Pesticides and Health Impacts

kale photoA Consumer’s Guide to Pesticides in Produce (starts  7:55) You may be wondering if you washed the strawberries, blueberries or kale that you had for breakfast this morning enough to rid them of residue of potentially harmful pesticides. That is, if they were conventionally, not organically, grown. According to the U.S. Department of Agriculture, more than 200 different pesticides remain in some form on popular fruits and vegetables that Americans eat every day. And before testing all the produce, the USDA thoroughly washes and peels them. Such tests show that simply washing produce does not remove all pesticides. In a recently released report, as part of its “Shopper’s Guide to Pesticides in Produce,” The Environmental Working Group ranked the pesticide contamination of 47 popular fruits and vegetables. Its analysis, which was based on results of nearly 50,000 samples of produce that the USDA tested, found that 70 percent of produce contains pesticide residues. But don’t despair: There is also good news in the report. Sydney Evans, a science analyst at EWG, and Liza Gross, an independent investigative reporter, speak with host Susan Moran about the EWG report and the broader societal and environmental implications of pesticides. See Liza Gross’ articles on pesticides and other issues.

This View of Life: Completing the Darwinian Revolution

9781101870204This View of Life (starts 6:56) In this episode of How on Earth, we talk with David Sloan Wilson, an evolutionary biologist with a special interest in human biocultural evolution. Dr. Wilson is Distinguished Professor of Biology and Anthropology at SUNY Binghamton, and president of the Evolution Institute as well as editor in chief of its online magazine This View of Life.  It is not just about biology, these ideas are formed by decades of research and drawing on studies that cover topics from the breeding of hens to the timing of cataract surgeries for infants to the organization of of an automobile plant.  Last month he published his latest book, also titled This View of Life to present a comprehensive case for what he calls Completing the Darwinian Revolution.

The Goodness Paradox – Full Interview

cover-Goodness ParadoxThe Goodness Paradox (Starts 5:22): On this week’s show we play the full interview with Richard Wrangham, a primatologist at Harvard University, about his new book, The Goodness Paradox: The Strange Relationship Between Virtue and Violence in Human Evolution.  Wrangham discusses with How On Earth hosts Susan Moran and Chip Grandits how, and why, homo sapiens evolved to be both peaceful and violent (less reactively aggressive and more proactively aggressive, like our bonobo ancestors), and what it bodes for the future of human civilization. On the pledge-drive show last week we played short snippets of the interview. And thanks to our listeners who pledged, some of whom received a copy of The Goodness Paradox. And thanks again to Pantheon Books for donating them.

The Goodness Paradox // Pledge Drive

cover-Goodness ParadoxThe Goodness Paradox (Teaser): Today’s spring pledge-drive show features brief clips from a recent interview with Richard Wrangham, a primatologist at Harvard University, about his new book, The Goodness Paradox: The Strange Relationship Between Virtue and Violence in Human Evolution.  Wrangham discusses with How On Earth hosts Susan Moran and Chip Grandits how, and why, homo sapiens evolved to be both peaceful and violent (less reactively aggressive and more proactively aggressive, like our bonobo ancestors), and what it bodes for the future of human civilization. We will air the full interview on the March 19 science show. Thanks to Pantheon Books for offering KGNU several copies of Wrangham’s book. And thank you to listeners who pledged and received a copy of the book, and to those who have helped power this community radio station for years. If there are any copies of The Goodness Paradox remaining next Tuesday you can call in then and become a member for $60 or more. Or go to kgnu.org and pledge, or increase, your support. We couldn’t do it without you!

Tagging the Bugs that Carry Antibiotic Resistance

Antibiotic Resistance

Antibiotic Resistance

In this week’s show, Beth interviews Dr. Ivan Liachko, CEO and Co-Founder of Phase Genomics, a startup biotech company recently funded, in part, by the Bill and Melinda Gates Foundation. The company is using a new technology that allows researchers to pair plasmids, which are small non-chromosomal pieces of DNA, with the bacterial species carrying them. This is key to identiying the species in the microbiome that carry antibiotic resistacne genes. In the following interview, which starts at about 6:00 Dr Liachko describes the method and its implications. You can see more about the technology at their website.

In this week’s show, Beth speaks with William Hollander, and Kevin Miller, of QalibreMD, a Boulder startup focused on transforming MRI technology. Traditional MRI scans can result in a large differences between readings on different equipment. The results can be costly and misleading, as conditions like cancer can go undiagnosed or misdiagnosed.The interview starts ~5’30”, for more information you can see their website.

The Science of Exercise Recovery

Good To GoAthlete’s Guide to Recovery (starts at 5:39): Colorado is riddled with athletes, many of them incessantly chasing the latest recovery products and services that will enhance their performance — from Gatorade and other ubiquitous sports-recovery drinks, to supplements, to compression boots, to cryochambers, to good old-fashioned massages. How solid is the solid the science behind the multi-million marketing campaigns? Christie Ashwanden, a former pro cyclist, runner and skier, is also the lead science writer at FiveThirtyEight, and her new book explores the scientific research, the snake oil, and common sense practices, in the world of exercise recovery. Good to Go: What the Athlete in All of Us Can Learn from the Strange Science of Recovery (Norton), was just published today. Christie will also speak about her book tonight at the Boulder Book Store, and tomorrow in Fort Collins at Old Firehouse Books.
