A team at Seoul National University in South Korea has produced the first transgenic cloned dog, a cloned beagle named Ruppy (short for Ruby Puppy.) She and four other beagles all produce a fluorescent protein that glows red under ultraviolet light. The results provide a proof-of-principle experiment that dogs can be genetically engineered (they had already been cloned first in 2005, by this team along with disgraced scientist Woo Suk Hwang), supposedly opening up possibilities to use genetically-engineered dogs as disease models for study. Scientists note that this shows that cloning and genetic engineering can be applied to a wide range of mammals. The report is published in the journal Genesis.
