First results from new detector reveal detailed properties of subatomic ‘soup’ that mimics the early universe

By teasing out signatures of particles just tenths of a millimeter from the center of a trillion-degree fireball that mimics the early universe, nuclear physicists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and from other sites are gaining new insights about fundamental physics. They achieved this by smashing together gold nuclei at the Relativistic Heavy Ion Collider (RHIC). (more…)

LONG BEACH, Calif.—Scientists working together on Kelp Watch 2014 announced today that the West Coast shoreline shows no signs of ocean-borne radiation from Japan’s Fukushima nuclear power plant disaster, following their analysis of the first collection of kelp samples along the western U.S. coastline.

Kelp Watch 2014 is a project that uses coastal kelp beds as detectors of radioactive seawater arriving from Fukushima via the North Pacific Current. It is a collaborative effort led by Steven Manley, marine biology professor at California State University, Long Beach (CSULB), and Kai Vetter, head of applied nuclear physics at the Lawrence Berkeley National Laboratory (Berkeley Lab) and a nuclear engineering professor at the University of California, Berkeley.

The long-sought Higgs boson—the particle that endows all elementary particles in the universe with mass—was elusive no longer when scientists at the CERN physics laboratory in Switzerland, discovered it last summer.

The July 4, 2012 announcement of the discovery appealed to both the general public and the media: Fifty-five media organizations and more than one billion television viewers made it an event that couldn’t be missed. Time even dubbed the Higgs boson “Particle of the Year.” (more…)

UW Deploying Seismic Sensors in Hope of Getting to Bottom of Spokane Quakes

It’s been a decade since a swarm of relatively mild earthquakes shook up parts of Spokane. Now, armed with the right tools, scientists want to find out what was at fault.

“It was always something not as well understood as we thought it should be,” said Douglas Gibbons, a University of Washington researcher in Earth and space sciences, who is guiding installation of strong-motion sensors as part of a project called NetQuakes.

NetQuakes will install a half-dozen seismometers in the Spokane area by the end of June, mostly in volunteers’ homes, to help improve understanding of what lies beneath the city. (more…)

Massive detector homes in on cosmic ray production

IceCube, an international collaboration involving University of Delaware scientists, is shedding new light on cosmic ray production.

Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is homing in on how the highest energy cosmic rays are produced. (more…)
