IBM and Caltech experiment with DNA-size computer chips

Gadget makers have for decades relied on ever-shrinking microchips to make more portable, yet more powerful, devices. But as the components used to make these chips become smaller, with widths measured in dozens rather than hundreds of nanometers, they become increasingly more difficult to assemble.  Since microchips are the engines performing the logic functions that make computers, cell phones and countless other electronic gadgets run, technology makers like IBM have been looking to pack more transistors closer together in smaller spaces.  Now comes a potential solution...
