Geoff Brumfiel

Science correspondent Geoff Brumfiel's reports on physics, space, and all things nuclear can be heard across NPR News programs and on NPR.org.

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. He became a full-time correspondent in March of 2013.

Prior to NPR, Geoff 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.

Researchers have answered a question that has been nagging them for years: Exactly how long is a day on the planet Saturn? The result (10 hours and 32 minutes or so) was published this week in the journal Nature, and could teach scientists more about the giant, ringed planet.

A day is simply how long it takes a planet to spin all the way around. On Earth, one rotation takes 23 hours, 56 minutes and 4 seconds — though earthlings round up to 24 hours even.

Saturn's moon Enceladus is a mystery. From Earth it looks tiny and cold, and yet it's not a dead hunk of rock. Passing spacecraft see trenches and ridges, similar to Earth's, and in 2005 NASA's Cassini mission spotted ice geysers streaming from its south pole.

Scientists who warn that the earth's climate is changing have been subjected to hacking, investigations, and even court action in recent years. That ire usually comes from conservative groups and climate skeptics seeking to discredit the research findings.

This morning, a plucky NASA spacecraft has entered the orbit of one of the oddest little worlds in our solar system.

Ceres is round like a planet, but really small. Its total surface would cover just a third of the United States.

Gerbils are a beloved classroom pet, but they might also be deadly killers. A study now claims that gerbils helped bring bubonic plague to Medieval Europe and contributed to the deaths of millions.

Plague is caused by bacteria (Yersinia pestis) found in rodents, and the fleas that live on rodents. The rodent that's usually Suspect Zero is the rat.

The love between two ferns knows few bounds, it appears. A DNA analysis of a hybrid fern shows that its parents are two different species separated by nearly 60 million years of evolution.

"A 60 million year divergence is approximately equivalent to a human mating with a lemur," says Carl Rothfels, a fern researcher at the University of British Columbia, who headed the study. The hybrid is a record, he says.

Earlier this month the U.S. Navy's research office rented out a conference center in Washington, D.C., to show off some of its hottest new technology.

On display was an electromagnetic gun, and drones that could swarm around an enemy ship. But it wasn't all James Bond-style gadgets.

Researchers in Europe have managed to read from an ancient scroll buried when Mount Vesuvius erupted in 79 A.D. The feat is all the more remarkable because the scroll was never opened.

The Vesuvius eruption famously destroyed Pompeii. But it also devastated the nearby town of Herculaneum. A villa there contained a library stacked with papyrus scrolls, and the hot gas and ash preserved them.

Sort of.

The "Lone Genius" character is hot right now in television and movies. Sometimes the genius is real (think Benedict Cumberbatch in The Imitation Game), and sometimes he's fictional (think Benedict Cumberbatch in Sherlock). But one thing is almost always certain: He's a guy.

Now one researcher says that gender stereotype in art may have a real impact on women in academia.

Update at 6:46 a.m. ET. Launch Scrubbed:

Early on Tuesday, SpaceX scrubbed a scheduled launch, citing technical problems. The next possible attempt is Friday at 5:09 ET, NASA said.
