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.
