Take a deep dive into one of the most awe-inspiring medical innovations of our time: gene therapy. It's comparable to some of the greatest scientific explorations ever undertaken. Like landing astronauts on the moon or sending spacecraft toward the edges of our galaxy. Except, instead of probing the vastness of outer space, this season, we’ll explore the infinite universe inside the tiny molecules of our DNA, and look at medical technology with the potential to reshape our approach to treating many genetic diseases.Thousands of lives could be saved and countless more changed with gene therapy.
