Nowadays, touch screens appear on everything from cell phones to smart refrigerators. Our modern e-book readers and Black. Berries were also foretold by the small computerized tablets that the Star Trek crew used for reading and storing data. And just as the Star Trek crew could always find its location when on missions to foreign planets by using scanners, we can now do this on Earth by using a GPS (Global Positioning System) device. Some of the medical technologies on Star Trek have also become reality. In the show, brain surgery was performed by attaching a gadget to someone's head, which healed internal injuries without cutting into the brain. There is now a similar procedure called gamma ray surgery, where a number of beams of gamma radiation are precisely focused at a single target-for example, a brain tumor. This dissolves and eliminates the diseased area. Since the procedure is non-invasive, there is little pain and much less chance for infection. Star Trek doctors also diagnosed patients using the versatile handheld tricorder scanners. (In fact, the Star Trek tricorder seemed to do everything, from checking a planet's atmosphere to diagnosing a broken engine!) Modern patients are scanned in essentially the same way, by magnetic resonance imaging (MRI) and CTscans, although the equipment is much larger than a handheld device. Even the crusty Dr. McCoy would be impressed. Another Star Trek technology that appears to be within reach is the universal communicator. A number of translators already are available on the Internet, and they do a fair (although far from perfect) job of translating written texts. But translating speech is much more difficult. People speak with a wide variety of dialects and accents, which current voice recognition systems simply cannot cope with. For the best results, the software must be trained to each speaker's individual voice. However, improvements gradually are being made, and it may be years rather than decades before sufficiently powerful voice recognition software makes simultaneous oral translations possible. With advances such as these, it is fair, exciting, and perhaps a bit frightening to ask, how far behind can Mr. Spock's telepathic "mind-meld" communication be?
