Ocean floor dust gives new insight into supernovae
Scientists plumbing the depths of the ocean have made a surprise finding that could change the way we understand supernovae, exploding stars way beyond our solar system.
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.
Sensitive detection method may help impede illicit nuclear trafficking
According to the International Atomic Energy Agency (IAEA) the greatest danger to nuclear security comes from terrorists acquiring sufficient quantities of plutonium or highly enriched uranium (HEU) to construct ...
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.
Britain to use spent nuclear fuel for batteries to power deep space craft
After 50 year search, research team finds plutonium signature
US science group says it's time to start burying plutonium
New study queries interactions of metal-reducing bacteria with plutonium oxide
(PhysOrg.com) -- Recent work by scientists at Pacific Northwest National Laboratory has shed new light on the perplexing environmental chemistry of plutonium. They demonstrated that under anaerobic, or oxygen-free, ...
Plutonium's unusual interactions with clay may minimize leakage of nuclear waste
As a first line of defense, steel barrels buried deep underground are designed to keep dangerous plutonium waste from seeping into the soil and surrounding bedrock, and, eventually, contaminating the groundwater. But after ...
New thermodynamic model predicts plutonium solubility with iron
A hard-to-detect but stable form of iron helps convert subsurface plutonium from barely to very soluble, according to scientists at Pacific Northwest National Laboratory and Rai Enviro-Chem, LLC. Plutonium ...
Plutonium tricks cells by 'pretending' to be iron
(PhysOrg.com) -- Plutonium gets taken up by our cells much as iron does, even though there's far less of it to go around.
Major report released by MIT: No shortage of uranium for nuclear energy, more research needed
Uranium supplies will not limit the expansion of nuclear power in the U.S. or around the world for the foreseeable future, according to a major new interdisciplinary study produced under the auspices of the MIT ...
Someday, a way to 'see' nuclear, chemical threats
Ordinarily, the small square of plastic and glass has a reddish color. But when Drexel University graduate student Sameet Shriyan flicks a switch, applying a bit of electricity, suddenly the red fades and the material becomes ...
Fuel for deep space exploration running on empty
(AP) -- NASA is running out of nuclear fuel needed for its deep space exploration.
