Hour Two: Monkeys Move Robot Arm / Human-Wildlife Encounters

As development pushes further into previously wild areas, humans are coming into contact more often with wild animals. In many parts of the country, encounters with wild animals such as deer or bears are becoming quite common. Starting in the 1980's, residents in Boulder, Colorado began to see wild cougars in town. At first, the animals were seen mainly at dusk. Gradually, however, the cougars became bolder, venturing forth in broad daylight -- and eventually became bold enough not to run from people. In this hour, we'll talk about the wild cougar, and how the case of Boulder might serve as a lesson to other areas around the country.

Plus, we'll find out about an experiment that sounds like something out of science fiction. A recent paper published in the Public Library of Science: Biology discusses the work, in which electrode-implanted monkeys were able to move a robotic arm merely by thinking about it. The work, the researchers say, could have implications for advances in medical prosthetic devices -- as well as longer-term applications to other forms of neurally-controlled electronic devices. We'll talk to one of the scientists on the project.
