To clone or not to clone
2005 can go down in history as the year of cloning as it saw successes and debacles in equal measure. In May, South Korean scientists led by the maverick Woo-Suk Hwang announced an advancement in his teamÃÂs stem cell research-these cells could be customised to the needs of seriously-ill patients from donor cells. The teamÃÂs announcement raised bioethical questions and later suffered a debacle when allegations were raised that WooÃÂs female colleagues had contributed their eggs. Woo resigned soon. But earlier Woo did achieve a milestone by producing the first cloned dog, Snuppy, which the Time magazine named Invention of the Year. In pic:
