GEORGE Cloney is some pig. He's the first to be cloned by a technique that is apparently twice as efficient as previous methods and only one-tenth as costly. The first step in cloning a mammal is to strip an egg cell of its own nucleus. This is usually done by the process known a enucleation, in which a needle is used to suck the nucleus out of the egg. The new technique, called "handmade cloning", achieves the equivalent by simply chopping the egg in half.
