Embryo editing ‘breakthrough’ raises spectre of designer babies
Scientists have raised the spectre of designer babies once again, after researchers successfully removed DNA which causes a heart defect from human embryos for the first time.
Using a technique known as Crispr-Cas9, scientists from the US and South Korea removed DNA which causes hypertrophic cardiomyopathy from 58 embryos and allowed them to develop for a further five days.
At the end of the controversial experiment, one in four embryos had re-developed the problem DNA. All of the embryos were destroyed afterwards....
