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.

Humanity has snapped detailed portraits of planets and moons throughout our solar system. But there's one missing from the album: Pluto.

Although Pluto was discovered in 1930, it has remained stubbornly hard to photograph. The Hubble Space Telescope has taken the best pictures, and frankly, they stink.

NASA is about to launch a new spaceship into orbit, and Mallory Loe has never heard of it.

"I mean, technically, NASA doesn't have another spaceship, do they?" she asks incredulously during a visit to the Smithsonian National Air and Space Museum in Washington, D.C.

She's hardly the only one who doesn't know about this new spacecraft. In fact, none of a half-dozen tourists NPR interviewed in the museum's lobby was aware of the Orion spaceship.

It was the first ever landing on a comet, and it was perfect.

Unfortunately, that wasn't the end of the journey for the European Space Agency's unmanned Philae lander. After touching down on Comet 67P/Churyumov–Gerasimenko, the lander bounced off the surface and flew a kilometer back up into space.

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.

Researchers have successfully decoded the genes of a 45,000-year-old man from Siberia. The results offer clues about early human life outside of Africa as well as how humans interacted with Neanderthals and other groups around at the time.

The complete set of genes is the oldest genome of its kind, according to Svante Pääbo, a director at the Max Planck Institute for Evolutionary Anthropology in Leipzig. "It's almost twice as old as the next oldest genome that has been sequenced."

The Nobel Prize in physics was awarded Tuesday to three Japanese-born researchers for their work on the blue light-emitting diode, or LED.

And there's never been a better time to put their Nobel-prize winning discovery right in your own home. LED light bulbs, which use blue LEDs, are coming of age, and the price is dropping fast. You can pick them up for less than $10 each.

Dr. David Kuhar landed in Dallas on Tuesday night.

Kuhar is the Centers for Disease Control and Prevention's top expert on Ebola, and the agency dispatched him as soon as they received confirmation that a man had carried the disease from Liberia.

Today, his 10-person team is on the front lines of an effort to keep that single case from turning into an outbreak.

Earlier this week, two spacecraft arrived at the planet Mars. One came from India, the other from the U.S. Both are now in orbit and collecting data. But the Indian probe is conducting its mission at a tiny fraction of the cost of its NASA counterpart.

"Some of the publicly available numbers are in the $74 million to $75 million range," says Amaresh Kollipara, a managing partner of Earth 2 Orbit, a company that pairs private satellite providers with the Indian space agency.

The tiny, island nation of Iceland is in the middle of a growth spurt. For the past month, the country's Bardarbunga volcano has been churning out lava at a prodigious rate. And the eruption shows no signs of abating.

Earlier this week NASA announced that two private companies will build spaceships to take astronauts to the International Space Station. NASA hopes that both models will eventually be used by space tourists to get into orbit. Which got us wondering, which one would we rather fly in?

Over the past month, the U.S. has begun to ramp up aid to Ebola-stricken countries in West Africa. U.S. contributions could soon top $250 million dollars, according to the White House National Security Council.

You might wonder what kind of aid is being provided. So did we. Here's a sampling, drawn from information provided by the U.S. Agency for International Development, the Department of Defense and the Centers for Disease Control and Prevention:

As the body count in Africa's deadly Ebola outbreak continues to rise, some say the time has come for the U.S. military to step in.

"The U.S. Military is uniquely poised to help with this disease," says Timothy Flanigan, an infectious disease researcher at Brown University who's volunteering in Liberia, the country hardest hit by Ebola. "We've trained for it, we've got the logistics, we've got the support and we have the matériel."

Space is a dangerous place. That message resonated again on Monday, when the Russian Federal Space Agency — Roscosmos — announced that a team of experimental geckos tasked with copulating while in orbit did not survive their journey.

"All geckos, unfortunately, died," the space agency said in a terse statement.

Roscosmos is launching an investigation into the exact circumstances surrounding the geckos' deaths, but the mission seemed star-crossed from the start.

Air pollution is clogging the skies of our planet. Now one scientist thinks Earth may be just one of many polluted worlds — and that searching for extraterrestrial smog may actually be a good way to search for alien intelligence.

"People refer to 'little green men,' but ETs that are detected by this method should not be labeled as green," says Avi Loeb, an astronomer at Harvard University.

The idea of finding alien polluters may be a bit of a long shot, but Loeb says it's possible.

Harvard roboticist Mike Rubenstein thought he was being clever when he came up with the name for the 1,024 little robots he built. He's into computers, so he thought of kilobytes and named them kilobots.
