This is so Mr. Ed, but it's true!

Horses can read, remember and react to human expressions.

Popular Mechanics says the surprising new findings come from the University of Sussex in the U.K. and the University of Portsmouth in Pittsburgh. They showed domestic horses photos of an angry or happy human face.

Several hours later, they introduced the horses to the actual person photographed.

The horses reacted differently depending on the photo they'd seen. Animals process threatening stimuli in their right brain-hemisphere, using their left eye, so the direction of the horse's gaze revealed their read of the photograph.

They did not have any reaction to strangers whose photos they had never seen before. That means horses have a memory for emotion.
