Geoff Brumfiel

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

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.

The blast was picked up by seismic stations all over the world, and it was big.

The rain just won't stop. More than two days after Hurricane Harvey made landfall on the Texas coast, the downgraded storm continues to dump water across the region.

So much rain has fallen in the Houston area that the National Weather Service has had to revamp its charts.

Climate researchers agree that climate change can be partially to blame for the devastation. Here's how it has (and hasn't) shaped the course of the storm.

Eclipses are among the most predictable events on the planet. This one was known about for many decades before it crossed the U.S. earlier Monday.

Accordingly, people had been planning eclipse road trips for weeks in advance. They piled into planes and cars and made their way to the 70-mile-wide swath of land where the total eclipse would be visible. They checked online calculators, which told them the time of totality down to the second.

This week saw a dramatic escalation of tensions on the Korean Peninsula. As North Korea promised to engulf the U.S. territory of Guam in "enveloping fire", President Trump tweeted that the U.S. military is "locked and loaded" should North Korea "act unwisely".

The North's missile and nuclear programs have been shrouded in secrecy for years, but recent tests have shed more light on their capabilities. Here is what's currently known.

North Korean missiles can reach the continental United States.

Later this month, the moon's shadow will fall on Carhenge.

"Holy cow man, guess what? There's going to be an eclipse," says Kevin Howard, the head of the visitor's bureau for Alliance, Neb., which is home to the Stonehenge replica made of cars.

North Korea's nuclear arsenal may be advancing faster than analysts had once thought.

Editor's note, Aug. 10: An earlier version of this story said the draft climate report had been leaked by The New York Times, which has since updated its coverage to reflect that a version of the report was made available by the nonprofit Internet Archive in January.


A draft government report on climate says the U.S. is already experiencing the consequences of global warming. The findings sharply contrast with statements by President Trump and some members of his Cabinet, who have sought to downplay the changing climate.

A massive iceberg the size of Delaware has broken free from Antarctica and is floating in the sea.

Earlier Wednesday, scientists announced that the 6,000-square-kilometer (about 2,300 square miles) iceberg had come loose, after satellites detected it had calved off the Larsen C ice shelf on the Antarctic Peninsula.

It was time for Emily Harrington to make a choice.

Harrington is a professional climber. In 2014, she was trying to reach the top of the tallest peak in Southeast Asia, a little-known mountain called Hkakabo Razi that had been successfully climbed only once before.

The morning that the space shuttle Columbia was supposed to return home, Wayne Hale was at the landing site. At age 48, Hale was an up-and-coming manager with NASA. He'd just taken a job overseeing shuttle launches. But since this was a landing day, he didn't have much to do.

And let's follow up on a warning about U.S. security. Former CIA Director Jim Woolsey laid it out yesterday on this program talking of one way that North Korea could use a nuclear device.

Experts are increasingly confident that a powerful nerve agent was used to kill and injure victims in an attack on a rebel-held region of Syria on Tuesday.

More than 70 people were killed in a bombing in Idlib province, according to the Syrian Observatory for Human Rights. The organization says that the death toll so far includes 20 children.

Elsewhere in the province, more than 30 people were reported killed in conventional attacks.

The most expensive part of doing business in outer space is getting there. The private space flight company SpaceX thinks it can change all that, and Thursday's successful reuse of a rocket was a big test of its business model.

SpaceX launched a communications satellite from the Kennedy Space Center in Florida using a rocket stage that had already been to space and back. SpaceX is betting that this kind of recycling will lower its costs and revolutionize space flight.

President Trump's head of the Environmental Protection Agency says he does not believe that carbon dioxide is a major cause of global warming.

"I would not agree that [CO2] is a primary contributor to the global warming that we see," Scott Pruitt said Thursday in an interview with CNBC's Joe Kernen.
