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.

Intriguing Lime-Green Blobs Appear In The Andes Mountains. Are They Alive?

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.

How To Marry The Right Girl: A Mathematical Solution

Robert Krulwich NPR

Originally published on Thu May 15, 2014 2:34 pm

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

Robert Krulwich NPR

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

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."

Plants Talk. Plants Listen. Here's How

Robert Krulwich NPR

Originally published on Wed April 30, 2014 10:06 am

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 ...

'Don't Touch Me,' Said Canada. 'I Won't!' Said The U.S.A. So They Moved 20 Feet Apart

National Film Board of Canada. Photothèque / Library and Archives Canada

Originally published on Fri April 25, 2014 6:55 pm

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.

Introducing A Divorce Rate For Birds, And Guess Which Bird Never, Ever Divorces?

There is love. And then there's albatross love.

In his new book, The Thing With Feathers, Noah Strycker says albatrosses have a knack for coupling. "These globe trotters, who mate for life and are incredibly faithful to their partners, just might have the most intense love affairs of any animal on our planet," he writes.

So This Is How They Do It! Zebras Getting Stripes

Ricardo Solis

Originally published on Sat April 19, 2014 12:42 pm

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.

'Why Am I Dead?' He Never Asked. Here's The Answer He Never Heard

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.

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:

'Oh, Hello,' Says Andrew, As He Suddenly Grabs You By The Leg Or Neck

Andrew Ucles YouTube

Originally published on Thu April 3, 2014 2:22 pm

Some people like a nice walk, some a gentle run, others a cup of tea. But not Andrew Ucles. There is nothing relaxed about Andrew. You can find him chasing after wild animals on his videos, grabbing them with his bare hands and then, while they squiggle, scratch and lunge, he tells them, "Settle, settle," shows them to the camera, brags a little and lets them go.

You Yawn. She Doesn't Yawn Back. Uh-Oh

Robert Krulwich NPR

Originally published on Wed March 26, 2014 6:44 pm

You are at a table for two, sitting with your girlfriend or boyfriend, when, for no good reason (you can't help it, you didn't mean to do it), you yawn. It's a big, gaping, jaw-extending, embarrassing yawn and because you didn't cover your face, oh, God, she/he sees it. A second or two goes by, and then ... something doesn't happen. Your girlfriend/boyfriend doesn't yawn back.

Should you be alarmed?
