I was just reading an article on IO9 that describes new tech that brings us a few steps closer to that marvelous Star Trek device known as the "Tri-corder". The small, battery powered device small device uses a low-power ultra-violet laser beams to identify the building blocks of life. The device could sweep the lasers over rocks or soil, identifying identify organic substances. Scientists foresee this as a hand-held unit, but presently uses are aimed at future robotic missions.
