The Chinese scientist argues that he helped create the world's first genetically engineered babies – twins born this month, whose DNA said he had changed with a powerful new tool capable of re-writing life well.
If true, it would be a profound leap of science and ethics.
The US scientist said he participated in Chinese work, but such genetic modification is banned in the United States, as changes in DNA may pass to future generations and may harm other genes.
Many mainstream scientists think it is too dangerous to try, and some are throwing the Chinese report into human experimentation.
The researcher, he Jiankui Shenzhen, said that he moved embryos to seven couples on fertility treatments, one of which has been pregnancy so far. He said that his goal was not to cure or prevent hereditary disease, but to try to give a characteristic feature that few of them naturally have – the ability to resist possible future infections with HIV, the AIDS virus.
His claim is not an independent confirmation and has not been published in a newspaper in which other experts would check it. She revealed it on Monday [November 26] In Hong Kong, one of the organizers of the International Conference on Gene Editing, which begins on Tuesday and previously in exclusive interviews with The Associated Press.
