Humans may be some of the most cerebral animals on the planet, but we know we’re not alone in having this sort of behavioral complexity. Crows use tools. Primates create incredible social structures. Whales congregate.

RNA gene editing could stop viruses in their tracks

The gene editing technique CRISPR promises to treat all kinds ofgenetically-linked conditions, but it’s so far limited to tweaking DNA, not the RNA that does everything from carrying protein sequence info to regulating gene expression. That may change soon, however. Scientists have discovered that a commonplace mouth bacterium (Leptotrichia shahii) can be programmed to break down whatever RNA you want. You could rip apart viruses, which are frequently based solely around RNA, or kill a cancer cell by denying it the chance to make vital proteins.
