American Gut Project

american-gut-project-stepsamerican-gut-project-steps-151029The American Gut project is the largest crowd-sourced project ever: to date, over 80.000 participants have contributed fecal, skin, or oral samples. The ambitious goal is to characterize the microbiota of as many individuals as possible to identify the diverse species living in and on us. Beth interviews Dr Embrietta Hyde, Project Manager of the Gut project about results and progess.

Earth in Human Hands – Shaping our Planet’s Future

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.

Forensic Plant Science: CSI for Real!

plant-scienceBeth interviews Drs Jane Bock (starts at 16:35) and David Norris (starts at 7:10), co-authors of Forensic Plant Science, the application of plant science to the resolution of legal questions. A plant’s anatomy and its ecological requirements are in some cases species specific and require taxonomic verification; correct interpretation of botanical evidence can give vital information about a crime scene or a suspect or victim. They describe their entry in to the field and some interesting cases.

Where is climate science research heading?

bleached-coralThis week on How on Earth Beth interviews two NOAA scientists who study climate change. Joanie Kleypas is a marine ecologist who investigates how rising atmospheric carbon dioxide affects marine ecosystems. She is a self-described optimist who is committed to finding solutions to the “coral reef crisis.” Pieter Tans he has led the Carbon Cycle Greenhouse Gases group at NOAA since 1985. This group has maintained NOAA’s Global Greenhouse Gas Reference Network, producing the most widely used data of atmospheric CO2, CH4, and several other greenhouse gases and supporting measurements.

Biodiversity Matters // Scientists Implore Trump

Gillian Bowser, research scientist, CSU

This week’s show offers two features:
Global Biodiversity (start time: 1:22): Scientists, NGOs and government representatives from nearly 200 countries have been gathering in Cancun, Mexico, for the UN Biodiversity Conference, known as COP13. They’re meeting to promote protocols and strategic actions related to biological diversity, climate change, food security, and even citizen science.  Gillian Bowser, a research scientist at Colorado State University, has studied international climate and biodiversity conventions, while working on issues such as women in sustainability, as well as citizen science. She discusses with host Susan Moran the importance of COP13, and the impact of citizens in scientific studies, such as identifying and tracking butterflies, birds and other species.

Scientists’ Letter to Trump (start time: 12:09) Last week roughly 800 earth and planetary scientists, as well as energy experts, sent an open letter to president-elect Donald Trump, urging him to take six concrete steps to address climate change and to help protect “America’s economy, national security, and public health and safety.” Trump has called global warming a concept created by China to make U.S. manufacturing non-competitive, and he has picked a climate change denialist to lead the Environmental Protection Agency. Many scientists fear that a Trump administration will drastically decrease federal funding for climate research. Indeed, the Trump transition team has already issued a questionnaire to the Department of Energy to identify employees and contractors who have worked on climate change research. Alan Townsend, an ecologist at the University of Colorado Boulder and one of many Colorado scientists who signed the letter, discusses these issues with hosts Maeve Conran and Susan Moran.

Colonizing Mars?

The Red Planet
The Red Planet
This 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.

Beyond Earth: Our Path to a New Home in the Planets

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 – Global Climate Talks – Moving Ahead

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?”
