Cancer Biology // Oil&Gas Health Impacts

Today’s show offers two feature interviews:
Adaptive Oncogenesis-978-0-674-98596-4-frontcoverNew 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: 12:54) Many people living all along the Front Range are familiar with the sights and smells of oil rigs operating in fields near their homes and schools.  State regulators argue  that this convergence of people and oil rigs is safe. But many nearby residents and scientists are concerned about the potential health impacts of these drilling operations so close to residential neighborhoods and schools. Our guest, Dr. Lisa McKenzie, is the lead author on a new study that adds some critical evidence to back concerns of residents. It found that for people living within 500 feet of a well, the risk of their getting cancer over the course of their lifetime is eight times higher than the upper acceptable levels established by the federal EPA. Dr. McKenzie is an assistant research professor at the Colorado School of Public Health at the University of Colorado Anshutz Campus. She discusses the study and its implications with hosts Daniel Glick and Susan Moran. (Here is our interview with Dr. McKenzie a year ago about a related study.)

Urban Air Pollution: A new culprit

It’s the endless stream of tailpipes on the L.A. freeway which  causes that unsightly smog, nagging cough and chronic respitory problems, right?  Perhaps not any more, a new scientific study helps build the case that the major culprit may now be purchases made at the corner drug store or hardware store.  Chip Grandits speaks with Dr. Brian McDonald of NOAA about perhaps changing tactics for the next stage in the human race’s campaign to keep the air clean and healthy in both the indoor and outdoor environments of the urban areas many of us call home.

A couple headlines focus on related aspects of the changing climate in our Alpine environment and what it really means.  Does it seem like spring comes earlier every year, or is that just your imagination?  Well, the science says probably not, especially if you live in the Northern latitudes.  Science journalist Tom Yulsman, who writes about climate change and beyond in his blog ImaGeo for Discover magazine,  offers a headline  the declining snowpack in the Rockies.
