They were always mysterious. 26 years had to pass before the prediction of theoretical physics was confirmed and the existence of neutrinos was finally proven experimentally in 1956. The reason for this ordeal: Neutrinos only interact by the weak interaction with other particles of matter. When a cosmic neutrino approaches the earth, it has the best chance of passing through the whole globe unhindered. It is correspondingly difficult to find direct evidence of neutrinos with the help of a...

A new Chinese experiment could help explain why matter predominates over antimatter in the universe. The Daya Bay experiment aims to explain the mystery by using antineutrinos as a probe to measure a crucial type of transformation called neutrino mixing. "Right now there is not a good understanding of what causes the matter-antimatter imbalance in the universe," Karsten Heeger, a University of Wisconsin"“Madison physics professor and one of the leading scientists in the experiment,...

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...

The results of a high-profile Fermilab physics experiment involving a University of Michigan professor appear to confirm strange 20-year-old findings that poke holes in the standard model, suggesting the existence of a new elementary particle: a fourth flavor of neutrino. The new results go further to describe a violation of a fundamental symmetry of the universe asserting that particles of antimatter behave in the same way as their matter counterparts. Neutrinos are neutral elementary...

When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics. It's a mystery that presented itself unexpectedly: The radioactive decay of some elements sitting quietly in laboratories on Earth seemed to be influenced by activities inside the sun, 93 million miles...

Neutrinos are likely half as massive as previous estimates suggested Physicists have long known that neutrinos are among the lightest and most evasive fundamental particles. Now a survey of the galaxies is helping to narrow down the neutrino mass even further. It seems that neutrinos are at best half as massive as previously estimated, according to an analysis appearing today in the journal Physical Review Letters. The lower neutrino mass estimate is the result of a 3-dimensional survey of...

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...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
