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

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.

On Thursday, researchers announced the discovery of gravitational waves --wrinkles in the very fabric of space-time.

But behind the headlines and news conferences were decades of hard work, hundreds of scientists and more than a billion dollars in taxpayer funds.

Far from our galaxy, in the vast darkness of space, two massive black holes merged into a single, larger hole.

And now researchers say they have detected rumblings from that cataclysmic collision as ripples in the very fabric of space-time itself. The discovery comes a century after Albert Einstein first predicted such ripples should exist.

A computer has bested humanity at one of the most complex strategy games ever devised.

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.

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.

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.

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.

Big news this week in commercial space travel. And to tell us all about it, NPR science correspondent Geoff Brumfiel is here. Hey, Geoff.


SHAPIRO: What exactly happened this week?

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.

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.
