Just in time to be late for Christmas!
Ostensibly for stem cell research, scientists in Taiwan claim to have developed a green, phosphorescent pig. They aren't the first and they won't be the last. But, dammit, they've done it!
The pigs are transgenic, created by adding genetic material from jellyfish into a normal pig embryo. In daylight the pigs' eyes, teeth and trotters are a sickly yellow-green. Their skin has a greenish tinge. In the dark, shine a blacklight light on them and they glow torch-light bright. Great for raves!
Why have they done it?
The transgenic pigs will be used to study human disease. The pig's genetic material is easy to spot. It's freakin' green.
