To understand the universe, science calls on the ultrasmall
Will the universe expand outward for all of eternity and end in a vast, dark, cold, sterile, diffuse nothingness? Or will the "Big Bang" - the gargantuan explosion that formed the universe 14 billion years ago - end in the "Big Crunch?" view more (2009-08-17)
Astrophysicists Solve Mystery in Milky Way Galaxy
A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the universe. view more (2009-07-09)
Spallation Neutron Source sends first neutrons to 'Big Bang' beam line
New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies. view more (2008-10-10)

2,500 researchers, 1 supermachine, 1 new snapshot of the universe
Deep in the bowels of the earth -100 metres below ground in Geneva, Switzerland - lies a supermachine of 27 km circumference called the Large Hadron Collider (LHC) that has been built to unlock the mysteries of the universe. view more (2008-04-01)
Why matter matters in the universe
A new physics discovery explores why there is more matter than antimatter in the universe. view more (2008-03-31)
Were the first stars dark?
Perhaps the first stars in the newborn universe did not shine, but instead were invisible "dark stars" 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter, a University of Utah study concludes view more (2007-12-03)
Molecules of positronium observed in the laboratory for the first time
Physicists at UC Riverside have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of their antiparticles, called positrons. view more (2007-09-13)
Where has all the antimatter gone?
Scientists from the Universities of Liverpool and Glasgow have completed work on the inner heart of an experiment which seeks to find out what has happened to all the antimatter created at the start of the Universe. view more (2007-04-12)
Nobel laureate Burton Richter to speak about future of particle physics
Particle physics is about to transform our thinking once again. Experiments of the last 15 years suggest new forms of matter, new forces of nature and perhaps even new dimensions of space and time. Pinning down the new ideas will require more data from larger and more expensive machines-at a time when funding is more difficult than ever to secure. view more (2007-02-16)
UCR-led research team detects 'top quark,' a basic constituent of matter
A group of 50 international physicists, led by UC Riverside's Ann Heinson, has detected for the first time a subatomic particle, the top quark, produced without the simultaneous production of its antimatter partner - an extremely rare event. view more (2006-12-14)
Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed. view more (2006-11-28)
Big magnet ready to face the big questions of the universe
The largest superconducting magnet ever built has successfully been powered up to its operating conditions at the first attempt. Called the Barrel Toroid because of its shape, this magnet is a vital part of ATLAS, one of the major particle detectors being prepared to take data at CERN's Large Hadron Collider (LHC), the new particle accelerator... view more...

Antiprotons 4 times more effective than protons for cell irradiation
A pioneering experiment at CERN with potential future application in cancer therapy has produced its first results. Started in 2003, ACE (Antiproton Cell Experiment) is the first investigation of the biological effects of antiprotons. view more (2006-11-01)
It Might Be... It Could Be... It Is !
Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced today (September 25, 2006) that they have met the exacting standard to claim discovery of astonishingly rapid transitions between matter and antimatter: 3 trillion oscillations per second. view more (2006-09-26)
Physicists size up the 'unitarity triangle'
B factory experiments at the Stanford Linear Accelerator Center (SLAC) in the USA and at the High Energy Accelerator Research Organization (KEK) in Japan have reached a new milestone in the quest to understand the matter-antimatter imbalance in our universe. view more (2006-06-26)
Discovery Prospects at the Large Hadron Collider
Will scientists ever find the elusive Higgs particle, the last of the fundamental particles predicted by the Standard Model of particle physics and postulated to play a major role in how fundamental particles get their masses? view more (2006-04-25)
What Happened to the Antimatter? Fermilab's DZero Experiment Finds Clues in Quick-Change Meson
Scientists of the DZero collider detector collaboration at the Department of Energy's Fermi National Accelerator Laboratory have announced that their data on the properties of a subatomic particle, the B_s meson ("B sub s"), suggest that the particle oscillates between matter and antimatter in one of nature's fastest rapid-fire... view more...
