They are the long-forgotten acoustic reflectors, dubbed by locals as the “listening ears.” These lonely structures were built to protect harbors and coastal towns from airborne attacks. Serving as an early warning system, microphones placed at the focal point of the reflector enabled it to detect sounds from flying aircraft over the English Channel, at a range of 30 kilometers. Thanks to acoustic pioneer William Tucker, who helped the radar teams pinpoint enemy aircraft and their movements, the system helped a seemingly inferior, and nearly obsolete, radar system effectively detect German bombers and fighters, and to, ultimately, help win the Battle of Britain.
"My camera is really the least important part of the shots," Horsford writes in an e-mail. The trick seems to be in the timing of the flash. He sets a timer on his camera to take a long exposure of 1 to 2 seconds, and if the flash fires within that time, he gets an image. He uses a special gizmo with a microphone that triggers the flashes when it picks up a certain level of sound (i.e., the pop of a balloon).
A radioactive rabbit was trapped on the Hanford nuclear reservation, but there is no sign any people were exposed to the animal.
Washington state Health Department workers with the Office of Radiation Protection have been searching for contaminated rabbit droppings.[...]
The rabbit trapped at the 300 Area caught the Health Department's attention because it was close enough to the site's boundaries to potentially come in contact with people - if it had been caught by a dog or if its droppings were deposited in an area open to the public.
