How a particle accelerator illuminated 56 human organs

A new imaging technique using a particle accelerator is giving researchers an unprecedented level of detail of our organs, producing scans 100 billion times brighter than a CT scanner. Those 3D models are now part of a public database called the Human Organ Atlas, available to researchers and the medically curious. Joining Host Ira Flatow to explain why they needed so much power and what kind of research advances will follow is imaging scientist Claire Walsh, director of the Human Organ Atlas hub. Check out images from the Human Organ Atlas on our website. Guest: Dr. Claire Walsh is an associate professor at the UCL department of mechanical engineering and director of the Human Organ Atlas Hub.

Why so many studies can’t be replicated

How do we know what we know? That's where science comes in—it gives us a method for testing our ideas and getting trustworthy results. But some researchers have warned that many scientific studies can't be replicated. To find out how deep the problem goes, the US Defense Advanced Research Projects Agency funded one of the largest analyses of social science, called the SCORE project. They checked the results of thousands of papers across economics, education, and psychology—and found that only half of them could be replicated. Joining Host Ira Flatow to discuss the findings are Tim Errington, one of the leads on this project, and economist Abel Brodeur, who recently released the results of a separate replication study that found more encouraging results than SCORE did. Guest: Dr. Tim Errington is senior director of research at the Center For Open Science in Washington, D.C. Dr. Abel Brodeur is a professor of economics at the University of Ottawa and founder of the Institute for Replication. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How a sound designer gave an alien its voice (and 250 words)

Movies may be a largely visual medium, but sound plays a huge role in setting tone, creating new worlds, and fleshing out characters. Sound designer Erik Aadahl has brought some of Hollywood’s iconic creatures to life with sound, like the Transformers, 2014’s Godzilla, and Rocky the alien from “Project Hail Mary.” He joins Flora to talk about the science of sound design, and how he uses his background in biology to look for sounds in the animal kingdom. Guest: Erik Aadahl is a sound designer and editor at E² in Los Angeles, California. Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

Artemis II test flight heads toward the moon

On Wednesday, NASA’s Artemis II mission launched, kicking off on a roughly 10-day trip that will carry four astronauts around the moon and back to Earth. The flight is another test of the Space Launch System rocket and the Orion capsule that are intended to be used for an eventual crewed lunar landing. Space reporter Brendan Byrne joins Producer Kathleen Davis to share his impressions of the launch and what’s ahead for the Artemis program. Then, moon book author Rebecca Boyle joins the discussion to tackle an important listener question: What if Earth didn’t have a moon? Guests: Brendan Byrne is the host of the “Are We There Yet?” podcast, and assistant news director for Central Florida Public Media in Orlando, Florida. Rebecca Boyle is a science journalist and author of “Our Moon: How Earth's Celestial Companion Transformed The Planet, Guided Evolution, And Made Us Who We Are.” Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Move over, vibe-coding. Vibe-proving is here for math

When ChatGPT first came onto the scene, it wowed users with its writing abilities, but drew laughs for generating images of seven-fingered hands and struggling with basic math, where 2+2 didn’t always equal 4. But more recently, things have changed: Google and OpenAI’s models bagged gold medals at the International Mathematical Olympiad last year, and now some experts say AI could pose an existential threat to the field of mathematics itself. Mathematicians Emily Riehl and Daniel Litt join Host Flora Lichtman to explore how this technology could change the way math discoveries are made—and what could be lost if things go too far. Guests: Dr. Emily Riehl is a professor of mathematics at Johns Hopkins University in Baltimore, MD. Dr. Daniel Litt is an associate professor of mathematics at the University of Toronto.

What a sperm whale’s birth tells us about whale culture

Scientists recently published the first footage of a sperm whale birth, and it was a crowded ordeal. More than 10 other sperm whales were there for the delivery and helped keep the baby whale afloat—and not all of them were related to mom. How much do we actually understand whale culture? And how should we think about altruism in the animal kingdom? Host Flora Lichtman chats with whale biologist Shane Gero about what it was like to witness this birth and what it tells us about whale culture. Guest: Dr. Shane Gero is a whale biologist at Carleton University, founder of The Dominica Sperm Whale Project, and biology lead for Project CETI. He’s based in Ottawa, Canada.

Can algae help pull microplastics out of our water supply?

Microplastics and nanoplastics have been found just about everywhere: in our soil, our bodies, and our water. Recent research involving bioengineered algae has had success in capturing and removing microplastics from water. Environmental reporter Kate Grumke joins Producer Kathleen Davis to talk about the latest approaches to addressing microplastics, and researcher Susie Dai discusses her work using algae to pull them out of wastewater. Guests: Dr. Susie Dai is a professor of chemical and environmental engineering at the University of Missouri. Kate Grumke is a senior environmental reporter for St. Louis Public Radio.

CERN finds a new particle + News alerts for the cosmos

Researchers at the Large Hadron Collider in Switzerland have announced that they discovered a new subatomic particle. Roughly four times more massive than a standard proton, this short-lived piece of matter called Ξcc⁺(Xi-cc-plus) is like an extra-heavy proton, researchers say. Physicist Hassan Jawahery joins Host Flora Lichtman to unpack how the particle was found, and what its discovery means for theoretical physics. Then, astronomer Eric Bellm describes a new alert system that could flag potentially significant changes in the southern night sky in real time. On its first night of testing at the Rubin Observatory in Chile, the system fired off 800,000 alerts. Guests: Dr. Hassan Jawahery is a distinguished university professor at the University of Maryland and a member of the LHCb consortium. Dr. Eric Bellm is alert product group lead for the Rubin Observatory and a research associate professor at the University of Washington.

Is Punch the monkey really just like us?

When Punch the monkey was abandoned by his mother, zookeepers gave him a surrogate and unexpected source of comfort: a stuffed animal. Videos of Punch snuggling the stuffie went viral, and, as his stardom rose, millions of us began wondering, “Is Punch OK? Does he have a girlfriend? Is he being bullied by the zoo's other macaques?” Primatologist Christine Webb joins Host Flora Lichtman to talk about the ways humans relate to our closest relatives, and whether we can—and should—map human feelings onto other primates. Guest: Christine Webb is an assistant professor of environmental studies at New York University. She is the author of “The Arrogant Ape: The Myth of Human Exceptionalism and Why It Matters.” Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The heaviness and (not) hope of climate change

For decades, renowned environmental writer Elizabeth Kolbert has taken readers to remote corners of the planet to understand how all life is connected—and how our planet is changing. She’s covered everything from the collapse of insect populations to the success of one town’s effort to go carbon neutral. Host Flora Lichtman speaks with Kolbert about the undeniable heaviness of our current climate moment, how the splendor of the Great Barrier Reef “tilted” her worldview, and the messy business of trying to solve environmental problems. In March and April, the Science Friday Book Club is reading Kolbert’s latest book, “Life on a Little-Known Planet.” It’s a collection of essays she’s written over the years. Check out the Book Club to read along. Guest: Elizabeth Kolbert is a staff writer at The New Yorker and the author of several books, including “Life on a Little-Known Planet: Dispatches from a Changing World.” Transcripts for each episode are available within 1-3 days at sciencefriday.com.
