It’s Midday on Ethics with Dr. Jeffrey Kahn of the Johns Hopkins Berman Institute of Bioethics.Today we’ll explore some of the ethical issues raised by the explosive case of a Chinese researcher named He Jiankui. In late November, He announced the birth of twin girls, Lulu and Nana, who, he says, are the world’s first gene-edited humans. Most countries, including China, ban human gene editing, and scientists around the world have strongly denounced He’s shocking claims, which raise ethical questions not only for the newborns, but for future generations.We live-streamed this conversation on WYPR's Facebook page.
