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 Subtle Mysteries Of Dinosaur Sex

Robert Krulwich NPR

They dominated our planet for 130 million years. You can't do that without having babies, and to have babies, dinosaurs had to have sex. The mystery is — and this is still very much a mystery — we don't really know how they did it.

The key problems being:

First, dinosaur ladies and dinosaur gentlemen were roughly the same size. No big/little asymmetry as with spiders. With spiders, the little fellow mounts the big lady. There are no body-crushing weight issues.

She was 34, on a trip to Europe, got sick from a flu or maybe it was a virus, had to lie down and stay in bed — for months and months. A friend brought her a snail. You might enjoy its company, she was told.

"Why, I wondered, would I enjoy a snail?," Elisabeth Tova Bailey asks in her book The Sound of a Wild Snail Eating. "What on earth would I do with it?"

Mysterious Dancing Lights In Afghanistan

This isn't a painting. It's not from a movie. It's not a strange astronomical event. This is real — what you can see when certain helicopters in Afghanistan touch down on sandy ground, raising dust, causing mysterious arcs of light to loop and dance through the air.

This doesn't always happen. "The halos usually disappear as the rotors change pitch," wrote war photographer Michael Yon. "On some nights, on this very same landing zone, no halos form." How come?

It's high summer, yes, but blink and soon it will be fall, and trees will turn red, brown, beige, yellow, pale green and gold. But not cars. Cars may be making the Earth warmer, but their colors, I notice, have turned wintry.

Take a look at this chart, put together by DuPont. It's their 2012 Automotive Global Color Popularity Report for the planet.

Look What You've Done, North America!

Originally published on Mon August 5, 2013 4:25 pm

This is the story of two continents doing battle, North America versus South America. It is also a biological mystery.

For a very long time, North America and South America were separate land masses. The Pacific Ocean slipped between them, flowing into the Caribbean. The Isthmus of Panama was there, but it was underwater. The two continents didn't touch.

Who Does A Better Wave? Sports Fans Or Hippos?

Robert Krulwich NPR

Professor William Barklow was on vacation when this happened. He was in Tanzania sitting on a river bank gazing about, when all of a sudden a hippopotamus pushed its head out of the river right in front of him, opened its huge mouth and bellowed.

It was really loud. Barklow could feel sound waves hitting his chest, his neck; he could hear the cry echoing along the riverbank. He knew next to nothing about hippos being himself a bird man, a specialist on the North American loon, but he was intrigued by what happened next.
