Teens4Oceans (starts at 9:15): Today, we’re kicking off a series of interviews on the show called The Ocean Is Us. We’ll explore how all of us living in land-locked Colorado are connected to the ocean — whether it’s through our watershed that flows into the Gulf of Mexico, or the fish we buy at the grocery store, or the carbon dioxide we emit that acidifies the oceans. Teens4Oceans is a nonprofit organization based in Colorado that is inspiring teenagers nationwide to become passionate ocean lovers and scientists through experiential learning — doing real marine research in the field.

How On Earth’s Susan Moran interviews Mikki McComb-Kobza, a marine biologist and executive director of Teens4Oceans, and Shelby Austin, who recently graduated from Ralston Valley High School in Arvada. For more information on our inland connection to the ocean and you can get involved, visit Colorado Ocean Coalition. And check out KGNUs year-long series, called Connecting the Drops, on Colorado water issues, at kgnu.org and yourwatercolorado.org.

Caffeine and Athletics

Caffeine and Athletics (starts at 4:35): Chances are you’ve already had a cup of coffee this morning or, if you are like me, it was a cup of tea. Or maybe, if you are truly hedonistic, you started the day with a bar of chocolate. Either way, if any of these options are part of your daily routine you’d be one of the 90 percent of people in this country that regularly consumes caffeine, America’s drug of choice.

In this week’s show we talk to Murray Carpenter, author of the book Caffeinated: How Our Daily Habit Helps, Hurts and Hooks Us. Although he covers the history and culture of caffeine in his book, he is specifically going to be talking about the science of caffeine and how this powerful drug affects our cognition and physical health. In particular, for all you runners, cyclists and swimmers out there – there maybe a few of you in Boulder – he’s going to discuss how the right dose of caffeine can help an athlete’s performance. Apparently, for you runners who can run a 40-minute 10K without caffeine, ingesting the drug can help knock 72 seconds off your time. That would put you at least 100 places higher in the Bolder Boulder.

Hope On Earth

Hope On Earth (starts 7:08): Few people have thought as critically and deeply about the state of Earth and our role on it than Paul Ehrlich. Over the course of several decades, the Stanford University biologist and ecologist has written many books, including 1968’s controversial The Population Bomb, in which he predicted that hundreds of millions of people would starve to death in the 1970s due to overpopulation and limited resources.

He has just come out with a new book, which he co-wrote with Michael Charles Tobias, an ecologist, filmmaker, book author and animal rights advocate. The book is called Hope On Earth: A Conversation. And indeed, it is a conversation between Ehrlich and Tobias. In fact, their conversation –many of them — took place here in a research outpost just outside of Crested Butte.

Both men join us by phone to discuss the book and the most pressing environmental issues of the day that it explores.

Massive Stars

Massive stars (start time 6:45) Dr. Emily Levesque is an astronomer who studies big stars, distant stars, exploding stars, and truly weird stars called Thorne–Żytkow objects. All of these topics relate to massive stars – stars that are more than eight time more massive than our Sun. Dr. Levesque is a postdoctoral Hubble fellowship and Einstein fellowship researcher at the University of Colorado at Boulder. She received a physics degree from MIT, and a PhD in astronomy from the University of Hawaii, which resulted in the Astronomical Society of the Pacific awarding her the Robert J. Trumpler award for outstanding PhD thesis, and this year she was awarded the Annie Jump Cannon award by the American Astronomical Society for her work studying gamma-ray bursts. Dr. Levesque, is here in the studio with us today to talk about her favorite weird astrophysical phenomena and the life of an observational astronomer.

As the end of the school year approaches for high school students, it’s a good time to celebrate the achievements and passion of students in Colorado who have excelled in science, technology, math and engineering (STEM). Two of them — Hope Weinstein, a senior at Fairview High in Boulder, and Michael Brady, a senior at Cherry Creek High School in Greenwood Village — were finalists at a renowned global competition last week. It’s the Intel International Science and Engineering Fair, which is a program of Society for Science & the Public.
Hope and Michael talk with co-host Susan Moran about their research and their message to other students.

Rosetta Comet Mission (starts at 15:16)

When he’s not busy volunteering with How On Earth, Joel Parker is an astronomer with the Southwest Research Institute — and that’s the hat he has on today as our in-studio guest. He joins us to talk about the European Space Agency’s Rosetta mission, which will tag along with comet 67P/Churyumov-Gerasimenko as it swings nearer to the sun later this summer.

Joel is the Deputy Lead Investigator for ALICE, the ultraviolet spectrometer aboard the spacecraft. He’s also the featured presenter at Cafe Scientifique tomorrow night. So think of this conversation as a preview of what you might hear if you join him tomorrow at Brooklyn’s down in Denver. Joel will give a very informal talk starting at 6:30 pm, and will try to answer all your tough questions about comets, Rosetta, or anything else. CafeSci is free and open to the public.

Gold Lab // National Climate Assessment

For our May 13th show we offer two features:
Gold Lab Symposium (starts at 3:42): Biotech entrepreneur Larry Gold, a CU Boulder professor at the BioFrontiers Institute, talks with How On Earth’s Shelley Schlender about the annual Gold Lab Symposium, which will be held in Boulder May 16th and 17th. This year’s theme is Embracing the Reptile Within: Head, Heart and Healthcare. The event will focus on research and educational approaches that can potentially help improve the U.S. healthcare system.

U.S. Climate Change Report (starts at 11:50) The National Climate Assessment, a sobering new report on the science and impacts of climate change in the U.S., makes it starkly clear that human-induced climate change is already affecting all parts of the country. It is making water more scarce in some regions while bringing torrential rains elsewhere. It is making heat waves more common and severe, and it’s causing more severe and destructive wildfires. How On Earth co-host Susan Moran talks with two guests: Kristen Averyt, PhD, is a lead author of a chapter on Energy, Water and Land. She is associate director for Science at the Cooperative Institute for Research in Environmental Sciences (CIRES) at CU Boulder. Dan Glick is a journalist who helped edit the report. His company, The Story Group, also produced a series of videos that highlight the report’s key findings and how climate change is affecting many people’s lives and livelihoods.

Hacking Happiness

You drive to Starbucks with your cell phone in your pocket, go online, read your favorite newspaper, share an interesting book review on Facebook and then go and order the bestseller from Amazon. It’s only 9:00am, but you’ve already left a data trail—a big one—on your whereabouts, your taste, your friends, and your financial habits.

In his new book, Hacking Happiness: Why Your Personal Data Counts and How Tracking It Can Change the World, John C. Havens talks about how megacorporations hoard these details and use them for their own monetary gain. But, Havens argues it doesn’t have to be like that. Using emerging technologies, we can reclaim control over our information and use it, not to boost company sales, but to improve our own happiness.

Baseball Vision // Emerald Ash Borer

Today, April 29th, we offer two features:
Baseball Vision (starts at 5:42): The major league baseball season is now in full “swing.” Fans may take it for granted that these professional athletes are in top physical condition. What’s less known is how important it is for baseball players to have perfect eyesight. Batters in particular have some of the best vision in the world. To find out how scientists know this, and study it, and even make it better, How on Earth’s Shelley Schlender last month headed down to spring training in Arizona. There, she caught up with two of the nation’s top experts on the science of vision, and sports.

Emerald Ash Borer (starts at 11:21): It’s been called the most destructive looming pest blight to hit Colorado in ages. The perpetrator in question is the emerald ash borer, a small shimmery green beetle. It is believed to have hitchhiked to the U.S. and Canada on cargo ships, or airplanes, from its native Asia, in 2002. Since then it has wiped out millions of ash trees in many states. Last September, the ash borer was first found in Colorado. Ash trees have had no time to develop resistance against the exotic invader. And meanwhile, the ash borer has no predators here to keep it in check. Dr. Whitney Cranshaw, an entomologist at Colorado State University, talks with host Susan Moran about what we should know about the emerald ash borer.

NASA Visit // IPCC Report

Earth Day gives us plenty of reason to reflect on the state of the planet and the impact we humans have had on it. This week’s show featured Dr. Linda Mearns, a senior scientist at the National Center for Atmospheric Research in Boulder, who is among hundreds of scientists who produced the latest report on global climate change. She’s a lead author of a chapter on regional climate change in the Fifth Assessment Report (AR5) of the United Nation’s Intergovernmental Panel on Climate Change. She also co-authored previous IPCC assessments – in 1995, 2001, and 2007. Dr. Mearns talks with How On Earth host Susan Moran about the science and implications of the IPCC report, including what it means for Colorado and the broader U.S. West.

Unfortunately, due to a technical glitch at the station, the recording of that live interview was lost. But we still have audio from our second feature.

Charles Bolden, the top administrator at NASA, was here in Boulder last week, touring the classrooms and facilities that earn the University of Colorado more space agency dollars than any other public university in the nation. We’ll hear what he has to say about CU’s role in the space program — past, present and future.

We’ve also recreated the Earth Day tribute that opened the show. These days it’s more like Earth Week, and it’s not too late to catch some of the planet-happy celebrations going on in the Boulder area this weekend. Listen for details.
