A number of things may have gone wrong when researchers edited Chinese twins Lulu and Nana's genome. Either way, the failed experiment is a cautionary tale for us all.
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.
The genes in our cells' mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn't derailed by mutations.
A new gene editing experiment explores human development. With this comes new ethical questions: How do scientists acquire embryos and how are their projects approved?
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.
A team in the U.S. is said to have safely and effectively altered human embryos. The news is a reminder that citizens must be consulted on developments potentially affecting the future of the species.
The news may have come as a surprise, but it probably shouldn't have. A bioethics expert walks through how big a deal this announcement is – and what we should be considering now.
A new evolutionary perspective on what's been a medical paradox: Why does the body use inflammation to regulate aspects of pregnancy when inflammation is also a big threat to pregnancy?
Stem-cell scientists have to work within many limitations placed on their research. One of these is the 14-day rule that outlaws research on pure human embryos over two weeks old.
While gene editing offers the exciting potential for disease therapies, using it on human embryos opens up a can of worms.
