HONG KONG – Chinese researcher claims that he helped the first genetically edited baby world – twin girls born this month that his DNA said to alter b & # 39; new tool b & # 39; robust that it can & # 39; re & # 39; write the same plane & # 39; life.

If true, would be a major step & # 39; science and ethics.

The scientist & # 39; the US said it took part in the work in China, but this kind of & # 39; gene editing is banned in the US because the DNA changes can pass to future generations and this could jeopardize other genes.

Many mainstream scientists think that not much good to try, and some iddenunzjaw the Chinese report as human experimentation.

The researcher, is Jiankui of & # 39; Shenzhen, said he changed seven embryos & # 39; while couples treatments & # 39; fertility, b & # 39; one turned up windows now.

It werah Monday in & # 39; Hong Kong to one of the organizers of & # 39; international conference on gene editing to start Tuesday, and before f & # 39; exclusive interviews with & # 39; The Associated Press.

"I feel a strong responsibility to not only do the first, but also make an example", told the AP. "Society will decide x & # 39; must be preceded by" f & # 39; & # 39 terms of a permit or ban & # 39; this science.
