...measure the near-imperceptible changes in a star’s light that are induced by orbiting planets. Planet gravity minutely affects the color of light emitted by stars they orbit by altering the star’s own movements. Such light changes—called “doppler shifts”—produce redder light when gravity nudges the star towards an observer and bluer light when gravity moves it away. But these shifts are often too small to accurately measure. “You could find Jupiters but you couldn’t find Earths...
...RADAR Doppler weather radars give details on a storm's wind change as it crawls closer to the coast, scanning once every six minutes (plane observations come in only once every few hours...
...simple premise: some clouds are better for seeding than others. Up to now, the right weather-measuring tools have never been in the right program at the right time. Starting in November, they will be. A project staff of about 30 will use a recently installed CP2 Doppler radar to analyze what's happening in Queensland's clouds before, during and after materials like silver iodide and salt are sprayed into them from planes. Working in tandem with other ground radars and forecasting equipment, the technology will be able to do a three-dimensional reading of the atmosphere - similar...

Starting in November, they will be. A project staff of about 30 will use a recently installed CP2 Doppler radar to analyze what's happening in the regions' clouds before, during and after silver iodide "seeds" are sprayed into them from planes. Working in tandem with other ground radars and forecasting equipment, the technology will be able to take a 3-D read of the atmosphere similar to a body scan...
...Consider first the vascular test: All orthopedic surgeons have a great respect for phlebitis. Thrombosis (clotting) in the big veins of the legs is among the top killers of orthopedic patients. And calf pain is one of the signs. I never faulted anyone for getting a Doppler, the test for the blood clots. I have seen patients with barely any calf pain at all fall over dead from the things - you can't be too careful. A recent scare about Vice President Dick Cheney's calf clots showed how seriously doctors take them. Tim was a little tender (albeit...
