Last month 29 miners were killed in West Virginia in the worst mining disaster to strike America in four decades. In an effort to prevent future mining tragedies, Col. Jim Squire, Lt. Col. Jay Sullivan, and Maj. Elizabeth Baker (Virginia Military Institute) have developed a device that uses seismic waves to communicate with miners trapped underground following a mine collapse. Also: Imagine a world where robots, instead of humans, get to do all the hard work. Such an environment would not only offer unparalleled convenience, but it could also save human lives. Dennis Hong (Virginia Tech) heads a research lab which focuses on robot design and creation.
