With graduation season upon us, today’s edition of How on Earth is Part 1 of our annual “Graduation Special”. Our guests in the studio today are scientists and engineers who have or will soon receive their Masters or Ph.D. from the University of Colorado in a STEM-related field. They talk about their thesis research, their grad school experiences, and what they have planned next.
Gautam Kavuri – Physics
Topic: Wringing the Bell: Implementations of Cryptographic Protocols Based on Bell Non-locality

Topic: Shape Diameter Computation on Surface Meshes and A Review of Shape Regularization Methods in Level-Set Topology Optimization
Sweet in Tooth and Claw (start time: 0:59) Since the 1800s, science has been obsessed with the notion, stemming from Charles Darwin’s theory of evolution through natural selection, that only the “fittest” can survive and pass on their strong genes. As in, it’s a ruthless, violent world. And today, we humans find ourselves mired in a hyper-polarized society fixated on competition, disruption, and “If you win, I lose” thinking. A good time to take a look at a different way of living together–how a “kinder, gentler” approach also helps species evolve. In this week’s show, Susan Moran interviews journalist/author Kristin Ohlson, whose most recent book, Sweet in Tooth and Claw: Stories of Generosity and Cooperation in the Natural World, was recently released in paperback by Patagonia Works.

Alexander Kramida – NIST Atomic Spectroscopy Group – phote from NIST
Federal cutbacks have led the National Institute of Standards and Technology to shut down a long-running, highly prized information center used by scientists around the world, for projects ranging from searching for exoplanets, to making better microchips, to detecting atomic missiles. Atomic Spectroscopy Database Manager Alexander Kramida explains the purpose of the Atomic Spectroscopy Group, the impact of losing it, and what’s next, now that federal budget cuts mean NIST is shutting it down.
Poisoning the Well (starts 2:00) Boulder science writer Sharon Udasin discusses her new book, Poisoning the Well: How Forever Chemicals Contaminated America. The book chronicles how these chemicals have ended up in our soil , drinking water, our bloodstreams . . . including in Colorado. She also explains what we can do about these sometimes useful, but far too often, health-endangering chemicals.
Today is April Fools’ day, when jokes and pranks are played, sometimes among friends and family, sometimes on a more public scale. But why is there such a day for culturally-accepted foolishness? To delve into the origins and history of April Fools’ Day, we talk with Dr. Angus Kress Gillespie, folklorist and professor of American studies at Rutgers University.
NEPA rollbacks, environmental impacts (start time: 6:25) Amidst a flurry of moves by the Trump administration to roll back environmental regulations, last month a White House agency proposed a rule to rescind a landmark law meant to protect wildlife, their habitat, and human communities from unchecked development, and to ensure that the public has a say in projects ranging from oil and gas drilling to wind and solar farms. The rule, if it goes into effect, would mean that the White House Council on Environmental Quality would no longer enforce how the National Environmental Policy Act (NEPA) is carried out. As a result, many infrastructure projects would not be subject to environmental review. A public comment period regarding this proposed rule ends on Friday, March 27. (Click here to submit any comments.) How On Earth host Susan Moran interviews Jim McElfish, a senior advisor at the Environmental Law Institute, a nonpartisan, nonprofit center working to strengthening environmental protection by improving law and governance.

On this week’s show, Beth talks with Brianne Barker, Associate Professor of Biology and Director of Undergraduate Research at Drew University. Dr Barker studies innate immune responses – these are the initial, non-specific actions taken by the immune system – to fight off retroviruses such as HIV (the AIDS virus). We discuss the measles virus, how it gets into cells, travels through the body to cause its many symptoms, which can be long-lasting and even lethal, and its frightening ability to wipe out, or erase, much of the accumulated memory of the immune system to previous infections. For an even deeper dive into this dangerous virus, you can hear Dr Barker and other virologists go into greater detail here.

We speak with Environmental Scientist Alan Townsend about his new book, This Ordinary Stardust: A Scientist’s Path from Grief to Wonder. It chronicles what happened when his family received two unthinkable, catastrophic diagnoses: his 4-year-old daughter and his brilliant scientist wife developed unrelated, life-threatening forms of brain cancer. As he witnessed his young daughter fight during the courageous final months of her mother’s life, Townsend – a lifelong scientist – was indelibly altered.
