This is a Science Show

Many of us never got to experience it, but the air quality in LA in the ‘40s  ‘50s, ‘60s, and ‘70s was deadly. Smog hung in the air like a thick fog and many residents actually said that it hurt to breathe.

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....

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...

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!

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...

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 o...

Yes, yes you should.

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 a...

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.

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.

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.

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.

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...

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 pic...

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 ma...

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.

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.

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.

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 o...

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.  

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.

This summer a lot of science news bubbled up out of the quantum foam, but the one thing that really caught my attention was booze. And not Oregon’s world-famous craft beers. A study landed that allegedly found that any amount of alcohol—any—is bad for you. But that doesn't mean you shouldn't drink.

That’s the bone-chilling shriek of America’s favorite pest, the trash panda. Or Raccoon. And while they may sound like demons shredding the flesh from helpless babes, there’s something even more terrifying about them: Their poop.

Psychologist and author David P. Barash recently wrote an article for Nautilus Magazine arguing that now is the time to make a humanzee. I wrote a story about an experiment gone horribly wrong. How are they related? Listen to find out!https://dustindriver.com/simple-procedure.html http://nautil.us/issue/58/self/its-time-to-make-human_chimp-hybrids

No fancy sci-fi introduction is needed this time, folks, because today we have world-renown CRISPR expert Sam Sternberg. Sam worked with biochemist, author, and science celebrity Jennifer Doudna to refine CRISPR gene editing technology at UC Berkeley. The two wrote best-selling book A Crack in Creation about the discovery and what it could mean for humanity. Today Sam is working on CRISPR at Colum...
