The Tumor Microbiome Can Affect Cancer Survival

On this week’s show Beth speaks with computational biologist Justine Debelius about the role of the microbiome. We first discussed a study she was involved in recently that identified how changes in colon cancer tumors can affect survival. Then, she described a large collaborative project she is currently working on to identify factors influencing the development of the microbiome in children and how that affects them later in life.

Viruses are Us!

In this week’s science show Beth talks with genome biologist Ed Chuong of CU Boulder’s innovation incubator, the Biofrontiers Institute. Ed takes us for a whirlwind tour of the evolutionary history of these viral invaders of our genome, and some examples of how they can simultaneously be friend and foe. Teaser, did you realize that the genes that allow the formation of the placenta, the organ that nourishes human (and other mammal) fetuses, came from viruses!

Animal Pandemics?

On this week’s How on Earth, Beth talks with author and science journalist Liz Kalaugher, about her new book, The Elephant in the room:How to Stop Making Ourselves and Other Animals Sick. Think about it this way: When new diseases spread, news reports often focus on wildlife culprits–rodents, monkeys and mpox; bats and COVID-19; waterfowl and avian flu; or mosquitoes and Zika. But, as Liz points out, we see it often works the other way around–humans have caused diseases in other animals countless times, through travel and transport, the changes we impose on our environment, and global warming. In her deeply researched and often entertaining book, Liz introduces the wildlife we have harmed and the experts now studying the crosscurrents between humans, other animals, and health.

Measles: To Vaccinate or Not?

On this week’s show, Beth talks with Brianne Barker, Associate Professor of Biology and Director of Undergraduate Research at Drew University. Dr Barker studies innate immune responses – these are the initial, non-specific actions taken by the immune system – to fight off retroviruses such as HIV (the AIDS virus). We discuss the measles virus, how it gets into cells, travels through the body to cause its many symptoms, which can be long-lasting and even lethal, and its frightening ability to wipe out, or erase, much of the accumulated memory of the immune system to previous infections. For an even deeper dive into this dangerous virus, you can hear Dr Barker and other virologists go into greater detail here.

Train Wolves AND Humans to Coexist

On today’s show, Beth speaks with two experts on animal behavior and training about the wolf reintroduction project in Colorado – wins and losses. Mary Angilly is an advocate for force-free, evidence-based training in dogs and other animals. For decades Marc Bekoff has researched animal behavior, cognitive ethology (the study of animal minds), behavioral ecology, and compassionate conservation, and he has written extensively on human-animal interactions and animal protection.They have collaborated on essays involving problems faced by both wolves and humans in reintroduction projects. In this episode, they discuss some interesting and innovative solutions.

How a Soil Bacterium Can Affect Mental and Physical Health

On today’s show, Beth speaks with CU scientist Christopher Lowry. Dr. Lowry’s research program at CU Boulder focuses on understanding stress-related physiology and behavior with an emphasis on the microbiome-gut-brain axis. He describes his recent finding that exposure to a harmless soil bacterium protects mice from the weight gain and inflammation stemming from a diet much like the average American one, that is, high in fat and sugar. You can also hear about another CU Boulder group’s recent finding on the protective role that being in ‘greenspaces’ can provide.

What’s Up with the Polio Vaccine?

Today on How on Earth, Beth speaks with Professor Vincent Racaniello of the Columbia University Medical Center. He has been studying viruses, particularly the polio virus, for over 40 years. Professor Racaniello is passionate about teaching virology to the World. His virology lectures can be found on YouTube. He blogs and produces the podcast ‘This Week in Virology’. We cover the history of the different polio vaccines and why the oral vaccine has contributed to the resurgence of the disease in underdeveloped populations in for example, Africa, and recently, Gaza. But it’s popping up here, in the developed nations also. You’ll also hear from How On Earther Tom Yulsman speaking with author and photographer Jon Waterman about his recent book on the effects of climate change in the Arctic.

Opiate Epidemic Update from 2024

In today’s show Beth reviews the latest data on the opiate epidemic in Boulder. You’ll hear from a pharmacologist who studies substance abuse, a DEA agent who oversees the task force on fentanyl, and our state senator who discusses legislation at the state level, as well as a story on a novel, implantable device to monitor for overdoses and autonomously inject the antidote – naloxone.

Move Your Body!

On today’s show Beth plays portions of a chat (full version here; actual talk starts at 1 minute in) she had with Katy Bowman who is a nationally-known biomechanist, author, and movement educator. They spoke at the Boulder Bookstore, where Katy discussed her new book, My Perfect Movement Plan. Bowman combines big-picture lessons on biomechanics, kinesiology, physiology, and natural human movement with simple and practical solutions and exercises to get all your body parts moving better. Her ‘Movement is Nutrition’ approach addresses the need of our bodies for a wide variety of daily movements in order to work well. Building off the idea that movement is more than exercise, Katy wants to us to create a movement diet that will provide both macro- and micronutrients that the body needs in order to stay well and work well.
