It was the most famous invasion that never happened. But Orson Welles’ 1938 “War of the Worlds” broadcast sure sounded convincing as it used news bulletins and eyewitness accounts to describe an existential Martian attack. The public panicked. Or did it? New research says that claims of mass hysteria were overblown.
On the 75th anniversary of the broadcast: How the media manufactured descriptions of a fearful public and why – with our continued fondness for conspiracies – we could be hoodwinked again.
Plus, journalism ethics in the age of social media. Can we tweet “Mars is attacking!” with impunity?
And why we’re obsessed with the Red Planet.

Your brain is made up of cells. Each one does its own, cell thing. But remarkable behavior emerges when lots of them join up in the grey matter club. You are a conscious being – a single neuron isn’t.
Find out about the counter-intuitive process known as emergence – when simple stuff develops complex forms and complex behavior – and all without a blueprint.
Plus self-organization in the natural world, and how Darwinian evolution can be speeded up.
Discovering bacteria on Mars would be big news. But nothing would scratch our alien itch like making contact with intelligent life. Hear why one man is impatient for the discovery, and also about the new tools that may speed up the “eureka” moment. One novel telescope may help us find E.T. at home, by detecting the heat of his cities.
Also, the father of modern SETI research and how decoding the squeals of dolphins could teach us how to communicate with aliens.
Let there be light! Well, it’s easy to do: just flip a switch. But it took more than the invention of the light bulb to make that possible. It required new technology for the distribution of electricity. And that came, not so much from Thomas Edison, but from a Serbian genius named Nikola Tesla.
Hear his story plus ideas on what might be the breakthrough energy innovations of the future. Perhaps hydrogen-fueled cars, nuclear fusion electrical generators or even orbiting solar cells?
Plus, a reminder of cutting-edge technology back in Napoleon’s day: lighthouses.
You can’t see it, but it’s there, whether an atom, a gravity wave, or the bottom of the ocean … but we have technology that allows us to detect what eludes our sight. When we do, whole worlds open up.
Without telescopes, asteroids become visible only three seconds before they slam into the Earth. Find out how we track them long before that happens. Also, could pulsars help us detect the gravity waves that Einstein’s theory predicts?
Plus, why string theory and parallel universes may remain just interesting ideas … the story of the woman who mapped the ocean floor … and why the disappearance of honeybees may change what you eat.
Imagine: Your pint-sized pup is descended from a line of predatory wolves. We have purposefully bred a new species – dogs – to live in harmony with us. But interactions between species, known as co-evolution, happen all the time, even without deliberate intervention. And it’s frequently a boon to survival: Without the symbiotic relationship we have with bugs in our gut, one that’s evolved with time, we wouldn’t exist.
Discover the Bogart-and-Bacall-like relationships between bacteria and humans, and what we learn by seeing genes mutate in the lab, real time. Also, the dog-eat-dog debate about when canines were first domesticated, and how agriculture, hip-hop music, and technology can alter our DNA (eventually).
Plus, why some of the fastest humans in history have hailed from one small area of a small Caribbean island. Is there a gene for that?
ENCORE The Day After. 2001. Prometheus. There are sci-fi films a’plenty … but how much science is in the fiction? We take the fact checkers to Hollywood to investigate the science behind everything from space travel to human cloning.
Plus, guess what sci-fi film is the most scientifically accurate (hint: we’ve already mentioned it). Also, why messing with medical facts on film can be dangerous … and the inside scoop from a writer of one of television’s most successful sci-fi franchises.
And, a robot who surpasses even Tinseltown’s lively imagination: a humanoid that may become a surrogate you.
First released July 30, 2012.
ENCORE Let there be light. Otherwise we couldn’t watch a sunset or YouTube. Yet what your eye sees is but a narrow band in the electromagnetic spectrum. Shorten those light waves and you get invisible gamma radiation. Lengthen them and tune into a radio broadcast.
Discover what’s revealed about our universe as you travel along the electromagnetic spectrum. There’s the long of it: an ambitious goal to construct the world’s largest radio telescope array … and the short: a telescope that images high-energy gamma rays from black holes.
Also, the structure of the universe as seen through X-ray eyes and a physicist sings the praises of infrared light. Literally.
And, while gravity waves are not in the electromagnetic club, these ripples in spacetime could explain some of the biggest mysteries of the cosmos. But first, we have to catch them!

Hi ho, hi ho... it’s out with work we go! As you relax this holiday weekend, step into our labor-atory and imagine a world with no work allowed. Soft robots help us with tasks at home and at the office, while driverless cars allow us to catch ZZZZs in the front seat.
Plus, the Internet of Everything interconnects all your devices, from your toaster to your roaster to … you. So there’s no need to ever get off the couch. But is a machine-ruled world a true utopia?
And, the invention that got us into our 24/7 rat race: Edison’s electric light.
The sweet stuff is getting sour press. Some researchers say sugar is toxic. A new study seems to support that idea: mice fed the human equivalent of an extra three sodas a day become infertile or die. But should cupcakes be regulated like alcohol?
Hear both sides of the debate. Another researcher says that animal studies are misleading, and that for good health, you should count calories, not candy and carbs.
Plus, an investigative reporter exposes the tricks that giant food companies employ to keep you hooked on sugar, salt, and fat.
Also, a listener corrects our pronunciation of Neil Armstrong’s birthplace in the Sounds Abound episode.
It’s Skeptic Check … but don’t take our word for it!
