Fire in enclosed military environments such as ship holds, aircraft cockpits and ground vehicles is a major cause of material destruction and jeopardizes the lives of warfighters. For example, a shipboard fire on the aircraft carrier USS George Washington in May 2008 burned for 12 hours and caused an estimated $70 million in damage. For nearly 50 years, despite the severity of the threat from fire, no new methods for extinguishing or manipulating fire were developed.

Wolverines live in harsh conditions; they range over large areas of cold mountainous low-productivity habitat with persistent snow. The paper suggests wolverines take advantage of the crevices and boulders of the mountainous terrain, as well as the snow cover to cache and "refrigerate" food sources such as elk, caribou, moose and mountain goat carrion, ground squirrels and other food collected during more plentiful times of year. These cold, structured chambers provide protection of the food supply from scavengers, insects and bacteria.
HOUSTON – (July 12, 2012) – New research at Rice University that seeks to establish points of reference between plasmonic particles and polymers might lead to smaller computer chips, better antennae and improvements in optical computing.
Materials scientists take advantage of strong interactions between chemicals to form polymers that self-assemble into patterns and are the basis of things people use every day. Anything made of plastic is a good example.
WASHINGTON, July 11, 2012 — The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes a new, inexpensive paper-based device designed for diabetes testing in rural areas of developing countries.
New Orleans, 11 July 2012— With the conclusion of a successful meeting of the Council of the Commission for Environmental Cooperation (CEC) on Community and Ecosystem Resilience in North America, North America's environment ministers Administrator Jackson, Minister Kent and Secretary Elvira, announced the modernization of the Submission on Enforcement Matters Process, a strengthened commitment to initiatives to Green the North American Economy, and a continued focus on streamlining the cooperative work program of the CEC.
The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models.
The process, named 'saddle-collapse', was found to be the cause of two rapid sea level rise events: the Meltwater pulse 1a (MWP1a) around 14,600 years ago and the '8,200 year' event. The research is published today in Nature.
Increasing the number of students interested in science, technology, engineering, and math – otherwise known as the STEM disciplines – is considered to be vital to national competitiveness in the global economy and to the development of a strong 21st century workforce. But the pipeline leading toward STEM careers begins leaking in high school, when students choose not to take advanced courses in science and math.
"Cows are happy in parts of Northern California and not in Florida" is a good way to sum up the findings of new research from the University of Washington, said Yoram Bauman, best known as the "stand-up economist."
Bauman and colleagues found that the decline in milk production due to climate change will vary across the U.S., since there are significant differences in humidity and how much the temperature swings between night and day across the country. For instance, the humidity and hot nights make the Southeast the most unfriendly place in the country for dairy cows.
Insecticide resistance is threatening the effectiveness of insecticide-treated bed nets and indoor insecticide sprays to control adult mosquito vectors, and so more sustainable integrated management strategies that use optimal suites of control tactics are needed. These are the arguments of Willem Takken from the Wageningen University and Research Centre in The Netherlands and colleagues in this week's PLoS Medicine.
COLUMBIA, Mo. -- Computer networks are the battlefields in cyberwarfare, as exemplified by the United States' recent use of computer viruses to attack Iran's nuclear program. A computer model developed at the University of Missouri could help military strategists devise the most damaging cyber attacks as well as guard America's critical infrastructure. The model also could benefit other projects involving interconnected groups, such as restoring ecosystems, halting disease epidemics and stopping smugglers.
Promising news for those who relish the prospects of a one-inch chip storing multiple terabytes of data, some clarity has been brought to the here-to-fore confusing physics of ferroelectric nanomaterials. A multi-institutional team of researchers, led by scientists at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has provided the first atomic-scale insights into the ferroelectric properties of nanocrystals. This information will be critical for development of the next generation of nonvolatile data storage devices.
UK scientists will measure the effect on the marine environment and wildlife of devices that harness tide and wave energy using sonar technology that has, for the first time, been successfully deployed on the seabed.
Researchers are working to identify exactly how a changing climate will impact specific elements of weather, such as clouds, rainfall, and lightning. A Tel Aviv University researcher has predicted that for every one degree Celsius of warming, there will be approximately a 10 percent increase in lightning activity.
A multi-institutional team of researchers that included scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. This holds potentially huge possibilities for the application of terahertz technologies across a wide range of fields, including biomedical research, homeland security and ultrahigh-speed communications.
Rising carbon dioxide in atmosphere also speeds carbon loss from forest soils, IU-led research finds
BLOOMINGTON, Ind. -- Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found.
The new evidence supports an emerging view that although forests remove a substantial amount of carbon dioxide from the atmosphere, much of the carbon is being stored in living woody biomass rather than as dead organic matter in soils.
