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.

Elemental Storytelling

Originally published on Tue August 12, 2014 8:10 pm

There's a photograph I know that shows a kid's bicycle lying on its side, one wheel turned upright, a smear of blood tracing its path on the concrete. There's a little package still latched to the back, waiting for its owner to return. You can see where the bike swerved, then lost its way. Someone's been hurt. Or worse. The blood is still damp, the trail fresh. Whose blood was it? A child's, I imagine — from an accident? A shooting? The photo was taken by Annie Leibovitz during a war in Yugoslavia.

How To Cross 5 International Borders In 1 Minute Without Sweating

Robert Krulwich NPR

Originally published on Thu August 7, 2014 1:25 pm

So many nations are breaking up. Ukraine is in pieces. Moldova is teetering. Libya has no government to speak of. Sudan broke in two last year; now both sides are fighting. Yugoslavia is seven countries. Nigeria has a Christian/Muslim split. Syria has split so many ways it's barely there. Even Scotland is thinking of ditching Great Britain. With every break, we get new lines, new fences, new borders — further evidence of our failure to amalgamate, to get along.

The more borders we have, the more quarrels, the more wars. That's one way to think about borders — they're trouble.

Guess Who's Been Waiting In The Lobby For A Hundred Million Years?

Originally published on Mon August 25, 2014 11:22 am

Sometimes the quiet ones surprise us.

Take moss — those fuzzy green pads you see on the sides of old trees, or hanging onto rocks. Who notices moss? It's just ... there, doing whatever it does — so slowly, so terribly slowly, that nobody bothers to think about it. Moss creeps up tree bark, sits quietly on crevasses in rocks. Moss is an old, old life form, one of the earliest plants to attach to land around 450 million years ago. It's very patient, very modest — but when you look closely, you discover it has super powers.

Pow! Crunch! Zap!

Where The Birds Are Is Not Where You'd Think

Robert Krulwich/NPR

Originally published on Mon July 28, 2014 7:33 pm

This is a trick question. Where would you expect to find the greatest variety of birds?

Downtown, in a city?

Or far, far from downtown — in the fields, forests, mountains, where people are scarce?

Or in the suburbs? In backyards, lawns, parking lots and playing fields?

Not the city, right?

An Animal Makes A $10,000 Deposit, But Not At The Bank

Editor's note: We've added an update at the bottom of this post with results of the auction. Read on!

It's a highly specialized category to be sure: "Longest." But that's what the auctioneer is selling. According to the catalog of I.M. Chait Gallery, in Beverly Hills, "This truly spectacular specimen is possibly the longest example of coprolite ever to be offered at auction."

What's Better Than A Total Eclipse Of The Sun? Check This

NASA/JPL-Caltech

Originally published on Tue July 22, 2014 2:54 pm

Any eclipse is worth seeing. A total eclipse — where the moon completely blots out the sun, where day turns to night, where solar flares ring the moon's shadow like a crown of flame — that's the eclipse everybody wants to see, the alpha eclipse that eclipses all the other eclipses. Everybody knows this (me included), until I saw this ...

Neil Whosis? What You Don't Know About The 1969 Moon Landing

Robert Krulwich NPR

Originally published on Sun July 20, 2014 1:29 am

Forty-five years ago, this week, 123 million of us watched Neil and Buzz step onto the moon. In 1969, we numbered about 200 million, so more than half of America was in the audience that day. Neil Armstrong instantly became a household name, an icon, a hero. And then — and this, I bet, you didn't know — just as quickly, he faded away.

"Whatever Happened to Neil Whosis?" asked the Chicago Tribune in 1974.

The Most Astonishing Wave-Tracking Experiment Ever

Originally published on Mon July 14, 2014 9:58 am

I'm standing on a beach and I see, a few hundred yards out, a mound of water heading right at me. It's not a wave, not yet, but a swollen patch of ocean, like the top of a moving beach ball, what sailors call a "swell." As it gets closer, its bottom hits the rising shore below, forcing the water up, then over, sending it tumbling onto the beach, a tongue of foam coming right up to my toes — and that's when I look down, as the wave melts into the sand and I say,

"Hi, I'm from New York. But what about you? Where are you from?"

Her Baby Is At Risk: Lauren's Story

Originally published on Mon June 30, 2014 3:55 pm

They're odds. That's all they are. Not fate, just probabilities. Lauren Weinstein, cartoonist, is having a baby, and she's told — out of the blue — that she and her husband are both carriers of the gene that causes cystic fibrosis. They are sent to a genetic counselor. What happens next — told in five beautifully drawn, emotionally eloquent cartoons — tells what it's like to walk the edge for a few weeks. She's so many things (sad, funny, scared, puzzled), and then there's the ender. Take a look.

What Not To Serve Buzzards For Lunch, A Glorious Science Experiment

Robert Krulwich NPR

Originally published on Thu June 26, 2014 5:07 pm

OK, I'm doing great science experiments. We've done sex (see previous post). On to lunch!

This is the story of a bird, a puzzle, and a painting. The painting, curiously, helped solve the puzzle, which is: How do vultures find food?
