Scientists in South Korea created the world’s first transgenic female beagle dog carrying fluorescent genes that make it glow red under ultraviolet light.  The cloned beagle was named Ruppy (short for Ruby Puppy).

“What’s significant in this work are not the dogs expressing red colors but that we planted genes into them. The glowing dogs show it is possible to successfully insert genes with a specific trait, which could lead to implanting other, non-fluorescent genes that could help treat specific diseases, like Parkinson’s,” said Professor Byeong-Chun Lee.
