Your DNA is constantly mutating, and that’s a good thing

Our bodily systems are rife with mutations. In fact, your DNA is mutating right now. These errors, and attempts to repair them, are a key to understanding immune function, aging, and even how heart disease develops. Gene mutations can even mitigate the harm caused by some inherited diseases. Host Ira Flatow goes on a journey through the illuminating science of genetic mutations with Roxanne Khamsi, science writer and author of “Beyond Inheritance: Our Ever-Mutating Cells and a New Understanding of Health.” Guest: Roxanne Khamsi is a science writer and author of the book, “Beyond Inheritance: Our Ever-Mutating Cells and a New Understanding of Health.” Other episodes you may enjoy: How One Gene Affects Alzheimer’s Risk 65 Genomes Expand Our Picture Of Human Genetics Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Maine nearly became the first state to ban data centers

Data centers make controversial neighbors: They’re loud, they use a lot of water, and can drive electricity prices up. Following public concern and organizing efforts, Maine nearly implemented an 18-month ban on data center construction, before a governor veto. Joining Flora to talk about real changes communities can advocate for in regards to data centers are Pete McGuire, climate reporter at Maine Public, and Lauren Keeler, director of ASU’s Just Energy Transition Center. Guests: Pete McGuire is climate reporter at Maine Public. Dr. Lauren Keeler is an associate professor and director of the Just Energy Transition Center at Arizona State University.

What urban design tells us about democracy

The way ancient societies like the Greeks, Maya, and Khmer Empire built their cities can tell us a lot about how a place was governed. Did rulers live in ornate palaces or alongside other residents? Are there large, open spaces for community gatherings? In a new study, archaeologists document how they use the design of ancient temples, plazas, and cities to understand how a society was governed. So what does ancient architecture reveal about democracy? And do the democratic design principles hold true today? Host Flora Lichtman chats with anthropologist Jake Holland-Lulewicz about ancient democracies, and with archaeologist Jeff Hou about how the role of public spaces in democracies has changed. Guests: Dr. Jacob Holland-Lulewicz is an anthropologist and assistant professor at Penn State. Dr. Jeff Hou is the head of the architecture department at the National University of Singapore.

The long history of birds, from velociraptors to pigeons

Comparing a backyard sparrow to a fearsome velociraptor seems odd, but modern birds are indeed living dinosaurs. Scientists are finding more and more connections between the past physiology of dinos and the present physiology of birds. Joining Ira Flatow to talk about some forgotten species from the past tens of millions of years—think gorilla-sized penguins—is Steve Brusatte, paleontologist and author of “The Story of Birds: A New History from their Dinosaur Origins to the Present.” Read an excerpt from “The Story of Birds” Guest: Dr. Steve Brusatte is a paleontologist and author of “The Story of Birds: A New History from their Dinosaur Origins to the Present.” He’s based in Edinburgh, Scotland.

The lucky breaks that make our Earth home

What makes Earth special, and why are we here at all? In his book “Why Do We Exist? The Nine Realms of the Universe That Make You Possible,” astrophysicist Hakeem Oluseyi tackles the conditions needed to put life on Earth, from the formation of stars, to self-organizing molecules, to quantum weirdness and the nature of time. He joins Host Flora Lichtman to celebrate our place in the cosmos. Read an excerpt from "Why Do We Exist?" Guest: Dr. Hakeem Oluseyi is an astrophysicist and author of “Why Do We Exist? The Nine Realms of the Universe that Make You Possible.” Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

Listening for the cosmic ‘dark ages,’ from the lunar far side

What did the universe look like before any stars turned on? Astronomers call that time the “dark ages,” and while they think it may be possible to see remnants of it in very low frequency radio signals, hearing those signals from Earth can be challenging. One possibility is to put a radio telescope on the far side of the moon, where it would have periods of observation shielded from interference both from Earth and from the sun—and potentially be able to receive that dark ages signal. The LuSEE-Night mission will explore that approach. A small demonstration radio telescope is slated for launch in late 2026 to serve as a proof of concept for low frequency radio astronomy on the lunar far side. Astronomer Anže Slosar, lead scientist for LuSEE-Night, joins Host Ira Flatow to describe the telescope project and what astronomers hope to achieve by sending it to the moon. Other episodes you may enjoy: CERN finds a new particle + News alerts for the cosmos 3D Images Of Galaxies Will Rock You (Ft. Queen) Guests: Dr. Anže Slosar is science lead for the LuSEE-Night project. He’s based at Brookhaven National Lab. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How do you describe nature? Two poets help us

To mark Earth Day, we asked you to tell us about your favorite places on the planet. You took us to the woods near Traverse City, Michigan, to a lake in Oklahoma, to Long Island Harbor where you spent your summers as a kid. Basking in a sea breeze and admiring a sunset are basic human pleasures. But how do you take these moments and turn them into meaning? How do you pin those feelings down with words? Joining Host Flora Lichtman are two poets who make that attempt for their livelihood: Jane Hirshfield, founder of Poets for Science, and Kimberly Blaeser, founding director of Indigenous Nations Poets and former Wisconsin poet laureate. Guests: Kimberly Blaeser is a poet, founding director of Indigenous Nations Poets, and former Wisconsin Poet Laureate. Jane Hirshfield is a poet, essayist, and translator. She is the author of “Ledger” (Knopf, 2020) and nine other books of poetry. She’s based in San Francisco, California. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

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.

How New Jersey tamped down PFAS in drinking water

Nearly all Americans have some type of PFAS, commonly known as “forever chemicals,” in their blood. The chemicals, which are linked to numerous health issues, were first regulated in drinking water at the federal level two years ago (though some limits have been rolled back). But, back in 2018, New Jersey became the first state to adopt its own drinking water standards for PFAS. Now, researchers at Rutgers University have crunched the data to see how well it worked. They found that levels of the regulated chemicals dropped by as much as 55%. Host Ira Flatow talks with the lead author of the study, cancer epidemiologist Hari Iyer about the significance of his findings and his plans to study the possible link between PFAS and prostate cancer. Want to filter PFAS from your tap at home? Learn more: Identifying Drinking Water Filters Certified to Reduce PFAS via EPA Home Water Treatment for PFAS via PennState Extension Guest: Dr. Hari Iyer is an assistant professor of cancer epidemiology and health outcomes at the Rutgers Cancer Institute of New Jersey.
