...boated the bomb was CURV (for Cable-Controlled Underwater Research Vehicle), weirdest of all of Guest's gadgets. On a 15-ft. pipe base not unlike the landing gear of a small helicopter, CURV mounts four long red ballast tubes for depth control, three electric propulsion motors, lights, sonar, film and TV cameras. Controlled from the surface, it can clamp a detachable claw onto objects up to 3 ft. wide, then back away leaving the claw and a buoyed line attached. Though it is normally used to retrieve spent torpedoes, Guest acted on a hunch and ordered CURV flown...
Already, the 15 vessels of Task Force 65, the largest and most sophisticated search group in naval history, had gathered in the area. While 120 Navy divers made a shoulder-to-shoulder search along five miles of coastal water, ships equipped with ultra-sensitive sonar crisscrossed the 120-sq.-mi. search zone. But Rear Admiral William S. Guest, 50, commander of the task force, ordered three weird-looking submersibles, especially designed for deep-sea research, to pay special attention to the spot around the buoy...
Soon West Coast fishermen are going to be raising much more hake. Sonar soundings conducted by the Interior Department's Bureau of Commercial Fisheries have detected vast schools of hake in the usually unfished mid-waters between the ocean surface and the bottom...

...newer detection methods is echoencephalography, working on the same principle as sonar. When sound waves are bounced in and out of the head and converted into a light pattern, the neurologist can see whether the brain has been shoved to one side by blood or a clot. Injections of radiopaque dye also help X rays to show whether arteries have been displaced or damaged enough to deprive part of the brain of its blood supply. Even using these techniques, doctors do not always discover everything...
