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.
