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.

Watts For Lunch? (Or Why Humans Are Like Light Bulbs)

Robert Krulwich NPR

Originally published on Mon June 10, 2013 12:06 pm

There's a new lunch place down the block, so like you do when the menu looks interesting, I walked in and ordered something mysterious, which for me was the "Red Lentil and Edamame Salad," mostly because I can never remember what edamame is, and because that word suggests doing something slightly frightening, like munching accidentally on one's mother.

What Did Rachel Carson Hear? The Mystery Of The 'Fairy Bell Ringer'

Bob Schutz AP

Originally published on Mon June 3, 2013 2:08 pm

This is the season of night noises, chirps, buzzes, little cries. The air is telling you, "Things are going on out here," and if you like you can step out onto the porch and do what the writer Rachel Carson did back in 1956: She played a hunting game. The rules were simple: You stand outdoors, near the house. You go quiet. When you hear something interesting, you either: a) take a flashlight and go hunt for it; or b) you don't go anywhere. You just imagine it.

The best find Rachel Carson ever made, she never found.

Humans do it with smoke.

Dolphins do it with air.

With a little snort, dolphins can produce a nearly perfect "air" rings, (sophisticated non-dolphins called them toroidal vortices) which they turn into underwater toys.

How Benjamin Franklin Invented A Weight Loss Program, Using Balloons

Robert Krulwich and Maggie Starbard NPR

Originally published on Wed May 22, 2013 4:40 pm

Ask a great inventor to invent, and that's exactly what he'll do. Sometimes the ideas pop out like cannon bursts: "consider this ... " or "maybe this?" or "Wait! How about THIS!"

Ben Franklin did that with balloons.

What Did I Do Last Summer? Oh, I Discovered How To Make Babies Without Sex. And You?

Robert Krulwich NPR

Originally published on Fri May 17, 2013 10:26 am

Ah, if only all summers could be like June, July and August 1740 — when three young guys (and a 6-year-old and a 3-year-old) did a science experiment that startled the world. In those days, you could do biology without a fancy diploma. More people could play.

What Is It About Bees And Hexagons?

Robert Krulwich NPR

Originally published on Thu May 16, 2013 12:26 pm

Solved! A bee-buzzing, honey-licking 2,000-year-old mystery that begins here, with this beehive. Look at the honeycomb in the photo and ask yourself: (I know you've been wondering this all your life, but have been too shy to ask out loud ... ) Why is every cell in this honeycomb a hexagon?

Bees, after all, could build honeycombs from rectangles or squares or triangles ...

But for some reason, bees choose hexagons. Always hexagons.
