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.

Is That A Lark I Hear? A Nightingale? Surprise! It's A Bat

Originally published on Mon October 6, 2014 12:19 pm

Bats produce "pings" or "clicks," right? They make these high-pitched sounds, too high for us to hear, but when their cries ricochet off distant objects, the echoes tell them there's a house over there, a tree in front of them, a moth flying over on the left. And so they "see" by echolocation. That's their thing. They are famously good at it.

'Murdersquishing' Them To Death: How Little Bees Take On Enormous Hornets

I know, I know. You have Putin to worry about, ISIS to worry about, Britain's near breaking, Washington's broken, and the globe keeps getting warmer — so why bring up Japanese giant hornets? You have worries enough. But I can't help myself. I've got to mention these hornets because, as bad as they are — and they are very, very bad ...

... this story has a happy ending.

If you have ever seen, or spent time with (or, God forbid, had to live with) a colicky baby, this will make perfect sense to you. It may not make actual sense, but when the baby is crying you don't think very straight.

Every year on Sept. 11, this happens ...

When it gets dark, New York City turns on 88 7,000-watt xenon light bulbs to produce two powerful beams that shoot up, side by side, to remind us that once upon a time, two towers stood here, and then didn't, and this is how we remember the day they came down — by looking up.

Building Me: A Puzzlement

It's a puzzle — the deepest puzzle I know. The question is: What are we?

One answer, from physicist-novelist Alan Lightman, is we are stuff. Just stuff.

What's going on here, I can only guess, but here's what you're about to see: In the video below, the great musician Glenn Gould, supreme interpreter of Bach, is sitting at his living room piano on a low, low chair, his nose close to the keys. He's at his Canadian country house in his bathrobe.

When Venus Was Filled With Venusians — 50 Billion Of Them

Originally published on Thu September 4, 2014 10:13 am

Robert Krulwich NPR

What a difference 180 years makes.

Back in the 1830s, a Scottish minister and amateur astronomer named Thomas Dick tried to calculate the number of intelligent creatures in the universe. He assumed that all heavenly bodies supported intelligent life, maybe not exactly like us, but similar to us in size and habits of living. Then he took population figures for Great Britain and, assuming that space aliens lived just as densely, he projected populations onto various planets.

If You're Born In The Sky, What's Your Nationality? An Airplane Puzzler

Originally published on Wed August 20, 2014 7:52 am

Robert Krulwich NPR

Here's a puzzle I bet you've never pondered.

Imagine you are very, very pregnant. For the purposes of this mind game, you are a married American woman (with an American spouse) and you are about to board a plane and, pregnant as you are, they let you on.

Your flight, on Lufthansa Airlines, will leave Frankfurt, Germany, and travel nonstop to the Maldive Islands in the Indian Ocean. Germany is cold, wet and unhappy-making, and you crave the aquamarine waters, the balmy skies of the Maldives.

Elemental Storytelling

Originally published on Tue August 12, 2014 6:10 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

Originally published on Thu August 7, 2014 11:25 am

Robert Krulwich NPR

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 9:22 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

Originally published on Mon July 28, 2014 5:33 pm

Robert Krulwich/NPR

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?

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

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 ...
