WASHINGTON — Scientists have created the first genetically modified monkeys that can pass their new genetic attributes to their offspring, a development designed to give researchers new tools for studying human disease, but one that raises a host of thorny ethical questions.
In this case, the Japanese researchers added genes that caused the animals to glow green under a fluorescent light and beget offspring with the same spooky ability. They hope to use the technique to produce animals with Parkinson's, Huntington's and other diseases.
