Uncertainties about the cells’ risk profiles and the potential for hyping unproven therapies mean scientists and the media must tread carefully.

A newly expanded genetic alphabet that includes four synthetic nucleotides highlights the need for strict boundaries on their use.

Authors of a new paper take issue with revisions to regulations on biospecimen research enacted last month, and argue that cell lines should be treated differently from other biospecimens.

Multiple researchers were aware of He Jiankui’s clinical trial before the news became public in November.

Researchers edited macaque embryos to induce symptoms of sleep disorders and chose one animal to clone. A bioethicist questions the study’s appropriateness.

He Jiankui could face charges after an investigation finds he used techniques prohibited in China to edit the genes of twin girls.

The documentary weaves together a hunt for mammoth tusks in the Arctic with scenes from the front lines of synthetic biology.

Since He Jiankui presented his results at last week’s gene editing summit, researchers have raised concerns about his protocol, calling the procedure “amateurish” and “unconscionable.”

Despite a premature and ethically sketchy claim of genome editing in twin girls, an outright prohibition could blunt promising, responsible progress.
