Scientists have made their most accurate measurement yet of the "ghost particles" known as neutrinos, according to a recent BBC report. Neutrinos are called ghost particles because they interact so weakly with other forms of matter. Previous experiments show that neutrinos have a mass, but it was so tiny it was unable to be measured. Researchers used data from the largest every survey of galaxies and put the mass of a neutrino at no greater than 0.28 electron volts. The scientists say...

An international team including scientists from Princeton University has detected subatomic particles deep within the Earth's interior. The discovery could help geologists understand how reactions taking place in the planet's interior affect events on the surface such as earthquakes and volcanoes. Someday, scientists may know enough about the sources and flow of heat in the Earth to predict events like the recent volcanic eruption in Iceland. The finding, made by the Borexino Collaboration at...

Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator laboratory today (June 14) announced the world's most precise measurement to date of the parameters that govern antineutrino oscillations, the back-and-forth transformations of antineutrinos from one type to another. This result provides information about the difference in mass between different antineutrino types. The measurement showed an unexpected variance in the values for neutrinos and...

On Monday, scientists in Europe said they have solved the case of the missing neutrinos, one of the enduring mysteries in the subatomic universe of particle physics. The researchers said the findings challenge core precepts of the so-called Standard Model of physics, and could have major implications for our understanding of matter in the universe. Neutrinos are electrically neutral particles that travel close to the speed of light. Physicists had observed for years that fewer neutrinos...

International collaboration hunting oscillation of muon to electron Physicists may see data as soon as late summer from the prototype for a $278 million science experiment in northern Minnesota that is being designed to find clues to some fundamental mysteries of the universe. But it could take years before the nation's largest "neutrino" detector answers the profound questions that matter to scientists. Construction is underway now on a 220-ton detector that is the "integration prototype"...

South Dakota Gov. Mike Rounds paid a visit to UC Berkeley and Berkeley Lab last Friday (June 12) to get a feel for the type of research operation the campus and the lab plan to build at his state's famed Homestake gold mine.Rounds has strongly supported efforts to turn the mine, founded in 1877 by mining magnate and California Sen. George Hearst and taken out of operation in 2002, into the world's premier underground research laboratory, and the only one capable of answering critical...

The IceCube Neutrino Observatory is a neutrino telescope that is currently being built at the Amundsen-Scott South Pole Station. IceCube is being constructed in deep Antarctic ice by deploying thousands of PMTs (photomultiplier tubes) at depths of 4750 to 8000 feet. These spherical optical sensors are deployed on strings of sixty modules each, into holes melted by hot water drilling. Since 2005, 59 strings have been deployed and installation is expected to be complete by 2011. The strings are...
