In 1991, hikers in the Alps spotted what looked like a doll frozen in the ice. It wasn’t a toy. It was a body. What police thought was a recent accident turns out to be something far stranger.

In this episode, Nate talks with author and journalist Brenda Fowler about the discovery of Ötzi the Iceman and the science that helped unravel his story. What can one frozen body teach us about early human civilization? Much more than you’d think.

Brenda is the author of Iceman Uncovering the Life and Times of a Prehistoric Man Found in an Alpine Glacier.

Seeds hold history. They carry the genetic blueprints of the past and the key to our future. But when disaster strikes, how far will scientists go to save them before they’re lost forever?

In this episode of The Show About Science, Nate traces the incredible journey of some of the world’s most valuable seeds - from the Middle East to the Arctic Circle to the wheat fields of Kansas. Along the way, he uncovers how a global network of scientists are racing against time to safeguard our food supply for generations to come.

Joining us on this journey are Mark Schapiro, author of Seeds of Resistance: The Fight to Save Our Food Supply, Luigi Guarino from the Crop Trust, Zakaria Kehel from the International Center for Agricultural Research in the Dry Areas (ICARDA), and Bart Panis from the World Banana Collection.

It's the hottest day of the year, and deep underground, a mysterious countdown has finally hit zero. After years of silence, millions of cicadas are emerging from the earth, ready to take the stage in a once-in-a-lifetime event. But how do these creatures synchronize their grand entrance?

In this episode of The Show About Science, Nate explores the fascinating world of cicadas emerging en masse after years of living underground. Joined by Jorin Graham, a physics PhD student from Northwestern University, they dive into the science behind cicada synchronization, the role of xylem in their lifecycle, and how synchronization mechanisms are key in nature.

Bacteriophages, also known as ‘phages,’ are the most common lifeform on the planet. They are constantly hunting for bacteria to infect and kill. What if we could harness these tiny microbes to help us in our fight against harmful, disease-causing bacteria? On this episode of The Show About Science, Ben Chan, from Yale University, joins Nate to explore the potential of phages in treating human infections amid the declining effectiveness of broad-spectrum antibiotics.

If you’re interested in collecting phage samples, you can email Ben at [email protected] for further instructions on how to safely prepare and send your samples.

In this episode of The Show About Science, Nate heads to the banks of the Chicago River to meet up with Melissa Pierce, PhD, the Technical Program Director at Current, a nonprofit water innovation hub. Together, they explore the complex world of urban water chemistry, focusing on the river's historical pollution problems and the measures taken to improve the water quality, in particular, an in-depth look at Current's H2Now program. In the second part of the episode, Nate travels to Washington, DC, to chat with Steve MacAvoy, PhD, a professor at American University. Steve's research has centered around studying the impact of urban infrastructure on river water chemistry and how the rising concentrations of specific chemicals are impacting our waterways.
