• "A Very, Very Big Deal." Countries Take On Fossil Fuels

  Many countries are frustrated with U.N. climate conferences. While some countries urgently want to transition away from fossil fuels — the main driver of global warming — others are blocking that language from climate agreements. Today on the show, Emily talks with Julia Simon from NPR’s climate desk. She takes us to Brazil and introduces us to a group of countries that are trying something new.Interested in more science and climate related news?

• Could Architecture In Space Make A Greener Earth?

  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.If you liked this episode, check out our Space Camp series.Interested in more space tech episodes?

• Is The Quantum Future Here?

  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. To hear more Short Wave reporting on quantum clocks, check out this episode: Quantum Mechanics For BeginnersInterested in more quantum science?

• Could This Exoplanet Harbor Life?

  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.Interested in more space science?

• How Replaceable Are You?

  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?”Interested in more science behind the human body?
