A study combines experimental observations of spider webs with complex computer simulations has shown that web durability depends not only on silk strength, but on how the overall web design compensates for damage and the response of individual strands to continuously varying stresses.
Research into biofuel crops, such as switchgrass and Miscanthus, has focused mainly on how to grow these crops and convert them into fuels. But many steps lead from the farm to the biorefinery, and each could help or hinder the growth of this new industry.
Robotic exploration to remote regions, to include distant planetary bodies, is often limited by energy requirements to perform, in repetition, even the simplest tasks.
Researchers at Aalto University in Finland have developed a new and significantly cheaper method of manufacturing fuel cells.
Engineering researchers at the University of Arkansas are developing an anti-icing system that could make airport runways safer and less expensive to maintain during winter months.
Explaining the purchase of a hundred pounds of dry ice to the authorities might be a bit awkward for some people; however, for Ari Jumpponen, associate professor of biology at Kansas State University, it's just another day as a scientist.
Emissions regulations do have an environmental impact, according to a long-term study of acidic rainfall by researchers at the University of Illinois at Urbana-Champaign.
The rapid, large scale coastal development underway in the Middle East must be better planned and managed to avoid aggravating degradation and losses in the fragile marine ecosystems shared by eight Gulf countries – Bahrain, Kuwait, Iran, Iraq, Oman, Qatar, Saudi Arabia, and the United Arab Emirates – warns a new report by the United Nations University (UNU).
A new report by Duke University researchers offers several health and environmental measures for North Carolina lawmakers to consider as they debate legalizing horizontal drilling and hydraulic fracturing for natural gas.
Technology with the ability to detect more than 1,000 colors, the hyperspectral camera is being used to diagnose contaminants and other environmental hazards in real time.
Researchers are now developing a solar panel composed of nano-antennas instead of semiconductors.
Officials from the U.S. Environmental Protection Agency (EPA) and the U.S. General Services Administration (GSA) toured e-Green Management of Islip Terrace, New York to highlight the environmental, public health and economic benefits of recycling electronics.
NOAA's updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend that began with the Industrial Revolution of the 1880s.
Pipe-in-pipe systems are now commonly used to distribute water in many homes. The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). Are these pipes harmful to health and do they affect the taste and odour of drinking water?
During the summer 2003, high temperatures and drought conditions in Europe led to a reduction of the wind force with direct consequences on the wind energy power, reduced by 22 percent. The study was recently published in Journal of Climate.
A team of Virginia Tech researchers is working to characterize the genes involved in wood formation in poplar trees with the goal of improving the quality and quantity of wood as a feedstock for biofuels production.
Both climate change and humans were responsible for the extinction of some large mammals, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals.
Plain, sloping roofs can collect up to 50 percent more rainwater than flat roofs with gravel.
Pesticides and pollutants are related to an alarming 450 percent increase in the risk of spina bifida and anencephaly in rural China, according to scientists at The University of Texas at Austin and Peking University.
A University of Minnesota team of researchers has overcome a major hurdle in the quest to design a specialized type of molecular sieve that could make the production of gasoline, plastics and various chemicals more cost effective and energy efficient.
