Ep. 32: Decentralized Internet, a Trip into Space, and a Roiling Debate Among Science Writers by

This month: building a heat map with the help of citizen scientists, monitoring an Estonian forest, and the heartbreaking cost of fragmented care.

This month: the toll of human-caused wildfires, rescuing snakes to prevent human-animal conflict, and capturing the impacts of an ambient killer. Transcript and individual segments available at https://undark.org/article/podcast-30-wildfires-snakes-air-pollution Update: An earlier version of this podcast and transcript provided an incorrect description of PM2.5, a scientific and regulatory term referring to fine particulate matter that is 2.5 micrometers or smaller in diameter. Although particulate pollution larger than 2.5 micrometers is generally considered less hazardous, it is still a public health concern. There is also no meaningful lower threshold for particulate pollution below 2.5 micrometers that can be considered safe.

Join former NYT Science Times editor David Corcoran for a discussion with popular science writer and prolific book author Carl Zimmer about the history of heredity, and why you can’t boil down something as complex as intelligence to a couple of genes. Also, podcast host Kasha Patel talks with Undark’s Matters of Fact and Tracker columnist Michael Schulson about the safety of CBD, or cannabidiol, for dogs; and science journalist Anja Krieger takes listeners to the small German town of Schleswig, where a major leak has sparked a big debate.

David Corcoran talks with former EPA administrator Gina McCarthy about bridging the gap between science and the public. Also: an airplane ride-along with a group of tornado chasers from the NOAA, a closer look a carbon dioxide study with big implications, and game of Two Truths and Lie.

Our latest podcast looks at the resilience of bees; a study in memory transfer; and an attack on science.

A tiny fish is fast disappearing from the Sacramento-San Joaquin Delta. Many ecologists consider it a sign that both the local ecosystem and the nation’s approach to conservation are in crisis.

In this episode of the Undark podcast, we talk with reporter Charles Schmidt about his article on a misguided U.S. crackdown on lead poisoning. Also, Vanessa Schipani on media violence and Garrett Tiedemann on the personal toll of a genetic disorder.

Our latest Undark podcast looks at an ancient civilization, rediscovered but threatened; science and the media; and the world's strangest flower.
