Robert Krulwich

Robert Krulwich works on radio, podcasts, video, the blogosphere. He has been called "the most inventive network reporter in television" by TV Guide.

Krulwich is a Science Correspondent for NPR. His NPR blog, "Krulwich Wonders" features drawings, cartoons and videos that illustrate hard-to-see concepts in science.

He is the co-host of Radiolab, a nationally distributed radio/podcast series that explores new developments in science for people who are curious but not usually drawn to science shows. "There's nothing like it on the radio," says Ira Glass of This American Life, "It's a act of crazy genius." Radiolab won a Peabody Award in 2011.

His specialty is explaining complex subjects, science, technology, economics, in a style that is clear, compelling and entertaining. On television he has explored the structure of DNA using a banana; on radio he created an Italian opera, "Ratto Interesso" to explain how the Federal Reserve regulates interest rates; he has pioneered the use of new animation on ABC's Nightline and World News Tonight.

For 22 years, Krulwich was a science, economics, general assignment and foreign correspondent at ABC and CBS News.

He won Emmy awards for a cultural history of the Barbie doll, for a Frontline investigation of computers and privacy, a George Polk and Emmy for a look at the Savings & Loan bailout online advertising and the 2010 Essay Prize from the Iowa Writers' Workshop.

Krulwich earned a Bachelor of Arts degree in history from Oberlin College and a law degree from Columbia University.

Lights, Lights, Lights, Action! A Crazy New Light Projector

What can you do with a spotlight?

You can light a spot.

But what if you give yourself more options and invent a tool that lets light spill, splash or tighten into a beam as thin as a pencil line — a beam of light that can draw!

Draw what? Oh my God, so many things: a galloping unicorn, a friendly girl, a guy who kicks you in the face, a wormhole, a ball that splashes into a fluid, a cube, a spiral, a rabbit, a squid, a scribble.

How We Learned That Frogs Fly

Originally published on Wed June 11, 2014 10:51 am

Robert Krulwich NPR

There are places where frogs could be — but aren't.

And places where frogs could be — and are.

Ninety years ago, scientists were debating the question of animal dispersal. How come there are kangaroos in Australia, and none in southern Africa --which seems, environmentally, very kangaroo-friendly? Certain frogs show up in warm ponds in one part of the world, but warm ponds a thousand miles away have none. Why?

A Little Bird Either Learns Its Name Or Dies

Robert Krulwich NPR

I've been wondering lately, do animals invent names? As in names for themselves? Names for each other? I've always thought that what we do when we call ourselves "Ralph" or "Laura" is unique, something exclusively human. But it turns out that's wrong. Other animals have name-like calls that they use much like we do. I've posted about this before (regarding horses, dolphins and little parakeets) ...

A Young Woman Falls In Love With Everything

Xiangjun Shi Vimeo

You start with difference, with mystery. Some things spiral, some become spheres, some branch, some don't. We know that inert atoms quicken, become bees, goats, clouds, then dissolve back into randomness. We look at these things, all these very, very different things, and we wonder, are they really different, or is every thing we see one thing, expressed differently? Does the universe have rules? How many? Could there be a single generating principle, a oneness?

Jupiter's Dot And Mine. Why Life Is Unfair

When I was 9, my dad drew this picture of me. You will notice something on my left cheek — a little brown spot.

That's a mole. The doctor called it "a birthmark." My mom called it "a beauty mark." I was born with it. Having grown up before supermodel Cindy Crawford became famous, I was not familiar with the allure of beauty marks and, anyway, I'm a guy. My mom said it was hardly noticeable. I didn't believe her.

Far, far, far away is a great place to be — if you want to stay marvelous. There is a plant, called Welwitschia mirabilis (mirabilis being Latin for marvelous), found only one place on Earth. You can get there, as artist/photographer Rachel Sussman did, by driving through the vast emptiness of the Namibian desert, the Namib Naukluft, in Africa.

Oops.

Someone dropped lime sherbet on the desert — and it's melting. Who's going to clean this up?

Nobody. Because this — believe it or not — is a plant. It may look like a glob of goo, but it's not at all gooey. It's solid to the touch — so solid that a man can lie on top of it and not sink in, not even a little.

Poor Johannes Kepler. One of the greatest astronomers ever, the man who figured out the laws of planetary motion, a genius, scholar and mathematician — in 1611, he needed a wife. The previous Mrs. Kepler had died of Hungarian spotted fever, so, with kids to raise and a household to manage, he decided to line up some candidates — but it wasn't going very well.

Draw My Left! No, No, My Other Left! A Hidden Bias In Art History Revealed

Originally published on Wed May 7, 2014 9:48 am

Robert Krulwich NPR

Look at this guy.

He is half-smiley, half-frowny. I drew the mouth carefully to make it equal parts sad and happy.

But when you look at him — take him in whole — would you say he's having a good day or a bad day?

Most people would say: good day. He seems a little more smiley than not.

That's because, says science writer Sam Kean, when we look at somebody, the left side of that person's face is more emotionally powerful and "determines the overall emotional tenor."

They don't have eyes. Or ears. Or what we would call a nervous system. But plants can talk. And they listen. Let me show you how.

First, we'll need a plant eater. This one's perfect: It's an aphid, a hungry little critter who loves to munch on fresh, green leaves ...

Next, we arrange lunch. We choose a bunch of young, healthy bean plants with lots of broad, green leaves ...

The U.S. and Canada may be as lovey-dovey as two neighbors can get, but according to this charming video history by CGP Grey, both countries agreed to tuck themselves a little bit in, 10 feet back for America, 10 feet back for Canada, creating a corridor of open, surveillable, clear space between them.

How did it happen? How'd the zebra get its stripes?

In Rudyard Kipling's version, a gray, horsey-looking beast went into "a great forest 'sclusively full of trees and bushes and stripy, speckly, patchy-batchy shadows," stayed there awhile, and after a "long time"... got stripy.

OK. Not bad.

Robert Krulwich NPR

Shara Yurkiewicz is a med student. She's doing rounds now, moving from department to department. Much of what she sees, she's seeing for the first time. Not yet a doctor, there are moments, many moments when she has the eyes of a patient. She gets scared. She feels helpless. She's too involved. She's at that place in her training where everything is so sharp, so new, she feels the full, fresh stab of it, and sometimes, very privately, she bleeds.

I Can't Believe What I'm Seeing: A Springtime (Froggy) Miracle

Two weeks ago this animal was frozen solid. If you found one in the woods, packed in the topsoil, hiding under a leaf, you could pull it from the ground and it would feel like an ashtray. You could bang it (lightly) on a table — it would go, "Konk!" like a rock. It doesn't seem to be breathing. It reacts to nothing. It's so dead. Or seems to be. And then, this (I want to call it a miracle) happens ...

It's about a place in upstate New York called Agloe. You can see it here, circled in blue ...

What got him wondering about this, I have no idea, but, hey, it's something everybody asks. When I can't wedge my dental floss between my two front teeth, I ask it, too. So Brian looked up the answer — there are tables for this kind of thingand what he discovered is interesting. Very interesting. Even mysterious.
