Turns out, our bodies are hiding a wild secret: scientists just discovered a totally new kind of microscopic life called Obelisks living in our mouths and guts. These weird RNA strands don’t fit into any known category—virus, bacteria, or anything else. They infect our microbes, not us, and might be a whole new branch on biology’s family tree. Who knows what else is lurking in our microbiome? The science textbooks are about to get a rewrite! #Science #science #biology
