Music, Inside Out

Friday, May 10, 2013

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 doub...

Moths That Drive Cars (Really)

Thursday, May 09, 2013

What you are about to see — and I'm not making this up — is a moth driving a car.

That's right. A silk moth — actually, 14 different male silk moths — each, in turn, hooked up to a robotic vehicle at Dr. Noriyasu Ando's lab at the ...

Moths That Drive Cars (Really)

Thursday, May 09, 2013

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.

Wildlife That Isn't Wild And Isn't Alive

Wednesday, May 08, 2013

Bit by bit, bot by bot, robots are slipping into the real world. Yes, they are born in science labs, but more and more, they're joining us outdoors, up in the sky as drones or spybots (looking like swifts swooping across a meadow), or swimming in the ocean (

Our Very Normal Solar System Isn't Normal Anymore

Tuesday, May 07, 2013

Some things you just count on. Like if we ever meet a space alien, it should have eyes (and maybe a head). Like somewhere out there, there are planets like ours. Like we have an ordinary solar system — "ordinary" because you know what it looks like ...

The Boomerang Rocket Ship: Shoot It Up, Back It Comes

Tuesday, April 30, 2013

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 st...

The Boomerang Rocket Ship: Shoot It Up, Back It Comes

Tuesday, April 30, 2013

What in heaven's name is happening here?

We're in McGregor, Texas, surrounded by farms (and the ghost of Johnny Cash). There, on a launch pad, is a 10-story rocket ready to take off. Its engines ignite. Up it goes, higher, then higher, then higher still, until at 820 feet, something ...

Nobody Throws Balls Like Yu

Saturday, April 27, 2013

He's 26 years old, comes from Japan, plays baseball in Texas and can throw pitches like no one else in the game. He's Yu Darvish and he throws fastballs, sliders, slow curves. Facing him — and this is the thing that makes him bigger than baseball, just a stunning athlete ...

Mysterious Silly Putty Devours Innocent Magnets

Tuesday, April 23, 2013

If you're old enough to remember the movie The Blob, starring a gelatinous, oozing menace that gooped its way across floors, slid under doors, attached itself to an exposed foot, hand, arm and then devoured its screaming victim without making even a swallowing sound ... If you liked The ...

A Wet Towel In Space Is Not Like A Wet Towel On Earth

Sunday, April 21, 2013

You just don't know (because who's going to tell you?) that when you leave Earth, travel outside its gravitational reach, hundreds and hundreds of everyday things — stuff you've never had to think about — will change. Like ... oh, how about a wet wash cloth?

Monkeys, Mai Tais And Us

Saturday, April 20, 2013

Some of us can't say no — and I'm using "us" in the broadest sense, to include not just humans, but wallabies, fruit flies, birds and monkeys. We can't control our appetites.

There are monkeys, Charles Darwin wrote in his book The Descent of Man, who "have a strong taste ...

Trees On Top Of Skyscrapers? Yes! Yes, Say I. No! No, Says Tim

Friday, April 19, 2013

This isn't finished. But it will be. Two residential towers, dense with trees, will have their official opening later this year in downtown Milan, Italy, near the Porta Garibaldi railroad station. (The image is not a photograph, but an architect's rendering. The towers are built and the trees are ...

Put away that old Rand McNally map — it's time for a new way to see what America really looks like.

A 'Whom Do You Hang With?' Map Of America

Wednesday, April 17, 2013

Look at the center of this map, at the little red dot that marks Kansas City. Technically, Kansas City is at the edge of Missouri, but here on this map it's in the upper middle section of a bigger space with strong blue borders. We don't have a name for ...

Who Stands Where In A Crowded Elevator And Why?

Tuesday, April 16, 2013

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?

Who Stands Where In A Crowded Elevator And Why?

Tuesday, April 16, 2013

She's in Finland now, getting her Ph.D. at the University of Jyvaskyla, but before that, when she was in Adelaide, Australia, she studied elevator behavior. Rebekah Rousi hung around two tall office towers in town, riding elevators up and down day after day, looking for patterns. When a bunch ...

Is This Science Journalism? Nah. Then What Is It?

Thursday, April 11, 2013

Journalism may not be the right word for this. It's a kind of reporting. What you see here is true, and carefully edited.

It's not art, though the images are sharp and concentrated.

It's more than advertising, (though that's its purpose) because it is telling you something abstract and true ...

The images are sharp and concentrated. But this isn't art, it's more than advertising, and it's not quite education. It's an invitation.

Don't Go Near The World's Champion Rainbow Watcher. It's Mean. Very Mean

Wednesday, April 10, 2013

A few months ago on Radiolab, we did an hour on color, which included a segment on rainbow watching. We imagined a man, a dog, a sparrow and a butterfly all gazing at the same rainbow and we asked: How many colors does each see?
