For the first time, genetically modified human embryos have been developed in the US and Kashmir-born doctor Sanjeev Kaul has played a lead role in this breakthrough.
Scientists have now demonstrated an effective way of using a gene-editing tool to correct a disease-causing gene mutation in human embryos and stop it from passing to future generations.
Though this is not a full-fledged start of a revolution of having 'designer babies', the first steps, however, have been laid. China attempted this earlier.
A team of scientists has altered human embryos using a new technique called CRISPR CAS9 that edits genes and in this case it helped remove a fatal mutation that leads to heart attacks.
This now opens up an ethical 'Pandora's Box' if germline repairs and enhancements may become a thing in vogue.
As of now, the human embryos were not implanted in humans. But this now opens up exciting prospects of the world having designer babies soon.
