Geoff Brumfiel

Science correspondent Geoff Brumfiel's reports on physics, space, and all things nuclear can be heard across NPR News programs and on

Brumfiel has carried his microphone into ghost villages created by the Fukushima nuclear accident in Japan. He's tracked the journey of highly enriched uranium as it was shipped out of Poland. For a story on how animals drink, he crouched for over an hour and tried to convince his neighbor's cat to lap a bowl of milk. He became a full-time correspondent in March of 2013.

Prior to NPR, Geoff was based in London as a senior reporter for Nature Magazine from 2007-2013. There he covered energy, space, climate, and the physical sciences. In addition to reporting, he was a member of the award-winning Nature podcast team. From 2002 – 2007, Brumfiel was Nature Magazine's Washington Correspondent, reporting on Congress, the Bush administration, NASA, and the National Science Foundation, as well as the Departments of Energy and Defense.

He began his journalism career working on the American Physical Society's "Focus" website, which is now part of Physics.

Brumfiel is the 2013 winner of the Association of British Science Writers award for news reporting on the Fukushima nuclear accident.

He graduated from Grinnell College with a BA double degree in physics and English, and earned his Masters in science writing from Johns Hopkins University.

Harvard roboticist Mike Rubenstein thought he was being clever when he came up with the name for the 1,024 little robots he built. He's into computers, so he thought of kilobytes and named them kilobots.

Tomorrow morning, a European space probe will arrive at a comet with a tongue-twister of a name: Churyumov-Gerasimenko.

Getting there has been proven even trickier than pronouncing it.

The Rosetta spacecraft began its journey way back in March of 2004.

First it swung past Earth to gather speed. Then it catapulted out to Mars, for a boost from that planet's gravity field. Then in 2007, it came back to Earth for another push — then back out to an asteroid, and back to Earth.

It's been a long journey, but it's nearly over. On Wednesday, the European Space Agency's Rosetta spacecraft will finally arrive at the comet 67P/Churyumov-Gerasimenko.

Humans have sent spacecraft hurtling past comets before, but Rosetta is doing something very different. It's sidling up next to 67P to join the big, dirty ice ball on its journey past the sun.

I spent months working with the U.S. Air Force to get access to a remote underground nuclear bunker in Nebraska for our radio series on America's missile forces. There was only one question left to answer before I left.

What did I want for lunch?

The stretch of Interstate 80 between Cheyenne, Wyo., and Lincoln, Neb., is straight and flat. High plains stretch out on either side.

But scattered along this unremarkable road, the Air Force keeps some of its most powerful weapons — Minuteman III nuclear missiles.

The young officers at F.E. Warren Air Force Base have an enormous job: to keep 150 nuclear-tipped missiles ready to launch at a moment's notice.

Understandably, they're expected to know exactly what they're doing.

Three times a month, they're tested on the weapons and the codes used to launch them. Anything less than 90 percent is a fail.

Shortly after news broke that a Malaysia Airlines flight crashed in eastern Ukraine, suspicions began to swirl that the plane had been shot down. NPR's Geoff Brumfiel speaks with Audie Cornish about the feasibility that a missile brought down the airliner.

Physicists have used the world's most powerful laser to zap diamonds. The results, they say, could tell us more about the cores of giant planets.

"Diamonds have very special properties, besides being very expensive and used for jewelrey etc.," says Raymond Smith, a researcher at Lawrence Livermore National Laboratory in California. "It's the hardest substance known to man."

Scientists at the National Institutes of Health made an unpleasant discovery last week as they cleaned out an old laboratory: The lab contained vials of the smallpox virus, previously unknown to authorities. The vials have since been transferred to a secure lab at the federal Centers for Disease Control and Prevention in Atlanta.
