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.

Dr. Scott Atlas has literally written the book on magnetic resonance imaging. He has also co-authored numerous scientific studies on the economics of medical imaging technology.

New satellite photos show the aftermath of Tuesday's massive, deadly explosion at the port of Beirut.

As the coronavirus continues to spread rapidly throughout the U.S. and beyond, many are wondering: How on earth will this end? In an interview televised this week, President Trump reiterated his belief that sooner or later the virus will burn itself out. "I will be right eventually," the president told Fox News host Chris Wallace. "It's going to disappear, and I'll be right."

It is called herd immunity, and it's a concept some leaders and scientists have considered when it comes to responding to this pandemic. NPR's Geoff Brumfiel reports on what exactly this idea is and why it presents troubles.

The first thing to know about a new comet that has appeared in the evening sky is that it's one big ice ball: about 5 kilometers (3.1 miles) across.

"Just to put it into context, about 65 million years ago there was an asteroid or a comet that was thought to have caused the extinction of the dinosaurs," says astronomer Amy Mainzer. "That object is thought to have been about 5 to 10 kilometers across."

NASA astronauts are heading to space from U.S. soil for the first time in nine years, aboard SpaceX's Dragon capsule, the maiden crewed flight of the innovative spacecraft.

The mission, which is sending Doug Hurley and Bob Behnken to the International Space Station, is a bold new venture for the space agency's plan to allow commercial companies to take its astronauts into low-Earth orbit.

Updated at 5:40 p.m. ET

NASA and SpaceX were ready to launch a pair of astronauts from U.S. soil for the first time in nearly nine years on Wednesday, but the weather had other ideas.

This week, NASA and the commercial company SpaceX are set to launch two astronauts to the International Space Station (ISS) in a new capsule. This is the first launch by NASA of astronauts from U.S. soil in nearly a decade, but it's happening in the middle of a pandemic.

Here are some of the ways that the coronavirus will, and won't, change the plans for the space agency's latest launch.

Astronauts have been quarantining since before it was cool.

If you want to visit the Great Pyramids or the Great Wall or the Taj Mahal, forget it.

Egypt, China and India are just a few of the dozens of countries that have imposed strict travel restrictions to keep visitors, and the coronavirus, out. An analysis by NPR based on data from the International Air Transport Association found that more than three-quarters of the world's nations and territories have suspended travel from at least one other place.

Over the past week, President Trump and his team have repeatedly claimed to have intelligence showing that the new coronavirus accidentally escaped from a lab in China.

Virus researchers say there is virtually no chance that the new coronavirus was released as result of a laboratory accident in China or anywhere else.

The assessment, made by more than half-a-dozen scientists familiar with lab accidents and how research on coronaviruses is conducted, casts doubt on recent claims that a mistake may have unleashed the coronavirus on the world.

President Trump is ready to reopen America - at least parts of it where the coronavirus appears to be less of a problem.

It's a strange and tragic pattern in some cases of COVID-19: The patient struggles through the first week of illness, and perhaps even begins to feel a little better.

Then suddenly they crash.

The new coronavirus is killing hundreds each day and swamping hospitals around the world. But catching the disease does not mean you will end up in the ICU.

"There are many patients that are fine and that are at home," says Michelle Ng Gong, the chief of critical care medicine at the Montefiore Health System in New York City. Those who don't need a hospital make up "I would dare say, in fact, the vast majority of people," she says.

North Korea appears to be expanding a key rocket launch facility it once pledged to dismantle, according to new satellite imagery shared exclusively with NPR.

The imagery, taken by commercial company Planet and shared via the Middlebury Institute of International Studies at Monterey, shows new roads under construction at the Sohae Satellite Launching Station.

Who should get tested for the coronavirus? The federal government advises that only certain groups should receive tests. But as NPR's Geoff Brumfiel reports, experts say testing must be far broader before the pandemic is under control.

Stay inside, don't meet with friends, don't go to work — these are the messages coming from public health officials at every level of government. But increasingly, experts say they believe those stark warnings must be augmented with another message:

If you think you might be sick, even a little sick, get tested for coronavirus.

People infected with the coronavirus can spread it easily, even if they're not yet experiencing severe symptoms of the disease, according to virologists watching the pandemic unfold in Europe.

The fragile peace deal taking shape in Afghanistan could spell the end of an era of for the U.S. military, one marked by efforts at nation-building and winning hearts and minds.

It appears that the Pentagon is also intent on ending a research program from that era — to fund social science for the military.

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.
