What would you get if you crossed a dolphin and a cellular phone? A phone with a lot more channels, says University of Rochester professor Edward Titlebaum.
Titlebaum is searching for ways to increase the number of channels available to users of sonar, radar, cellular telephones and satellites. He takes his research cues from dolphins and other animals such as bats whose sonar systems are much more sophisticated than manmade systems."I sit back and learn from the sonar systems nature has provided," he explains.
