CRISPR breakthrough treats diseases like diabetes without cutting DNA

The CRISPR-Cas9 gene editing tool shows incredible promise in treating a wide range of diseases, from HIV to cancer. But the technology isn’t without controversy, as the long term effects of cutting DNA in living organisms isn’t fully known. Now, scientists from the Salk Institute have modified CRISPR to work without making any cuts, switching targeted genes on and off instead, and demonstrated its effectiveness by treating diabetes, muscular dystrophy and other diseases in mice.
