And here I thought that this image was simply a nice photoshopped picture that somebody made for I Can Has Cheezburger! But, no, it turns out that scientists in South Korea have managed to make cloned cats that glow red when exposed to ultraviolet light! By using a virus to insert a genetic marker for generating fluorescent proteins, the researchers have made what will probably become the next big novelty pet craze. Worried about your cat attacking your ankles without warning? Flick on the black light, and see where she’s hiding! (Warning: You might find more than you bargained for…)

In all seriousness, this is an amazing accomplishment. Being able to insert functional genes into an animal means that better research can be done on a variety of genetic diseases, which means that better treatment options may soon become available for such diseases.
