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 teamĂ‚Â’s stem cell research-these cells could be customised to the needs of seriously-ill patients from donor cells. The teamĂ‚Â’s announcement raised bioethical questions and later suffered a debacle when allegations were raised that WooĂ‚Â’s 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: Woo-Suk Hwang with Snuppy in happier days.
