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.
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 project is slated to be the first plant in the United States to produce GTL transportation fuels and other products.

The state-of-the-art biomass gasification system will provide clean, carbon-neutral heat and power to the medical center.
Hurricane Irene and heavy rains across the East Coast have caused major flooding. Here are a few tips on what to do if your house meets with some of the floodwaters.
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.
The new UNTHA Recycling Technology (URT) system at the Appliance Recycling Centers of America (ARCA)’s facility in Philadelphia is ready to begin recycling as many as 150,000 refrigerators annually, GE and ARCA announced Sept. 9.
Legend tells of Greek engineer and inventor Archimedes using parabolic mirrors to create "heat rays" to burn the ships attacking Syracuse. Though the underpinnings of that claim are speculative at best, a modern-day team of researchers at the Scientific and Production Association in Uzbekistan has proposed a more scientifically sound method of harnessing parabolic mirrors to drive solar-powered lasers.
BUSolutions LCO-140H to revitalize urban transit by increasing fuel economy by 110 percent and reducing 12-year fleet operations cost by $50 million for the average sized transit authority.
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.
How can legislation be used to avoid hazardous waste being dumped where it could poison people and the environment in developing countries? Introducing producer responsibility could be one solution, says Panate Manomaivibool of the International Institute for Industrial Environmental Economics (IIIEE) at Lund University, Sweden, in a new thesis.
University of Iowa researchers have found high levels of toxic polychlorinated biphenyls (PCBs) in the deep sediments lining the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind.
The U.S. Environmental Protection Agency is proposing to approve the 8-hour ozone air quality plans for the San Joaquin Valley and South Coast areas. These plans, known as State Implementation Plans, are the roadmaps to meeting the Clean Air Act standard of 0.08 parts per million of ozone as measured in 8-hour increments.
The Florida Fish and Wildlife Conservation Commission recently partnered with Fishing for Energy to remove derelict stone crab traps from the marine environment near Everglades City, Fla., making it the second location in Florida to join the unique partnership.
