After the controversy of a Chinese scientist who was involved in editing the genomes of twin girls, the country puts forth tighter guidelines.

Two studies show signs that the introduced DNA is functioning, but it’s too early to know if patients actually benefit.

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

2018 closed with hubbub surrounding the purported birth of babies whose genomes had been edited using CRISPR. What will 2019 hold for CRISPR’s use in humans?

He Jiankui says he has successfully used CRISPR-Cas9 to tweak the genes of twins born earlier this month. Some independent experts are dubious.

With a built-in supply of a powerful cocaine-chomping enzyme, the transplant might also curb addiction.

The UK-based organization encourages public debate about the issue but does not recommend immediate policy change.

Brief electroporation appears to make T cells more receptive to new genetic material, which could speed the development of immunotherapies.

US researchers could become the first outside China to use the gene-editing technique in the clinic.
