Geoff Brumfiel

Geoff Brumfiel works as a senior editor and correspondent on NPR's science desk. His editing duties include science and space, 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.

Acclaimed physicist Freeman Dyson, who pondered the origins of life, interstellar travel and many other topics, died Friday at the age of 96.

His daughter Mia Dyson told NPR that her father died after a short illness.

Freeman Dyson was known for groundbreaking work in physics and mathematics but his curiosity ranged far beyond those fields.

The U.S. has begun deploying a new type of low-yield nuclear warhead aboard some ballistic missile submarines, according to a report by an independent monitor.

When the USS Tennessee, an Ohio-class submarine, went on patrol in the final weeks of 2019, it carried "one or two" of the new weapons, according to a post by the Federation of American Scientists.

A rocket from the commercial company SpaceX lifted off on Wednesday morning with some 60 satellites aboard. Once they reached low Earth orbit, the satellites were released and began to fan out like a deck of cards.

They follow predictable paths around the Earth, but along the way those paths can cross with other things in orbit — satellites from other companies, old rocket stages, loose bits of metal — and cause a catastrophic collision.

New imagery from commercial satellites that was shared with NPR suggests Iran is making repairs and preparing for a space launch, following a recent string of failed attempts.

The imagery, taken Sunday by the commercial firm Planet and shared via the Middlebury Institute of International Studies at Monterey, shows vehicles parked at a building used to assemble Iran's space rockets at the Imam Khomeini Space Center in northern Iran. A second group of vehicles is visible at a circular launch pad that was heavily damaged during failed launch preparations last year.

On the same night that Iran launched a ballistic missile strike against bases used by U.S. troops in Iraq, a Ukrainian jetliner crashed near Tehran, killing all 176 people onboard. Iranian authorities have said the plane suffered a mechanical failure, but the U.S. and other Western governments believe it was shot down, possibly by mistake.

"The evidence indicates the plane was shot down by an Iranian surface-to-air missile," Canadian Prime Minister Justin Trudeau said during a news conference Thursday. "This may well have been unintentional."
