Researchers have made significant strides in the development of quantum dot infrared photodetectors -- technology that may provide new imaging techniques with applications in medical and biological imaging, environmental and chemical monitoring, night vision and infrared imaging from space. Conventional technology for imaging applications typically requires that the detector be cooled to very low temperatures. By using nanotechnology to form quantum dots, the researchers are closer to developing high-performance imaging techniques that can operate at higher temperatures.

Hurricane forecasters will test a new technique this summer that provides a detailed 3-D view of an approaching storm every six minutes and shows whether the storm is gathering strength as it nears land. The technique, which relies on existing coastal radars, will help meteorologists quickly alert coastal communities.
