Gene-editing tool CRISPR can now manipulate more types of genetic material

The powerful gene-editing tool CRISPR has been making headlines for its ability to edit DNA, which could one day transform how we fight cancer and other life-threatening diseases. Now, scientists have created a new version of CRISPR that can target and edit a different genetic building block: RNA.
The new tool, described in a study published today in Science, offers several advantages: its edits, for instance, aren’t permanent, which makes gene editing much safer. Researchers showed that t
