Get this: about 8% of your DNA is from ancient viruses, and scientists just snapped the first-ever pics of a viral protein (HERV-K) that pops up in cancer, lupus, and ALS. This protein comes from a virus that infected our ancestors millions of years ago—and now it’s reactivated in some diseases. The wild part? Researchers made antibodies that light up only diseased cells, opening the door for new cancer and autoimmune treatments. Our old viral baggage is causing drama! #Health #BodyHealth #ScienceNews
