Scientists clone first rhesus monkey using new method

Scientists in China on Tuesday announced that they have cloned the first healthy rhesus monkey, a two-year-old named Retro, by tweaking the process that created Dolly the sheep. Since the historic cloning of Dolly the sheep using a technique called somatic cell nuclear transfer (SCNT) in 1996, more than 20 different animals have been created using the process, including dogs, cats, pigs and cattle.
