Meet Retro — the first rhesus monkey cloned using a new scientific 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. Primates have proved particularly difficult to clone, and the scientists overcame years of failure by replacing the cloned cells that would become the placenta with those from
