Green eggs and ham?

Scientists in Taiwan say they have bred three pigs that glow in the dark. They claim that while other researchers have bred partly fluorescent pigs, theirs are the only pigs in the world which are green through and through. The pigs are transgenic, created by adding genetic material from jellyfish into a normal pig embryo. They are the only ones that are green from the inside out. Even their heart and internal organs are green, they say. In daylight the researchers say the pigs' eyes, teeth and trotters look green. Their skin has a greenish tinge. In the dark, shine a blue light on them and they glow torch-light bright. The scientists will use the transgenic pigs to study human disease. Because the pig's genetic material is green, it is easy to spot.
