CRISPR/C2c2

You've probably heard of CRISPR - the gene editing tool that essentially lets scientists cut and paste DNA, removing things like HIV and muscular dystrophy from our cells - and now scientists have discovered a way to edit RNA with just as much precision. RNA is DNA's close biological cousin, responsible for translating messages from the nucleus to the rest of the cell, and being able to change it could open up all-new disease-fighting possibilities.
