Dolphins do it. Big brown bats do it. And sometime soon, the Office of Naval Research hopes its researchers will be able to do it too. Echolocation, that is, and turning the processing of such signals ...

Bioengineers have developed a new class of bionic 3D camera systems that can mimic flies' multiview vision and bats' natural sonar sensing, resulting in multidimensional imaging with extraordinary ...

A new Tel Aviv University study has found that fruit bats use their biological sonar during the day, even though their vision is excellent and would ostensibly eliminate the need for the bats to emit ...
