What You Can Do About Global Warming

solar-panels 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.

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?

Genetically-modified crops

Genetically-modified crops

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

PlutoPluto 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?

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.

Einstein, Niels Bohr and Grandmothers…a Fairy Tale!

An educator and perfomer, Len Barron first developed a piece about Einsteina and Bohr as a one man show, but then decided to evolve the project by enlist the help of 8 grandmothers to tell the story with their own added pizazz.  Not only was lively performance produced, but a process and experience was shared.  This process was captured by documentary film maker Robin Truesdale in a film coming to the Dairy Center this weekend entitled A Beautiful Equation.  Both Robin and Len have joined us today in the studio to tell us more about the film, the process, the scientists and the grandmothers.

4:30pm and 7:30pm Sunday May 31st at The Dairy Center for the Arts in Boulder, CO

Ancestors in Our Genome

9780199978038We speak with Eugene Harris, Professor in the Department of Biological Sciences and Geology at Queensborough Community College – part of  the City University of New York – about his new book,  Ancestors in Our Genome. In this feature, we discussed the methods used by molecular anthropologists to determine human evolution from our primate ancestors and several fascinating examples of the application of these techniques, including a discussion of the rise of lactose digestion in northern Europeans.

Other Rocky Planets are Common!

Kepler444 We talk with astronomer Travis Metcalfe about finding the oldest known planetary system in the Galaxy, and what it means about the formation of planets, the possibilities of extraterrestrial life, and how does one actually find planets around other stars? Headlines include switches in the man-made biological organisms that could possibly be used for bioterrorism, and the finding that chronic malaria infection in migrant great reed warblers  damages telomeres, shortening life in both the adult bird and its offspring.
