What is the 'not face'? Everyone has one, say scientists.

When speaking, your face may be saying more than you know, and it's speaking a language just about anyone can understand. One particular facial expression transcends language barriers, researchers at Ohio State University found. They dubbed the universal expression the "not face" because it punctuates negative sentiments, much like the word "not." The "not face" is a combination of a furrowed brow, pressed lips, and a raised chin. The researchers found that people make this expression when expressing a negation such as "I do not agree" or "I am not going to the party."
