The first genetically gene-edited babies: It's "irresponsible and too early".

A scientist, Jiankui He of Southern University of Science and Technology of China, recently claimed at the Second International Summit on Human Genome Editing in Hong Kong on 29 November that he has created the world's first genetically altered babies using CRISPR. This announcement sparked controversy and criticism. The newly developed CRISPR/Cas9 technique has been applied to genetic modification of many kinds of animals. However, the technique is still in its infancy and many questions remain to be answered before it can be used for clinical purposes, especially for reproductive purposes.
