CRISPR technology could have momentous effects if it's used to edit genes that will be inherited by future generations. Researchers and ethicists continue to weigh appropriate guidelines.
A landmark study in the UK discovered the gene that allows cells to form into embryos. If Australian researchers attempted this they could go to jail for 15 years.
Americans have moved on from worrying about ‘test-tube babies’ – but there are still ethical challenges to resolve as reproductive technologies continue to advance.
A world first study shows CRISPR can remove a target gene from early stage human embryos. But with the advance in science come weighty ethical dilemmas.
