Magnetic Braking in Old Stars (starts at 3:13)  Dr. Travis Metcalfe from the White Dwarf Research Corporation talks about studies of one particular star, 51 Peg, that has gone through magnetic braking. He discussed how studying magnetic fields around similarly middle-aged and older stars not oly can help us in our search for life on other planets, but also provide a clue of what might have impacted the evolution of life here on Earth.

Citizen Science with Zooniverse (starts at 13:21) Dr. Laura Trouille from the Adler Planetarium is the Principal Investigator of the Zooniverse project.  She explains how “citizen science” works, which crowd-sources science research in a wide range of projects not only in astronomy, but topics ranging from biology and physics to arts and literature.

Ibogaine for Traumatic Brain Injury – The Science journal Nature has published a small case study about Special Forces veterans who suffer from traumatic brain injury . . . they report good results from one single dose of the illegal psychedelic Ibogaine . . . with careful supervision.

Andrew Linares – Boulder Therapist

Ibogaine – Huberman Lab discussion with Nolan Williams (Starts 3:45)  Stanford scientists discuss therapeutic use of Ibogaine.

Ibogaine – Boulder Therapist Andrew Linares  (Starts 7:00) shares his experiences working with special forces veterans who are taking Ibogaine at a clinic in Mexico, where it is a legal drug.

Lynx – from Endangered Species.org

Lynx Habitat battle this Wednesday (starts 1:00) Denver’s US 10th District Court of Appeals will hear a case about U.S. Forest Service plans for environmental rollbacks in southern Colorado’s Rio Grande National Forest.  They plan to log beetle-killed trees -which may disrupt old growth forest that the endangered lynx needs.  Environmentalists are pushing for more study about the impact of these plans.

A New Year and the Same Old Environmental Issues

On this week’s show, we focus on the ongoing challenge of climate change. In addition to headlines about this issue, we replay an interview with author John Vaillant, who has written extensively about the natural world over his long career. In his new book, Fire Weather:A True Story from a Hotter World, he explores the phenomena of fire, the wildland urban interface, and climate change in the context of a precedent-shattering combustion in a modern city.This colossal wildfire in Alberta in 2016 almost consumed a city of nearly 100,000. In the process the fire blew up expectations and responses to wild fires. Vaillant gives an in depth exploration of the rapidly changing relationship between fire and humankind along with personal stories of loss and bravery on the front lines of this horrifying event.

STEM Ed: Improving access for the blind, etc.

Photo credit: National Science Foundation

STEM ed accessibility (start time: 2:03): It’s challenging enough learning science, technology, engineering and math when you can clearly see the physical models or images of neurons on a screen.  So, imagine the hurdles faced by students who are blind or otherwise visually impaired? In this week’s show, host Susan Moran interviews two chemists who are working on making STEM education  more accessible to people with visual and other impairments, and on making learning more interactive for everyone.  Dr. Hoby Wedler is an organic chemist, a sensory expert, and a product development consultant based in Petaluma, Calif. Blind since birth, he works with many companies in the food and beverage industries.  And he founded and directed a nonprofit organization that for several years led chemistry camps for blind or visually impaired students. Dr. Brett Fiedler is a physical chemist with the University of Colorado Boulder’s PhET Interactive Simulations project. The team has been researching and designing new multimodal features for interactive science simulations.

Chronic Pain: A New Approach

On this week’s show, Beth speaks with Dr Afton Hassett, psychologist and pain researcher about her book, Chronic Pain Reset: 30 Days of Activities, Practices, and Skills to Help You Thrive. Not just a guide for evaluating pain and its triggers, her book offers straightforward and often fun strategies to move past chronic pain. Dr. Hassett is Associate Professor and Director of Pain and Opioid Research in the Department of Anesthesiology at the University of Michigan, and a principal investigator at the Chronic Pain & Fatigue Research Center there. Her book and research explore the key role that your brain plays in processing pain and how small, simple actions can make profound changes in how you experience chronic pain. Chronic Pain Reset is written for people with chronic pain and those who care for them.

COP28 Climate Summit: Pledges & Realities

Climate Change & COP28 (start time: 1:30) A major global climate conference is taking place now in Dubai, amidst a year of record-breaking heat, wildfires, floods and more around the world.  COP28 is short for the 28th Conference of the Parties of the United Nations Framework Convention on Climate Change. The aim of the conference is to have nations address climate change by pledging to cut greenhouse gas emissions (and actually following through), investing more in clean energy, and having richer nations help fund climate-adaptation measures in developing countries and especially vulnerable communities. Our guests today are Dr. Alice Alpert, a senior scientist at Environmental Defense Fund who previously served on the U.S. delegation to some COP conferences; and science journalist Tom Yulsman, who directs the Center for Environmental Journalism at CU Boulder.
