We rely on the Global Positioning System for so much — mapping our commutes, tracking our runs, hailing ride shares, matching with dates and more — that it can be hard to remember life before it. The U.S. military sent the first GPS satellite to space in 1978, and journalist Katherine Dunn says remembering those military roots can help us understand of how enemy actors today are distorting, blocking and threatening GPS around the world. Dunn says it’s time we address our global dependency and rethink how we’ve phased out many GPS alternatives. We’ll talk with Dunn about how GPS works, the types of attacks we’re seeing and what can be done about them. Do you remember a time before GPS? Guests: Katherine Dunn, author, “Little Blue Dot: How GPS Shaped the Modern World"; journalist who specializes in covering the intersection between climate change, the energy transition, and business Learn more about your ad choices.

Communities across the Bay Area, including Gilroy, Oakley and Pittsburg, are pushing back on new data centers in their cities. Data centers, which house the computing equipment and servers that power the internet, have been around for decades, but opposition to them has exploded as tech companies pour hundreds of billions of dollars into building thousands of new centers nationwide. Residents worry the facilities will suck up scarce water and electricity and pollute the environment to power the riches of AI investors. We’ll talk about the data center boom and how it’s playing out in the Bay Area. Guests: Molly Taft, senior climate reporter, WIRED Jonathan Koomey, researcher and scientist, Koomey Analytics; author, "Cold Cash, Cool Climate: Science-Based Advice for Ecological Entrepreneurs" Hema Sivanandam, East Contra Costa reporter, Bay Area News Group Britt Smith, Gilroy resident; activist and co-founder, Stop Gilroy Data Center Learn more about your ad choices.

Historian Ibram X. Kendi says that in order to understand the rise of authoritarianism, we need to understand great replacement theory. It’s the racist idea that “powerful elites are enabling peoples of color to steal the lives, livelihoods, cultures and electoral power and freedoms of white people,” Kendi writes in his new book, “Chain of Ideas: The Origins of Our Authoritarian Age.” We talk to the National Book Award-winning author about how politicians are using great replacement theory to justify authoritarian power and how it has moved from the fringes to the mainstream. Guests: Ibram X. Kendi, professor of history, Howard University and founding director of the Howard University Institute for Advanced Study; author, "Chain of Ideas: The Origins of Our Authoritarian Age"; his previous books include "How to Be an Antiracist" and "Stamped from the Beginning: The Definitive History of Racist Ideas in America."

New Yorker magazine poetry editor Kevin Young has called poetry "the most efficient mode of time travel." In his new volume of poems "Night Watch,” Young, a literary hyphenate who edits, writes and teaches, takes readers on a journey of loss and re-emergence. From his cycle of poems about a conjoined pair of twins born into slavery and kidnapped to a carnival freak show to his meditations on grief set to the phases of the moon, Young’s spare and incisive language provides the reader passage through history and memory. On this Juneteenth holiday we listen back on our conversation with Young about his collection and what it means to be a poet today. Guests: Kevin Young, poet and author; Young's latest poetry collection is "Night Watch"; Young has been the poetry editor for the New Yorker since 2017 and from 2021 to 2025 served as the director of the Smithsonian's National Museum of African American History and Culture Learn more about your ad choices.

We tend to focus on how climate change affects coral reefs, sea turtles and polar bears on melting ice. But we rarely focus on how climate change is affecting microbes — the bacteria, fungi and viruses we can only see with microscopes — which outnumber all other life on earth. So says science writer Shayla Love, who warns that a warming planet might be making those microorganisms mutate in a concerning and even deadly way. And that melting ice may even unleash new, unfamiliar microbes. We talk with Love about her New Yorker article, “Our Warming Planet Is a Petri Dish for New and Deadly Microbes.” Guests: Shayla Love, science writer; her recent New Yorker article is “Our Warming Planet Is a Petri Dish for New and Deadly Microbes” Learn more about your ad choices.

Cigarettes are cool again…especially with GenZ. Despite decades of anti-smoking campaigns, you’re likely to see more young people smoking in films, at bars, on street corners, and in social media feeds. Researchers tie the trend to Y2K nostalgia, soft nihilism, and a turn away from “clean girl” wellness culture. Actual youth smoking rates are still at historic lows, but we’ll explore how glamorization complicates the public health conversation around nicotine. Guests: Pamela Ling, professor of medicine, UCSF; Ling studies the tobacco industry marketing strategies targeting young adults, women and other high risk populations Kevin Truong, business editor, The San Francisco Standard; Truong co-wrote the piece "They Know It Kills You. Gen Z is Smoking Cigarettes Anyway" Degen Pener, journalist; Pener wrote the piece "Cigarettes Get a Sequel: Hollywood's 'Cool' Habit Is Back" Learn more about your ad choices.
