How the Glucocorticoid Receptor can Treat Asthma, Cancer, and More

The Glucocorticoid Receptor (starts at 5:30): We interview Dr. Miles Pufall who studies the glucocorticoid receptor, a protein in cell membranes that is the target of drugs used to treat a variety of conditions from asthma to cancer. Binding cortisol causes the receptor to be moved to the nucleus where it turns on (or off) numerous genes. One of the big questions is how does each cell type ‘know’ which genes should be targeted?

Electric Car Road Trips // Renewable Energy Nation . . . in 15 Years

Tesla Superchargers - Rural Arizona — Tesla Superchargers – Rural Arizona

Electric Car Road Trips (starts 3:42): We go on a road trip with How on Earth’s Shelley Schlender to see how all-electric vehicles are exceeding “range anxiety” by driving coast to coast, all on electricity. Along the way we talk with Boulder Nissan’s Nigel Zeid about regional plans to help more drivers “plug in” and with Hunter Lovins, head of Natural Capitalism Solutions.

Renewable Energy Nation (starts 11:53): Joel Parker talks live with NOAA scientist Alexander MacDonald and Christopher Clack, a mathematician at the University of Colorado-Boulder. They have developed a model that demonstrates how the entire U.S. can run on solar and wind power–with existing technologies, with no batteries, and at lower cost than today’s prices–within 15 years. For more information, see this video and these animations of:

Using the Microbiome to Determine Time of Death

Using the Microbiome to Determine Time of Death (starts at 5:40): This week on How on Earth, we speak with Jessica Metcalf, an evolutionary biologist, who studies bacteria, specifically the microbiome. One of her research interests is using molecular biology to address basic hypotheses about the role of microbes in corpse decomposition. The time since death, or postmortem interval, also known as (PMI), is important for criminal investigations because it can lead to the identification of the deceased and validate alibis. PMI is critical to both forensic science and pop culture (e.g. TV shows Bones, CSI). Recently she co-authored a paper published in Science, describing how various species of the microbiome can be used to accurately and repeatedly determine the post-mortem interval.

What You Can Do About Global Warming

What You Can Do About Global Warming (starts at 5:20): We interview Craig Hover, author of A World to Come Home To: Ending Global Warming in Our Lifetime. Craig is a licensed professional engineer with more than 30 years of engineering, project and facilities management, financial services and consulting. In his book he lays out a comprehensive vision of implementing sustainable strategies for reducing carbon emissions and reversing the current trends in climate change.

How the Brain Matures

The teenaged brain is wired differently than the adult.

Brains (starts at 4:35) This week on How on Earth we interview Professor Marie Banich, from the University of Colorado here in Boulder. Dr Banich uses cutting edge methodologies, particularly structural and functional MRI, to examine the role of the prefrontal cortex, as well as other brain regions, in executive function. Today she tells us about work that was recently funded by NIH to characterize how these systems change over the course of development.

Are GMOs Environmentally-friendly?

GMOs (start time 5:35) An interview with Dr Sharon Collenge, an ecologist at the University of Colorado. Dr Collenge is an advocate of using new genetic technologies to make slight modifications to plant genomes which can increase yield, protect against disease and reduce pesticide use.

This week on How on Earth, we speak with Dr Paula Hoffman, a neuropharmacologist – she’s scientist who studies what drugs do in the brain- who works on the genetics of alcohol and other drugs of abuse. Paula reviews the action of alcohol on different neurotransmitter systems of the brain then describes some of the genetic issues which predispose people to risk for becoming alcoholics. Finally she talks about research done in her lab which has resulted in preliminary understanding of genetic networks involved.

Pluto Flyby // Case of the Rickety Cossack

Pluto Flyby (start time 1:00): Joel Parker discusses the New Horizons mission from the command center live!

Case of the Rickety Cossack (start time 25:00): Beth Bennett talks to Ian Tattersall about his new book, a fascinating précis of the study of human evolution and some startling new findings showing that our species is one of many hominids in which natural selection mixed and matched various characteristics and abilities.

Aging//and not aging

Will we be able to reverse aging some day soon?

We talk with Dr Thomas Johnson about his long standing interest in aging and how he used a nearly microscopic worm to investigate this process. Recently, he has transitioned into using mice to identify genes influencing the aging process. Some of his findings have identified potential drugs to slow aging and keep us healthier as we live longer.
