Columbia University scientists have used 'base editing' technology on human embryos for the first time.

Unlike CRISPR, this method changes a single 'letter' of the genetic code without cutting DNA.

The experiment edited three genes: PCSK9, HBG1, and HBG2.

Researchers note the method is not yet ready for clinical use.

Bioethicists warn of potential misuse for genetic enhancement.
