The gene-editing tool CRISPR has been used for the first time inside the body of an adult, in an attempt to cure a form of blindness.
The treatment: According to the Associated Press, doctors dripped just a few drops of a gene-editing mixture beneath the retina of a patient in Oregon who suffers from Leber congenital amaurosis, a rare inherited disease that leads to progressive vision loss.
Cells that take up the mixture can have their DNA permanently corrected, potentially restoring a degree of vision.
