Into The Unknown (Part 1)

Into The Unknown (starts at 7:57) What do we know about the universe, and how do we know we know it? Conversely, what do we know we don’t know, what don’t we know that we don’t know, and why not?

To help us unravel these age-old philosophical questions in the context of current science, our guest is Dr. Kelsey Johnson, who received her PhD in astrophysics from the University of Colorado.  Dr. Johnson is a Professor in the Department of Astronomy at the University of Virginia, and the former president of the American Astronomical Society. She is the founder of the Dark Skies, Bright Kids program, and wrote the children’s book Constellations for Kids. Her most recent book is Into The Unknown: The Quest to Understand the Mysteries of the Cosmos. In this episode, Dr. Johnson takes us into that unknown, and talks about what we know, what we might know, and what we might never know.

Autumn Insects and their Songs

Science & Songs of Katydids, Cicadas, etc. (start time: 3:08)  It’s the time of year to savor listening each night to the pulsating and clicking sounds of katydids, cicadas, crickets and other straight-winged insects, all crying out for a mate. Soon, with the first big frost, the songs, along with the arthropods themselves, will disappear. In this week’s show, a longtime arthropod expert, Tim McNary, talks with host Susan Moran about things like, who are these small yet very vocal insects? What’s their life cycle like? What body parts make those noises? What role do these vocal insects play in the broader ecosystem? McNary is a curator at the Gillette Museum of Arthropod Diversity at Colorado State University in Fort Collins. Previously, he worked at the U.S. Department of Agriculture in the field of grasshopper and locust management.

From Habitat Loss to Repairing Connectivity

Courtesy: Patagonia Works

Helping Wild Animals Roam (start time: 3:29) Wild animals, whether  buffalos or bats,  need space to move around–not just to survive, but to forage,  reproduce, migrate, and generally thrive as a species.  But it’s getting increasingly difficult for so many species to do this, thanks to humans breaking up their habitats to build roads, fences, housing developments, croplands, etc. Of course, climate change, pesticides, and other stressors compound the problem. In this week’s (fall fund drive) show, host Susan Moran interviews Hillary Rosner, a local environmental journalist and University of Colorado Boulder assistant teaching professor of journalism. Her debut book, called Roam: Wild Animals and the Race to Repair Our Fractured World (Patagonia Works), will be released next week. In her reporting, Hillary digs into some of the threats to wildlife here in the U.S. and elsewhere, as well as bold efforts by individual humans and communities to repair and connect landscapes enough to let many animal populations thrive. And in many cases, helping wildlife move also helps human communities become economically and socially stronger.

Science Journalism with Miles O’Brien // Acetaminophen and Autism

This episode features Miles O’Brien, a science journalist who has been a correspondent for PBS News and CNN. He talks about his experience breaking in to science journalism, past and current science reporting, public and political views of science, the value of scientific research, and some particular stories including beavers, prostheses, and climate change research in Antarctica. This feature is an interview by KBUT‘s Toni Todd and shared with us via Rocky Mountain Community Radio.

And we also have a report on the recent government claims about autism and use of acetaminophen (the active ingredient in Tylenol) during pregnancy, which is disputed by researchers and medical groups.   We provide the full transcript of the press conference held by SciLine of the American Association for the Advancement of Science with Brian Lee, a professor of epidemiology and biostatistics at Drexel University.

What About All Those Body Products We Buy?

On this week’s How On Earth, Beth spoke with two cosmetic chemists, hosts of the podcast The Beauty Brains. We touched on some basic questions I have regarding some of the universe of products, such as shampoos, body lotions and sun screens. Beauty Brains Perry Romanowski and Valerie George, are both veteran cosmetic product developers who have worked on some of the most popular beauty products in the world. They’ve written dozens of science articles and books. Their book, Beginning Cosmetic Chemistry is used in several college programs. You can find transcripts of their podcast episodes on their website.

Menopause, Hormone Therapy, Science

Menopause & HT (start time: 0:58)  It happens to every woman with a uterus who reaches midlife. Menopause is a major hormonal  transition that, although very challenging for some women, is natural, and (get this!) even  advantageous to civilization. Think grandmothers!  Yet menopause has been largely dismissed by the medical community. As a result,  too many women suffer through menopause in pain, shame,  and loneliness. In this week’s show, host Susan Moran  interviews Dr. Jen Gunter, a gynecologist and specialist in chronic pain medicine. She wrote the book  The Menopause Manifesto (2021), and she’s among a growing cadre of medical practitioners who are pushing to bring more information to women about what to expect during menopause and about treatment options, including hormones.

The (ever-changing) Scoop on Vaccines

On this week’s How on Earth, Beth describes recent developments in defunding NIH research and CDC limits on vaccine availability; then digs into vaccine safety and development with global vaccine expert, Dr Dr Kawsar Talaat. Dr Talaat is a physician who is board certified in Pediatrics, Internal Medicine and Infectious Diseases and whose research focuses on vaccines. She has worked on clinical trials for a variety of vaccines, including influenza, malaria, Ebola, and several gut bacteria. Currently, Dr. Talaat oversees COVID-19 vaccine trials in adults and children, and is Johns Hopkins Principal Investigator for the CDC Clinical Immunization Safety Assessment project.

Climate Change, Astronomy, Canine Astronauts

Climate change. Astronomy.  A canine astronaut. They intersect in our guest, astronomer and author Dr. Jeff Bennett. Among other things, we focus on climate change and policy – present and future.

Dr. Bennett got his Ph.D. in Astrophysics from the University of Colorado, and he served two years as a Visiting Senior Scientist at NASA Headquarters, where he was the first scientist hired within a science division specifically to leverage science missions for education. As an author, Dr. Bennett has written college textbooks in astronomy, mathematics, statistics, and astrobiology, and a freely available, interactive digital textbook about Earth and Space Science for middle- and high-school students.  He also has written popular books that include a series for children about an intrepid astronaut dog named Max, who goes to the Moon, Mars and elsewhere.

A particular topic we plan to delve into today with Dr. Bennett is regarding his book titled: “A Global Warming Primer: Pathway to a Post-Global Warming Future”.  A current issue is the EPA’s proposal to rescind the 2009 Greenhouse Gas Endangerment Finding. The comment period for the proposed rule change has been extended to September 22. Other issues include the Department of Energy’s recent report critical of climate change research (see rebuttals of the report by Dr. Bennett and others), and whether NASA will continue doing climate and other Earth-based science.

Wildfires in a Changing Climate

On this week’s show we replay an interview from two years ago with author John Valliant on his then-newly released book, Fire Weather, the story – and much more- of the groundbreaking wildfire that devastated the oil sands capital city of Fort McMurray in Alberta. Given the current outbreaks of Colorado wildfires, getting bigger and harder to contain each year, Valiant’s message of the changing nature of these horrifying disasters is ever more pertinent. Also, headlines on the evolving nature of science in another changing climate of federal oversight.
