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

Quoctrung Bui NPR

Originally published on Mon October 6, 2014 2:19 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.

Everything Dies, Right? But Does Everything Have To Die? Here's A Surprise

Adam Cole NPR

A puzzlement.

Why, I wonder, are both these things true? There is an animal, a wee little thing, the size of a poppy seed, that lives in lakes and rivers and eats whatever flows through it; it's called a gastrotrich. It has an extremely short life.

This Blog Is Ending Soon

Robert Krulwich NPR

Originally published on Wed September 24, 2014 7:08 pm

NPR (in the form of a super-top executive) sat me down and, after four years of generously supporting this blog, told me it can't anymore. It needs to cut costs and — you know the phrase — it has chosen to go "in new directions." So at the end of this month, Krulwich Wonders will no longer appear on NPR's website.

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.

Souls Tumbling In The Light

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.

When I was a boy I had a globe. I could take it in my hands, rest it on my lap, give it a spin and look down on Africa, Europe, North America and Asia spinning by.

Building Me: A Puzzlement

Originally published on Fri September 5, 2014 3:01 pm

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.
