There's an article in Science from last Friday about finding families of bacterial enzymes that take an RNA template and edit DNA where the template matches. The families appear to be related to the enzymes used in CRISPR, and there are lots of them. So where CRISPR was the molecular scissors which would let us tailor DNA as we liked, we've now found the tailor's workshop filled with hundreds, thousands, or perhaps millions of different molecular scissors. The workshop was hiding in the bacterial junk DNA.
