By one estimate the average American home has 300,000 objects. Yet our ancient ancestors had no more than what they could carry with them. How did we go from being self-sufficient primates to nonstop shoppers? We examine the evolutionary history of stuff through the lens of archeology beginning with he ancestor who first picked up a palm-sized rock and made it into a tool.

With planets and moons, it’s what’s inside that counts. If we want to understand surface features, like volcanoes, or their history, such as how the planet formed or whether it’s suitable for life, we study their interiors. Astronomer Sabine Stanley takes us on a journey to the centers of Venus, Saturn’s large moon Titan, Jupiter’s moon Io, and of course Earth, to help us understand how they, and the solar system, came to be.

Guest:

Sabine Stanley - Planetary scientist at Johns Hopkins University and the author of What’s Hidden Inside Planets.

Worried that AI will replace you? It may not seem like the Hollywood writers’ strike has anything in common with the Luddite rebellion in England in 1811, but they are surprisingly similar. Today we use the term “Luddite” dismissively to describe a technophobe, but the original Luddites – cloth workers – organized and fought Industrial Revolution automation and the factory bosses who were replacing humans with cotton spinning machines and steam powered looms. Find out what our age of AI can learn from textile workers of 200 years ago about keeping humans

in the loop.

Bigfoot could get official status if proposed legislation passes making it the state cryptid of California. If nothing else, the effort shows that fascination with cryptids has an outsized footprint on our culture. We look at why mythical creatures continue to capture imaginations - as well as passions - of die-hard believers, despite no evidence for their existence. An author uncovers the origin of a beloved hoax in the American West and its unexpected ties to a real animal and historical medical breakthrough. But are we looking for creature delights in all the wrong places? A tally of Earth’s species reveals that far more remain unidentified than are currently known. Newly discovered critters such as the Yeti crab and an organism dubbed the

Flying Spaghetti Monster are so strange, it challenges us to separate fauna fact from folktale.

Self-driving cars, once a thing of science fiction, have become a reality in a handful of cities across the country. As our vehicles gain autonomy, they may provoke a profound shift not unlike the introduction of the first car in the late1800s and raise the question of whether the human driver will soon be obsolete. For a glimpse into the future of self-driving cars, we take a spin through the history of the automobile, from the Model T to the driverless taxi-cab. Along the way, we explore the rise of American manufacturing and the unmistakable but unexpected way in which we have bonded to our four-wheeled companions.

Asteroids are rich in precious metals and other valuable resources. But mining them presents considerable challenges. We discuss these, and consider how these spinning, rocky resources might be the key to a space-faring future. But an economist points out the consequences of bringing material back to Earth, and a scientist raises an ethical question; do we have an obligation to keep the asteroids intact for science?

Guests:

Jim Bell - Planetary scientist in the School of Earth and Space Exploration at Arizona State University.

Martin Elvis - Astronomer and author of “Asteroids: How Love, Fear, and Greed Will Determine Our Future in Space.”

Ian Lange - Economist and associate professor at the Colorado School of Mines and author of a paper on the feasibility of asteroid mining.

Firing federal workers and freezing grants has upended research institutions, prompting uncertainty about their futures. We look at the real-world impacts these policy changes may have for our mechanisms for collecting and sharing important data. An NIH grant recipient considers the future of her lab’s ability to do basic research, including studying complex diseases such as Alzheimer’s and heart disease. An interruption in reliable access to CDC data comes as highly contagious avian influenza continues to evolve and spread in the U.S. And what does the gutting of NOAA imply for collecting essential weather data, including those used to forecast hurricanes?

Guests:

What’s it like to live on a block of ice, especially when it thaws? An environment writer shares his forty-year experience in the Arctic, including the time a paddling polar bear tracked him on a river. He describes the stunning beauty of America’s last truly wild place and the dramatic changes to the landscape he recently witnessed. Recent research has backed up his eyewitness accounts, as an arctic scientist presents the latest data collected from a part of world warming four times faster than the rest of the planet.

Two infectious diseases that we’ve been able to prevent for a half-century are re-emerging. One of the most contagious viruses in the world, measles, is spreading in the United States. Anti-vax sentiment has driven vaccination rates down leading to outbreaks in Texas and New Mexico. The U.S. has also seen an uptick in cases of tuberculosis which has reclaimed its position as the deadliest infection globally. The author John Green shares how his travels to Sierra Leone inspired his new book about TB. Through the story of a young patient, Henry, he highlights the health inequities that contribute to over a million and a half tuberculosis deaths annually despite the existence of a cure.

Guests:

Adam Ratner – Pediatric infectious disease doctor in New York City, and author of Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children's Health

John Green – Author of The Fault in Our Stars, The Anthropocene Reviewed, and Everything is Tuberculosis: The History and Persistence of our Deadliest Infection

By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.

Guest:

Walt Hickey - journalist, data scientist, and author of “You Are What You Watch: How

Movies and TV Affect Everything”
