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.

President Trump Monday announced his intention to create a "space force" that would oversee the military's activities off-world.

"When it comes to defending America, it is not enough to merely have an American presence in space," Trump said at a meeting of the National Space Council, which oversees the nation's space policy. "We must have American dominance in space. So important."

Experts have been left scratching their heads over one of the most concrete concessions President Trump says he received from North Korean leader Kim Jong Un during Tuesday's summit in Singapore.

At a press conference after their meeting, Trump said Kim had agreed to destroy "a major missile engine testing site."

North Korea closed its nuclear test site in spectacular fashion Thursday, blasting the site in what one observer described as a "huge explosion."

NASA and the U.S. Department of Energy say they have successfully tested a new type of nuclear reactor that could one day provide juice to colonies on other worlds. The reactor can power several homes and appears able to operate in harsh environments.

Former weapons inspectors say an apparent trove of information on Iran's nuclear weapons program will increase pressure for more intrusive inspections of its atomic sites.

On Monday, the Israeli government disclosed it had obtained thousands of pages of documents and nearly 200 CDs' worth of data on Iran's nuclear program.

As chemical weapons inspectors wait to investigate an alleged strike near the Syrian capital of Damascus, former inspectors say the challenges the current team faces are daunting.

The inspectors arrived in Syria on April 14, on a mission to investigate a suspected chemical attack in the Damascus suburb of Douma seven days earlier. Unconfirmed reports from the scene suggest that dozens may have died.

The type of nerve agent used to poison a former Russian spy and his daughter in the U.K. was developed in a top-secret laboratory in Moscow and was once a closely held secret of the Russian government.

Sergei Skripal and his daughter, Yulia, were found slumped on a bench in the city of Salisbury on March 4. Experts quickly assessed that Skripal — a former Russian intelligence official accused of spying for the British — had been poisoned with a nerve agent.

On Monday, British Prime Minister Theresa May named the agent in a speech before Parliament.

As the news broke of a school shooting in Parkland, Fla., on Wednesday, hundreds of Twitter accounts believed to be under Russian sway pivoted.

Many had been tweeting about places like Syria and Ukraine — countries where Russia is seeking to strengthen its influence. Suddenly the accounts shifted to hashtags like #guncontrol, #guncontrolnow and #gunreformnow. Tweets mentioning Nikolas Cruz, the name of the shooting suspect, spiked.

The Trump administration released a report on the state of America's nuclear weaponry on Friday. The assessment, known as a Nuclear Posture Review, mainly concerns U.S. nukes and missiles.
