New Organic Material may Speed Internet Access

The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard. In the morning, the bricks will be covered with snow and barely discernible. The snowflakes will have filled every vacant space between and around the bricks.What you will see, says Ivan Biaggio, resembles a phenomenon that, when it occurs at the smallest of scales on an integrated optical circuit, could hasten the day when the Internet works at superfast speeds.
