Geoff Brumfiel

Geoff Brumfiel works as a senior editor and correspondent on NPR's science desk. His editing duties include climate and environment, while his reporting focuses on the intersection of science and national security.

From April of 2016 to September of 2018, Brumfiel served as an editor overseeing basic research and climate science. Prior to that, he worked for three years as a reporter covering physics and space for the network. 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. From 2002 – 2007, Brumfiel was Nature Magazine's Washington Correspondent.

Brumfiel is the 2013 winner of the Association of British Science Writers award for news reporting on the Fukushima nuclear accident.

Aric Toler isn't exactly sure what to call himself.

"Digital researcher, digital investigator, digital something probably works," Toler says.

Toler, 30, is part of an Internet research organization known as Bellingcat. Formed in 2014, the group first got attention for its meticulous documentation of the ongoing conflict in Ukraine. Toler used posts to Russia's equivalent of Facebook, VK, to track Russian soldiers as they slipped in and out of eastern Ukraine — where they covertly aided local rebels.

Donna Strickland seemed genuinely surprised to learn that she was only the third woman to ever win the Nobel Prize in physics.

"Is that all, really?" a flummoxed Strickland asked during a press conference announcing the prize. "I thought there might have been more."

STEVE INSKEEP, HOST:

It's a terrifying weapon: a nuclear-powered cruise missile that can fly anywhere on the planet, possibly spewing radioactivity as it goes. In March, Russian President Vladimir Putin announced that his nation had successfully tested just such a machine.

But new satellite imagery of a remote Russian test site suggests that the missile may not be working as well as claimed.

North Korea announced today that it will permanently close a major missile test site. Kim Jong Un, the North's leader, said the site would be dismantled in the presence of international inspectors.

A Swiss laboratory likely involved in analyzing samples from a March chemical attack in Salisbury, England, has reportedly been targeted by Russian agents.

At the Pentagon today, Vice President Mike Pence laid out plans for a new branch of the military in outer space - a Space Force.

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."

Updated: 10:45 a.m. ET

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