Virtual DNA replicates
A simple type of virtual DNA has replicated itself, opening a window on biology and pointing the way for nanotechnology. The next step is causing the code to carry out tasks beyond propagation. The sky's the limit -- imagine automobiles grown in vats of chemicals.

Quantum computing catches the bus
Getting data from point A to point B within a large quantum computer is a tricky proposition. A scheme that uses a component found in virtually every computer that's ever existed could cut the potentially high overhead of quantum computers considerably. It all comes down to building a good bus.
