South Korean scientists say they have engineered four dogs to glow red, using cloning techniques.
The four, all named Ruppy--a combination of "ruby" and {puppy"--look like typical canines by daylight. But they glow red under ultraviolet light, and their nails and abdomens, which have thin skin, look red even to the naked eye.
Professor Lee Byeong-chun of Seoul National University, the leader of the research team, called them the world's first transgenic dogs carrying fluorescent genes, an achievement that goes beyond just their glowing.
"What's significant in this work is no the dogs possessing red colors but that we planted genes into them," the professor said.
