From funding smart meters on college campuses, to reducing hazardous chemicals in high school laboratories, to promoting alternatives to dry cleaning, the U.S. Environmental Protection Agency (EPA) is making its pollution prevention grants count across New Jersey and New York. The EPA has awarded more than $600,000 in grants to fund projects that help prevent pollution in these two states.
The Department of Transportation is proposing to explicitly ban the use of electronic cigarettes on aircraft.
A team of students from Embry-Riddle Aeronautical University demonstrated a first in aviation history.
The list highlights vulnerable elements where global production is concentrated in a small number of countries, including metals that are critical to development of a low-carbon digital economy. The list helps to focus future research on diversifying supply from new resources, using greener production technologies and cost-effective recycling.
Scientists have long debated about the impact on global climate of water evaporated from vegetation. New research from Carnegie's Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere.
The project is slated to be the first plant in the United States to produce GTL transportation fuels and other products.

They expressed concerns ranging from safety, such as unpredictable weather patterns and dangerous ice conditions, to changes in plants and animals as well as decreased availability of firewood.
Stanford researchers have gotten a glimpse into an uncertain future where increasing levels of carbon dioxide in the Earth's atmosphere will lead to higher levels in the ocean as well, leaving the water more acidic and altering underwater ecosystems.
The state-of-the-art biomass gasification system will provide clean, carbon-neutral heat and power to the medical center.
It seems fuel economy is on everyone's minds these days. The Metropolitan Transit Authority of Harris County, with its large bus fleet, is no exception.
La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter.
