In this video from SciTech Now partner Science Friday, a geneticist and a neurobiologist team up in an attempt to cure colorblindness. As the most common genetic disorder worldwide, colorblindness affects roughly 1 in 12 men and 1 in 200 women, the overwhelming majority of whom have trouble perceiving red and green. Using virus-based gene therapy and a group of highly trained monkeys, the scientists may have finally created a cure for the colorblindness blues.
