Magnetic Braking in Old Stars (starts at 3:13) Dr. Travis Metcalfe from the White Dwarf Research Corporation talks about studies of one particular star, 51 Peg, that has gone through magnetic braking. He discussed how studying magnetic fields around similarly middle-aged and older stars not oly can help us in our search for life on other planets, but also provide a clue of what might have impacted the evolution of life here on Earth.
Citizen Science with Zooniverse (starts at 13:21) Dr. Laura Trouille from the Adler Planetarium is the Principal Investigator of the Zooniverse project. She explains how “citizen science” works, which crowd-sources science research in a wide range of projects not only in astronomy, but topics ranging from biology and physics to arts and literature.

Today’s show features the following interviews, by How On Earth’s Susan Moran and guest host Ted Wood.
Audubon’s Climate Watch (start time: 4:03) Starting on Jan. 14, the Audubon Society will launch a month-long citizen science program to better understand how birds are responding to climate change. This comes at a time when, according to a 2019 Audubon report, up to two-thirds of North American birds are vulnerable to extinction due to climate change. But the Climate Watch program is one of many opportunities to protect birds. Alison Holloran, executive director of Audubon Rockies, discusses the program and how you can get involved.
Conservation on the Edges (start time: 13:26) Charismatic predators like polar bears, grizzlies, and tigers, get lots of attention, and for good reason. But many lesser known species, particularly those living in extreme environments–including muskoxen, wild yaks, takins and saigas–are also important species. They have been the research focus of Joel Berger, a professor of wildlife conservation at Colorado State University. He’s also senior scientist at Wildlife Conservation Society. Berger’s latest book is Extreme Conservation: Life at the Edges of the World.

Attention all Nature Lovers and Amateur Naturalists, Friday April 27th kicks of the City Nature Challenge, where Boulder will compete with 65 cities throughout the world to identify the most species within their area over a 4 day period. It’s a competition to identify biodiversity powered by the enthusiasm of citizen scientists. Chip Grandits speaks with Dave Sutherland and Melanie Hill two members of the Wild Boulder Team, which is organizing the City Nature Challenge for Boulder.
Citizen science is enhanced with iNaturalist a crowd sourcing platform developed by the California Academy of Sciences with applications for you smartphone which can help you can tap into a global network of amateurs and experts to help identify what species that thing is which you can never quite identify.

The Long Now Foundation in Colorado (start time 5:02): People often measure “success” as fifteen minutes of fame, or a blockbuster financial quarter. This focus on short term results doesn’t always build the skills needed to solve long-term problems, such as reducing disease outbreaks or maintaining species diversity. So some visionaries have created a playfully serious way to think ahead, and those “ways” include projects here in Colorado. Shelley Schlender tells us about the Long Now Foundation who are developing programs to foster long term responsibility and long term thinking.
Wild Boulder (start time 10:t28): Boulder is launching a new citizen science project. The project, called Wild Boulder, will allow people in Boulder to use their smartphones to record wildlife observations, including photos, and share this information with local land managers and open space experts. To find out how this program works, and how it will benefit the community, we spoke with Dave Sutherland and Melanie Hill. Dave Sutherland is an Interpretive Naturalist with theCity of Boulder’s Open Space and Mountain Parksprogram. Melanie Hill is Director of Communications for the WILD Foundation, which works to protect wilderness while balancing the needs of human communities.
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 someinexpensivetools, 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.

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.

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.

Astronomy Through the Ages (starts at 4:10): If I ask you to close your eyes and imagine an astronomer, what do you see? Maybe you think of a lone figure hunched all night over the eyepiece of a telescope in a big, domed observatory. Maybe you think of Jodie Foster, as Ellie Arroway in the movie Contact, wearing headphones to listen in on cosmic radio waves at Arecibo.
My mind always wanders back to a woodcut of Tycho Brahe’s 16th-century observatory, filled with intricate equipment for making naked-eye observations of the night sky.
But do any of these ingenious images actually resemble the life of an astronomer today? And how are new technologies and “big data” changing the way we study stars today and in years to come?
To discuss those questions, we’re joined in our Boulder studio by Dr. John Bally, a professor of astronomy at the University of Colorado, and Dr. Seth Hornstein, director of the Sommers-Bausch Observatory on the CU campus.

Buzz Aldrin’s Vision for Space Exploration (starts at 6:14) Dr. Buzz Aldrin advocates that the United States should not enter a space-race to the moon against the Chinese, or a race to Mars against the Russians, but rather show leadership by cooperating with the major space-faring nations to systematically step across the great void to the Red Planet. This is his personal Unified Space Vision. He is also working toward an independent council, a United Strategic Space Enterprise, that would advise American citizens about the nation’s space policy. USSE experts would draw on a deep knowledge of America’s previous successes and failures to present a unified plan of exploration, science, development, commerce, and security within a national foreign policy context. Buzz shared these visions with How On Earth’s Jim Pullen. Here’s an excerpt from his hour-long discussion with Jim. Stay tuned for the rest of his discussion, in which he shares little-known insights into why Apollo 11, not Apollo 12, was first to land humans on the moon, and never-before-shared honors for Neil Armstrong and Pete Conrad.
The Bees Needs (starts at 16:04) Colorado is home to over nine-hundred species of wild bees. Most of these solitary creatures nest in the ground, but others nest in the hollow stalks of plants, and about one hundred and fifty species nest in holes in wood. How are these bees doing? Are pesticides striking them down, like their honeybee cousins? How will they respond to changes in climate? CU scientists Dr. Alex Rose and Dr. Virginia Scott have embarked on a journey of discovery, and they’ve invited ordinary people to help. It’s the Bees Needs, a citizen-science project. How On Earther Jim Pullen is a part of that citizen-science team, and he invited Virgina and Alex to see what’s happening at the bustling bee block nest outside our studio.

Feature #1: Many problems plague the oceans and the fish and other species that inhabit them: overfishing, pollution, and much more. But perhaps the greatest threat to sea life – and possibly to humans – is ocean acidification. That’s when the chemistry of the ocean changes and causes seawater to become more acidic because the ocean is absorbing carbon dioxide from the atmosphere. This increase in ocean acidity makes it difficult for many plants and animals in the ocean to make or maintain their shells or skeletons. The head of the National Oceanic and Atmospheric Administration (NOAA), Jane Lubchenco, recently said that the ocean is becoming more acidic at rates not seen for at least 20 million years, and that’s due mostly to increases in CO2 in the atmosphere. The threat is so grave that NOAA recently created a distinct Ocean Acidification Program. In May, Dr. Libby Jewett was appointed the first director of the program. We talk with Dr. Jewett find out more about the problem and what she aims to do about it.
Feature #2: Some sciences have a tradition of fruitful interactions between professional researchers and amateurs, and this has been made even more accessible with data being able to be shared over the internet across the world. Dr. Pamela Gay, an Astronomer at Southern Illinois University, Edwardsville, is the architect and participant in many such collaborations. In addition to her teaching and research, she does extensive public outreach to share the excitement of astronomy (such as her podcast AstronomyCast.com) and even finds ways to let anyone with an internet connection make new scientific discoveries and find new worlds that will be visited by spacecraft (IceHunters.org). We talk with Dr. Gay about the Zooniverse and her hunt for of icy objects in the outer solar system.
