The Middle + SciFri: How Can Trust In Science Be Restored?

We’re bringing you a special bonus episode from our friends at the live call-in show “The Middle with Jeremy Hobson.” Jeremy is joined by Science Friday Host Flora Lichtman and theoretical astrophysicist Priya Natarajan to talk about how trust in science can be restored. It took a hit with the COVID-19 pandemic, and the Trump Administration has now elevated science skeptics to positions of power and proposed giant cuts in scientific research.

Tracking The Toxic Fallout Of The LA Fires

This time last year, Los Angeles was on fire, and more than 16,000 homes and buildings burned to the ground. Cars, batteries, solar panels, insulation, and cleaning supplies went up in flames, releasing chemicals like lead, benzene, and asbestos into giant smoke plumes that wafted across the city. A year later, scientists are trying to understand the fallout of this urban wildfire—what chemicals got left behind, how to remediate them, and the threats to our health. Host Flora Lichtman talks with Yifang Zhu and Francois Tissot, who are at the forefront of this research. And for one of them, this work is personal. Guests: Dr. François Tissot is a professor of geochemistry at Caltech in Pasadena, California. Dr. Yifang Zhu is a professor of environmental health sciences at the University of California, Los Angeles. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Deepfakes Are Everywhere. What Can We Do?

Deepfakes have been everywhere lately, from fake AI images of Venezuelan leader Nicolás Maduro following his (real) capture by the United States, to X’s Grok AI generating nonconsensual images of real people in states of undress. And if you missed all that, you've almost certainly had your own deepfake close encounter in your feed: maybe rabbits bouncing on a trampoline or an unlikely animal friendship that seems a little too good to be true. Deepfakes have moved beyond the realm of novelty, and it’s more difficult than ever to know what is actually real online. So how did we get here and what is there, if anything, to do about it? Joining Host Flora Lichtman are Hany Farid, who’s studied digital forensics and how we relate to AI for over 25 years, and Sam Cole, a journalist at 404 Media who’s covered deepfakes and their impact since 2017. Guests: Dr. Hany Farid is a professor of electrical engineering and computer sciences at University of California, Berkeley. Sam Cole is a journalist at 404 Media, based in New York, NY Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

States Expected To See More ‘Anti-Science’ Bills This Year

An Associated Press investigation found that more than 420 “anti-science” bills were introduced in statehouses last year, targeting protections around public health issues like vaccines, milk safety, and fluoride. As state legislatures come back into session, what can we expect for 2026? Joining Ira Flatow is Laura Ungar, science and medical reporter for the Associated Press. Plus, reporter Elise Plunk joins Host Flora Lichtman to discuss the complex case of a citizen-led pollution monitoring program in Louisiana that persists despite a law banning the use of its data. Guests: Laura Ungar is a science and medical reporter for the Associated Press. Elise Plunk is an environmental reporter and Report for America corps member at the Louisiana Illuminator.

Why Astronomers Are Excited About Comet 3I/ATLAS’ Close Approach

This year, comet 3I/Atlas broke into our solar system, but also the zeitgeist. This dirty snowball is a visitor from another solar system, and it’s only the third interstellar object we’ve ever spotted. And today, it's closer to us than ever before—just 170 million miles away. Astronomy experts Stefanie Milam and Hakeem Oluseyi join Host Flora Lichtman to dish about 3I/ATLAS and how it captured the spotlight in a way that maybe no other big hunk of rock ever has. Plus, the sun is setting on the ISS, and the plan is to eventually crash it into the ocean. But wouldn’t it be cooler to send it into deep space instead? A listener pleads his case. Guests: Dr. Stefanie Milam is an astrochemist at NASA and a project scientist for the James Webb Space Telescope. She studies comets and interstellar objects. Dr. Hakeem Oluseyi is an astrophysicist and CEO of the Astronomical Society of the Pacific. Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

The Human Obsession With Aliens Goes Way, Way Back

A video shown on Capitol Hill on September 9 reportedly shows an American hellfire missile attacking and simply bouncing off a UAP (the military term for a UFO). When videos like this come out, speculation about aliens often follows. But our obsession with aliens isn’t new—and it didn’t begin with 1950s alien invasion movies like “The Day The Earth Stood Still,” or even with Orson Welles’ “War of the Worlds” mock news bulletins of the 1930s. As science reporter Becky Ferreira writes in her upcoming book, First Contact: The Story Of Our Obsession With Aliens, humans have been fascinated with the potential for alien life for about as long we’ve been around. She joins Host Ira Flatow to discuss how our views of beings from other worlds changed throughout the millennia, and where we’re at now with scientific exploration of life beyond Earth. Plus, science journalist Umair Irfan joins Ira to share other stories from the week in science, including what’s going on in a decision-making brain, the trouble with vector-borne illnesses, and the unusual tale of an ant queen that breeds ants of another species. Read an excerpt of First Contact: The Story Of Our Obsession With Aliens. Guests: Becky Ferreira is a science reporter at 404 Media and author of First Contact: The Story Of Our Obsession With Aliens. Umair Irfan is a senior correspondent at Vox, based in Washington, D.C.

What’s Happening On The Slippery Surface Of Ice?

It’s a wintertime question that you may have had as you struggled down a frozen sidewalk, or strapped on some ice skates: Just why is ice slippery, anyway? It turns out the answer is somewhat complicated. Mechanical engineer Robert Carpick studies tribology, the science of surface interactions, from friction to wear to lubrication. He joins Host Ira Flatow to wrangle some new ideas about the slippery science of ice. Guest: Dr. Robert Carpick is the John Henry Towne Professor in the department of mechanical engineering and applied mechanics at the University of Pennsylvania in Philadelphia.

Even Nobel Prize Winners Deal With Imposter Syndrome

Around 25 years ago, Ardem Patapoutian set out to investigate the fundamental biology behind our sense of touch. Through a long process of gene elimination, he identified a class of sensors in the cell membrane that turn physical pressure into an electrical signal. He changed the game in the field of sensation and perception, and in 2021 shared the Nobel Prize in Physiology or Medicine for his work. He joins Host Flora Lichtman to talk about his research, the odd jobs he worked along the way, and how he found a sense of belonging in science. Guest: Dr. Ardem Patapoutian is a professor and the Presidential Endowed Chair in Neurobiology at the Scripps Research Institute in La Jolla, California.

Secrets Of Ancient Concrete, And... Data Centers In Space?

The concrete of ancient Rome is famous for its durability. Just look at the Pantheon and those iconic aqueducts that helped transport water throughout the empire—still standing 2,000 years later. But knowledge about how this concrete was made hasn’t been very solid. Well, scientists have discovered a construction site in Pompeii preserved in the volcanic ash, which might hold clues to how we can improve our concrete today. Concrete researcher Admir Masic joins Host Ira Flatow to discuss the findings. Plus, we’ll look at the infrastructure of the future with engineer Benjamin Lee, who breaks down the recent news of tech companies looking to move their power-hungry data centers to space. They discuss the daunting engineering challenges and possible benefits. Guests: Dr. Admir Masic is an associate professor of civil and environmental engineering at MIT in Cambridge, Massachusetts. Dr. Benjamin Lee is a professor in the department of electrical and systems engineering and the department of computer and information science at the University of Pennsylvania in Philadelphia.
