It has been hailed as the most significant discovery in biology since polymerase chain reaction allowed for the mass replication of DNA samples. CRISPR-Cas9 is an inexpensive and easy-to-use gene-editing method that promises applications ranging from medicine to industrial agriculture to biofuels. Currently, applications to treat leukemia, HIV, and cancer areunder experimental development. However, new technical solutions tend to be fraught with old problems, and in this case, ethical and legal questions loom large over the future.
