Mar 17, 2011 Trace radiation could reach West Coast
Some simulations now show traces of radiation from Japan potentially reaching across the Pacific to the U.S. West Coast by Friday, but even if it did, the radiation amounts would be so tiny that they would represent no health threat, experts say. "Our six-day forward plume simulation shows most...
Mar 04, 2011 Astronaut’s UCI talk ‘like coming home’
  Astronaut Tracy Caldwell Dyson makes an extraordinary return to UC Irvine Monday, when she’ll tell an audience at the Beckman Center what it was like to live for nearly six months in space. Caldwell Dyson, who conducted three complex and potentially hazardous spacewalks while on...
Feb 23, 2011 Dark Matter: New Evidence on How Galaxies Are Born
If you think it's hard to swallow the concept of dark matter, you're not alone. Decades ago, a few astronomers began to suspect that the universe was swarming with some mysterious, invisible substance that was yanking galaxies around with its own powerful gravity. And for those same decades, most...
Feb 18, 2011 Herschel Measures Dark Matter For Star-Forming Galaxies
The Herschel Space Observatory has revealed how much dark matter it takes to form a new galaxy bursting with stars. Herschel is a European Space Agency cornerstone mission supported with important NASA contributions. The findings are a key step in understanding how dark matter, an invisible...
Feb 17, 2011 Stellar recipe? UCI study says it's a dollop of dark matter
To make a young galaxy burst with stars, one mysterious ingredient is a must: dark matter, the invisible, so-far unidentified material that appears to form "haloes" around all galaxies, including our own. Scientists even know how much to add. The minimum solar mass is 300 billion suns," said...
Feb 16, 2011 Galaxy Size Matters … And This is Not a Rorschach Test
When it comes to forming stars, the size of a galaxy does matter, according to research out today in the online version of Nature. But it doesn’t have to be as massive as we once thought. Alexandre Amblard, an astrophysicist at the University of California, Irvine, and his colleagues used new...
Feb 11, 2011 Southwestern Water: Going, Going, Gone?
The glum projections of the growing gap between demand for water in the Southwest and the dwindling supplies have never been optimistic, but two new studies— one a research report based on satellite data, and the other an analysis of rainfall, water use and the costs associated with obtaining new...
Feb 11, 2011 UCI device probes ancient wine, climate
Deep in an Armenian cave, copper-age vintners pressed and fermented their grapes for what were likely solemn occasions: Their production room was part of a large cemetery complex. Four or five centuries later, someone lost a leather shoe near the entrance to the same group of caves shortly before...
Feb 10, 2011 Lettuce is sucking California's fruit basket dry
It may be a land of milk and honey, but California's Central valley - the most productive farmland in the US - is being sucked dry. The culprits? Lettuce and other green vegetables. James Famiglietti at the University of California, Irvine, used the twin GRACE satellites to find that 20 cubic...
