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.

Getting Slower And Slower: How Slow Can You Go?

Vincent Liota

Originally published on Fri September 21, 2012 8:36 am

Before we go slow, let's go fast, so fast you can't go any faster. That would be light in a vacuum, traveling at 670 million miles per hour ...

Light, of course, can slow down. When light passes through water, it loses speed. A diamond is an even better speed bump. It can slow a beam of light by 40 percent.

But moving on, you and I are going pretty fast right now, though we don't notice. The planet we're on is zipping around the sun at 66,000-plus miles per hour ...

U.S. Explodes Atomic Bombs Near Beers To See If They Are Safe To Drink

National Technical Information Service via Alex Wellerstein

Originally published on Wed September 19, 2012 1:34 pm

So you're minding your own business when all of a sudden, a nuclear bomb goes off, there's a shock wave, fires all around, general destruction and you, having somehow survived, need a drink. What can you do? There is no running water, not where you are. But there is a convenience store. It's been crushed by the shock wave, but there are still bottles of beer, Coke and diet soda intact on the floor.

So you wonder: Can I grab one of those beers and gulp it down? Or is it too radioactive? And what about taste? If I drink it, will it taste OK?

Volcano Shoots Geyser Of Water Up Into Space

Michael Benson

Originally published on Tue October 9, 2012 8:53 am

What we have here is a moon — a small one (slightly wider than the state of Arizona) — circling Saturn.

If you look closely, you will see a small splay of light at its top, looking like a circular fountain.

That's because it is a fountain — of sorts. A bunch of volcano-like jets are sending fantastically high geysers of water vapor up into the sky, so high that you can see them in this remarkable print by Michael Benson, back lit by light bouncing off of Saturn.

What's With Frosty? Why Isn't He Showing Up On Time?

Check out this graph of America's "Growing Season" — it measures the number of continuous days and nights when it never gets below 32 degrees. You could call this our "frost-free" time of year. In many places, the frost-free season begins in the spring and ends somewhere in October.

As you can see, over the 20th century, it's been staying frost-free longer...and longer...and longer...

Which Is Bigger: A Human Brain Or The Universe?

Robert Krulwich NPR

Originally published on Tue July 24, 2012 10:46 am

This is one of those fun-to-think-about questions. A brain isn't much to look at, after all. It's about the size of your two fists put together, three pounds to hold, but oh my, what it can do.

With our brains, we can think backwards, imagine forwards, conjure, create things that don't exist, leap vast distances. For example, suppose I say to you, close your eyes and imagine this:

Weekend Special: Guess What? Sweat Is Not Smelly! (So Why Do I Smell?)

The Chemical Heritage Foundation via YouTube

Originally published on Mon July 9, 2012 10:28 am

It's hot today. Really, really, hot; over a 100 degrees Fahrenheit hot, and so I'm sweating.

Sweating is what we people do to cool off, which is good. But sweating is also what makes me ... what's the word? Odoriferous. (Latinate for stinky, which is not so good.)

Showing Vultures A Little Love

Originally published on Wed August 1, 2012 9:32 am

Think of a giraffe lying on the Serengeti plain. He has just died, maybe of disease, maybe he was killed by a pride of lions, but now he's a 19-foot-long, 4,000-pound mound of meat, which very soon is going to stink and rot and muck up the neighborhood.

To Map Or Not To Map The Brain? That's Tonight's Question

Thomas Deerinck and Mark Ellisman Portraits of the Mind

Originally published on Mon April 2, 2012 9:35 am

"Mind is such an odd predicament for matter to get into," says the poet Diane Ackerman. "If a mind is just a few pounds of blood, dream and electric, how does it manage to contemplate itself? Worry about its soul? Do time and motion studies? Admire the shy hooves of a goat? Know that it will die?

...How can a neuron feel compassion?"

Yes, how?

Neuroscientists Battle Furiously Over Jennifer Aniston

Stephen Lovekin, Carlos Alvarez, Kevin Winter Getty Images

Originally published on Fri March 30, 2012 12:54 pm

Think of Jennifer, or as we like to call her, "Jen." Jen of the dazzling smile, Jen of the gorgeous chin, Jen with her hair down, Jen tousled, Jen as Rachel, Jen with Brad; Jen without Brad, Jen with Vince, Jen at the Oscars, and, of course, Jen as a neuron in the medial part of the temporal lobe.

Maybe you missed that last Jen.

A few years ago, a UCLA neurosurgeon named Itzhak Fried, while operating on patients who suffer from debilitating epileptic seizures, discovered what he now calls the "Jennifer Aniston Neuron."
