Local sources major cause of US near-ground aerosol pollution
11-16-2007 · EurekAlert!A new NASA study estimates that most ground-level particulate pollution in the US stems from regional sources in North America and only a small amount is brought to the country from other parts of the world.

- Aerosol pollution slows down winds and reduces rainfall
01-22-2007 · EurekAlert!
Near-surface winds provide a renewable source of clean energy and evaporate water, helping rain clouds to build up. But aerosolized particles created from vehicle exhaust and other contaminants can accumulate in the atmosphere and reduce the speed of winds closer to the Earth's surface, which results in less wind power available for wind-turbine electricity and also in reduced precipitation, according to a study by Stanford and NASA researchers.

- Global 'sunscreen' has likely thinned, report NASA scientists
03-15-2007 · EurekAlert!
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases -- sunlight blocked by dust, pollution and other aerosol particles -- appears to have lost ground.

- Bacteria from patient's dental plaque causes ventilator-associated pneumonia
03-23-2007 · EurekAlert!
Patients admitted to a hospital's intensive care unit already are seriously ill, so the last thing they need is a new infection. Unfortunately, statistics show that as many as 25 percent of all patients admitted to the ICU and placed on ventilators develop pneumonia, which can be fatal. Ironically, it turns out that the patient’s own dental plaque is a major source of germs that cause ventilator-associated pneumonia.

- Helium isotopes point to the best sources of geothermal energy
11-30-2007 · EurekAlert!
Unknown to most, the US has enough geothermal energy below its surface to supply three times the amount of energy that the US consumes annually. Up until this point no one has tapped this source because finding the geothermal hot spots is too expensive. Recently researchers discovered that surface indicators can predict if geothermal energy sources are below the ground -- now no more expensive drilling is required.

- Clinical simulation technology used to improve communication of medical teams
12-21-2006 · EurekAlert!
The Institute of Medicine estimates that medical errors are the eighth leading cause of death in the United States, and poor communication can be a major source of those errors. Now the Clinical Simulation Center at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis hopes to improve patient safety by using clinical simulators to find the source of miscommunications during medical treatments.

- Pointing a finger at the source of fecal bacteria
05-23-2007 · EurekAlert!
In order to halt the pollution of streams with fecal bacteria, researchers must first determine the source of the contamination. By using several methods to analyze water, scientists are able to narrow down potential sources of contamination.

- Novel strategies for healthy aging
03-31-2007 · EurekAlert!
Protein degradation is a major cause of ageing and can be the result of attacks on proteins by other molecules. One of these processes, glycation, involves the attack by sugars on proteins. Protection against glycation declines with age leading to increasing damage with increasing age. A critical enzyme involved in protection against glycation is "Glyoxalase 1." Scientists have shown for the first time that by enhancing levels of glyoxalase I the glycation process can be diminished and life can be extended by up to 40 percent.

- New VERITAS telescope array may help find 'dark matter'
04-30-2007 · EurekAlert!
Scientists in the Northern Hemisphere have opened a new window on the universe allowing them to explore and understand the cosmos at a much higher level of precision than was previously available. Think of it as acquiring a new pair of glasses that allow you to see more clearly. These new "glasses" are VERITAS, (the Very Energetic Radiation Imaging Telescope Array System), a major new ground-based gamma-ray observatory, designed to provide an in-depth examination of the universe.

- Avoiding sweets may spell a longer life, study in worms suggests
10-02-2007 · EurekAlert!
A new study in the October issue of Cell Metabolism, a publication of Cell Press, reveals that worms live to an older age when they are unable to process the simple sugar glucose. Glucose is a primary source of energy for the body, and can be found in all major dietary carbohydrates as a component of starches and other forms of sugar, including sucrose and lactose.
