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...

In a study published in the journal Nature Physics, researchers report trapping some 300 antihydrogen atoms for a record 16 minutes, a stunning technical feat that promises deeper insights into the mysteries of antimatter. Particles and anti-particles annihilate each other in a small flash of energy when they collide making the study of them extremely difficult. Fourteen-million years ago, at the moment of the big bang, matter and antimatter are believed to have existed in equal quantities....

If you have stayed up nights wondering about the shape of electrons, you can now sleep easier. Electrons have been found to be almost, but not quite, perfectly round, The Telegraph reports. Researchers at Imperial College London have recently measuremed the shape of the electron, finding that it is almost a perfect sphere, in a study published in the journal Nature. The decade-long experiment suggests that the electron differs from being perfectly round by less than...

AMSTERDAM, May 23, 2011 /PRNewswire/ -- Four days after the Endeavour launch the Alpha Magnetic Spectrometer (AMS-02) has been successfully installed on the International Space Station (ISS). The 6700 kg Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle physics detector designed to operate as an external module on the International Space Station. It will use the unique environment of space to study the universe and its origin by searching for antimatter and dark...

The antimatter equivalent of helium nuclei has been produced by an international team of physicists working with the Relativistic Heavy Ion Collider at the U.S. Department of Energy's Brookhaven National Laboratory in New York. Two University of California, Davis professors are members of the team. A paper describing their results is published online this week by the journal Nature. "This is the heaviest antimatter anyone has ever created," said Manuel Calderon de la Barca Sanchez, professor...

Time-of-flight detector designed at Rice's Bonner Lab critical to antihelium observation Physicists at Rice University and their collaborators have detected the antimatter partner of the helium nucleus, antihelium-4. This newly observed particle is the heaviest antimatter particle ever detected. Scientists at Rice's Bonner Lab designed and built the new time-of-flight detector that identified antihelium-4. The $7.5 million detector was built by a U.S.-China collaboration led by Rice, with...

Berkeley Lab nuclear scientists join with their international colleagues in the latest record-breaking discovery at RHIC Eighteen examples of the heaviest antiparticle ever found, the nucleus of antihelium-4, have been made in the STAR experiment at RHIC, the Relativistic Heavy Ion Collider at the U.S. Department of Energy's Brookhaven National Laboratory. "The STAR experiment is uniquely capable of finding antihelium-4," says the STAR experiment's spokesperson, Nu Xu, of the Nuclear Science...

Once regarded as the stuff of science fiction, antimatter"”the mirror image of the ordinary matter in our observable universe"”is now the focus of laboratory studies around the world. While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Once antimatter comes into contact with ordinary matter it "annihilates""”or disappears in a flash of gamma...

NASA scientists have discovered beams of antimatter being produced by thunderstorms here on Earth--a phenomenon that had never been observed before, the US space agency said on Monday. It is believed that the antimatter particles were formed in a terrestrial gamma-ray flash, or TGF. According to a NASA press release, about 500 of these lightning-related events occur each day, but most of them are undetected. This one was spotted using NASA's Fermi Gamma-ray Space Telescope. "These signals are...

WASHINGTON, Jan. 10, 2011 /PRNewswire-USNewswire/ -- Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists think the antimatter particles were formed in a terrestrial gamma-ray flash (TGF), a brief burst produced inside thunderstorms and shown to be associated with lightning. It is estimated that about 500 TGFs...
