KGNU - How On Earth

The Red PlanetThis week, Alejandro speaks with Leonard David, a space journalist who has written a new book Mars – Our Future on the Red Planet. In his book he discusses the plans of both NASA and private companies to send humans to the red planet. The book is a companion to a six-part television series from executive producers Brian Grazer and Ron Howard, and which premiered on the National Geographic Channel last month.

Titan, a moon of Saturn, rises above the rings of Saturn. Image courtesy of NASA/JPL Beyond Earth (start time 5:10) Many have dreamt of colonizing other planets. It’s been a staple of science fiction for decades. Most often, people imagine creating a colony of humans on Mars, where people would live on a cold, dry planet with a thin, unbreathable atmosphere. Mars, however, may not be the best destination for future human colonization. In fact, Titan, a moon of Saturn, may hold greater hope for extending humanity’s presence in the solar system. Either way, humans face tough but surmountable challenges as we move beyond Earth. As a planetary scientist, Dr. Amanda Hendrix is actively involved in the scientific research and future mission planning that will enable humans to settle on other planets. She’s the co-author, with Charles Wohlforth, of the new book Beyond Earth: Our Path to a New Home in the Planets. Listen to How On Earth’s Alejandro Soto’s interview with Amanda Hendrix, where they discuss the opportunities and challenges for human space exploration.

Max Boykoff Max Boykoff – Global Climate Talks – Moving Ahead With or Without US –  (entire show) While the world has held climate talks for 22 years (This is COP – Conference of the Parties — 22) and the Kyoto Protocol talks about climate change have been held for 12 years, this year’s October’s climate talks in Paris mark the first time that  “entry into force” has been achieved.  You might think of “entry into force” as the time when a critical number of nations are ready to develop global treaties regarding climate and pollution and its effects around the world.  The 1st world meeting ever to talk about “Entry into Force” on climate issues is taking place right now, in Marrakech, Morocco.  200 nations have gathered to discuss these issues.  The meetings began just before the US elections.  Now Donald Trump is President Elect, and he has signaled that he will pull back from many of the nation’s current plans to reduce pollution and combat climate change. To find out how this affects the world climate talks, up next we talk with Max Boykoff, speaking via Skype from the world climate talks in Marrakech Morocco.  Max Boykoff is a scientist at CU Boulder and director of the Center for Science and Technology Policy Research, which is part of the Cooperative Institute for Research in Environmental Studies at CU-Boulder.  He’s the author of a book on climate science and social response, titled, “Who Speaks for the Climate?”   Host/Producer/Engineer: Shelley Schlender Executive Producer: Beth Bennett    

The Science of Suggestibility (start time: 5:00) Scientists are learning more and more about how our expectations and beliefs influence how our bodies, including our neurochemistry, respond to pain and disease. The researchers are discovering that we are very suggestible creatures. But we are not all equally suggestible. Some of us can cure serious ailments even when we’ve knowingly taken a placebo remedy, but others can not. Herein lies a major puzzle that vexes drug manufacturers and medical practitioners. It’s a puzzle that has intrigued Erik Vance, a science journalist, since he nearly died from a severe illness when he was a toddler. His journey is detailed in a book that was just published today. It’s called Suggestible You: Placebos, False Memories, Hypnosis and the Power of Your Astonishing Brain (National Geographic).  Listen to How On Earth’s Susan Moran’s interview with Erik Vance.

Multitudes of Microbes (start time: 3:38): You may find it unsettling to learn that our human cells make up only half of our bodies. The other half is a bunch of microbes (in the neighborhood of 40 trillion), all living and reproducing in, and on, our bodies. What’s more, these invisible machines could have a powerful influence on your brain, and on your overall health. Ed Yong, a staff writer for The Atlantic, found it disconcerting at first to learn this when he researched his book called “I Contain Multitudes: The Microbes Within Us and a Grander View of Life.” The book, published earlier this year, explores the mysterious partnerships between humans, and many other species, and the mighty microbes with which we have co-evolved. Today we air the full phone interview that How On Earth host Susan Moran recently had with Yong. We played short clips of the conversation during our fall pledge-drive show last Tuesday. Thanks to you listeners who pledged! And thanks to Yong’s publisher, Ecco, an imprint of HarperCollins, for donating to KGNU several copies, which some generous members are now reading. This interview continues our series called “Our Microbes, Ourselves.” Hosts: Kendra Krueger, Susan Moran Producer: Susan Moran Engineer: Kendra Krueger Executive Producer: Beth Bennett Listen to the show:

This week’s pledge- drive show features a teaser introduction to Ed Yong’s new book I Contain Multitudes: The Microbes Within Us and a Grander View of Life. We play segments from the interview that host Susan Moran recently had with Yong, a science writer for The Atlantic. There still may be a copy left, so call now to have your own, with a pledge of at least $60 to KGNU. Call 303.449.4885. The book explores the role that invisible yet mighty microbes play in our lives, as well as the lives of so many species with whom they have co-evolved. Yong highlights the research of many scientists in this emerging field who are studying how our gut microbiome influences our brain chemistry, and our overall mental and physical health. The book deepens our understanding of the ecosystems within our bodies as well as the ecosystems in the natural world. Next Tuesday, Nov. 4, we will broadcast the complete interview with Ed Yong.

Denver Permaculture Guild (starts 3:30) staff and board members explain the goal of permaculture and guild’s annual workshops program taking place this weekend.       Autophagy – Courtesy Wiki Commons Ron Rosedale, MD, Explains Autophagy (starts 17:50)   The Nobel Peace Prize in Medicine has just been awarded to Japanese Scientist Yoshinori Ohsumi  for his discoveries about a process inside our cells known as autophagy.  Autophagy explains how a cell “cleans house” by recycling unessential components, either for food or for building blocks.   Mutations in autophagy genes can cause cells to keep fixing themselves up and living too long.  Think cancer cells.  Conversely, problems that get in the way of autophagy can lead cells to die too soon, such as in the neurologic diseases of Parkinson’s and Alzheimer’s.  The winner of this year’s Nobel Prize in Medicine was not available to discuss autophagy with us.  However, Shelley Schlender did speak with Ron Rosedale, a medical doctor who has been giving presentations about autophagy at science and health conferences for well over a decade.

Rosetta [feature starts at 5:27] The Rosetta Space Mission has been in flight for ever 12 years and will be ending with a dramatic crash this Friday morning around 10:40 UT (4:40 am Mountain time) – it’s an event that will be watched and talked about by people around the world. Rosetta is run by the European Space Agency, with contributions from NASA. The mission’s goals have been to study a comet to learn not only about how comets work, but what comets can tell us about the origins of the solar system, and perhaps connections to water and life. Rosetta was the first spacecraft to orbit and escort a comet as the comet approached and flew past the Sun, and Rosetta also carried a smaller spacecraft, named Philae, that performed the first landing on a comet. The Rosetta mission has a very strong Colorado connection, since one of the instruments – an ultraviolet spectrograph called “Alice” – was operated from the offices of Southwest Research Institute right here in Boulder.We have three members of the Rosetta team here in the studio to talk about Rosetta, comets, and the rather exciting ending planned for the spacecraft in just a few days. Our guests are Andrew Steffl from Southwest Research Institute, John Pineau from Stellar Solutions, and John Noonan who is a recent astronomy graduate from the University of Colorado and is working at Southwest Research Institute. There’s more information on the Rosetta Blog about how to follow the final events of the Rosetta mission.
