Duke and Brookhaven examine free-flowing 'exploding cigars' Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar properties in a very hot and dense plasma "fluid" created to simulate conditions when the universe was about one millionths of a second old. The plasma was formed at a colossal 2 million degrees Kelvin temperatures within Brookhaven's...

The potential for the world's largest atom smasher to destroy Earth is one question weighing on the minds of some lay people as the Large Hadron Collider (LHC) prepares to go online Wednesday. Don't worry, say the experts, who are more concerned with whether the 17 mile-long particle accelerator underground at CERN, the European Organization for Nuclear Research near Geneva, Switzerland, will work as planned and, perhaps, reveal the existence of the so-called God particle. All...

A new report published on Friday, 5 September, provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on Wednesday this week, poses no threat to mankind. Nature's own cosmic rays regularly produce more powerful particle collisions than those planned within the LHC, which will enable nature's laws to be studied in controlled experiments. The LHC Safety Assessment Group have reviewed and updated a study first completed in 2003, which...

A report has concluded that the world's most powerful particle physics experiment is not putting our planet at risk. Critics are concerned that the Earth's very existence could be threatened by the mini-black holes created at the Large Hadron Collider facility on the French-Swiss border. A report from the European Organization for Nuclear Research says there is "no conceivable danger". The organization, also known as Cern, will operate the underground collider in a 27km-long tunnel near...

Accelerator physicists correct beam scattering, increase collision rates of speeding particlesImagine trying to catch up to something moving close to the speed of light - the fastest anything can move - and sending ahead information in time to make mid-path flight corrections. Impossible? Not quite. Physicists at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at the U.S. Department of Energy's Brookhaven National Laboratory, have achieved this tricky task - and the results...

British poet William Blake once wrote that a world was contained in a grain of sand. Physicists have done one better, finding a surprising link between streams of flowing sand grains and the birth of the universe. A new study in the latest issue of the journal Physical Review Letters finds that flowing sand grains show liquid-like behavior also witnessed in particle-collider experiments that simulate our universe's first moments. "Nature plays the tricks that it...

WASHINGTON -- Defense and space projects account for most increases in the $135 billion federal research and development budget next year, worrying scientists who fear that after years of growth the nation is beginning to skimp on technology that fuels marketplace innovation. The realignment by Congress of research money toward national defense and human space exploration means many universities, institutions and scientists will have to scramble for new sources of money or cut back current...

Using high-speed collisions between gold atoms, scientists think they have re-created one of the most mysterious forms of matter in the universe -- quark-gluon plasma. This form of matter was present during the first microsecond of the Big Bang and may still exist at the cores of dense, distant stars. UC Davis physics professor Daniel Cebra is one of 543 collaborators on the research. His main role was building the electronic listening devices that collect information about the collisions, a...

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. Not just any old liquid, either. Its collective movement is rather like the way a school of fish swims 'as one' and is a sign that the fluid...
