Managing manure in California
December 12, 2007 05:32 PM - Alec Rosenberg, UC Merced Newswire

 

Merced, California -  A partnership between agricultural leaders and UC Merced aims to help California farmers maintain the environment and the economy.

California is the nation's leading dairy state, generating $5.2 billion in milk and cream sales a year. While that keeps the state's 1.7 million dairy cows busy making milk, they also produce plenty of manure. The manure is filled with nutrients that farmers can use as fertilizer, but it also can pollute the environment.

Chemicals used as fire retardants could be harmful
December 12, 2007 05:02 PM - UC Riverside, Newswire

Riverside, California - Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa. Now, as reported in a news story days ago, they are being found in alarming concentrations, in human blood and breast milk – a potentially major concern for human health.

Berkeley, California -- Five satellites launched last February to probe magnetic storms around the Earth will move into prime observing position next month, but they already have produced important new information on the interactions between the solar wind and the Earth's magnetic field.

Cholesterol drugs may raise brain hemorrhage risk
December 12, 2007 04:33 PM - Reuters

NEW YORK (Reuters Health) - The use of cholesterol-lowering "statin" drugs, such as Lipitor (atorvastatin) and Zocor (simvastatin), may raise the risk of brain hemorrhage in patients who have experienced a recent stroke or a transient ischemic attack (TIA), new research suggests. Still, this risk may be outweighed by the ability of these agents to lower the overall risk of a second stroke and other serious events, such as heart attack.

CALGARY, Alberta (Reuters) - A tiny oil-eating bug that lives deep underground may allow the world's oil industry to unlock energy trapped in trillions of barrels of heavy crude, which is costly and dirty to produce using today's methods.

Fuel cells help make noisy, hot generators a thing of the past
December 12, 2007 09:06 AM - DOE/Pacific Northwest National Laboratory

Two core technologies developed at the Department of Energy's Pacific Northwest National Laboratory - a fuel desulfurization system and a fuel reforming system - were instrumental in the demonstration of an electric power system operating on JP-8, a fuel commonly used in military operations.

Portable fuel cell power units are quieter, more efficient and have lower emissions than standard diesel generators, but are challenged when used with JP-8 fuel because of its sulfur content. The fuel desulfurization and reforming systems developed at PNNL reduce the sulfur content of JP-8 and generate a hydrogen stream compatible with an integrated fuel cell.
