Biocapture surfaces produced for study of brain chemistry
December 13, 2007 12:24 PM - Penn State

A research team at Penn State has developed a novel method for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules. By varying the identity and spacing of the tethered molecules, researchers can make the technique applicable to a wide range of bait molecules including drugs, chemical warfare agents, and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain.

PASADENA, Calif. --Studies of the snap judgments we often make about people are shedding new light not only on social behavior, but also on drug abuse, gambling addiction, and other disorders in which our ability to make decisions is impaired, say scientists at the California Institute of Technology.

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.
