Nature can improve our computers

Robots on Mars that can fix themselves and computers built from DNA: not science fiction but the work of scientists at the forefront of computing.

Dennis Shasha, 55, is a professor of computer science at New York University's Courant Institute of Mathematical Sciences and the author, with Cathy Lazere, of Natural Computing: DNA, Quantum Bits and the Future of Smart Machines (Norton), a survey of research in fields as disparate as engineering and medicine. This New Yorker sees an emerging common theme: that the future of computing lies in a synthesis with nature.
