Yahoo says they didn't tweak the brain. Rather, they eliminated certain nasal cells that alert mice that inherently scary cats are nearby. Without those cells, the brain doesn't get the message to be afraid. So the mice pal around with the cats, until the cats get bored.
The article seems to say that with more research, we could cure fear. That would be great for people who are pathologically afraid.
