Glowing Animals: Pictures of Beasts Shining for Science
How does it glow? Red fluorescent protein, introduced via a virus into cloned DNA, which was implanted in cat eggs, then implanted in mother (2007)
What can we learn? Scientists at Gyoengsang National University in South Korea both cloned a Turkish Angora house cat and made it fluorescent—as shown in the glowing cat (left) photographed in a dark room under ultraviolet light. (The nonfluorescent cat, at right, appears green in these conditions.)
The scientists weren’t the first to clone a cat—they weren’t even the first to clone a fluorescent cat. But they were the first to clone a cat that fluoresces red. It’s hoped that the red glow, which appears in every organ of the cats, will improve the study of genetic diseases.
