To say CRISPR/Cas9 is every bit as revolutionary as the Internet or the smartphone is an understatement. Scientists are studying applications to fight cancers and it already has been demonstrated the technology can remove HIV from infected human cells. It comes with ethical questions as well for how this technology may benefit humans in the future. The idea of designer babies with reduced diseases linked to faulty genes, or the potential to slow or reverse the aging process may one day be possible using CRISPR/Cas9. Many more human health, animal, and plant applications are being investigated.
