What if Placebos ARE the Medicine? Jul 21, 2023

Show notes

We’ve known about the placebo effects for over 200 years. That’s where doctors give you a pill containing no actual medicine, but you still get better. Recent studies have uncovered a broader range of benefits from the including alleviated pain, nausea, heart rate, hay fever, allergies, insomnia, depression, anxiety, fatigue, and even symptoms of Parkinson’s. Weirder yet, the characteristics of the pill — color, size, and shape — influence their effectiveness. Fake capsules work better than fake pills, and fake injections work best of all. The question is: Just how far can fake treatments go?

The Man Who Invented QR Codes Jul 07, 2023

Show notes

In 1994, Masahiro Hara got tired of having to scan six or seven barcodes on every box of Toyota car-parts that zoomed past him on the assembly line. He wondered why the standard barcode from the 70s was still used...Why couldn’t someone invent a barcode that used two dimensions instead of one that could work from any angle or distance, even even if it got smudged or torn?

And so, studying a game of "Go", he dreamed up what we now know as the QR Code — the square barcode you scan with your phone. It shows up on restaurant menus, billboards, magazine ads — even tattoos and gravestones. But even that, says Hara-san, is only the beginning.

How Doug Lindsay Invented His Own Surgery Jun 09, 2023

Show notes

In his senior year of college, a monstrous ailment fell upon Doug Lindsay. His skin felt flayed. His heart raced. The room spun. He was so weak, he couldn’t sit up in bed, let alone walk. Worst of all, doctors had no idea what was wrong with him.

Only one person on earth had the time and motivation to figure out what was wrong with Doug Lindsay: Doug Lindsay. Over the next 14 years, he consumed medical textbooks and science journals. He attended medical conferences in his wheelchair. He wrote polite, well-informed letters to specialists all over the world. In the end, he not only figured out what was wrong with him—he invented a new surgery that he thought would fix it. He was right.

The Power of an Empty Metal Box May 26, 2023

Show notes

We’ve been shipping stuff across oceans for centuries. But until 1956, we loaded our ships in the dumbest way possible: one at a time. Then Malcolm McClean came along. He envisioned lifting the big metal box part off a truck and setting it directly down onto a ship. Every one of these boxes would be identical and interchangeable, maximizing space and minimizing waste. The shipping container was born — an idea that was so powerful, it rejiggered the global economy, gutted cities, and turned China into the world’s manufacturer.

From Klingon to Dothraki: Constructed Languages for Hollywood May 12, 2023

Show notes

The first time you heard “Star Trek” characters speak Klingon, or the “Game of Thrones” characters speaking Dothraki and High Valyrian, you might have assumed that the actors were just speaking a few words of gibberish, created by some screenwriter to sound authentic. But these are complete languages, with vocabulary, syntax, grammar, and even made-up histories. There’s only one person on the planet whose full-time job is creating them—and these days, he’s swamped with requests. No doubt about it: Conlangs (constructed languages) are the new special effect. Me nem nesa!

Hear from David Peterson (author, linguist & full-time language maker), Mark Okrand (author, linguist & creator of Klingon), and Angela Carpenter, (linguistics professor at Wellesley College).

The Million-Dollar Toothpaste Tube Apr 28, 2023

Show notes

We’re overrun with plastic. It’s in our oceans, our water, our food. Something has to be done—preferably by corporations, which churn out millions of tons of plastic every year.

Enter: the toothpaste tube. It might seem like a minor player in the plastic problem, but we throw 20 billion toothpaste tubes into the landfill every year. Recycling plants can’t take them, because they’re made of plastic and metal foil bonded together. They all end up in the landfill.

Colgate, the #1 toothpaste brand, decided to tackle the problem. It spent five years and millions of dollars to design a tube made of the same plastic milk jugs are made of—the easiest-to-recycle plastic in the world—with no metal foil. The new tube is indistinguishable from existing tubes—except the whole thing can go into the recycle bin.

And then—Colgate gave away the patent. Today, 90% of the world’s toothpaste makers are switching to recyclable toothpaste tubes. This is the uplifting, surprising, and slightly hilarious story.

The Rewilded Farm Mar 31, 2023

Show notes

After 17 years of trying to prop up their failing farm outside of London, Charlie Burrell and Isabella Tree were stressed, exhausted, and $1.7 million in debt. They decided to stop farming—no more plowing, planting, irrigating, chemicals. They gave away the farm—to nature.

20 years later, their land has one of the most important biodiversity hotspots in the UK. These 3500 acres teem with species, many of which are endangered or hadn’t been seen in the UK for centuries. And the twist: Their land now generates more money than it ever did as a farm.

Similar rewilding experiments are under way in 30 countries. They offer protection for nearby farms, corridors of safety for animals—and buffers against climate disasters for us.

NASA Redirects an Asteroid Mar 17, 2023

Show notes

65 million years ago an asteroid struck the earth. In the ensuing planetary darkness, the dinosaurs went extinct. But the dinosaurs didn’t have a space program! Now we can spot incoming asteroids with steadily improving confidence. If we see one on a collision course with the Earth, we know from the movies that the solution is to nuke it...Right? Actually, NASA has a better idea. If you can just nudge an asteroid slightly off its current path, maybe 25 or 50 years before it hits us, it won’t hit the earth. It will sail harmlessly past us. In 2022, NASA put that idea to the test. It sent a tiny spacecraft 7 million miles into space, for the express purpose of crashing into a known asteroid—to see if we could bump it into a different path. We quickly found out. This is the story of the DART (Double Asteroid Redirection Test) mission.

Hear from Dr. Richard Binzel, MIT professor. Dr. Elena Adams, lead engineer for NASA’s DART mission, and Dr. Lori Glaze, director of NASA’s planetary science division.

How They Found the Shipwreck Endurance Mar 03, 2023

Show notes

In 1915, British explorer Sir Ernest Shackleton’s historic expedition to Antarctica stalled when floating ice trapped, crushed, and finally sank his ship, Endurance. Shackleton’s men survived 21 months on the ice, alone and freezing, and became one of the most incredible adventure stories ever recorded. The ship itself, Endurance, was not seen again for 106 years. Every attempt to find it wound up thwarted by exactly the same enemy: crushing sheets of pack ice. Finally, in 2022, an international team of explorers and scientists found the wreck—and it’s in absolutely pristine condition. This is the story of how they found it.
