The scientist who announced the world's first genome-edited twins received a prison sentence and a large fine for his research. But the systems that enabled him have not been held to account.
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.
Ideas from economics might help us decide the most ethical way of using gene editing technology for human enhancement in the future.
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.
You may not agree with using the gene-editing tool, CRISPR, to alter the DNA of human babies. But what about using it to engineer plants? Or wipe out one of the world's most dangerous creatures?
CRISPR babies may be just the beginning. China has a different take than the West on ethics and how to get ahead in business and other endeavors.
The effort to edit the genes of Chinese twins implies that all our traits are determined by our genes. But changing our diet, environment, lifestyle and microbes may have a greater effect.
Genome editing technology has, and will always have, limits. Limits that are related not to the technology itself but to the intrinsic complexity of the human genome.
To announce the world's first gene-edited babies, scientist He Jiankui did what movie directors do: release a trailer on YouTube. The video is a positive spin on unauthorized gene editing.
Chinese researcher He Jiankui told a spellbound audience how he created gene-edited babies. With a couple of revealing slides, we can see what he did and speculate what health problems might ensue.
