Herpes: It may actually not be so whatevs anymore. Researchers at the LSU School of Veterinary Medicine believe that the herpes virus could potentially help fight breast cancer. There's a big scientific explanation about why it's beneficial (something to do with cell replication and the immune system) that you can read about here, but essentially, it says that the herpes virus can be used to kill tumors. There's also potential for it to work as a vaccine. But don't worry, people treated with the herpes-cancer-killer wouldn't actually contract the virus. [Science Daily]
