Race Science: Then & Now Jun 20, 2023
Show notes

Race Science’s Legacy (start time: 0.57): We like to think of science as neutral, beyond politics. But of course it isn’t. After all, science is a product of the political landscape in which it arises. Despite the fact that decades ago the United Nations declared that race has no biological basis, science has continued to be co-opted to justify racial inequality–namely, the intellectual superiority of whites. Recently scientists have been reckoning with the damaging legacy of race science. In this week’s show host Susan Moran interviews two journalists: Angela Saini, a science journalist and author of several books, including Superior: The Return of Race Science; and Ashley Smart, senior editor of Undark magazine, and associate director of the Knight Science Journalism Program at MIT. See Undark’s Long Division Project, a series of articles exploring the persistence of race science.

Boulder Society for Scientific Exploration Jun 13, 2023
Show notes

Paul Sperry in Egypt – c Paul Sperry

NCAR and NOAA open for visitors (Starts 1:00) COVID pandemic rules were lifted earlier this year, so Boulder’s National Center for Atmospheric Research and National Oceanic and Atmospheric Administration are once again open for public tours.

LASP Artist in Residence Applications due July 21 (starts 2:12) CU-Boulder’s Laboratory for Atmospheric and Space Physics is accepting applications for an Artist in Residence program, where three artists will shadow a scientist or engineer, to learn about the work done at LASP, and to produce artwork inspired by their time at LASP.

Boulder Society for Scientific Exploration (starts 3:05) has many fans among well-known scientists, but it also has many critics, who charge that much of the society’s work promotes pseudo-science. We speak with Paul Sperry, Co-Founder of the Boulder Society for Scientific Exploration, about why he values “fringe science” and how be believes more intuitive approaches to Life and science can benefit scientific discovery. We also discuss the next SSE talk on June 23rd, and how to reserve a seat.

Fire in a Hotter World Jun 06, 2023
Show notes

In this week’s How on Earth, Beth speaks with author John Vaillant about 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.

Honeybee Trials and Tribulations May 23, 2023
Show notes

This week on How on Earth, Beth replays in interview with Professor Mike Breed, who has been studying social insects, including ants and bees, at the University of Colorado here in Boulder, for decades. She spoke with him last year about the fascinating biology of these important pollinators, in an interview that is still timely, because the many problems facing honeybees, and other bees are continuing to mount. He describes the challenges these important insects face in the modern world, and what we can do to protect them.

Gold Lab Symposium on Science and Health May 16, 2023
Show notes

CU-Boulder’s 14th annual Gold Lab Symposium on the Science of Health takes place this Thursday and Friday at CU-Boulder’s Muenzinger Auditorium and on line. You can sign up for the symposium here. In today’s show, Larry Gold, founder, scientist and entrepreneur, talks about some key scientific discoveries being discussed at this year’s symposium, along with the implications for health and health care.

This week, we focus one on of the new findings that will be discussed at the Symposium, in a talk by scientists. Andreas Beyer & Argyris Papantonis
The talk is titled, “Living in the Fast Lane: Accelerated Copying of Genetic Information with Aging.” For more about the science paper from Nature related to this topic, go here.

Your Brain On (and off) Chronic Pain: Part I Apr 11, 2023
Show notes

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
