Geoff Brumfiel

Science correspondent Geoff Brumfiel's reports on physics, space, and all things nuclear can be heard across NPR News programs and on NPR.org.

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 European Space Agency is about to try to put a probe where none has gone before: on the surface of a comet.

Humans have never landed anything on a comet's surface. That may change tomorrow.

The European Space Agency's Rosetta mission is poised to send out a small probe to land on a comet known as 67P/Churyumov-Gerasimenko. Rosetta spent 10 years chasing the comet before arriving in August.

The dream of hundreds of space tourists was dealt a blow last Friday when Virgin Galactic's experimental SpaceShipTwo broke up over California's Mojave Desert. The pilot was injured and the co-pilot died in the accident.

But many are still holding on to their tickets.

Evolution has shaped every part of the body, and that includes our private parts. New research published this week sheds light on how the penis evolved and how it forms in different animals.

The research might also one day help illuminate a medical mystery: Birth defects of the penis have risen sharply in recent decades, and nobody is sure why.

Penises weren't necessary when our early ancestors lived in the ocean. A female could lay eggs, and a male could just swim by and excrete some sperm. It would all mix and fertilize in the water.

"My own personal opinion is that time is a human construct," says Tom O'Brian. O'Brian has thought a lot about this over the years. He is America's official timekeeper at the National Institute of Standards and Technology in Boulder, Colorado.

To him, days, hours, minutes and seconds are a way for humanity to "put some order in this very fascinating and complex universe around us."

In what could be a major setback for commercial space tourism, a manned spaceship has crashed in California's Mojave Desert.

The Virgin Galactic Spaceship Two was on a test flight this morning, with two pilots aboard. Minutes after its rocket fired, the company announced on Twitter that spacecraft experienced an "anomaly."

Capt. Tom Ellison of Kern County Fire Department said that Spaceship Two had a malfunction shortly after it separated from White Knight Two, the rocket that gives Spaceship Two a lift up to 45,000 feet.

A careful examination of frozen caribou poop has turned up two never-before-seen viruses.

The viruses are hundreds of years old: One of them probably infected plants the caribous ate. The other may have infected insects that buzzed around the animals.

The findings prove viruses can survive for surprisingly long periods of time in a cold environment, according to Eric Delwart, a researcher at Blood Systems Research Institute in San Francisco.

A European spacecraft orbiting a distant comet has finally answered a question we've all been wondering: What does a comet smell like?

"It stinks," says Kathrin Altwegg, a researcher at the University of Bern in Switzerland who runs an instrument called ROSINA that picked up the odor.
