Humankind has the technology to go to space. Space architect Ariel Ekblaw says the bottleneck now is real estate: getting larger volumes of space stations in orbit. Her company is working on the equivalent of giant, magnetic space Legos—hexagons that could self-assemble in space into livable, workable structures. This episode, host Regina G. Barber talks to her about this space architecture and why she says that the goal isn’t to abandon Earth–but to off-world industries like agriculture and manufacturing in order to build a better Earth.

This year, quantum science and computing came up a lot. There have been broad claims that quantum science and engineering could one day help cure diseases, design new materials, optimize supply chains -- or help in other ways not yet fathomable. And, while the Trump administration has made strides to cut scientific funding, quantum research is one of two things they’ve pledged to continue investing in – along with artificial intelligence. Meanwhile, scientists have been hard at work, pushing the research to move quantum engineering from sci-fi to real-world usefulness. All of this got science correspondent Katia Riddle wondering: When will all of this effort actually pay off? She talked to a lot of scientists to figure it out -- and to figure out how much scientist really understand about quantum science. She brings everything she learned onto the show today.

President Trump has signed an executive order that would block states from enforcing laws they pass to regulate A.I., or artificial intelligence.The directive marks a big win for tech giants but will likely be challenged in the courts. Jacob Ward, founder of The Rip Current, joins Geoff Bennett to help break down the concerns and the arguments around all of this.

Smashing up guitars is a classic rock star activity, but how about drowning them? 7-year-old listener Cornelius has set CrowdScience a challenge: to find out what happens if you play a guitar underwater. Could this be the next avant-garde music sensation?

Host and amateur musician Caroline Steel tackles Cornelius’ question with the help of one increasingly soggy guitar. The UK’s National Physical Laboratory is our first port of call, with a guitar-sized water tank at the ready, and acoustic scientists Dr Freya Malcher and Ben Ford helping tackle our questions.

Since an acoustic guitar’s sound is amplified by its internal chamber, what happens as that chamber starts to fill with water? How about if the whole guitar - strings, body and all - is submerged? What difference does it make if our ears are listening above or below the water? And can special water-adapted microphones help us explore this unusual question, before our guitar disintegrates?

Our guitar then heads off on tour to Denmark, where the band Between Music have teased out questions just like these for their underwater music project, Aquasonic. We talk to violinist and Innovative Director Robert Karlsson, and singer Nanna Bech, who also plays a unique subaquatic instrument. With their help, we discover how to get the best out of a submerged guitar, and find out whether other instruments are better suited to the life aquatic. Presenter: Caroline Steel

Over the Christmas season, it is estimated that some 3.6 million families in Japan will tuck into KFC over Christmas (other fried chicken is available), which inspired the Unexpected Elements team to chew over all things chicken!

First up, we discover that chicken may never have become domesticated if it wasn’t for rice farming. We also ponder whether the chicken or the egg came first (are you Team Chicken or Team Egg)? Next, we find out that humans are surprisingly smart at translating chicken chatter.

We’re then joined down the line by Dr Jingmai O’Connor, associate curator of fossil reptiles at the Field Museum of Natural History, who reveals more about the links between dinosaurs and birds.

Plus, how Brazil became a poultry superpower, and what happens to chickens in tornadoes.

All that, plus many more Unexpected Elements.

Want to be a top notch candidate for hosting alien life? Then there's a few key requirements you should be aware of: Ideally, you're a large object like a moon or a planet; scientists suspect you also have an atmosphere and water; plus, you should orbit your star from a nice mid-range distance — in the "Goldilocks Zone" of habitability. Until recently, you would be competing against TRAPPIST-1 e. It's a planet outside of our solar system. TRAPPIST-1 e is also only 40 light years away, rocky and the same size as Earth, which prompted researchers to investigate whether it also has an atmosphere — and the potential for alien life. A team of researchers has been investigating TRAPPIST-1 e to learn more about its potential. Their answers, recently published in the Astrophysical Journal Letters, say a lot not just about this exoplanet, but about how scientists should refocus their hunt for alien life.

In the 1970’s TV show called Six Million Dollar Man, a test pilot is in a horrible accident. The show’s famous line goes, “We can rebuild him. We have the technology.” Now, in the 2025 book, Replaceable You, science writer Mary Roach explores how people have collectively lived up to the task of rebuilding human bodies when they fail, as well as all the ways we may not quite be there yet. In this episode Regina G. Barber and Mary Roach discuss three chapters of the book, get into everything from iron lungs to private parts and try to answer the question, “How replaceable are you?”

More than 100 million people in the U.S. have some allergy each year. That’s about every 1 in 3 adults. For many, the fix is a bandaid: over-the-counter allergy medications. But there’s another treatment that works to lessen these reactions rather than just manage people’s symptoms, allergy shots. The treatment has been around for over a century and is still popular today. Patients have to take the shots for a few years, and it’s the closest thing science has to a cure. Host Regina G. Barber speaks with Dr. Gina Dapul-Hidalgo about how this immunotherapy works and how certain guidelines to keep your child from developing common food allergies have changed.

Thirty years ago, park rangers reintroduced grey wolves into Yellowstone National Park. They wanted to restore the ecosystem and get the elk population, which had decimated the plant community, in check. And it worked – or so the popular narrative suggests. But is it really so simple? Today on the show, we explore how the Yellowstone ecosystem has changed since wolves returned and whether those changes can really be pinned solely on wolves. Plus, how the narrative of the Yellowstone wolf legacy could affect wolf reintroduction elsewhere. (encore)

For years, solar power at home was mostly limited to people who owned their rooftops and could afford the steep upfront costs. But now, a new generation of small, affordable systems — often called "plug-in" solar — are making clean energy more accessible. Already widespread in Germany, the movement is gaining momentum in the United States. Laura Klivans of PBS member station KQED reports.
