Microbes’ mystery DNA helps defeat viruses—and has genome-editing potential

I’ve got to get on watching genetics videos so I can understand all the terms in this article, but what’s described here is really cool.

Plus, biblical metaphors when talking about science is pretty cool too. :slightly_smiling_face:

Researchers are excited about retrons, but caution they have a lot to learn about how to turn these bacterial swords into plowshares. “It could be that retrons will be as revolutionary as CRISPR has been,” Simon says. “But until we understand more about the natural biology and synthetic behavior of retrons, it is difficult to say.”
