I couldn't discover the reason for this experiment. Something that makes sense?
More on this. They have actually made several different Glow In The Dark Critters including blacklight glowing piglets
Why, you ask?
The pigs' embryos were injected with a molecule from bioluminescent jellyfish that carries instructions to make green fluorescent protein, or GFP. This technique allows researchers to attach harmless glow-in-the-dark tags to specific proteins in animals. The scientists who discovered and developed GFP earned a Nobel Prize in 2008, and researchers have previously created glowing bunnies, frogs and even glow-in-the-dark cats in the name of science.
Kinda puts a new "light" on putting out the cat at night.
