Making fuel for exploring space

Since its 1977 launch, NASA's Voyager 1 spacecraft has travelled farther than any other piece of human technology. It is also the only human-made object to have entered interstellar space.

Neutrons find 'missing' magnetism of plutonium

Groundbreaking work at two Department of Energy national laboratories has confirmed plutonium's magnetism, which scientists have long theorized but have never been able to experimentally observe. The advances that enabled ...

Probing what happens to plutonium in a nuclear explosion

For years, research on nuclear weapons has relied on old data, limited experiments and computer modeling. But this year, that pattern has changed. Scientists have run new experiments that simulate what happens to plutonium ...

Antineutrino detectors could aid non-proliferation

Physicists at the Large Hadron Collider in Switzerland and even in the fictional world of CBS' "The Big Bang Theory" look to subatomic particles called neutrinos to answer the big questions about the universe.

Radiation detected near New Mexico nuke site

Scientists who monitor the nation's only underground nuclear waste repository say they have detected radiation in the air a half-mile from the site.

N-test legacy in stratosphere bigger than thought

Levels of radioactive plutonium in Earth's stratosphere from nuclear tests and accidents is higher than previously thought, but probably not dangerous to humans, scientists in Switzerland said Tuesday.
