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.

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?

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.

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.

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.

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.

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.

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.

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.

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.

Today the Nobel Prize in physics was awarded to two researchers. Takaaki Kajita, of Japan, and Arthur McDonald, of Canada, won for showing that particles called neutrinos have mass. NPR's Geoff Brumfiel has more on the win.

This is Nobel Prize season, and this morning comes the prize in physics. Joining me in the studio is NPR science correspondent Geoff Brumfiel. Geoff, good morning.


GREENE: All right, so who won?

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.

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.

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.

Now to space, and we'll take the elevator. The U.S. Patent Office has granted a patent for a freestanding space elevator tower. The idea of a space elevator has long captured the imaginations of writers, from Arthur C. Clarke to Roald Dahl.

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 thought.

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.
