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.

The Pentagon Wants These Robots To Save The Day

NASA's RoboSimian is among the robots taking part in the Defense Department competition. The Space Agency may one day use it to explore caves on other planets.

On Friday, 24 robots and their masters will be going head-to-head in California for a $2 million prize. The robotics challenge is sponsored by the Pentagon's Defense Advanced Research Projects Agency (DARPA).

Those fearing the Pentagon-sponsored prize could signal the dawn of Terminator-style cyborgs needn't worry. "Even though they look like us, and they may look a little bit mean, there's really nothing inside," says Gill Pratt, the program manager running this competition. "What you're really seeing is a puppet."

Scientists Cast Doubt On An Apparent 'Hiatus' In Global Warming

A fully loaded container ship sails along the coast. Historically, ships have taken most of the sea measurements that go into the estimate of Earth's average surface temperature.

Originally published on Fri June 5, 2015 5:31 pm

A team of government scientists has revised its estimate for how much the planet has been warming.

The new results, published in the journal Science, may dispel the idea that Earth has been in the midst of a "global warming hiatus" — a period over the past 20 years where the planet's temperature appears to have risen very little.

CDC Investigates Live Anthrax Shipments

A security fence surrounds the main part of the U.S. Army's Dugway Proving Ground, a testing laboratory in the Utah desert. The Army says it mistakenly shipped live anthrax from Dugway to several labs in the U.S. and Korea.

The Centers for Disease Control and Prevention is still trying to figure out how the military managed to ship anthrax spores that were apparently live from one of its facilities to more than a dozen labs across the United States.

"We have a team at the [military] lab to determine what may have led to this incident," says CDC spokesman Jason McDonald. In addition, he says, the agency is working with health officials in nine states to make sure the potentially live samples are safely disposed of and the labs affected are decontaminated.

After 25 Years, The Hubble Space Telescope Still Wows Humanity

(Left) This is one of two cameras that the telescope originally carried, and it has since been replaced with a more up-to-date version. (Right) Workers study Hubble's 8-foot main mirror. After launch the mirror was found to have a problem, which astronauts corrected in 1993.

Mike Massimino is one of the last people to ever see the Hubble Space Telescope in person.

From inside his orbiting space shuttle, the telescope first appeared on the horizon as a star, says Massimino, who was an astronaut on the final mission to service the space telescope in 2009.

The Space Station Gets A Coffee Bar


Originally published on Wed April 15, 2015 11:14 am

In space, all they have is instant.

"For an instant coffee, it's an excellent instant coffee," says Vickie Kloeris, who manages the space station's food supply for NASA. Astronauts are allotted up to three freeze-dried cups (pouches, actually) a day, and Kloeris says it's "extremely popular."

But, she adds, "Can it compete with brewed espresso? No."

After Snowden, The NSA Faces Recruitment Challenge

Originally published on Tue March 31, 2015 7:16 am

Daniel Swann is exactly the type of person the National Security Agency would love to have working for it. The 22-year-old is a fourth-year concurrent bachelor's-master's student at Johns Hopkins University with a bright future in cybersecurity.

And growing up in Annapolis, Md., not far from the NSA's headquarters, Swann thought he might work at the agency, which intercepts phone calls, emails and other so-called "signals intelligence" from U.S. adversaries.

A Day's A Day The World Around — But Shorter On Saturn

Saturn has a rocky surface, but it's deep beneath the clouds. That makes it hard to tell exactly how long the day is.

Originally published on Tue April 14, 2015 1:38 pm

Researchers have answered a question that has been nagging them for years: Exactly how long is a day on the planet Saturn? The result (10 hours and 32 minutes or so) was published this week in the journal Nature, and could teach scientists more about the giant, ringed planet.

Researchers Think There's A Warm Ocean On Enceladus

A new analysis suggests that Enceladus' ocean is being heated from the bottom up. That could explain plumes of ice seen at its south pole.

Originally published on Tue March 31, 2015 5:07 pm

Saturn's moon Enceladus is a mystery. From Earth it looks tiny and cold, and yet it's not a dead hunk of rock. Passing spacecraft see trenches and ridges, similar to Earth's, and in 2005 NASA's Cassini mission spotted ice geysers streaming from its south pole.
