Scientists recently discovered bats, like Tuvan throat singers and death-metal vocalists, produce sound using ventricular folds instead of vocal cords. A Danish biologist found bats use these for low-frequency calls. With their ability to also make extremely high-pitched calls, bats possess an unparalleled vocal range. The Center for Biological Diversity argues this makes them more akin to grindcore vocalists, who utilize both very low and very high frequencies.

The Center for Biological Diversity, a 501c3 nonprofit, works to secure a future for all species through science, law, and creative media. Check out our video to hear biodiversity-loving grindcore artists and see brutally cute bats. Learn more at biologicaldiversity.org or email us at center@biologicaldiversity.org.

"Two American Families: 1991-2024" is a "knockout documentary" (The New York Times) chronicling the economic struggles of two Milwaukee families—one Black, one white—over three decades. From 1991 to 2024, the Stanleys and Neumanns have battled poverty amidst a changing U.S. economy, marked by global shifts and lower-wage work, raising unsettling questions about America's economic future.

With profound intimacy, this FRONTLINE film reveals how these families and their now-grown children have navigated six presidential administrations, facing continuous challenges. As Terry Neumann notes, "It's like we haven't come very far," yet Jackie Stanley declares, "I won't give up." Directed by Tom Casciato and Kathleen Hughes, it offers a powerful window into enduring hardship.

Tim Wu, the scholar who coined "net neutrality," examines how big tech platforms have reshaped our economy. In his latest book, *The Age of Extraction*, Wu argues that the internet, once seen as a source of widespread wealth and democracy, has instead created new economic classes and fostered autocracy. He proposes solutions to harness technology for the greater good and build a more balanced economy.

Join Tim Wu, author of *The Age of Extraction*, and journalist Laura Sydell on November 10, 2025, to discuss reclaiming economic control. This program is supported by the Ken & Jaclyn Broad Family Fund and partnered with the Center for Humane Technology.
