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...

Physicists create a 'perfect' way to study the Big Bang
Physicists have created the state of matter thought to have filled the Universe just a few microseconds after the big bang and found it to be different from what they were expecting. Instead of a gas, it is more like a liquid. Understanding why it is a liquid should take physicists a step closer to explaining the earliest moments of our Universe. view more (2005-07-21)
After the Big Bang: Project Explores Seconds that Shaped the Universe
Kent State faculty and graduate students are among a team of physicists who recreated the material essence of the universe as it would have been mere microseconds after the Big Bang—a quark-gluon plasma. view more (2006-07-13)
Physicist: Stars can be strange
According to the "Strange Matter Hypothesis," which gained popularity in the paranormal 1980's, nuclear matter, too, can be strange. view more (2006-12-19)
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)
Ultracold test produces long-sought quantum mix
In the bizarre and rule-bound world of quantum physics, every tiny spec of matter has something called "spin"-an intrinsic trait like eye color-that cannot be changed and which dictates, very specifically, what other bits of matter the spec can share quantum space with. view more (2005-12-23)
A new particle discovered by BaBar experiment
Its name is Y(4260) and it is not a new humanoid of Stars Wars, but a particle identified for the first time by BaBar experiment: an international collaboration-formed by the large participation of the Italian physicists of the National Institute for Nuclear Physics (Infn)-that has its seat in Stanford (California). Y(4260) represents an... view more... (2005-07-07)
G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration,... view more... (2006-06-30)
Supercomputers help physicists understand a force of nature
What if the tiniest components of matter were somehow different from the way they exist now, perhaps only slightly different or maybe a lot? What if they had been different from the moment the universe began in the big bang? Would matter as we know it be the same? Would humans even exist? view more (2006-07-12)
G-Zero Finds that Ghostly Strange Quarks Influence Proton Structure
In research performed at the Department of Energy's Jefferson Lab, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. view more (2005-06-20)
JHU-led team discovers exotic relatives of protons and neutrons
A team of scientists, including four at The Johns Hopkins University, has discovered two new subatomic particles, rare but important relatives of the familiar, commonplace proton and neutron. view more (2006-11-17)
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)
DZero finds evidence of rare single top quark; Observation marks a step closer to finding Higgs boson
Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced in a seminar at Fermilab on December 8, 2006 the first evidence of single top quarks produced in a rare subatomic process involving the weak nuclear force. view more (2006-12-18)
CDF precision measurement of W-boson mass suggests a lighter Higgs particle
Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced today (January 8, 2007) the world's most precise measurement by a single experiment of the mass of the W boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces. The new W-mass... view more... (2007-01-09)
XMM-Newton and Suzaku help pioneer method for probing exotic matter
Astronomers using XMM-Newton and Suzaku have seen Einstein's predicted distortion of space-time and pioneered a ground-breaking technique for determining the properties of neutron stars. view more (2007-08-28)
Undergraduate Helps Discover Beautiful Quark Combinations
University of Rochester physics undergraduate Scott Field participated in the search for two subatomic particles whose existence was announced today by scientists at the Fermi National Accelerator Laboratory (Fermilab) in Illinois. Field's research focused on the extremely rare quark of the "bottom" or "beauty" variety. view more (2006-10-24)

Physicists see similarities in stream of sand grains, exotic plasma at birth of universe
Streams of granular particles bouncing off a target in a simple tabletop experiment produce liquid-like behavior also witnessed in a massive research apparatus that simulates the birth of the universe. view more (2007-11-07)
