KGNU - How On Earth

DNA Superconductors (Starts 1:00) Scientists are harnessing DNA to make electronic components at the nano-scale. Western Rewilding Network (Starts 3:50) Researchers at Oregon State University are urging the U.S. to set aside 500,000 square kilometers for a Western Rewilding Network that would include wolves and beavers as part of ecosystem restoration.  Their research appears today in the journal BioScience. What Your Food Ate: How to Heal Our Land and Reclaim Our Health (Starts 9:05)  KGNU News Director Shannon Young speaks with authors David R. Montgomery and Anne Biklé for the science behind the time-honored adage that the roots of good health start on farms . . . and how modern agriculture needs to change to restore those roots.

Colorado Cafe Sci (starts 1:00)  happens monthly, in Denver. cc Wikimedia Alcohol and Alcoholism Recent News (starts 2:49) We look at recent science about alcohol consumption, including a study that indicates as little as 3 glasses of wine a week is associated with buildups of iron in the brain — a risk factor for brain disease, increased binge drinking among pregnant women, and a new study about genetic characteristics associated with alcoholism. Beth Bennett Discusses the Biology of Alcoholism, Homeostasis and Allostasis (starts 5:35) Discussion includes a reference to the studies about yeast and entropy with Matthias Heinemann.  Go here to listen to the entire extended interview (45 minutes long) and go here for an extended version transcript Executive Producer: Beth Bennett Show Producer: Shelley Schlender Additional Contributions: Joel Parker & Benita Lee

Lake Mead’s “bathtub ring” (July 2022)Photo credit: Tom Yulsman This week on How On Earth: Colorado River Basin Crisis (start time: 5:31–scroll down for arrow) The Colorado River is the life blood for about 40 million inhabitants. And it’s in dire straights. The river’s two reservoirs, Lake Mead and Lake Powell, are at historically low levels, due primarily to climate change and overuse. The water-supply crisis is affecting Colorado and six other states, as well as some 30 tribes, that rely on the Colorado River for water and electricity. Last month the federal government ordered the seven states to jointly come up with a plan to dramatically cut their consumption from the river. They have until mid-August to deliver–or they’ll face mandatory cuts. Host Susan Moran discusses with two guests the underlying causes of the water crisis, what’s at stake, and potential solutions. Jennifer Gimbel is a senior water policy scholar at the Colorado Water Center, located at Colorado State University. Formerly she was an undersecretary of the Department of Interior, and executive director of the Colorado Water Conservation Board.  Tom Yulsman is a science journalist focusing on climate change. He runs the ImaGeo visual blog for Discover magazine, and he is director of the Center for Environmental Journalism at CU Boulder.

This week on How on Earth, Beth talks with Dr Seven Hussey about his recent book, Understanding the Heart: Surprising Insights into the Evolutionary Origins of Heart Disease—and Why It Matters. Following his early (34 years old) heart attack, he delved into alternative therapies to heal his heart. In the book he lays out a comprehensive vision of the cardiovascular system and alternative therapies for heart disease. Executive Producer: Joel Parker Show Producer: Beth Bennett Listen to the show:
