Ruppy, the world's first glow-in-the-dark puppy, came to life recently, when a team of South Korean scientists extracted fibroblast cells found in sea anemons, which were then virally injected into the puppy's nucleus. Apparently, Ruppy is genetically designed to produce a florescent protein that glows red under UV light.

Thanks to science and stem cell research, we can anticipate all sorts of mammals loaded with radiant genes in the near future, like self-illuminating cows and pigs (seriously, they're working on it). What to do with a little puppy that glows in black light? Hit the raves, duh.
