  • How does James Webb telescope work? What will it see?

    13/01/2022 Duration: 14min

    The atoms in our bodies were forged deep within the bellies of red giant stars eons ago. And if we peer deep enough into the night sky, we can see stars just like them taking shape at the edge of the observable universe. The light from those stars is more than 13 billion years old and thanks to the expansion of the universe, it has stretched out into super-long infrared wavelengths—basically heat. To “see” that heat, you need a really big, and really complex telescope. In space.

  • Did we just discover warp drive?

    23/12/2021 Duration: 08min

    In Star Trek the crew of the USS Enterprise zips between the stars in mere days, traveling a distance that takes light itself months or even years to cover. To do it they use a fantastic sci-fi technology called warp drive. The antimatter-powered warp drive bends spacetime for the Enterprise, making the distance between stars much, much shorter for the ship. Without it Kirk and the crew would grow old and die before they reached the outer edges of our galaxy—where a lot of the show takes place. And here on earth hundreds of years would pass. It would be a pretty depressing show.

  • Where are all the aliens?

    01/05/2021 Duration: 43min

    In this off-the-cuff episode I talk about some solutions to the Fermi Paradox (where is everybody in the galaxy?), the intergalactic object ʻOumuamua, and some science fiction. Enjoy!

  • Can drugs give you superpowers?

    14/11/2020 Duration: 11min

    My current novel is about everyday people who get superpowers from amazing future technology that I totally made up. The tech simply doesn’t exist, and probably won’t in my lifetime—or ever. But I want superpowers NOW. Fortunately, there are a myriad of for-real superpower technologies out there. Sure, they’re rudimentary and rife with life-threatening side effects, but they exist. So keep reading if you want to be faster, stronger, better NOW. Most of us know what steroids and other performance-enhancing drugs do, so I’ll try to stick to little-known facts. Most of this comes from the Mayo Clinic, which has compiled a detailed list of all the drugs you can take to make you awesome at sports.

  • Is wood the building material of the future?

    28/06/2020 Duration: 04min

    A new treatment process could make wood stronger than steel. In 1940 the de Havilland aircraft company introduced the Mosquito—a combat aircraft made almost entirely out of wood. A few years later the famously fastidious Howard Huges built the Spruce Goose out of, well, spruce (and other woods). In the ‘60s the British automotive manufacturer Marcos built its GT car using mostly plywood. Tons of other manufacturers have made aircraft, boats, and cars using wood or wood composites. But why isn’t wood construction more mainstream? Cars are steel (or aluminum). Bikes are steel (or aluminum). Skyscrapers and warehouses have bones of cold, hard steel. The stuff is simply stronger and tougher than wood. Until now.  Materials scientist Liangbing Hu at the University of Maryland has invented a method of treating wood that makes it stronger than steel, and even some titanium alloys. If their methods are proven out, we could see more cars, planes, and even skyscrapers built out of wood. It could reduce our reliance o

  • Should You Wear a Mask?

    22/06/2020 Duration: 03min

    Yes, yes you should.

  • How do squids change their own DNA?

    14/06/2020 Duration: 09min

    When you edit DNA, it’s permanent. The cell you edit will be changed forever, or at least until it dies. But what if there was a less-permanent way to edit genes?  There is, actually. It’s called RNA editing and it happens quite a bit in our own cells. RNA is the go-between in protein synthesis. DNA codes to RNA, which then codes to specific proteins. Proteins are what we’re all about, so if you alter anything in that production chain, you can potentially change the entire organism. In nature, RNA editing happens in that stage between DNA and protein synthesis. Here’s how it works: Imagine protein synthesis: DNA unravels and pairs up with messenger RNA. That RNA breaks off and goes to assemble some protein. Before it can, some sneaky enzymes jump in and make some changes to the RNA. Thanks to those changes, the RNA makes a new protein—one that isn’t coded in the DNA.  Why would this happen? Multicellular organisms like you and me are super complicated. We require lots of different kinds of proteins to func

  • Can you fix depression with magnets (TMS)?

    30/05/2020 Duration: 12min

    The doctors in Star Trek have an assortment of devices that can heal your ailments in seconds with beams of light or energy. Transcranial Magnetic Stimulation (TMS) uses high-powered magnets to beam energy directly into your brain. Proponents say the magnetic fields—and the electric currents they induce—can treat depression.

  • How do drugs help depression?

    11/03/2020 Duration: 29min

    Prozac was a miracle cure for my depression—until it wasn't. In this episode I explore serotonin's role in depression and why people like me experience "Prozac poop-out syndrome." Featuring Dr. George Keepers, Professor of Psychiatry at the Oregon Health and Science University's School of Medicine.

  • How do hydrogen cars work?

    12/01/2020 Duration: 16min

    The 2002 General Motors Hy-Wire was a hydrogen fuel cell car built to represent the future of GM—and automobiles in general. I got to drive the thing way back in 2002 during a press event. The Hy-Wire represented decades of research by engineers, and turned out to be a pretty good prediction of the future.

  • Can we burn metal as fuel?

    27/11/2019 Duration: 23min

    Even if we stick solar panels on every roof in the world, we’d still need a way to store energy to use when it gets dark. And a way to use that energy later to do more than just power a lightbulb—to do things like power construction equipment or move a cargo ship across the Pacific. Metal powder may be a great way to do it.

  • What‘s a pandora moth?

    12/09/2019 Duration: 24min

    I caught the tail end of the Pandora moth outbreak on a recent visit to Bend, Oregon. I lived in Bend for almost five years without seeing a single Pandora moth. This summer I saw thousands littering the streets and parking lots, mostly dead or dying. When I asked friends about the moths, I got shrugs. Nobody really knew what they were or where they came from.  I was fascinated. Was this a foreign invader, a ravenous beast that would defoliate the state? Would its larvae overwhelm the town come spring?

  • Can we go completely solar? With John McCone

    20/07/2019 Duration: 01h11min

    In this podcast I talk to scientist and philosopher John McCone about his excellent article “Blueprint for a Solar Economy.” John outlines a way to transition from fossil fuels to solar power using some of our existing fossil fuel infrastructure and existing solar technology. He paints a pretty hopeful picture of a solar-powered society that produces almost no carbon emissions.  It’s a hopeful picture of the future, which is something we all really need right now—and I really need—especially after the last podcast on the pending global climate apocalypse.  We talk about a lot of really interesting things, including using existing gas pipelines in the solar-powered world, and jet engines that run on powdered iron. You can read John’s article on his website: Blueprint for a Solar Economy

  • Will climate change destroy humanity?

    15/06/2019 Duration: 35min

    For the first time in human history, the concentration of CO2 in the atmosphere is 415 ppm. But what does that mean? Are we doomed to suffocate under a blanket of carbon, slowly cooking to death as the planet melts away beneath us? It’s not quite that bad, but it does not bode well for humanity. Listen, and head over to NY Mag and read David Wallace Wells’ article The Uninhabitable Earth. It’s masterfully written and utterly terrifying.

  • Superhero Science: Monica Rambeau aka Spectrum

    13/05/2019 Duration: 30min

    Carol Danvers isn't the most powerful Captain Marvel. That honor may just go to Monica Rambeau, the second Captain Marvel. She can transform into and manipulate any form of energy in the electromagnetic spectrum.

  • What‘s an analog computer?

    24/04/2019 Duration: 16min

    Digital is the past—the future is analog. Crackling, hissing, buzzing, messy, full-spectrum analog. The arcane electronic contraptions put people on the moon and they could be the key to true AI, perfect biological simulations, and even room-temperature quantum computing. Featuring a 1960s Smith-Corona electric typewriter and Ahmad Jamal.

  • Superhero Science: Captain Marvel

    06/04/2019 Duration: 17min

    She can punch through interstellar dreadnaughts like they were tissue paper, fire photon blasts that vaporize steel, and propel herself across the galaxy. She’s the most powerful superhero in the Marvel Cinematic Universe (MCU), and the science behind her powers is nothing short of spectacular.

  • What is reality?

    28/03/2019 Duration: 17min

    Dreamworlds are notoriously fickle. They exist solely in our minds, and thus aren’t grounded in any objective reality. In a very real sense, the act of observing something in a dream DOES change it because the dream and observer are one in the same. But what if the universe behaves in the same way? What if our mercurial dreams are really trying to reveal the deep, unsettling truth of reality? Do our observations create reality itself? Episode art by Nemi Fadda.

  • Why is fusion power taking so long? With John McCone

    06/03/2019 Duration: 26min

    Holding a miniature sun in a magnetic bottle isn't easy. But that's how you make a fusion reactor. In this episode I chat with plasma physicist John McCone about the challenges of building a functional fusion reactor. We talk about plasma blowtorches, neutron bombardment, lumpy magnetic fields, and ways to make a nuclear bomb.  

  • What‘s the Deal with Dieselgate?

    17/02/2019 Duration: 23min

    In 2015, the world's second largest car maker got caught cheating on emissions tests. It was bad. Really, really bad. VW diesel cars were cranking out toxic levels of nitrous oxides—and not the happy laughing gas kind. The deadly kind. Here's how it all went down.
