摘要

"It's getting a little challenging," says A Angela Belcher. "I feel I am having to make choices now, which I never really wanted to." But there are only so many hours in the day and she already combines multiple academic disciplines into a repertoire of research that spans an ambition to drive an electric car powered by a virus battery to building better touch-screens for digital devices and lately to giving surgeons new tools to detect and potentially treat minute traces of cancer. There is more, but as eclectic as her work seems, it is united by a single intriguing idea. Evolution is a great problem solver and over millions of years has produced creatures of incredible breadth and complexity that can survive in the changing world around them. So why not copy the way nature innovates, speed it up and use it to help solve some of the problems researchers are presently working on. And that, in essence, is what Dr Belcher and her colleagues at the Massachusetts Institute of Technology (mit) do. They rapidly evolve genetically engineered organisms to manufacture new materials and devices.
