Fairy Science // Audubon’s Christmas Bird Count

We offer two features on this Christmas Eve How On Earth.

Fairies in 19th century science education (start time: 3:52): Victorian educators used the magical world to teach young children about science. That was before fairies fell out of favor in science, alas. How On Earth co-host Jim Pullen talks with Melanie Keene, director of Studies for History and Philosophy of Science at Homerton College in Cambridge, England, about the understanding of fairies in science education in the Victorian age.

Christmas Bird Count (start time: 12:51) It’s the time of year when humans are flying hither and yon to gather with family for Christmas. Others are heading somewhere south for vacation to escape the winter chill. Many birds are on the move as well, heading south to overwinter. Others are sticking around. These human and avian patterns are converging with the annual Audubon Society’s Christmas Bird Count. Steve Jones and William Schmoker of the Boulder County Audubon Society talk with co-host Susan Moran about how the Bird Count emerged more than 100 years ago and why it’s important.

Big Game, Warm World // Hour of Code

Big Game and Climate Change (start time 5:00) Last week, the National Resource Council released some serious warnings about climate change, saying its impacts could be abrupt and surprising. But as How on Earth contributor Brian Calvert reports, the National Wildlife Federation says big game is already getting hit. Species from mule deer to antelope to bear are all dealing with climate change in their own ways. Only elk are faring better, at least for now. All of that could mean serious changes for Colorado’s hunters and wildlife watchers, says, Dr. Doug Inkley, the senior wildlife biologist for the organization and the lead author of a recent report, “Nowhere to Hide: Big Game Wildlife in a Warming World.”

Hour of Code (start time 12:30) Coding is not just a magic trick where ones and zeros make Angry Birds. But it can be surprisingly simple to learn. You can do it in an hour. But you might want to use a game built by a team here at CU-Boulder. The tutorial is being offered as part of Computer Science Week. In the studio with How On Earth’s Joel Parker to explain the university’s so-called “Hour of Code” is Alex Repenning, a computer science professor at CU.

Engineering for Kids // Antarctica’s Ross Sea

On Tuesday, Nov. 26, How On Earth brings you two features:

Feature #1: (start time 5:53) STEM, as you may well know, stands for Science, Technology, Engineering and Mathematics. Many math and science topics are introduced throughout most years of primary education, but technology and engineering — not so much. We live in a world surrounded by things imagined and designed and built by engineers, from roads and buildings to computers and appliances and even food, drugs and clothing. So it’s important to understand engineering if we want to understand these life necessities. An educator tackling this issue is Dr. Christine Cunningham, vice president of research and educator resource development for a project called “Engineering is Elementary.” It was developed by the Museum of Science in Boston. Cunningham is featured in an article, written by former How On Earth contributor Breanna Draxler, called “E is for Engineering” in the December issue of Discover magazine. Cunningham talks with host Joel Parker about how teaching engineering to very young students can be done.

Feature #2: (start time 14:45) Arguably the healthiest marine ecosystem on Earth is the Ross Sea in Antarctica. It’s so pristine largely because it is protected by a 500-mile-wide shield of floating sea ice, and, well, it’s not exactly easy to get to. But in recent years the Ross Sea has come under threat, largely from New Zealand industrial fishing ships that are hunting as far south as they can for the Antarctic toothfish, which was rebranded as Chilean sea bass for U.S. and other consumers. John Weller is a nature photographer and conservationist living in Boulder. He has documented the beauty and fragility of the Ross Sea in his new book, The Last Ocean. Weller also co-founded a nonprofit, called The Last Ocean Project, that is dedicated to protecting the Ross Sea and other fragile marine ecosystems. Weller talks about the science and art of these environments with host Susan Moran. (You also can hear a previous interview with Weller on KGNU’s Morning Magazine.)

Antarctica Research // The Cancer Chronicles

We offer two features on the Tuesday, Oct. 22, show:

Feature 1 – Antarctica Research (start time 4:15): Diane McKnight, a professor of civil, environmental and architectural engineering at the University of Colorado Boulder, talks with How On Earth contributor Brian Calvert about scientific discoveries from Antarctica. During the temporary government shutdown the United States Antarctic Program, which facilitates government-funded scientific research in Antarctica, was unplugged. Several expeditions were cancelled. Her research on the McMurdo Dry Valleys on the continent will resume, but a future government shutdown would threaten scientific research on penguins, extreme microbes, climate change-induced sea ice melt and so many other subjects.

Feature 2 – The Cancer Chronicles (start time 12:22): In his new book, The Cancer Chronicles: Unlocking Medicine’s Deepest Mystery , science writer George Johnson takes readers on his very personal quest to understand cancer on a cellular level: how it begins with one “renegade cell” that divides, mutates, and becomes a tumor. In the process Johnson also digs deep into history – per-history, in fact — to learn that not only our ancient human ancestors had cancer, but even some dinosaurs suffered from them. And the author dissects many scientific studies that debunk myths about the role environmental toxins play in cancer. And he challenges false beliefs that cancer in modern times is on the rise. “Yet running beneath the surface is a core rate of cancer, the legacy of being multicellular creatures in an imperfect world,” he writes. Johnson speaks via phone to host Susan Moran about the mysteries and discoveries of cancer.

And as we mentioned in today’s headlines, if you want to see the large fragment of the Chelyabinsk meteor being recovered from Lake Chebarkul, you can see the video here.

Safer Rocket Fuel // Inland-Ocean Connection

The Tuesday, Sept. 17, show offers two features:
Feature #1 (start time TK): Once hadrazine, now green. Ball Aerospace’s Chris McLean, the Program Manager for the Green Propellent Fusion Mission, talks with co-host Jim Pullen about testing a much safer spacecraft fuel.

Feature #2 (start time TK): The 100-year flood ravaging Colorado has shown us painfully clearly the power of water. We’re seeing how surging rainfall and overflowing streams can destroy homes, roads, indeed whole communities in their path. But what’s less visible is how extreme weather events like this one in the nation’s interior affect oceans in powerful ways. Our watersheds east of the Continental Divide carry water, and tons of nutrients, into the Mississippi River Basin. Rainfall, storm water, and fertilizer runoff from croplands and backyard lawns contribute to the humongous Dead Zone in the Gulf of Mexico. To discuss our inland connection to oceans Dr. David Guggenheim, a marine scientist and founder of the nonprofit Ocean Doctor, talks with co-host Susan Moran. Vicki Goldstein, founder of Colorado Ocean Coalition, also discusses the inland ocean movement, including the second annual Making Waves event this coming weekend.

Wildfires & Water Reservoirs // Comet ISON

For the Sept. 3rd How On Earth show we offer two features:

Wildfires Threaten Water Supplies: (start time 5:45) The wildfire burning in and around Yosemite National Park is now the fourth-largest in California’s history. Covering nearly 350 square miles, the Rim Fire is threatening the Hetch Hetchy Reservoir, which supplies residents in the San Francisco Bay Area with most of their water and power. It’s a lot like the 2012 High Park Fire—which sent ash and debris into the water supply of Fort Collins. These fires offer lessons on the risks wildfires pose to reservoirs. Dr. Bruce McGurk, a former water manager for Hetch Hetchy and a water consultant, speaks with How On Earth contributor Brian Calvert about the risks and future prospects.

Comet ISON Cometh: (start time 12:50) Comets have fascinated humans for millenia. Aristotle argued comets were hot, dry exhalations gathered in the atmosphere and occasionally burst into flame. Some people thought that comets replenished Earth’s air. Still others believed they were a source of disease. Scientists today study comets because some are thought to be relatively pristine leftover debris from the formation of the solar system. And studying what comets are made of can provide us a glimpse back to the beginning of the solar system 4 billion years ago. Comet ISON, as scientists call it, is one that scientists predict will be relatively easy to view later this year. Dr. Carey Lisse, a senior research scientist at the Johns Hopkins Institute Applied Physics Laboratory in Maryland, speaks with co-host Joel Parker about comet ISON and its fascinating tails. For more information on ISON, go to NASA’s ISON toolkit, and this cool interactive model.

Kepler’s Prospects // Oncofertility

For the August 20 How On Earth show we offer two features:

Kepler Spacecraft’s Uncertain Future: (start time 5:48) Are we alone in the cosmos? Are there other planets out there, and could some of them support life? Or, is Earth somehow unique in its ability to support life? The Kepler mission was designed to start addressing that question by searching for planets around other stars. Since its launch in March 2009, the Kepler spacecraft has discovered many diverse candidate planets around other stars, but recently the spacecraft has run into some technical problems. Dr. Steve Howell from NASA’s Ames Research Center talks with co-host Joel Parker about Kepler’s past, present and future.

Cancer’s Impact on Fertility: (start time 14:52) It’s tough enough to receive a cancer diagnosis. For many patients, an added insult is that chemotherapy treatments can render them infertile. However, there are many options for cancer patients who want to have children, or more children – both men and women. A key problem has been that many of them aren’t educated by oncologists about their fertility options and they jump right into drug treatments. Dr. Laxmi Kondapalli, an assistant professor of reproductive endocrinology and infertility at the University of Colorado Denver and head of the CU Cancer Center’s Oncofertility Program, talks with co-host Susan Moran about the medical science of take cancer therapies and the latest in fertility-preservation options.

China’s environmental impact // 100 Year Starship

Today, June 18, we offer two features interviews:
Feature #1 – China’s Environmental Impact (start time 4:46): China’s meteoric economic rise is causing harmful side effects, ranging from choking air pollution domestically to threatened forests, wildlife and air quality around the globe. Of course China’s per capita greenhouse gas emissions still pale in comparison to those in the United States, and roughly one-third of China’s CO2 emissions are generated to manufacture goods that are exported to the U.S. and other nations. Craig Simons, a former journalist and author of a recently published book, The Devouring Dragon: How China’s Rise Threatens Our Natural World, discusses with co-host Susan Moran these critical issues, including coal mining in Colorado for export to China.

Feature #2 – 100 Year Starship (start time 15:35): Science and exploration tend to be long-term commitments. That’s well-known by fans of the “Hitchhiker’s Guide to The Galaxy” series, where the computer Deep Thought did calculations for 7.5 million years to find the answer to The Ultimate Question of Life, the Universe, and everything. However, projects on our world tend to be limited by shorter-term political and funding cycles. So it is hard enough to consider projects that require thinking a decade into the future, beyond many political lifetimes. What about projects that require thinking a century or more into the future, many generations from now? Well, that is exactly what one group of space exploration advocates is working toward. The project is called the 100 Year Starship, which aims to create a long-duration mission sending humans to another star. Alires Almon, member of the project, talks with co-host Joel Parker about the challenges and the vision of 100 Year Starship.

Feature #1 (start time 5:36): Cancer drugs are much more targeted than they were many years ago. But researchers are still trying to find a way to deliver drugs much more precisely to cancer cells, partly to avoid damaging, sometimes lethal, side effects. A huge obstacle has been getting nucleic acids to cross the membrane of cancer cells. A new study has brought researchers closer to crossing this big hurdle. Dr. Tom Anchordoquy, a lead author of the study, speaks with co-host Susan Moran about the study and what it means for cancer patients and researchers. Dr. Anchordoquy is an investigator at the University of Colorado Cancer Center in Denver and a professor at the Skaggs School of Pharmacy and Pharmaceutical Sciences.

Feature #2 (start time 15:02): Being an astronaut is a risky job, but perhaps one of the less-known risks is the high levels of radiation beyond the relatively protective cocoon of Earth’s magnetic field. This will be a particularly important problem to address for long-duration deep-space flight such as going to Mars. Until recently there have not been a lot of measurements available of the interplanetary radiation field for the types of radiation that could affect humans. But on the Curiosity rover of the Mars Science Laboratory, there is a radiation detector designed to make those important measurements. The instrument team recently published their initial results. Dr. Don Hassler, Science Program Director at Southwest Research Institute’s Boulder office and the Principal Investigator for the Radiation Assessment Detector on the Mars Curiosity rover, talks with co-host Joel Parker about the results.

Feature #1 (starts 05:25): A sweeping new report on the state of climate change and its current and future impacts in the United States was recently released in draft form. It’s called the National Climate Assessment. It comes at a time when major storms and wildfires are increasing in many areas. And last year the continental U.S. experienced its hottest year ever recorded. How On Earth co-host Susan Moran interviews one of the participating authors of the report, Dr. Dennis Ojima. He’s a professor at Colorado State University in the Ecosystem Science and Sustainability Department, and a senior research scientist in the Natural Resource Ecology Laboratory. Dr. Ojima co-wrote the chapter on the Great Plains.

Feature #2 (starts 16:30): Paul D. Miller, a.k.a. DJ Spooky, says the pallet of a 21st-century artist is data. That’s certainly the approach he took after visiting Antarctica in 2007—Miller used scientific data from ice cores and other Antarctic sources to create musical motifs representing the southern continent, then blended them with live performers and his own hip-hop beats. Co-host Ted Burnham speaks with Miller about the process of “remixing” the frozen Antarctic landscape, and about how music and art offer new ways to make scientific topics such as climate change accessible and meaningful.
