Take a road trip with us this summer as we revisit one of America’s most iconic landscapes: the Grand Canyon. This episode originally aired in 2019 to commemorate the 100th anniversary of the Grand Canyon’s designation as a national park. In this episode, host Dan LeDuc explores the beauty and geological history of this natural wonder with Wayne Ranney, a geologist who has spent his career studying the canyon.

In this episode, acclaimed documentarian Ken Burns offers us a look into his dynamic creative process and shares what inspires him to create powerful, enduring narratives of iconic historical figures and periods.

Since this episode originally aired in 2020, Burns has captivated audiences with documentaries on Ernest Hemingway, Muhammad Ali, Benjamin Franklin, the U.S. and the Holocaust, and the American buffalo as well as Burns’ first non-American figure and topic: Leonardo da Vinci. This fall, he will release a new series on PBS about the American Revolution and how the nation’s founding turned the world upside down.

This summer, we’re taking another look at one of the peskiest and deadliest insects on the planet: the mosquito. Millions of people are infected each year by diseases transmitted through mosquito bites, such as dengue fever, yellow fever, and malaria. In this episode, which originally aired in 2019, mosquito expert Carolyn “Lindy” McBride, a 2015 Pew biomedical scholar, shares the science behind why you may be more susceptible than other people to their bites.
