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.
