Kgnu - How On Earth

This week on How on Earth, Beth finishes up her interview with Professor Doug Seals, aging researcher. He explains the role of vascular damage in heart disease and how lifestyle choices such as exercise and diet can maintain healthy vasculature. In addition, he discusses some of his experiments in older humans with supplements and pharmacologic agents such as mito-Q, NAD+ supplementation and cur cumin. For more detail, visit his lab website (https://www.colorado.edu/intphys/research/cardiovascular.html) or the Healthy Aging site (https://healthyagingproject.org/).

This week's How on Earth guest, Dr Doug Seals, researches vascular aging. Several events occur as we age that conspire to damage blood vessels, culminating in what is popularly known as hardening of the arteries. But lifestyle modifications to exercise and diet can prevent and even reverse this trend. This week's show gives background and mechanisms of this aging; next week's episode will delve more deeply into solutions and interventions.

We offer two feature interviews on this week's show: Health Impacts of Wildfire Smoke (start time: 4:22) It's peak wildfire season. Smoke from forest and grass fires contains particulates that can irritate eyes, throat and lungs -- especially in children, the elderly, and people already suffering from asthma, allergies, heart disease. How On Earth host Susan Moran interviews Anthony Gerber, MD/PhD, a pulmonologist and an associate professor of medicine at National Jewish Health and the University of Colorado, Denver, about the medical risks of breathing smokey air and what people can do to minimize the impact. The Colorado Department of Public Health and Environment also offers info and warnings on air quality in Colorado. Detained Migrant Children Suffer Medically (start time: 17:02) Since April, when the Trump administration's controversial zero-tolerance policy went into effect to crack down on families crossing the border illegally, more than 2,300 migrant children have been separated from their par

We present another part of our interview with Michael Pollan about his book “How to Change Your Mind:  What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression and Transcendence”.  It is an investigation into the medical and scientific revolution taking place around psychedelic drugs, and the spellbinding story of his own life-changing psychedelic experiences.  Books like “How to Change our Mind” are starting to “alter the state” of awareness about modalities that are outside the conventional box of standard medical treatments for mental health problems.  And there are other ways this wave of new awareness is heading into our communities. We also talk with Boulder Psychiatrist Dr. Will Van Derveer, who leads the Integrative Psychiatry Institute.  They will hold a professional conference this October 19-21 in Boulder. Their goal is to educate more health practitioners about how body imbalances, such as gut challenges and mold infections, along with undiagnosed trauma o

This week on How on Earth, Beth talks to author Dr Marc Bekoff, Professor Emeritus, CU Boulder. His new book has the wonderful title of Canine Confidential.

Junk Raft (starts 6:20) Marcus Eriksen discusses what can and cannot be done about the "plastic smog" of microscopic debris permeating the world's ocean, from the state-sized floating islands of plastic in the Pacific, to the microscopic debris that sinks all the way down the the deepest parts of the Pacific, OR gets eaten and into the food chain.  Eriksen is author of the book Junk Raft, recounting his adventures when he sailed the Pacific from L.A. to Hawaii on a raft made of garbage to bring attention to the issue. The Green Reaper (starts 19:10) Elizabeth Fournier, a mortician from Oregon, is known to some as "The Green Reaper." She offers and advocates for natural burial services for those who want to extend their environmental ethos from life on into death.

In 2015, the New Horizons Spacecraft flew past Pluto. Because Pluto is so far away, it took nearly 10 years of travel for the spacecraft to reach that distant dwarf planet -- and that was after a decade of work to get the spacecraft to the launch pad. Planetary scientists Alan Stern and David Grinspoon have written a new book, called: “Chasing New Horizons: Inside the Epic First Mission to Pluto”. The book tells the story of developing and operating the New Horizon mission. How on Earth’s own Joel Parker is also a scientist on the New Horizons mission, and he had a chance to chat with Alan and David about their book. Last week we heard the first part of this interview. In today’s show, we present Part 2 of that interview.  You can also listen to the full extended interview.

Today's show offers two feature interviews: New Theory of How Cancer Evolves Inside Us (start time: 0:58): It is commonly known that cancer afflicts old people more than youth. Conventional wisdom has held we get cancer with age largely because we accumulate lots of genetic mutations over many years, and it’s the mutations that cause cancer. Our guest, Dr. James DeGregori,  deputy director of the University of Colorado Cancer Center, discusses with host Susan Moran his new theory--one that challenges conventional wisdom--about why and how we get cancer. In his new book, called Adaptive Oncogenesis: A New Understanding of How Cancer Evolves Inside Us, DeGregori argues that cancer is as much a disease of evolution as it is of mutation. Mutated cells outcompete healthy ones in the ecosystem of the body’s tissues. Dr. DeGregori is a professor in the Department of Biochemistry and Molecular Genetics at the University of Colorado Anschutz Medical Campus. Studying Health Impacts of Oil&Gas Wells (start time: 12:5

As part of the Conference of World Affairs, which is being held this week at the campus of the University of Colorado, Boulder, we are speaking today with astrophysicist Adam Frank. Frank is a professor at the University of Rochester, where he studies the final stages of evolution for stars like the sun. He is also the author of an upcoming book, “Light of the Stars: Alien Worlds and the Fate of the Earth”, which will be published in June of this year. We spoke with Frank about ideas from this new book, including how the science of astrobiology can provide insights into how humanity can address planetary scale challenges like climate change.

Hacking the Planet (start time: 10:24): It’s tough to wrap one’s mind around just how monumental and consequential the problem of climate change is. So dire that scientist and engineers for years have been exploring ways to “hack” the planet--to manipulate the global climate system enough to significantly reduce planet-warming gases or increase the Earth's ability to reflect solar radiation. This audacious scheme, called geoengineering, only exists because many scientists think that human behavioral change, industry regulations, international treaties and national legislation, have not done enough -- can not do enough – to keep us from careening toward climate catastrophe. Our guests today have given this huge challenge a lot of thought and some research. Dr. Lisa Dilling is an associate professor of Environmental Studies at CU Boulder and a fellow at the Cooperative Institute for Research in Environmental Sciences, or CIRES. Dr. David Fahey is a physicist at the National Oceanic and Atmospheric Administratio
