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 10:36 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

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?

Gilles Chapdelaine NASA & ESA

Originally published on Tue September 18, 2012 8:53 am

Here's an old, old, question, but this time with a surprise twist. The question is — and I bet you asked it when you were 8 years old and sitting on a beach: Which are there more of — grains of sand on the Earth or stars in the sky?

Obviously, grains and stars can't be counted, not literally. But you can guestimate.

Volcano Shoots Geyser Of Water Up Into Space

Michael Benson

Originally published on Tue October 9, 2012 10:53 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.
