In fact, Minsky was disappointed with the lack of progress in the field and had reservations about its future. Unfortunately, Minsky is no longer with us and can’t answer our questions about machine learning and new robots, but his answers from this interview in many ways stil...

Thurston, Director of the Program in Exposure Assessment and Human Health Effects at the Departmen...

For more than three decades, behavioral biologist Denise Herzing has tracked and observed a pod of wild spotted dolphins that live in the warm clear waters of the Bahamas. She’s learned an awful lot about their behaviors and their communication–or is it a language? Denise has as good a chance as anyone to find out what the dolphins might be saying to each other. But the question is: if we could commu...

Methane is a Dr. Jekyll and Mr. Hyde kind of gas: on one hand, it is the cleanest-burning fossil fuel. On the other, if it leaks, methane itself is a much more potent greenhouse gas than carbon dioxide. In this special Hash It Out episode, Brian and Fedor go from 18th century Italian methane guns to present day Google Street View cars that sniff out methane leaks. Listen to learn about the history of methane, its current uses, and ...
