Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator Laboratory announced today (June 24) the results from a search for a rare phenomenon, the transformation of muon neutrinos into electron neutrinos. The result is consistent with and significantly constrains a measurement reported 10 days ago by the Japanese T2K experiment, which announced an indication of this type of transformation. The results of these two experiments could have implications for our...

An international research team led by Japan and that includes the University of Colorado Boulder may have taken a significant step in discovering why matter trumped antimatter at the time of Big Bang, helping to create virtually all of the galaxies and stars in the universe. The experiment, known as the Tokai to Kamioka experiment, or T2K, included shooting a beam of neutrinos underground from the Japan Proton Accelerator Research Complex, or J-PARC, on the country's east coast to a detector...

Researchers from Queen Mary, University of London (UK) and the University of Fribourg (Switzerland) have shown that a magnetically polarised current can be manipulated by electric fields. Published this week in the journal Nature Materials, this important discovery opens up the prospect of simultaneously processing and storing data on electrons held in the molecular structure of computer chips - combining computer memory and processing power on the same chip. "This is especially exciting, as...

An international team measures the charge radius of the hydrogen nucleus and stumbles across some mysteries of physics Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimeter. This is precisely the difference between the new, smaller, dimension of the proton, the nucleus of the hydrogen atom, and the value which has been assumed so far. Instead of 0.8768 femtometers it measures...

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...

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...

Researchers have unearthed a magnetic force similar to electricity: magnetic charges that act and interrelate like electrical charges. This is the first known use of the magnetic monopoles that subsist in spin ice crystals. A research team wrote that monopoles have the ability to group together and form a "magnetic current" similar to electricity. Called "magnetricity", this new discovery may be utilized in magnetic storage or computers. Magnetic monopoles were first thought to be present a...

True muonium, a long-theorized but never-seen atom, might be observed in future experiments, thanks to recent theoretical work by researchers at the Department of Energy's SLAC National Accelerator Laboratory and Arizona State University. True muonium was first theorized more than 50 years ago, but until now no one had uncovered an unambiguous method by which it could be created and observed. "We don't usually work in this area, but one day we were idly talking about how experimentalists...

Cosmic-rays detected half a mile underground in a disused U.S. iron-mine can be used to detect major weather events occurring 20 miles up in the Earth's upper atmosphere, a new study has revealed. Published in the journal Geophysical Research Letters and led by scientists from the UK's National Centre for Atmospheric Science (NCAS) and the Science and Technology Facilities Council (STFC), this remarkable study shows how the number of high-energy cosmic-rays reaching a detector deep...
