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.

How Human Beings Almost Vanished From Earth In 70,000 B.C.

Robert Krulwich NPR

Add all of us up, all 7 billion human beings on earth, and clumped together we weigh roughly 750 billion pounds. That, says Harvard biologist E.O. Wilson, is more than 100 times the biomass of any large animal that's ever walked the Earth. And we're still multiplying. Most demographers say we will hit 9 billion before we peak, and what happens then?

Charles Darwin And The Terrible, Horrible, No Good, Very Bad Day

Aaron Birk

I guess everybody, even the smartest people who ever lived, have days when they feel dumb — really, really dumb. Oct. 1, 1861, was that kind of day for Charles Darwin.

In a letter to his friend Charles Lyell, Darwin says, "I am very poorly today," and then — and I want you to see this exactly as he wrote it, so you know this isn't a fake; it comes from the library of the American Philosophical Society, courtesy of their librarian Charles Greifenstein. Can you read it?

It says:

Whoah! You know the feeling, right?

First off, this lizard? It's not really a lizard. It's an almost vanished species, a reptile like no other.

Weekend Special: When Cities, People and Highways Glow Like Stars

Justin Wilkinson NASA via TheChive

In this video, we are flying over the Earth, looking down and seeing what astronauts see when it's nighttime, when lightning storms flash like June bugs, when cities look like galaxies, when you can see where people are. It's quietly astonishing.

This montage of space footage was assembled and narrated by NASA scientist Justin Wilkinson. There's another one, which takes us around the Earth in daytime.

Obama's Secret Weapon In The South: Small, Dead, But Still Kickin'

Ron Blakey Northern Arizona University

Look at this map, and notice that deep, deep in the Republican South, there's a thin blue band stretching from the Carolinas through Georgia, Alabama and Mississippi. These are the counties that went for Obama in the last election. A blue crescent in a sea of red.

Are Those Spidery Black Things On Mars Dangerous? (Maybe)

Michael Benson NASA/JPL/University of Arizona/Kinetikon Pictures

You are 200 miles directly above the Martian surface — looking down. This image was taken by the Mars Reconnaissance Orbiter on Jan. 27, 2010. (The color was added later.) What do we see? Well, sand, mostly. As you scroll down, there's a ridge crossing through the image, then a plain, then dunes, but keep looking. You will notice, when you get to the dunes, there are little black flecks dotting the ridges, mostly on the sunny side, like sunbathing spiders sitting in rows. Can you see them?
