Scientists Create Glow-in-the-Dark Sheep
May 3, 2013

 Forget about the elusive black sheep; now we have glow-in-the-dark flocks. Scientists in Uruguay have successfully modified the genetic makeup of a group of sheep so that the animals glow.   
 
  Experts from the Animal Reproduction Institute of Uruguay used a protein from the Aequarea jelly fish to achieve the glow-in-the-dark results. The fluorescent protein was added to a flock of nine sheep, which now glow green under certain ultraviolet lights. 
 
Aside from this unusual hue, all the sheep are normal and healthy. All these glowing animals aren't just for fun and games - researchers believe this technique can help humans track the development of diseases in both humans and animals.
