...find would have been impossible without a new generation of infrared detector chips developed by Rockwell International for the military. "Other astronomers have similar setups," says Elston, "but we got ours going first. The rest are undoubtedly going out to find these objects...
...Borrowing technology developed by the U.S. Department of Agriculture to determine the nutritional content of meat and grain, the device beams near infrared light on the arm. As the light passes through the flesh, fat absorbs specific wavelengths; light emitted through the skin is then picked up by a detector. The computer translates the information into percent body fat. Cost of the device: around...
