Mums bloom in the fall, daffodils in spring, roses in summer. How do farmers get such different plants to bloom simultaneously in Winter for Valentine's Day? It's done, strangely, with short, sudden flashes of light.

A new video technology that amplifies small color changes and slight movements can, when pointed at people, tell what's going on inside.

Banishments are much more complicated than they used to be. And this "Minute Physics" video suggests, paradoxically, that both you and the person you banish are somehow simultaneously at the center of the universe.

If DNA molecules are the Marilyn Monroes of biochemistry — everybody knows what DNA looks like — what about proteins? Why do most people have no idea what a protein looks like? Well, maybe this will help: proteins that look like houseflies, Bedouins, bumblebees and a pair that look uncannily like Moses and the Burning Bush.

Something amazing is about to happen: you can claim a little piece of history by naming our long-lost common ancestor. We're not kidding -- the scientists who discovered the creature want your help, so we're holding a contest. Go!

Normally a plate can't get a job at the circus. It's just a plate. But here's a plate that can swoop through the air, catch a flying pole, and balance it upright, midair! In other words, a circus-worthy plate. Artificial Intelligence is the science of making dumb things do smart-looking stuff.

Here's something new, exciting and just a little bit troubling: it's a little robot that you can fly with your phone. It's easy. It's versatile. It's got cameras so you can see and record what's going on in the apartments above you, the houses on your block, in backyards, sports fields. Nice, yes. But what happens to privacy if these things become very popular?

One blizzardy February afternoon, Jad and a handful of Radiolabbers headed to midtown Manhattan to meet a fleet-fingered string quartet.

The politics of beehives might be able to teach our Congressional leaders a little bit about governing.

Radiolab's been thinking about asteroids for one of our upcoming shows, and it turns out, now so is the rest of the world. Click here for where to watch.

On three different occasions, the candidate with the most votes didn't become president of the United States. We call this "The Electoral College Problem." Here's a solution. Simple. Mathematical. Rational. (With one small "but ...")

Last year a guy in San Francisco jumped on a bicycle, clicked on his GPS, clicked on an app, snapped on his helmet, and 27 miles, two and a half hours and many calories later, he'd etched a Valentine message onto a street map of San Francisco. That was nice. Now, a year later, it's getting really interesting.

A channel on YouTube lets you see what goes on deep in the bowels (excuse the expression) of a natural history museum. There are dead things in jars, drawers and basements, but best of all, there's Emily, who hosts the show. She's a volunteer curatorial assistant/storyteller who could make a thumbtack interesting.

Lulu Miller's advice for taking the edge off that unrequited love this Valentine's? Send a letter to Verona, Italy, where an office of 20 volunteers replies to thousands of notes about love and heartbreak every year.

Everybody knows you need a chicken to lay an egg. Everybody knows you need an egg to produce a chicken. What nobody knows is how the cycle started. Here's a new take, that leans eggwards — and it's fun to watch.

Drop a cat from a bed, a chair or a tree, and it will do its wriggly thing and land on all four feet. Cats are famous for this. But we've discovered an animal that does it better. Meet the new champ.

Take a boot, take a glove, take a brick, take a pan, take a car roof, spray it with this new nano-tech substance and strange things will happen. Very strange things.

In our Speed episode, we learn just how outdated our idea of the stock market is. Producer Andy Mills helps us picture the modern-day market with some beautiful depictions of high frequency trading, from technicolor graphs to frantic piano riffs.

SPOILER ALERT: if you haven’t listened to our Speed show yet, go do that right now, before you read any further. Then, take a look at some mind-bending behind-the-scenes images from the physicist in our "Master of the Universe" story.
