For the first time ever, scientists have attempted to cure a person’s disease by editing a gene inside the body.

Scientists used an IV to inject a patient with billions of copies of a corrective gene and a genetic tool to cut his DNA in a specific spot. “We cut your DNA, open it up, insert a gene, stitch it back up.”

Scientists have edited people’s genes in the past, but that work involved altering cells inside a lab and then returning them to the body, whereas the latest experiment was performed inside a person’s body.
