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.

The Power Of Poop: A Whale Story

Originally published on Mon April 7, 2014 1:46 pm

This, I would think, should be self-evident: Generally speaking, big creatures eat smaller creatures that, in turn, eat even smaller creatures, like this ...

And just as obviously, one would expect the food chain to be pyramid-shaped: a few big creatures at the top eating more middle-sized creatures in the middle, that eat many, many, many little creatures at the bottom, like so:

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

NOVA scienceNOW

Originally published on Sat March 22, 2014 11:19 am

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 ...

What's The Biggest Animal Gathering Ever? (Was Rod Stewart There?)

Robert Krulwich NPR

Originally published on Fri March 21, 2014 10:08 am

It's a small moment in a sprawling Shakespeare play. Most people miss it. A nobleman named Mortimer has been locked up by the king, who decrees: Don't anyone say "Mortimer" in my royal presence. That name is forbidden. But one of Mortimer's allies has a plan. He wants to give the king a little bird, a starling.

An Imaginary Town Becomes Real, Then Not. True Story

Booklist American Library Association

Originally published on Wed March 19, 2014 5:38 pm

This is the story of a totally made-up place that suddenly became real — and then, strangely, undid itself and became a fantasy again. Imagine Pinocchio becoming a real boy and then going back to being a puppet. That's what happened here — but this is a true story.

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

... just up the road from Roscoe and Rockland.

Trees On The Move As Temperature Zones Shift 3.8 Feet A Day

You are a snail. You are a plant. You like where you are. The temperature's right. It suits you.

But then, gradually, over the years, it gets warmer. Not every day, of course, but on more and more days, the temperature climbs to uncomfortable highs, drying you out, making you tired, thirsty.

Can It Be? Pigeons, Geese And White-Tailed Deer Were Once Rare

Robert Krulwich NPR

Originally published on Mon February 3, 2014 4:47 pm

Go back 150 years and ask yourself, what was there a lot of?

We all know the answer ...

There were lots of buffalo, lots of passenger pigeons, lots of oysters. And then, poof! Hardly any. Or none ...

OK, let's flip the question: What were there precious few of 150 years ago, in a couple of cases almost to the point of extinction? The answer — believe it or not — is white-tailed deer, Canada geese and, arguably, ordinary pigeons.

I'm not kidding.

Am I Going To Die This Year? A Mathematical Puzzle

Robert Krulwich NPR

Originally published on Wed January 8, 2014 12:56 pm

A few years ago, physicist Brian Skinner asked himself: What are the odds I will die in the next year? He was 25. 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.

One Man. One Cat. Multiplied

Originally published on Wed February 5, 2014 11:08 am

We start with a man called Mike and a cat called Ella. Two creatures.

Nothing odd about them, except that Mike has a beard and Ella is a touch chunky. Otherwise, they could be any cat and guy. Except ...

When you think about it, no one is ordinary. You could put a totally bland cat-and-guy couple in front of a hundred people, ask them to look, and each one would see a very different pair, different in a thousand subtle ways, because everybody looks at everything with different eyes.

How Important Is A Bee?

Robert Krulwich NPR

Originally published on Fri December 6, 2013 10:37 am

This is an alarming story, not because it ends badly. It's alarming because it ends well. It shouldn't have, but it did, and biologists (and especially conservationists) now have a puzzle to ponder.

The story begins in central China, in an apple-growing region called Maoxian County, near the city of Chengdu. In the mid-1990s, the bees that regularly showed up there every spring suddenly didn't. Apple farmers, obviously, need bees. Bees dust their way through blossoms, moving from flower to flower, pollinating, which helps produce apples in September.

On Thanksgiving, Everybody Needs A Friend — And That Means Everybody

Last December, a website called The Morning News asked me to describe the most important and unimportant events of my year.

Now that it's Thanksgiving, I'm going to post it here because it's about two girls who want the best for everybody — and that can get complicated.

What We Can Never, Ever Know: Does Science Have Limits?

iStockphoto.com

Originally published on Fri September 6, 2013 1:10 pm

I got two books in the mail that, if they could have, would've poked, scratched and ripped each others' pages out. I don't know if Martin Gardner and Patricia Churchland ever met, but their books show that there are radically, even ferociously, different ways to think about science. Gardner died last year. He was a science writer whose monthly "Mathematical Games" column in Scientific American was wildly popular. Patricia Churchland is a philosopher who teaches at U.C. San Diego.

The issue between them is: How much can we know about the universe?
