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.

What Greenland Sharks Are Teaching Us About Aging Eyes

As we age, our vision gets blurrier, we form cataracts, and we have a higher risk of glaucoma. But Greenland sharks live for hundreds of years and still maintain healthy, functional eyeballs. So what gives? Host Ira Flatow talks with molecular biologist Dorota Skowronska-Krawczyk, who studies the mechanisms of aging, about what we can learn from these fishy eyeballs and how it could help us. Plus, listener Leon called us with a question: Is it true that the James Webb Space Telescope’s gold-plated mirror is so perfectly flat that if it were the size of the United States, the highest bump would be the size of a baseball? Not quite. Host Flora Lichtman discusses this feat of engineering with JWST project scientist Macarena Garcia Marin. Guests: Dr. Dorota Skowronska-Krawczyk is a molecular biologist and associate professor at the University of California, Irvine. She studies the mechanisms of aging. Dr. Macarena Garcia Marin is a project scientist for the James Webb Space Telescope at the Space Telescope and Science Institute in Baltimore, Maryland.

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.

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.

Drilling Into The Details Of Venezuela’s Oil

With President Trump’s moves to take control of Venezuela’s oil production—including the seizure of incoming and outgoing oil tankers—there’s been a lot of talk about the country’s deep reserves of crude. But not all oil is the same, and getting the Venezuelan reserves out of the ground might be neither cheap nor simple. So who wants that oil, and what is it good for? Petroleum engineer Jennifer Miskimins joins Host Ira Flatow to drill into the ABCs of oil production and refining. Guest: Dr. Jennifer Miskimins is 2026 president of the Society of Petroleum Engineers, and head of the petroleum engineering department at the Colorado School of Mines in Golden, Colorado.
