Geoff Brumfiel

Science editor Geoff Brumfiel oversees coverage of everything from butterflies to black holes across NPR News programs and on NPR.org.

Prior to becoming the editor for fundamental research news in April of 2016, Brumfiel worked for three years as a reporter covering physics and space. 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.

Before NPR, Brumfiel 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.

Researchers may have detected gravitational ripples from the collision of two black holes, according to rumors circulating in emails and on blogs . The Laser Interferometer Gravitational-Wave Observatory (LIGO) is planning a major announcement for Thursday morning. For now, scientists directly involved in the project are staying quiet about what they've seen, but other researchers say it could be a major breakthrough for the fields of physics and astronomy. "Everyone's going to be watching;...

Researchers at Google have developed a program that can excel at the game of "go," which originated in China and is considered a tougher problem for a machine than other strategy games such as chess. The program has defeated the European champion of the game. Now its developers say the same technology may be used to conquer problems in everything from medicine to...

This week, NASA is set to reach a milestone on one of its most ambitious projects. If all goes to plan, workers will finish assembling the huge mirror of the James Webb Space Telescope — an $8 billion successor to the famous Hubble telescope. "So far, everything — knock on wood — is going quite well," says Bill Ochs, the telescope's project manager at Goddard Space Flight Center in Maryland. The massive mirror is being built in a facility that's essentially a giant, ultra-clean gymnasium. NPR...

Researchers have looked in the stomach of an ancient ice mummy and found the remains of the bacteria that lived in his gut. The results, published in the journal Science , suggest that the community of microbes living on and in humans has existed for millennia. Roughly 5,300 years ago, this particular man was hiking across the Oetztal Alps between what's now Italy and Austria when somebody shot him in the back with an arrow. The remains of the fellow, who came to be called...

North Korea was celebratory in its claims that it detonated its first hydrogen bomb on Wednesday. "Through the test conducted with indigenous wisdom, technology and efforts [North Korea] fully proved that the technological specifications of the newly developed H-bomb for the purpose of test were accurate and scientifically verified the power of smaller H-bomb," the country's official news agency reported . But the White House, along with many others, isn't buying it. "The initial analysis is...

Just over a decade ago, Iran had a multi-faceted research program to develop a nuclear warhead that would fit on top of a ballistic missile. That's the bottom line of a new report from the International Atomic Energy Agency (IAEA). The coordinated program ended in 2003, but some sporadic work continued until 2009, the new report says. The report is the strongest statement yet from the nuclear watchdog agency on Iran's past weapons work. Iran is now in the process of scaling back its current,...

And to tell us all about it, NPR science correspondent Geoff Brumfiel is here. Hey, Geoff. GEOFF BRUMFIEL, BYLINE: Hey there. SHAPIRO: What exactly happened this week? BRUMFIEL: So yesterday afternoon, a rocket built by this company Blue Origin, which is owned by Amazon CEO Jeff Bezos, took off from a field in Texas. The rocket traveled more than three times...

Astronomers have spotted what they believe to be the most distant object ever seen in our solar system. The dwarf planet, known for now simply as V774104, is more than 100 times farther from the sun than we are. Astronomers aren't sure what it's doing out there, but they're hoping follow-up studies of its orbit will teach them more. V774104 was first noticed in mid-October. Astronomer Scott Sheppard and his colleagues were using the Subaru telescope in Hawaii to hunt for faint, distant...

One of those companies, Exxon Mobil, has acknowledged that it supported climate change deniers in the past but no longer does. Yesterday, news broke that the giant energy company is under investigation for publicly denying what its own scientists had concluded, that climate change is a result of human...

Climate change isn't just something to worry about here on Earth. New research published today shows that Mars has undergone a dramatic climate shift in the past that has rendered much of the planet inhospitable to life. About 3.8 billion years ago, Mars was a reasonably pleasant place. It had a thick atmosphere filled with carbon dioxide that kept it warm. Rivers trickled into lakes across its surface. Some researchers think there might even have been an ocean. "It seems to have been a much...

Our world is made of matter. "Everything you see and feel — your laptop, your desk, your chair — they are all ordinary matter," says Aihong Tang , a researcher at Brookhaven National Laboratory. But matter has a counterpart called antimatter. Each kind of fundamental particle of matter has an antimatter nemesis lurking in the shadows. And true to science-fiction stereotype, if matter and antimatter ever meet, they annihilate in a flash of light. If you've never run into "antimatter" outside...

A NASA probe will hurtle past Saturn's moon Enceladus on Wednesday, coming to within just 30 miles of the surface. In the process, it will sample mist from a liquid ocean beneath the frozen surface. Doing so may provide clues about whether the ocean can support life. At just 314 miles across, researchers originally expected Enceladus to be a tiny ball of solid ice. But thanks to NASA's Cassini probe , they now know it's somewhere really special. "We're very confident there's a liquid ocean...

http://www.youtube.com/watch?v=ZcxBOQTOb2Q On Thursday morning, Patricia was a relatively small Category 1 hurricane. By Friday afternoon, it was the most powerful storm ever recorded in the Western Hemisphere. Is climate change to blame for this record-breaking storm's ferocious rise? The answer is complex, and shows why it's so hard to tie a single weather event to global warming. Between Thursday and Friday, Patricia underwent what hurricane researchers call " rapid intensification ," a...

No names. No pictures. No direct conversation. And don't touch the plutonium. Those were the ground rules before NPR was allowed a rare opportunity to see nuclear inspectors learning their craft. The inspectors came from the International Atomic Energy Agency , the world's nuclear watchdog. This week, the agency will be looking on as Iran begins to scale back its nuclear program. Under the terms of a multinational agreement, Iran is to dramatically cut its uranium stockpile, mothball much of...

Pluto is not dead. That's the bottom line, according to new research published in the journal Science . The dwarf planet is home to mountains, glaciers and a hazy atmosphere that stretches for a hundred miles above the surface. "It is this really active dynamic world," says Cathy Olkin , the deputy project scientist of NASA's New Horizons mission, which flew past Pluto on July 14. Even though the spacecraft whizzed past Pluto months ago, new results are still coming back. That's...

Mars is cold and dry, but billions of years ago, it was cold and wet. That's according to new evidence from NASA's Curiosity rover , which is currently exploring a large crater on Mars. The rover has found geological evidence that lakes of liquid water existed in the crater 3.5 billion years ago. "The lakes may have existed for hundreds of thousands of years," says John Grotzinger , a researcher at Caltech and chief scientist for the rover. But he adds, the lake network may have stuck around...

Updated at 3:40 p.m. ET A new analysis of data from Fukushima suggests children exposed to the March 2011 nuclear accident may be developing thyroid cancer at an elevated rate. But independent experts say that the study, published in the journal Epidemiology , has numerous shortcomings and does not prove a link between the accident and cancer. The work, led by Toshihide Tsuda of Okayama University, is based on a large public health survey that was set up in Japan's Fukushima...

If you watch the film The Martian, you'll see Hollywood explosions and special effects galore, but you'll also see some serious science. Actor Matt Damon, who plays stranded astronaut Mark Watney, must calculate his way through food shortages, Martian road trips and other misadventures as he fights to find a way off the Red Planet. Numbers are a matter of life and death for Damon's astronaut, and in this movie they're not pulled from thin air. "If you care to double-check the...

Scientists have caught Mars crying salty tears. Photos from NASA's Mars Reconnaissance Orbiter show dark streaks flowing down Martian slopes. The streaks appear in sunny spots or when the weather is warm, and they fade when the temperature drops. Water was suspected to be involved, but now scientists have confirmed its presence. The new analysis, published in Nature Geoscience , shows salts mixed with water when the streaks are darkest. The water disappears when the streaks lighten. "It's...

It's one of the greatest, and most disturbing, questions of the Fukushima disaster: What happened to the nuclear fuel inside the plant? Now physicists are trying to shed some light on the problem using particles from the edge of space. The Fukushima accident was broadcast around the world. On March 11, 2011, an earthquake and tsunami struck the plant, knocking out cooling in three working reactors. The uranium fuel inside melted down. But nobody's quite sure where it went. "Right now we don't...

Learning to make sounds by listening to others is a skill that helps make us human. But research now suggests a species of monkey may have evolved similar abilities. Marmosets have the capacity to learn calls from their parents, according to research published Thursday in the journal Science . The results mean that studying marmosets might provide insights into developmental disorders found in humans. It also suggests that vocal learning may be more widespread than many researchers...

http://www.youtube.com/watch?v=D_723qwjULM In space, food is freeze-dried, prepackaged, and frankly not always very tasty. But on Monday aboard the International Space Station, astronauts got a rare treat: fresh lettuce. The red romaine lettuce was grown by NASA's Veggie project , which has one goal — to bring salad to space. "It's just one of those things that we have to learn if we're going to step into the solar system and go to Mars," says Trent Smith, the Veggie project manager. "How...

The name Hiroshima is so tied to the atomic bomb that it's hard to imagine there were other possible targets. But in early 1945, the U.S. was still months away from building its first bomb and certainly didn't know what to hit. "Should it be a city? Should it be a military installation? Should you be just displaying the bomb, without killing anybody?" These are questions that were yet to be decided, says Alex Wellerstein , a historian at the Stevens Institute of Technology. Wellerstein has...

"I have a hard time saying this with a straight face, but I will: You can teleport a single atom from one place to another," says Chris Monroe , a biophysicist at the University of Maryland. His lab's setup in a university basement looks nothing like the slick transporters that rearrange atoms and send them someplace else on Star Trek . Instead, a couple million dollars' worth of lasers, mirrors and lenses lay sprawled across a 20-foot table. "What they do in the TV show is, they send the...

http://www.youtube.com/watch?v=0AbiygSo478 Scientists with NASA's mission to Pluto revealed stunning new images of the dwarf planet on Friday. Researchers say the pictures suggest an icy world complete with glaciers and "snow" that falls through a wispy atmosphere. The New Horizons spacecraft zipped past Pluto on July 14. It was traveling too fast to stop, but it snapped a trove of photos as it flew by. Because deep-space communication happens at sub-dial-up speeds, it will take months for...
