The Little Book of Aliens

The Little Book of AliensIn this Halloween episode, we talk with Dr. Adam Frank, an astrophysicst/astrobiologist at the University of Rochester, about his recent book: The Little Book of Aliens. We hear some of the stories and learn about the science of life “out there” – astrobiology – and the past, present, and future search for extraterrestrial intelligence.

Recovery: The Lost Art of Convalescence (excerpts) / Fund Drive

As part of the KGNU Fund Drive, this episode of How on Earth features excerpts of Beth Bennett’s interview of Dr. Gavin Francis about his book Recovery: The Lost Art of Convalescence. We explore the difference between sickness and health, and the gap between them: Recovery. Based on decades of treating disease and injury, Dr Francis proposes a more active role of the individual in their recovery.  We also talk about the importance of self-care and compassion, the role of the environment we create for ourselves, and the importance of caregivers.

AI or not AI, that is the question — ChatGPT, DALL-E, and Generative Artificial Intelligence in the Human World

A DALL-E generated image of this interview
A DALL-E generated image of this interview.

We talk with Dr. Casey Fiesler, Associate Professor of Information Science at the University of Colorado, Boulder about “generative AI,” particularly regarding ChatGPT and DALL-E, which are topics of recent news stories expressing excitement and concern.

We asked ChatGPT to write a description of what such an interview might be:

Dr. Casey Fiesler joins Joel Parker on the KGNU radio science show How on Earth to discuss generative AI and its recent breakthroughs, such as ChatGPT and DALL-E. Fiesler explains that these AI models use deep learning algorithms to generate new content, such as text or images, based on patterns found in existing data. She acknowledges the impressive capabilities of these models, such as DALL-E’s ability to create highly realistic images from textual prompts. However, Fiesler also raises concerns about the potential negative impacts of generative AI, including the perpetuation of biases found in training data or the creation of harmful fake content. Fiesler emphasizes the importance of responsible development and use of these technologies, as well as ongoing research into addressing these issues.

After you listen to the show, you can determine how accurate is that description.  And can you identify the three interview questions we asked that were generated by ChatGPT?

Grass-Fed Beef for a Post-Pandemic World

How on Earth’s Beth Bennett talks with authors Ridge Shinn and Lynne Pledger about how regenerative grazing can replace corn-based feedlots, which are responsible for significant climate emissions, nitrogen pollution, and animal suffering. Their book, Grass-Fed Beef for a Post-Pandemic World, outlines a hopeful path out of our broken food system via regional networks of regeneratively produced meat. They talk about how this ancient method of animal husbandry can restore degraded farmland, increase biodiversity, combat climate change by reducing emissions and sequestering carbon and produce nutrient-dense, healthy meat for consumers.  More information at Big Picture Beef.

Also, Shelley Schlender talks with Sarah Johnson, a professor of food, science and human nutrition at Colorado State University, about a recent study indicating that in mice prone to artery disease, those that ate belgian endive reduced the instability of artery plaques. That may be important, because in people, unstable plaques can trigger heart attacks.
