          | Description: 
             Researchers made this pair 
            of 10-micron-wide copper lines by printing an 80-micron ribbon of 
            copper solution onto glass with an inkjet printer, allowing it to 
            evaporate into a pair of much thinner lines, and then heating them 
            to produce pure copper. |
