An avid science fiction fan as a child, Wakayama turned his attention to cloning a little more than a year ago. Surprisingly, his method of injecting embryos -- now dubbed the Honolulu technique -- has emerged as the world's first truly reliable blueprint for building a clone. "It's very reproduceable," says TIME science reporter Alice Park. "With this method, you can start with a mouse and at the end of the day have a clone in your hand."
So man can build a better mouse. And Dolly the sheep, who until yesterday was the only mammal clone proved to come from an adult cell, is no longer alone. Now researchers plan to try the Honolulu technique on cows, sheep and pigs. This could lead to improved AIDS, cancer and aging research -- not to mention the inevitable fears over human cloning. One thing's for certain: The Age of Genetic Engineering has well and truly begun.
