The CRISPR-Cas9 system has revolutionized genetic engineering. This groundbreaking discovery by scientists Jennifer Doudna and Emmanuelle Charpentier has brought medical research light-years closer to finding a cure for many diseases, including sickle cell anemia, HIV, cancer, Huntington’s disease and more.


To make efficient and reliable ways to make precise, targeted changes to the genome of living cells is long sought goal for medical research. And recently, a new tool based on a bacterial CRISPR-associated protein-9 nuclease (Cas9) from Streptococcus pyogenes has made significant progress.
