Montevideo, Uruguay - Scientists in Uruguay have announced the world's first genetically-modified phosphorescent sheep.
Nine sheep were born in October of 2012 at Uruguay's Institute of Animal Reproduction, an experiment conducted in conjunction with the Institut Pasteur.
The scientists used a gene from a jellyfish, allowing them to produce a green fluorescent protein.
The scientists say the sheep developed normally. They claim there are no differences to their non-modified peers.
