Ancient gene therapy
Procedure developed by Dr. Carson Beckett in which a human without the Ancient gene can receive a retrovirus which allows them to use Ancient technology. The project was underway months before Beckett took his research with him into the Pegasus Galaxy.
In the therapy, a mouse retrovirus is used to deliver the missing gene directly to the cells. This permits the user to initiate Ancient technology and run more sensitive equipment, such as a Puddle Jumper.
It is not known how long the therapy lasts, if an individual user requires repeated treatments, or if it is permanent.
