Case-Against-Sugar-Book — Nature Fix 2 // Case Against Sugar Mar 16, 2017
Show notes

The Nature Fix. (starts 1:50) In this spring pledge drive show, we revisit the science show interview about the benefits of getting out in nature.

The Case Against Sugar. (starts 9:40) Best-selling science writer Gary Taubes discusses his new book, which explains what happens when industry funds science . . . and controls the strings to science. It’s a not so sweet story with some bitter truths. Taube’s new book shares some cloak and dagger moments, such as when a researcher in the Denver Metro area uncovered a load of documents from the mid-20th century about tooth decay. The documents showed how the sugar and processed food industry funded dental studies – – and worked with national dental associations to publish research that determined that sugar does not cause cavities. Additionally, Taubes’s new book includes well-documented reasons he argues that it’s sugar consumption, not salt, that leads to high blood pressure. And Taubes contends that sugar consumption, not eating fat, leads to obesity and diabetes.

NSO eclipse announcement — Eclipse 2017 Mar 03, 2017
Show notes

Eclipse 2017 (start time 5:56): This summer America will experience its first total solar eclipse in almost 30 years. How on Earth’s Alejandro Soto speaks with Dr. Claire Raftery from the National Solar Observatory (NSO) about the upcoming eclipse. Dr. Raftery talks about the science and history of eclipses, the best ways to view the eclipse in August, and how to safely look at an eclipse. Fortunateley, viewing the eclipse only requires a few simple steps and some inexpensive tools, so anyone can experience this exciting event — as long as they can drive to a place in the path of the eclipse. Dr. Raftery also talks about the NSO’s webseries about the eclipse and our Sun. Finally, there is the opportunity to participate in solar science research by taking part in the Citizen Cate program, a citizen science project that uses telescopes scattered along the path of the eclipse to collaboratively monitor the entire eclipse event.

Show notes

Today’s feature has How on Earth’s Beth Bennett talking with Dr. Mike Shanahan, a biologist who has a degree in rainforest ecology. He has lived in a national park in Borneo, bred endangered penguins, and investigated illegal bear farms. His writing has appeared in The Economist, Nature, and The Ecologist, and he also was the illustrator for the book: Extraordinary Animals: An Encyclopedia of Curious and Unusual Animals. His interests delve into what people think about nature and our place in it. Beth had a chance to talk with Dr. Shanahan about his new book: Gods, Wasps and Stranglers: The Secret History and Redemptive Future of Fig Trees.

NatureFix_2 with frame.jpg — The Nature Fix Feb 14, 2017
Show notes

Your Brain on Nature (start time: 5:49): You may think it’s a no-brainer: that nature is good for your mental and physical health. After all, a walk in the woods or even an urban park brightens your outlook on life, at least for a little while. Turns out, the notion that being outside in nature boosts our mood, and even our creativity, has historical roots at least as deep as Aristotle. A new book by journalist Florence Williams explores the history of our biophilia, and particularly emerging neuroscience that reveals just how our bodies and minds are affected by getting out in the natural world. The book is called The Nature Fix: Why Nature Makes Us Happier, Healthier, and More Creative (Norton, 2017). The book stemmed from an article Williams wrote in National Geographic. A former Boulder resident, Williams will return to Boulder to give a talk about her book on Tuesday, February 28th, at the Boulder Book Store, at 7:30 p.m. She’ll also speak in Denver, on Wednesday, March 1st, at Tattered Cover Book Store, at 7:00 p.m.

Citizen Science — Citizen Science Feb 07, 2017
Show notes

Citizen Science (start time: 5:32): For those who would love to track birds and other creatures or to test drinking water quality in their community, for instance, but think it would require a degree in science to contribute to important scientific discoveries, our guest today aims to set the record straight. Dr. Caren Cooper is an associate professor of Forestry and Environmental Resources at North Carolina State University. An ornithologist, she studies bird ecology, conservation and management through the use of citizen science. She wrote a recently published book called Citizen Science: How Ordinary People are Changing the Face of Discovery. It highlights many examples of inspiring and important citizen science projects, including a meteorological-forecasting program and some others here in Colorado. Dr. Cooper is also director of research partnerships at SciStarter.com, which connects interested volunteers to a diverse range of research projects that they can work on. Additional citizen science programs can be found at the Cornell Lab of Ornithology and Audubon Society’s Rockies chapter.

Show notes

Artwork credit: MDMA trial participant Allison Heistand-Phelps

This week on How on Earth host Susan Moran interviews two investigators of FDA-approved clinical trials testing the efficacy and safety of the illegal drug MDMA — known in an altered form as Ecstasy or Molly — as a treatment (along with psychotherapy sessions) for Post-Traumatic Stress Syndrome. Our guests are Marcela Ot’alora and Bruce Poulter, investigators of the Colorado trial. Marcela is a licensed psychotherapist and Bruce is a registered nurse with a masters degree in public health

PTSD is an anxiety disorder that affects up to one in 12 people in the United States, and it’s at least as common in some other countries. It is a serious, and costly, public health problem. If the trials are successful, MDMA, which has its critics, could become commercially available as a medically prescribed treatment by 2021. The trials are being funded by a nonprofit organization, the Multidisciplinary Association for Psychedelic Studies (MAPS), which promotes careful and beneficial uses of psychedelics and marijuana.

Dr. David Grinspoon (photo by Lawrence Cheng) — Earth in Human Hands – Shaping our Planet’s Future Jan 11, 2017
Show notes

Dr. David Grinspoon
(photo by Lawrence Cheng)

Sometimes when we are having personal or health problems, it helps to get an outside perspective: talk to other friends who have experienced similar problems and how they dealt with them, and other friends about how they avoided those problems. Talk to experts. Then using all that input, we try to make the best choice to solve the problems and to live a long and happy life. This is perhaps the situation we find ourselves in now with the health of our environment and the long-term viability of the human race. So where to we look for that “outside perspective” and expert help? The answer may be: look to other planets and talk to those who study them. This is the approach astrobiologist Dr. David Grinspoon takes in his new book: “Earth in Human Hands: Shaping Our Planet’s Future”. Dr. Grinspoon is a senior scientist at the Planetary Science Institute, an adjunct professor at the University of Colorado, and in 2013 he was appointed the inaugural Chair of Astrobiology at the Library of Congress. We had a chance to talk with Dr. Grinspoon about how he compares Earth’s story to those of other planets, and how our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective.

The podcast of the show is below, and you also can hear the extended interview here.
