, author of academic communication, published academic newsletter The journal editors, foreign scientists who thought that NgAgo was ineffective, and the journal Nature-Biotechnology, which published Han Chunyu's thesis, made a sound.
Han Chunyu told Nature that he has discovered a problem that may be overlooked by others but can be used to explain why it is difficult to repeat his experiments. Han Chunyu said that he is working on confirmation to ensure that the published experimental operations and data will satisfy the critics. "I can't say it now because the Chinese media criticized anything I said." Han Chunyu attributed the media to the media. "I need a little time."

In another Nature report published in August, an independent third-party Chinese scientist said that although not efficient, NgAgo can edit on some cells, and two Chinese scientists who asked for anonymity said they The initial results showed that NgAgo was effective, but further sequencing confirmation was needed.
In the latest "Nature" report, two of them updated their own dynamics, one said that they are using NgAgo for other experiments, hoping to publish as soon as possible, and the other said "data is confusing", "we Can't draw a conclusion."
It is worth mentioning that Han Chunyu said in an interview that he had provided a list of five people for the interview of David Cyranoski, the author of the two reports, "Nature" correspondent, who was believed by Han Chunyu to prove him. The experiment is effective. I have confirmed this to David Cyranoski.
The one that triggered Nature’s refocusing on the report was, to a certain extent, two academic newsletters. On November 16th, the heads of 20 laboratories from home and abroad jointly wrote the article "Questions about NgAgo" ("Questions about NgAgo"), published online in the domestic journal "Protein & Cell". on. Eight laboratories tried many times, and completely referred to the operations written in Han Chunyu's paper, using the experimental materials provided by Han Chunyu, which did not change the negative results of NgAgo.
