It’s not easy to treat viral infections. Just ask anyone with a bad cold or a case of the flu.
But scientists in Massachusetts think they may have a new way to stop viruses from making people sick by using what amounts to a pair of molecular scissors, known as CRISPR.
It’s a gene editing tool based on a molecule that occurs naturally in microorganisms.
CRISPR comes in many “flavors” that perform a variety of functions inside cells. The Cas9 flavor has been widely used as a tool for editing DNA inside cells. It’s already shown promise for medical therapies such as treating sickle cell disease.
