Chinese scientist He Jiankui on Wednesday justified the first genetically modified children's books in the world created without some institutional support and announced that another woman was pregnant with an embryo, whose genes were also changed.
The scientist was already announced tomorrow that he had used the bilingual CRISPR / Cas9 technique to make two resistant to diseases such as HIV, a revelation that controversy and doubts of both the audience and the scientific community in and outside China has got.

The scholar had proposed plans to participate in a symposium on & # 39; The Human Genome Edition at Hong Kong University, today's academic and media interest in # 39; the university camp was held there the conference.
"The study has given effective results and is provided for feedback" to the scientific community, He said.
The geneticist recognized that his experiment was not set up by an official institution – said the age genetic acting twin, Lulu and Nana, "were born healthy and happy" by in vitro fertilization with genetic modification technology "HIV is infected."
He then announced that he paused in his clinical problems, "caused by the controversy" that have arisen.
"All the experiments are due to the suffering of the news about my studies," he said, "before or expected," while the moderator of conference, Robin Lovell-Badge, confirmed that the organizers nothing of & # 39; the experiment
The scientist was "proud" of the use of the CRISPR / Cas9 gene editing technique and claims that the study did not aim to prevent genetic disease, but to give girls the natural capabilities to make a possible future control HIV infection.
"Although there has been a benefit in HIV treatments, new infections remain a problem for many countries, especially the least developed," he said.
He said he had experimented with seven couples, affiliated with one of their members with HIV and announced that there is at least one pregnancy between their "in the earliest phase" and others more "possible".
"We have worked with seven pairs, whereas the male is a carrier of the AIDS virus and the woman is not," he said, and indicated that he had visited eleven embryos in six implants.
In a previous way he indicated that he even financed the experiment that "it was not disappeared secretly" and that he had the message to scientists from China, the United States and the United Kingdom, although he does not mention any names.
"There are people who have helped and we have the technology," he said, parents were informed about the risk that they were experimentally involved and their agreement to see.
He also thanked at the University of Science and Technology of South of # 39; the city of Shenzhen, where he had "himself," if he did not know "what he was.
On Monday, the same university has announced that the scientist has investigated and said they were "deeply shocked by the case", which they described as "a serious loss of ethics and academic standards."
The Chinese authorities, on the other hand, have known today that they are "very worried" about the case, where they will address "serious" if they explain it.
Chinese Minister of Science and Technology, Xu Nanping, has the concern that China in vitro research into human embryonic stone cells is limited to a maximum of 14 days in line with ethical guidelines published in 2003.
More than 120 scholars of Chinese scientists say Monday in a statement by Sina Weibo, the Chinese equity of Twitter, that "any attempt" to make changes in human embryos through genetic changes is "scary" and that gives Light for these babies contributes "a high risk".
International has drafted Natuurblêd in Monday's debate on Monday and stated that the announcement has "resign" under the international scientific community and that, as it were, "would be a significant ship in the use of human genomode modification".
Nature has shown that this type of tool was only used to examine its benefits in eliminating disease-changing mutations, adding that the scientific community "has long asked" the creation of ethical guidelines for a long time A sack would this occur.
