Memory-boosting via Multivitamins?

Multivitamins help prevent memory loss (start time: 8:02) In this week’s  show, How On Earth host/producer Susan Moran interviews Dr. Adam Brickman, a neuropsychologist at Columbia University’s Vagelos College of Physicians and Surgeons, about a large new study that shows how taking multivitamins can prevent memory loss in older adults. Memory decline is an inevitable, if cruel, component of aging. And there’s been much debate about what interventions can arrest the pace of memory loss. The new study, which Dr. Brickman co-authored, replicated results of a previous study that he led; both found that people age 60 and older who take multivitamin supplements daily can stave off normal age-related memory loss. (The study does not apply to people with Alzheimer’s disease or other forms of dementia.)

Bears: Beloved & Imperiled

Of Bears & Humans (start time: 1:34) If you live on the Front Range or in the mountains, you’ve probably seen a black bear while hiking or in your neighborhood.  Black bears are thriving, but most of the other eight remaining bear species are struggling to survive. How On Earth host Susan Moran interviews journalist Gloria Dickie about her just-published debut book Eight Bears: Mythic Past and Imperiled Future  (W.W. Norton). It explores conservation efforts to preserve the remaining species. Spoiler alert: the eight bears who inhabit Dickie’s book (and parts of the planet) are the black, brown, panda, moon, sun, sloth, and spectacled bears.  Dickie’s work has appeared in many publications, including  The New York Times, High Country News and National Geographic. She is currently based in London, as a global climate and environment correspondent for Reuters.

Your Brain On (and off) Chronic Pain: Part I

chronic pain on the brain

Chronic pain science and treatments (start time: 4:27) In this week’s show host Susan Moran interviews two experts on the emerging neuroscience of and mind-body treatments for chronic pain, which is a leading cause of disability in the U.S. As many as one in five Americans suffer from chronic pain. The problem has cost the country more than $600 billion in treatments and lost work-time. Our guests today are at the forefront of research and clinical treatment of chronic pain. Dr. Yoni Ashar is an assistant professor at the University of Colorado Anschutz Medical Campus in the Department of Internal Medicine. Several years ago he led the Boulder Back Pain Study on a mind-body program called Pain Reprocessing Therapy.  Brad Fanestil, MD, is an internist and the director of the Center for Mind Body Medicine at Boulder Community Health. Stay tuned for details on a Part II discussion on mind-body medical treatments for chronic pain, anxiety and other ailments.
Relevant resources:
* New randomized back-pain study (led by Dr. Ashar) seeks subjects.
* The Way Out, by Alan Gordon
* Lecture by Dr. Fanestil on treating chronic pain with mind-body medicine
* Curable app for managing chronic pain

Water Reuse for the Arid West

Water Recycling for Climate Resilience (start time: 7:54) When you poured tap water into your coffee maker this morning, or flushed the toilet, you may not have been thinking about where that water came from, or where it flowed to next. Pegged to World Water Week, on this week’s How On Earth host Susan Moran interviews Austa Parker, PhD, an environmental engineer who is a consultant for the firm Brown and Caldwell on national water-reuse issues. She formerly worked for Denver Water and as an adjunct professor at CU Boulder. Our discussion focuses on direct potable reuse (DPR), the process of transforming treated wastewater, including human effluence, into drinking water. Climate change, intensifying droughts and population growth in the already parched U.S. West are pressuring states and cities to pursue DPR as a means of becoming more climate-resilient.

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

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?
