Red Meat & Mice // Loren Cordain – The Paleo Diet

Filed under Episodes by Shelley Schlender on December 30, 2014 at 11:49 am {one comment}

Ajit Varki UC-San Diego

“Sugar” in Red Meat – Cancer in Mice? (starts at 6:10) We talk with Ajit Varki, a researcher at the University of California in San Diego whose latest mouse studies reveal a potential inflammatory compound in red meat — a “sugar” called sialic acid. (For more, listen to our extended version of this interview)

Loren Cordain Founder of the Paleo Diet movement

Paleo Diet – Avoid Grains and Beans (starts at 9:10) We talk with Colorado State University scientist Loren Cordain, founder of the Paleo Diet movement. He and his colleagues have study humans and the influence of diet. For health and athletic performance, Loren recommends avoiding modern foods that are high in grains, sugar, salt, legumes and additives. Instead, he says, eat like our paleo ancestors – fruits and vegetables and fats and meat. (For a fee, you can subscribe to Loren’s latest podcasts at his website. Fro free, you can listen to older podcasts. Find out more at thepaleodiet.com.

Today’s show also includes a look back at some of our favorite science stories from 2014.

Red Meat Sugar Glycans and Inflammation – Extended Version

Filed under Extras by Shelley Schlender on December 30, 2014 at 11:42 am {no comments}

I’m Shelley Schlender for How on Earth. Up next is an extended interview with University of California in San Diego scientist Ajit Varki about his team’s new mouse study that indicates that a “sugar” in red meat, called sialic acid, can trigger inflammation when fed to mice. This sugar is intriguing because it’s a molecule that two million years ago, our human bodies made on their own. It differs from the current sialic acid made in our bodies by just one atom of oxygen. Yet the mouse studies indicate that might be enough to cause an immune system reaction in the lab mice. More research and human studies will be needed, to determine whether or not a similar reaction occurs in susceptible humans. Now here’s Ajit Varki.

Solar Flares — High-Tech Armageddon?

Filed under Episodes by Shelley Schlender on September 2, 2014 at 11:10 am {no comments}

Coronal Mass Ejection (Solar Flare) courtesy NASA

Recent headlines warn that Coronal Mass Ejections, better known as Solar Flares, could trigger a high-tech Armageddon, disabling power and communication on a global scale, for months. Today we talk with Boulder scientists Dan Baker, Laboratory for Atmospheric and Space Physics, and Doug Biesecker, National Space Weather Prediction Center, about the risks from Solar Flares, what to worry about, and what is being done to protect us.

In today’s science show, we also feature upcoming talks on Science.
* This Wednesday at 7 PM, How on Earth’s Joel Parker will talk about Chasing Comets: The Rosetta Mission, at the Denver Science Museum.
* This Friday at 7:30, Conservative Christian and Prominent Atmospheric Scientist, Katharine Hayhoe, will talk about, “Climate Change with Mind & Heart,” at Boulder’s Chautauqua Auditorium.

Rosetta // Autism & the Microbiome

Filed under Episodes, Our Microbes, Ourselves by Shelley Schlender on July 29, 2014 at 8:35 am {no comments}

Caltech Scientist Sarkis Mazmanian

We talk with Joel Parker about his Denver Science Museum presentation. Joel is a project leader for one of the scientific instruments on board the Rosetta space mission. We also discuss new findings about how improving the health of the human digestive tract, with the use of beneficial microbes, might improve mood disorders, including reducing the anxiety that’s common with autism.

Wireless Technology – Extended Version of Interview with Frank Barnes and Katie Singer

Filed under Extras by Shelley Schlender on June 3, 2014 at 8:48 am {one comment}

CU-Boulder Electrical Engineering Emeritus Professor Frank Barnes is the past president of the BioElectroMagnetics Society. He recently chaired a National Research Council panel on research priorities related to the potential health effects of exposure to radio frequency energy from the use of wireless technology, such as cell phones. As a scientist, Frank Barnes recently talked with a citizen activist, Katie Singer, about her new book, An Electronic Silent Spring. This is an extended version of the interview we broadcast on June 3rd 2014. — Shelley Schlender

How Native Americans Came to Be – Extended Version – Beringia

Filed under Extras by Shelley Schlender on March 3, 2014 at 8:09 pm {no comments}

Alaska Shrub/Willow Tundra

I’m Shelley Schlender for How on Earth. Here’s an extended version of an interview about how Native Americans came to be. It’s about a CU-Boulder study that appeared in Science Magazine in February 2014, and promptly made headlines around the world. The study involves top-notch detective work that shows how, almost 30,000 years ago, a major Ice Age trapped Asian explorers on a land bridge between Asia and Alaska for 10 THOUSAND years. Back then, the “Beringia” (bare-IN-gee-ah) land bridge was 30 miles long and 600 miles wide. Glaciers had buried Northern America, but Beringia was just warm enough, the trapped explorers survived and thrived. They stayed in that pit stop for so many thousands of years, it gave time for the inevitable mutations that can happen in DNA to be concentrated and become distributed throughout the entire Beringian community, which probably included a few thousand people. When the glaciers finally receded around 15,000 years ago, that DNA signature was with the small band of “Beringians” who then began settling in the Americas. Their settlements were successful. Their numbers grew over time to become the millions of people today who still carry “Beringia” in their DNA. Today, we call that distinct, Beringian DNA proof that someone’s ancestors were “Native Americans.”

Hospital Acquired Infections (8:00) When Americans go to the hospital, they don’t expect to leave with a brand new illness. But one out of every 20 receives a hidden time bomb during these visits — it’s a healthcare associated infection. How on Earth’s Shelley Schlender visits Longmont United Hospital to see how ICU staff reduce infection risks. If you want to compare how your hospital or clinic compares with the nation, and other Colorado hospitals, when it comes to infections, here are Colorado’s Latest Infection Rate Reports
