The PUNCH mission (starts at 8:05) NASA’s new mission to study the Sun is called PUNCH (Polarimeter to Unify the Corona and Heliosphere). In this episode of How on Earth we talk with solar physicist Dr. Craig DeForest, the Principal Investigator of the PUNCH mission. Dr. DeForest is a Program Director at the Boulder office of Southwest Research Institute, and he explains how PUNCH will use polarimetry to study the outer part of the solar atmosphere, the million-degree hot corona, and how it interacts and evolves into the solar wind.

Despite all the advances in modern medical science, a diagnosis of Cancer often casts a pallor of hopelessness, for both the patient and the practitioner. For many types the prognosis is often poor; the cure is often worse than the disease; victory is usually called simply remission, temporary, perhaps fleeting. One might think the inability to find a cure indicates bafflement by our scientists and stagnation in our efforts. According to Professor Michael Kinch, there is in fact a frenzy of activity by scientists and doctors. And a recent spate of breakthroughs, developing treatments based on the inherent powers of our immune systems, represent not a refutation of all we have known before, but a continuation of efforts made by medical pioneers stretching back over a century. His latest book is titled The End of The Beginning: Cancer, Immunity and the Future of a Cure. Kinch was a professor at Purdue University, where he researched breast and prostate cancer. He then went on to found an oncology program at the biotechnology company MedImmune. He is now professor and vice-chancellor at Washington University in St. Louis. Here he shares with Chip Grandits stories from the front lines in the battle with cancer, both past and present. He speaks with what can best be described as a disciplined optimism.
With graduation season is upon us, today’s edition of How on Earth is our annual “Graduation Special”. Our guests in the studio today are scientists who have or will soon receive their Ph.D. in a STEM-related field. They talk about their thesis research, their grad school experiences, and what they have planned next.

In this week’s show, Beth interviews Joshua Goldstein. He and co-author Steffan Qvist wrote eloquently about how nuclear energy can replace fossil fuels – a vital necessity in a rapidly warming world. A new generation of nuclear plants reduces waste and completely eliminates CO2. In Sweden, France and Ontario, these plants have allowed these countries to eliminate their reliance on fossil fuels and significantly reduce their carbon footprints.
