Recently, a Chinese scientist said he created the first genetically modified babies in the world, causing a global storm. If it is true – the scientist still does not publish data that confirms it – his actions would be a serious violation of international scientific conventions. Although genetic modification promises the possibility of correcting dangerous mutations that cause illness and cure certain medical conditions, there are many safety and ethical concerns about the modification of human embryos.
Then we answer some of the many questions that surround this event.
Scientist Han Jianqui claims to have used the "Cryptor", a genetic modification technique to change a gene in human embryos to implant later embryos in the womb of a woman who gave birth to twins in November.
