Robert Krulwich

Robert Krulwich is a correspondent for NPR's Science Desk, reporting on the intersections of science and technology with culture, politics and religion. His specialty is explaining complex news — economics, technology, science — in a style that is clear, compelling and entertaining. "I like talking about 'invisible ideas' and trying to find a way to explain what you've learned so people can grasp it," he said.

Additionally, Krulwich co-hosts WNYC's NPR-distributed scientific documentary series Radio Lab with host/producer Jad Abumrad and serves as substitute host on NPR news magazines and talk programs including Morning Edition, All Things Considered and Talk of the Nation.

Krulwich first joined NPR in 1978 and served as economics reporter until 1985 when he joined CBS News. Since 1994, Krulwich has been an ABC News correspondent, appearing regularly on Nightline, World News Tonight and Good Morning America. He contributed to NPR occasionally until his recent return to NPR.

With Ted Koppel, he co-hosted an eight-part primetime series "Brave New World," which probed the "eight biggest questions facing humankind." With Peter Jennings, he produced an animated history of Bosnia for a children's special. With Barbara Walters, he explored possible cures for cancer.

Krulwich has been called "the most inventive network reporter in television" by TV Guide, "the man who makes the dismal science swing" by the Washington Journalism Review, and "the man who simplifies without being simple" by New York magazine.

He is also a regular correspondent on the PBS investigative series Frontline where he won an Alfred I duPont-Columbia University Award for his coverage of campaign finance in the 1992 presidential campaign, a national Emmy Award for his investigation of privacy on the Internet, "High Stakes in Cyberspace"; and a George Polk Award for an hour on the savings and loan scandal. His ABC special on Barbie, a cultural history of the world-famous doll, also won a national Emmy.

Krulwich has also anchored a cultural affairs series on PBS (and a simultaneous series on the BBC) called The Edge. He has also hosted Live From Lincoln Center and appeared on Jay Leno's premiere Tonight Show broadcast.

Once a year Krulwich hosts a semi-fictional year-in-review called "Backfire," with friends Jane Curtin, Buck Henry and Tony Hendra. In 1995, the group performed at the White House at the invitation of President and Mrs. Clinton.

He has received numerous awards for his reporting, including the Extraordinary Communicator Award from the National Cancer Institute in 2000, four consecutive Gainsbrugh Awards from the Economics Broadcasting Association, and the American Association for the Advancement of Science Excellence in Television Award in 2001 for a NOVA special on the human genome. TV Guide named Krulwich to its All Star reporting team; and Esquire placed him in its Esquire Registry in 1989. In 1974, Krulwich covered the Watergate hearings for Pacifica Radio and in 1976, he was Washington bureau chief for Rolling Stone magazine.

Krulwich received a bachelor's degree in U.S. history from Oberlin College in 1969, and a Juris Doctorate from Columbia Law School in 1974. He lives in New York City with his wife, Tamar Lewin, a national reporter for the New York Times. They have two children, Jesse and Nora Ann.

Lucretius, Man of Modern Mystery

Lucretius, circa 55 B.C.
Spencer Arnold Getty Images

Before he became a Professor of literature at Harvard, and way before he wrote his classic Shakespeare biography, Will in The World, Stephen Greenblatt was an I'll-read-anything kind of kid. One day, he was standing in the campus book store, and there, in a bin, selling for ten cents (good price, even in 1961) he noticed a thin, little volume called On the Nature of Things, by a Roman writer named Lucretius.

Living Very, Very Narrowly

Courtesy of Jakub Szczesny Centrala

There are two apartment buildings in my Manhattan neighborhood that share a block. They sit very close. One is about nine inches from the other. In the small vertical space between them, a horde of finches have built themselves nest upon nest upon nest rising for nine human floors. It's a finch skyscraper. In March and April you can see finches busily flying in and out of this vertical crack, bearing twigs, grasses and nest-building material.

When Does A Person Start To Boil?

Lev Yilmaz

It's hot. I know, I know.

But, have you ever wondered how much heat you can take?

232 years ago, three British gentlemen decided to find out.

They designed a room, sealed it off, and heated it to 211 degrees, that's one degree shy of water-boiling hot.

What would happen, they wondered, if they stepped in and stayed? Could they take 211 degrees? How about 212? How about higher?

At what point does a person start to boil? These were very daring gentlemen. And just to make it more interesting, they brought three other "subjects" into the room:

Getouttamyway! (Thoughts On City Traffic)

I've been to Rome, so I've seen the dark side: a traffic intersection where everybody decides to get where they're going at the same time, so no one gets anywhere. Cairo might be even worse. This isn't a parking lot, it's a street...

City people are always pushing; if you think you won't get caught, you keep moving. The rules don't matter. The signs don't matter.

Something isn't right here. There are creatures among us — a puppy named Snoopy, a boy named Charlie Brown, a wild dagger-haired tempest called Calvin — who don't ever, ever, ever grow up. They're not allowed.

They come from a corner of the universe where puppies, boys and tigers live and dream until the day whoever created them says, "enough." After that, they don't die (at least, not in the usual way,) they get recycled and go on forever.

Nature's Secret: Why Honey Bees Are Better Politicians Than Humans

Originally published on Tue October 23, 2012 4:49 pm

Adam Cole NPR

In the spring, bee hives get so rich with honey, so crowded with baby bees, they often burst in two. Some bees stay in the original nest with a new queen, but a second group, led by the old queen, heads off to establish a new home. If there's a cloud of bees hanging by a tree branch in your back yard, that's them — the house hunters.

How do they choose a new home?

Strange Things Happen To Guys Who Wear Pants

Vin Liota for NPR

As a general matter, animals move, plants don't.

That's why this time of year plants launch their seeds into the moving air, catching springtime breezes, or take advantage of sparrows, pigeons, seagulls, sheep, shaggy dogs, and attach their seeds to moving animals.

You and I, of course, are moving animals, and I think you'll be surprised by the number of seeds we matter-of-factly and totally unconsciously carry with us as we wander about. The numbers are a little startling.

Case in point: men's pants.

The Loneliest Plant In The World

One day in 1895, while walking through the Ngoya Forest in Zululand, southern Africa, a botanist with the oh so suitable name of John Medley Wood caught sight of a tree. It sat on a steep slope at the edge of the woods and looked different from the other trees, with its thick multiple trunks and what seemed like a splay of palm fronds on top. From a distance it looked almost like a palm tree, and Dr. Wood — who made his living collecting rare plants (he directed a botanical garden in Durban) had some of the stems pulled up, removed, and sent one of them to London.

Had he stayed here in New York and hung out with me a lot, Jonah might be a lot less skinny because I am not at all skinny and in Jonah's latest blogpost on Frontal Cortex, he reports that when skinny people spend a lot of time with non-skinny people, they tend, for some strange reason, to get fatter.

Carbon In Love

In this episode, No. 4 of our carbon series, we get to the heart of the matter.

If there's a growing concentration of CO2 in our atmosphere, (and there is) why does that make the planet warmer?

In our cartoon and in the slideshow below, you see the CO2 molecule getting hit by the heat energy from bouncing light. And instead of breaking up, it just gets excited (the chemical equivalent of getting warmer). That's essentially the chemical explanation for global warming.

Chewing On Carbon: The Celery Question

Once again, the subject is carbon. So far we've been celebrating carbon's ability to bond with other atoms. Today we get violent — and break those bonds.

When you eat a carrot, set fire to a piece of paper, or put a match to a lump of coal, carbon atoms are being yanked, juggled and ripped out of each other's embrace. People have gotten very good at breaking carbon bonds: that's how we light our cities, drive our cars, power our tools. But let's look at this from carbon's point of view...
