Gene-editing babies: Call to pause humanity-altering research Leading scientists have called for a ban on research to "re-engineer the human species" for the next five years.
Two babies were born last year in China who had been genetically altered to protect them against HIV.
The scientists, writing in the journal Nature, said "major speed bumps" needed to be put in front of such research.
The US National Institutes of Health said a ban should start immediately, but others have criticised the idea. BBC News
