Experts in Uruguay have modified the genetic makeup of a group of sheep so the animals glow. Scientists from the Animal Reproduction Institute of Uruguay used a protein from the Aequarea jelly fish to attain the glow-in-the-dark results. The luminous protein was added to a flock of nine sheep which now glow under certain ultraviolet lights. 

Reports indicate that the sheep are normal and healthy aside from their unusual glowing green color. Researchers believe this technique will aid humans in tracking the development of diseases in both humans and animals.
