University of Cambridge scientists have trained sheep to recognize the faces of famous people. The scientists hope facial recognition may help with their understanding of neurodegenerative diseases. The researchers showed the sheep pictures of people on two computer screens. One screen had an unknown person and the other had one of four famous people. The animals were given food for choosing the photograph of the famous person. They chose the correct photograph by breaking an infrared beam near the flat surface showing the photo. If they chose the wrong image, an electric signaling device would make a sound, and the sheep would receive no treat. The sheep eventually were able to identify the famous face eight times out of every ten tries. The group of famous personalities included actors Emma Watson and Jake Gyllenhaal, and former American president Barack Obama.
