Companies like GE run multilingual trading sites, such as gepolymerland.com courting customers in 11 languages, including Portuguese and Chinese. Life-sciences and finance companies are also bolstering demand. When California-based ADAC Laboratories needed a quick Italian version of technical documents for a positron emission tomography scanner, it turned to Berlitz GlobalNET, which finished the job in 10 days. When Morgan Stanley and Prudential need translations of research reports and marketing materials into Japanese, German and other languages, they often turn to Lionbridge...
...SCAN A lot of patients are taking it upon themselves to order their own positron emission tomography scan. This extremely powerful test screens your body's function rather than its structure; by visualizing cellular activity, it shows abnormal processes, such as those associated with cancers and metabolic dysfunction. The PET can spot tumors and other problems that may not be detectable with traditional MRI or CT scans. It also gives information about heart disease and many neurological disorders like Alzheimer's. Cost...
...time, eight years ago, PET (positron emission tomography) machines, which can reveal subtle metabolic processes such as tumor growth, and CT (computerized tomography) scanners, which show precise anatomical details, were already in widespread medical use. But doctors, especially cancer surgeons, were often frustrated in their attempts to match the two different scans to determine, for example, the precise location of a tumor in relation to an organ or to the spinal column. There seemed to be no better way than simply "eyeballing" the two separate images...
...laws of physics permit time travel, even in principle? They may in the subatomic world. A positron (the antiparticle associated with the electron) can be considered to be an electron going backward in time. Thus, if we create an electron-positron pair and the positron later annihilates in a collision with another, different electron, we could view this as a single electron executing a zigzag, N-shaped path through time: forward in time as an electron, then backward in time as a positron, then forward in time again as an electron...
