Physicists working at the European Organization for Nuclear Research (CERN) announced on Wednesday that they had successfully trapped and stored antimatter atoms for the first time ever. Scientists from the Geneva, Switzerland-based research organization, in association with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley, trapped a substance known as antihydrogen--the antimatter equivalent of hydrogen. The international...

Discovery may challenge physics fundamentals In the movie Angels and Demons, scientists have solved one of the most perplexing scientific problems: the capture and storage of antimatter. In real life, trapping atomic antimatter has never been accomplished, until now. A team made up of researchers from the University of Calgary, institutions across Canada and around the world have discovered how to trap atomic antimatter and the results of their discovery is published in the journal Nature....

The Alpha Magnetic Spectrometer-2 (AMS) destined for the International Space Station already is collecting cosmic ray signatures, even as it sits in a work stand at the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, said Prof. Samuel Ting, the principal investigator for the program. It "Ëœs not making any grand discoveries yet, since the particles it is picking up were stripped of some of their qualities when they passed through Earth's atmosphere. But...

One of the most complex space scientific instruments ever built, the Alpha Magnetic Spectrometer (AMS-02) arrived at the Kennedy Space Center in Florida on Friday, escorted by astronauts who will fly with it on the Space Shuttle in February 2011. The antimatter hunter AMS-02 began the first stage of its voyage to the International Space Station (ISS) from Geneva international airport, in Switzerland. During a ceremony organized by the European Organisation for Nuclear Research (CERN), the...

A massive particle detector that will search the reaches of outer space for antimatter and other clues about the origins of the universe began the initial steps towards its voyage to the International Space Station on Wednesday. The European Organization for Nuclear Research (CERN) loaded the $2 billion Alpha Magnetic Spectrometer onto a giant C5 Galaxy U.S. Air Force transport plane at the Geneva airport, which will take off Thursday for Kennedy Space Center in Florida. "The AMS left the...

The Alpha Magnetic Spectrometer (AMS), an experiment that will search for antimatter and dark matter in space, leaves CERN next Tuesday on the next leg of its journey to the International Space Station. The AMS detector  is being transported from CERN to Geneva International Airport in preparation for its planned departure from Switzerland on August 26, when it will be flown to the Kennedy Space Center in Florida on board a US Air Force Galaxy transport aircraft.A press conference to...

Surprisingly large matter/antimatter asymmetry discovered in Fermilab experiments A large collaboration of physicists working at the Fermilab Tevatron particle collider has discovered evidence of an explanation for the prevalence of matter over antimatter in the universe. They found that colliding protons in their experiment produced short-lived B meson particles that almost immediately broke down into debris that included slightly more matter than antimatter. The two types of matter...

UC Riverside physicists involved in the international research; new result brings us closer to understanding the universe and its origins Why is there matter in the universe and not antimatter, its opposite? Physicists at Fermi National Accelerator Laboratory, including John Ellison, a professor of physics at UC Riverside, have announced that they have found evidence for a significant violation of matter-antimatter symmetry in decays of B-mesons, which are exotic particles produced in high...

Physicists at Fermilab have discovered a clue as to why the world around us is composed of normal matter and not anti-matter. Today, anti-matter is rare, but it can be produced by atom smashers, in nuclear reactions, or by cosmic rays. However, physicists believe the Big Bang should have produced equal amounts of matter and its opposite. The DZero experiment at Fermilab in Illinois has now produced results that provide a clue as to what happened to all the anti-matter. Many...

Researchers isolate collection of "pure" or spin polarized positronium atoms for the first time Positronium is a short-lived system in which an electron and its anti-particle are bound together. In 2007, physicists at the University of California, Riverside created molecular positronium, a brand-new substance, in the laboratory. Now they have succeeded in isolating for the first time a sample of spin polarized positronium atoms. Study results appear this week in the journal Physical Review...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
