Every night you lose weight while you sleep. Everybody does. Sometimes two pounds. Something inside you when you close you eyes is gone by morning. It's not bathroom-related. It's something else. What could it be?
What's that beetle doing to that beer bottle? The beetle dropped down from the sky, grabbed the bottle's bottom, keeps hugging and hugging it, even when being attacked by ants, and it won't — refuses to — let go. It can't be the beer it's after. The beer is at the other end. What's going on?
Take something old, familiar and classical, add denim, polyester and glasses, and watch what happens! Two French artists create a new form of time travel.
Death, it appears, prefers gentlemen to ladies. Women don't just outlive men, they consistently outlive men at every stage of life. More boys die in utero, in infancy, in adolescence, in middle age, at every stage. That's why nature makes more of them. But why? What's so fragile about guys?
India has just banned dolphin entertainment parks. They are "morally unacceptable," says a government ministry. Meanwhile, on the other side of the planet, the U.S. Navy announced that 24 dolphins trained to sniff for underwater mines will be replaced by robots.
Moving north: two vans. Moving east: three taxis, a peddle cab and one lady walking. Moving west: six motorcycles, another taxi, a truck and a van. Moving south: a bicyclist, two cabs and a truck. All of them meet and there are no rules. Who lives? Who dies?
Take a bunch of broccoli, or make it a Slurpee, burger, pizza and fries, swallow, and ask yourself, "How much energy did I just consume?" Enough to light a flashlight? Run an electric toothbrush? If I were a lunch-eating light bulb, how long would I glow? Here's the answer.
Be really careful when you carve your name onto an ancient Egyptian temple. Not because it's wrong (which it is), but because sometimes the temple comes back to haunt you. The true story of Luther Bradish, an American spy who didn't keep his secret.
Join us for a night of nanospectucular wonders, hosted by Robert Krulwich, live from the World Science Festival tonight (May 30) at 8pm ET here on radiolab.org. Watch below, and join two Radiolab producers for a live chat as the event gets underway.
Take a metronome. Then take another. Then another. Set them ticking at different times. Look. Lift. (That's the key part.) Watch. Then Laugh. Because you will be dumbfounded.
What do you get when you get a college diploma? To hear David Foster Wallace tell it, you get a muscle that will help you forever after — in shopping lines, overcrowded parking lots, in traffic jams. This muscle, he says, frees you when the world gets painfully dull.
Sex is nice, but can animals make babies without it? One summer, two little boys, their tutor and the tutor's two friends did an experiment to explore this question. What they discovered, back in 1740, shocked the world.
Bees could build flat honeycombs from just three shapes: squares, triangles or hexagons. But for some reason, bees choose hexagons. Always "perfect" hexagons. Why?
What would it be like to be a string that made music? Not anything simple, like a guitar string or a cello string, but a magical string, a sine curve that's taut then loose, that doubles then doubles again, that sheds then dissolves into showers of notes.
Welcome to the New World in which, no kidding, insects run robots. In this case, 14 moths take 14 drives in a wheeled vehicle and steer right to the target. Seeing is believing.
SpaceX calls it the "Grasshopper" — it's a rocket that doesn't fall back to Earth haphazardly after launch. It carefully returns itself to the launchpad standing up, right where it started.
Put away that old Rand McNally map — it's time for a new way to see what America really looks like.
When a bunch of people get into an elevator, do they segregate in any predictable way? Do tall ones stand in the back? Do men stand in different places than women? Who looks where?
