SCIENTISTS have created glow-in-the-dark MONKEYS to help
understand how genes are passed down to offspring. Researchers
in Japan first created a genetic virus containing a green
fluorescent gene. They exposed female marmoset primates to it so
it merged with their DNA and was passed down to their offspring
a world first. The baby monkeys feet then glowed bright green
under ultraviolet light. Scientists will study them to find why
certain genes cause diseases in some babies but not others.
