Communicating with dolphins

Dolphins are intelligent and communicative creatures within their own species and with the other animals native to their waters. Still, a hundred million years of evolutionary history and pressures imposed by radically different environments separate dolphins and humans. Can that enormous chasm be crossed? Can we have a conversation with an alien, a different and intelligent species? Twenty-seven years ago, Dr. Denise Herzing first slipped into the warm and clear Bahaman waters in a quest to answer those questions. And every spring since then, she has gathered the crew, the equipment, the money, the courage and the patience to return to work cooperatively with them, unfettered in the wild. Dr. Herzing believes that first we have to understand dolphin society and give them the freedom to choose to communicate with us. This week on How On Earth, Jim Pullen talks with Dr. Herzing about how she communicates with Atlantic Spotted dolphins (start at 6:48).

Boulder Robotics // Compassion

Boulder is for Robotics (start time 4:00). “It starts really with the fact that a lot of robotics materials, sensors and manufacturing are here in Colorado.” Boulder as a hub for robotics? You bet. KGNU’s Tom McKinnon reports from the first Boulder is for Robotics meetup, which drew over 100 participants. Learn about some local projects, from robots for agriculture to robots for kids.

The Neurology of Compassion (start time 12:50). “Someone on the street asks you for money. Do you give or not? What drives that decision?” Researchers Jessica Andrews-Hanna and Yoni Ashar from University of Colorado’s Cognitive and Affective Neuroscience Lab talk to us about the causes and effects of compassion. The first of their studies on compassion looks at charitable giving. What determines whether a person will decide to donate part of their earnings? They also talk to us about their current study, which involves using brain scans to evaluate the effect of compassion meditation.

Wild Turkeys // Light Pollution

In celebration of Thanksgiving, Beth Bartel interviews Stan Baker of the National Wild Turkey Federation about wild turkeys in Colorado. You may be surprised at the story of the wild turkey in North America and just how different the wild turkey is from the domestic turkeys we’re used to. There’s a reason Benjamin Franklin wanted the turkey, not the bald eagle, to be our national bird.

Can light pollution at night lead to air pollution during the day? Jim Pullen talks with researcher Harald Stark of the Cooperative Institute for Research in the Environmental Sciences (CIRES) to find out. Stark’s work has taken him over Los Angeles to measure the chemistry of the night sky. What he is learning increases our understanding of ground-level ozone, which is a major pollutant of our urban air.

This week on How On Earth, University of Colorado earth scientist Roger Bilham joins us in the studio to talk about his latest study, which shows a correlation between the prevalence of corruption in a country and the likelihood of civilian deaths during an earthquake. And Shelley Schlender talks to HOE contributor and astrophysicist Joel Parker about how the science of astronomy can have an impact on the pseudoscientific world of astrology.
