Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates. This could partially explain why wild populations of some pollinators, particularly bees -- which need nectar for food -- are declining in several areas of the world, including California and the Netherlands. "The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters; but in today's polluted environment downwind of major cites, they may travel only 200 to 300 meters," said Jose D. Fuentes, a professor of environmental sciences at the University of Virginia and a co-author of the study. "This makes it increasingly difficult for pollinators to locate the flowers."

A new, high- resolution, interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren't all where we thought. "For example, we've been attributing too many emissions to the northeastern United States, and it's looking like the southeastern U.S. is a much larger source than we had estimated previously," says Kevin Gurney, an assistant professor of earth and atmospheric science at Purdue University and leader of the project. The maps and system, called Vulcan, show CO2 emissions at more than 100 times more detail than was available before. Until now, data on carbon dioxide emissions were reported, in the best cases, monthly at the level of an entire state. The Vulcan model examines CO2 emissions at local levels on an hourly basis.

Today's consumers want tools to help them keep track of the energy they use. Products that measure the amount of energy you use, and have the ability to automatically adjust your appliances for maximum conservation, may soon be available for home use. "Consumers lower their energy bills and can get detailed reports on their usage trends, such as which devices in the home consume the most power. There are also significant benefits for the utility and the transmission grid. By dialing down consumption at peak times, utilities can avoid turning on costly--and typically very polluted--auxiliary power plants."
