You probably don’t notice it, but RNA is part of everything living. From the food you eat to the air you breathe, it’s at work in every cell. As far as scientists know, every living thing on Earth, from humans and plants to bacteria and even micro-organisms who live in the most extreme conditions have RNA.
Scientists are now harnessing RNA in new ways, from vaccines to therapies for cancer and genetic diseases. By studying how RNA works naturally, researchers are opening doors to treatments that were unimaginable just a few years ago.
It’s a reminder that what might seem “new” or “risky” in medicine often comes straight from the biology that’s already inside us.
