Kgnu - How On Earth

Tom's River (starts at 5:03) Susan Moran interviews Dan Fagin, author of the new book Toms River: A Story of Science and Salvation.  You’ve likely heard of the chemical contamination of Love Canal at Niagara Falls, in the mid-1970s. And the leukemia cluster linked to water pollution in Woburn, Massachusetts,in the mid-80s -- made famous by the book Civil Action. But you may not have heard of another cancer cluster –- also linked to industrial chemicals – this one in the small town of Toms River, N.J. Fagin's book about Tom's River is far more than a gripping investigation of one town’s struggle; it is a cautionary and illuminating tale about the complexities of finding a causal, not just associative, link between pollution and cancer. And it is a story for anyone concerned about whether the air they breathe, and the water they drink is in jeopardy.   2013-03-26 Making Fire on KGNU's How on Earth Science Show from Shelley Schlender on Vimeo.

Facing the Wave (starts at 04:50) Yesterday marked the two-year anniversary of the devastating earthquake and tsunami that rocked and partially devoured the northeastern coast of Japan. Although prone to earthquakes, the Tōhoku event hit a magnitude of 9.0, tying it for fourth largest earthquake on record according to the United States Geological Survey—a magnitude greater than scientists thought possible for this region. Last month, co-host Beth Bartel spoke with author Gretel Ehrlich about her recently published book “Facing the Wave: A Journey in the Wake of the Tsunami.” When asked about her motivation to write this book, Ehrlich, a long-time traveler to Japan, said simply that she went to see the effects of the wave because she had to. (Go to our extended interview for more about how the disaster spurred activism in Japan.) Pandora's Lunchbox (starts at 14:38) Did you ever think how long that energy bar you ate while skiing recently would last in tact beyond the expiration date? Or that bag of Oreo coo

This is an extended version of the interview we broadcast on March 12, 2013, featuring author Gretel Ehrlich discussing the aftermath of the March 11, 2011 Tōhoku earthquake and tsunami in Japan.

(Start time 5:15) “The Men of Earth came to Mars. They came because they were afraid or unafraid, because they were happy or unhappy, because they felt like Pilgrims or did not feel like Pilgrims. There was a reason for each man. They were leaving bad wives or bad towns; they were coming to find something or leave something or get something, to dig up something or bury something or leave something alone. They were coming with small dreams or large dreams or none at all...it was not unusual that the first men were few. The numbers grew steadily in proportion to the census of Earth Men already on Mars. There was comfort in numbers. But the first Lonely Ones had to stand by themselves...” That's from Ray Bradbury's great 1950 collection of short stories, The Martian Chronicles. Today, there are plans being made to send people to Mars, a fraughtful trip of a hundred and a half million kilometers and more than a year, each way. To learn whether we will be the Martians, we chat with Brian Enke. Brian is a Senior

The concept of a parallel universe, a universe remarkably like our own but with some subtle difference, has been the staple of science fiction stories for years.  But it is an idea that is seriously discussed in real science starting many decades ago when physicists wrestled with the weird implications of Quantum Mechanics, and recently has appeared in many other guises in other areas of physics. One of the leading scientists in studying these ideas and explaining the mind-bending concepts to non-experts is Professor Brian Greene.  Dr. Greene is professor of physics and mathematics at Columbia University and co-founder and director of the Institute for Strings, Cosmology and Astroparticle Physics.  He has written the books The Elegant Universe and The Fabric of the Cosmos, both of which were adapted into mini-series on NOVA, and his most recent book is The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos.  We talk with him about the different concepts in modern day physics that point to the

This is an extended version of the interview we broadcast on February 26, 2013, featuring Professor Brian Greene discussing the concepts of Parallel Universes.

Russian Meteor (starts at 4:28) Just a few days ago on February 15th,  a large meteor broke up in the skies over Russia, creating an air blast and sonic boom, which caused damage to buildings that injured over 1,000 people. We talk with Dr. Clark Chapman to ask why the universe is taking potshots at us.  Dr. Chapman is an astronomer and Senior Scientist at the Boulder office of the Southwest Research Institute, and is recognized as a leading researcher in planetary cratering and in the physical properties asteroids, comets, and moons.  For more than a decade Dr. Chapman has been studying the risks of comets and asteroids hitting the Earth and has been a member of Congressional and international committees regarding impact hazards. He is a founding member of the B612 Foundation, which is developing ways to detect and deflect hazardous asteroids. Dark Matter (starts at 12:45) Maybe you’ve heard about it.  Maybe you even know that it is everywhere throughout the universe.  But for such a ubiquitous material, wh

  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

Today on How On Earth, KGNU's award-winning science show, we sit down with Boulder's Dr. David Wineland and chat about his Nobel-prize-winning research. The NIST scientist shared the 2012 physics award with Frenchman Serge Haroche. They've developed experimental methods for trapping and holding particles so that weird quantum behaviors can be studied. The research is critical to developing extreme quantum computers that may someday break today's best encryption algorithms...and make truly unbreakable ones.

Feature #1: (start time: 06:03) On January 12, 2010, just over three years ago, a magnitude 7 earthquake shook Haiti, taking more than 200,000 lives and displacing an estimated 2 million. Still today, the International Organization for Migration estimates hundreds of thousands of people are without permanent homes, and in many ways Haiti seems no closer to rebuilding than it did three years ago.  Co-host Beth Bartel speaks to Haiti's first seismologists -- Roby Douilly and Steeve Symithe, both graduate students at Purdue University -- about the future of Haiti and a career in seismology there Feature #2: (start time: 15:42) You’ve probably heard by now that 2012 was the warmest ever in the U.S.  We’re not the only ones overheating. At the bottom of the world, over the last 50 years, West Antarctica has warmed more than scientists had thought. The implications are huge; an enormous ice sheet there  may be at risk of long-term collapse, which could cause sea levels to rise alarmingly.  Co-host Susan Moran spea

Feature #1: (start time 5:09)  Did you know that Colorado, and for that matter most states, have their own “state climatologist” – an expert who keeps tabs on the changing climate and its impacts in the state. In Colorado's case it's Nolan Doesken. He’s based out of the Colorado Climate Center at Colorado State University. Mr. Doesken also heads a nationwide citizen-science project called the  Community Collaborative Rain, Hail and Snow Network. How On Earth co-host Susan Moran interviews Mr. Doesken about the network, as well as a recently released Colorado River Basin Water Supply & Demand Study, which suggests we'll be thirstier and thirstier in the future. Feature #2: (start time 16:00) Water is such an essential -- perhaps the essential -- resource for life that it is considered as a key ingredient for life anywhere in the universe. No surprise, then, that it has become a battleground, especially in the Western states like Colorado that are dealing with drought conditions and higher demand for clean
