Air pollution link to clogged arteries
07-25-2007 · EurekAlert!
Should we be watching our exposure to airborne pollution as well as our cholesterol levels? Research now indicates that air pollution has a role to play in atherosclerosis (artery hardening), which can contribute to heart attacks or strokes. Findings published in the open access journal, Genome Biology, show how the fats that clog arteries work together with air pollution particles, triggering the genes behind inflammation.

Linking air pollutants and blood clotting in mice
09-20-2007 · EurekAlert!
Air pollution is caused by any particulate matter, chemical or biological agent that changes the natural characteristics of the atmosphere. Exposure to particulate matter has been linked to an increased risk of heart problems, including increased risk of heart attack. A new study in mice has now identified a mechanism by which exposure to particulate matter leads to accelerated blood clotting and thrombosis, something that can precipitate heart attacks and stroke.

Car buyers who use the Internet spend less time at the dealership negotiating prices
06-04-2007 · EurekAlert!
In one of the first studies to detail how car purchasing has changed since the advent of the Internet, researchers find that online research has largely supplanted time spent at the dealership, time spent negotiating prices, and use of third-party sources such as Consumer Reports. The study, forthcoming in the June issue of the Journal of Consumer Research, also reveals that the overall time buyers spent searching for a car has increased with Internet research.

Gender may play role in recovery from pneumonia after ozone exposure
06-25-2007 · EurekAlert!
Does air pollution have a bigger effect on the immune system of females than males? It did among mice exposed to ozone -- a major component in air pollution that is known to negatively affect lung function -- and then infected with pneumonia, as significantly more females died from the infection than males.

Pollution shrinks fetus size: Brisbane study finds
01-06-2008 · EurekAlert!
Exposure to air pollution significantly reduces fetus size during pregnancy, according to a new study by Brisbane scientists. Queensland University of Technology senior research fellow Dr. Adrian Barnett said the study compared the fetus sizes of more than 15,000 ultrasound scans in Brisbane to air pollution levels within a 14km radius of the city.

University of Penn chemists reinvent the science and industry of making plastics
10-12-2006 · EurekAlert!
Chemists at the University of Pennsylvania have created a new process for free radical polymerization, the chemical reaction responsible for creating an enormous array of everyday plastic products, from Styrofoam cups to PVC tubing to car parts. Unlike the "traditional" method for living polymerization, which has been around for more than 50 years, this method takes place at room temperature, uses less metal catalyst to drive the reaction and requires a very short reaction time.

Why our shifty eyes don't drive us crazy
11-08-2006 · EurekAlert!
Our eyes are constantly making saccades, or little jumps. Yet the world appears to us as a smooth whole. Somehow, the brain's visual system "knows" where the eyes are about to move and is able to adjust for that movement. In a paper published online this week in Nature, researchers at the University of Pittsburgh and the National Eye Institute for the first time provide a circuit-level explanation as to why.
