Researchers in South Korea have cloned a beagle, complete with an added gene that makes the dog glow bright red under UV light. Why? Well, it’s mostly a proof-of-concept; bioluminescence genes are commonly used as markers in genetic research, since they’re fairly easy to work with and can be added without interfering with other cell functions. Head researcher Byeong-Chun Lee (his name may be familiar, as he was caught falsifying results in other cloning studies) says this is the first step toward engineering dogs that are better subjects for human disease studies. Which, frankly, sounds a lot less cute than glow-in-the-dark labrodoodles.
