Pamela Fleming, spokesperson of The Institute for Basic Research, Palm Harbor, Florida, has released an open letter to the Directors of Cern laboratories in Geneva, Switzerland, containing unchallenged technical arguments showing that their ongoing test of the gravity of antimatter via alleged "anti-Hydrogen atoms" may be basically flawed, and requesting due scientific process on alternative more resolutory tests (http://www.i-b-r.org/G-Veneziano-denunciation.htm). New York,...

Antimatter Method Could Provide Major Experimental Advantage
2013-01-07 07:27:31

redOrbit Staff & Wire Reports - Your Universe Online By aiming a laser at antihydrogen atoms, researchers have found that they can force them to lose energy and plummet to temperatures 25-times colder than previously achieved -- a discovery which could greatly assist the study of the more elusive properties of antimatter. The method, which was developed by a team of experts from the US and Canada, is described in the most recent edition of the Journal of Physics B: Atomic, Molecular...

Microwaves Used In First Time Measurement Of Antimatter Atom
2012-03-08 05:43:30

An international team of physicists at CERN (the European Laboratory for Particle Physics) used microwaves to measure and manipulate an atom made of antimatter for the first time ever. While imprecise, the measurement represents an important first step in being able to study antimatter atoms in detail --  a critical part of understanding why the universe is made of matter and not antimatter. "This is the first time that anyone has ever interacted with an antimatter atom," said lead...

Tevatron Program To Close Down On Friday
2011-09-29 13:46:23

The Fermi National Accelerator Laboratory's Tevatron particle accelerator is set to retire on Friday, ending its 25 year career in an Illinois prairie. The Tevatron has been outranked by the more powerful atom smasher Large Hadron Collider, built by the European Center for Nuclear Research (CERN). U.S. physicists will now have to work with CERN on high-energy projects instead of pursuing the research on their own turf. The American particle accelerator failed to raise enough funds to...

For the first time, researchers have confirmed the existence of antimatter in the Earth's magnetosphere, BBC News reported on Sunday. Writing in Astrophysical Journal Letters, the researchers report that they discovered a thin band of antiprotons lying in between the inner and outer Van Allen radiation belts using the PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) satellite. Though the British news organization claims that only a small number of antiprotons...

Most important milestone in the direct measurement of the magnetic moment of the proton and its anti-particle has been achieved / Focusing the matter-antimatter symmetry Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidelberg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, have observed spin quantum-jumps with a single trapped proton for...

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....

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...

Word of the Day
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
