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.
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.

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.
Beth Bennett speaks with Claudia Tebaldi, a climate scientist at NCAR, about her work analyzing climate models to project climate change in the future. She addressed heat waves and local conditions and how these models can be used to make projections in these areas. Start time approx 5 min.

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.

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.

Nematode worms for studying Alzheimer’s (start time 4:57). Beth Bennett interviews Dr Chris Link from CU Boulder on his research into the genetic basis of Alzheimer’s Disease, ALS, and other neurodegenerative disorders.
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.
