Alexandria, Va. – On July 14, the American Association for Dental Research released its policy statement titled "Oral Health Care within Health Care Reform," which focuses on the scientific base of oral health and its associations to other aspects of health.
New Haven, Conn.—A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change.
By analyzing samples of air taken from the stratosphere—the layer of Earth's atmosphere that sits between six and 30 miles above the surface—the team found a much higher concentration of 16O13C18O at high latitudes than expected. They report their finding in the July 14 issue of the Proceedings of the National Academy of Sciences.
MADISON, WI -- JULY 14, 2009 -- The stress of rising natural gas prices is leading many consumers to rethink how they heat their homes. For some this means moving towards modern alternative energy options, while others have been turning to a more traditional method for a solution to these rising costs. In Canada and the United States, wood burning stoves have been reevaluated as a potentially viable option for home heating.
Dye-sensitized solar cells (DSSCs) are expected to power Air Force unmanned aerial vehicles (UAVs) in the future because they are an optimum energy harvesting source that may lead to longer flight times without refueling.
Carlos became a hurricane for about 24 hours over the previous weekend, then powered down to a tropical storm and now atmospheric conditions have enabled him to power back into a hurricane in the Eastern Pacific Ocean.
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has been capturing images of Carlos since it was born as tropical depression #4E last week. Scientists at NASA can use TRMM data to provide forecasters a 3-D look at the storm's cloud heights and rainfall, which is extremely helpful in forecasting.
Australia's top models will take centre stage in Cairns this week as scientists meet to discuss ways to understand climate change, improve air safety and enhance agricultural sustainability.
The IMACS/MODSIM Congress will attract more than 650 experts in modelling and simulation from Australia and overseas to the Cairns Convention Centre from July 13-17, 2009.
July 14, 2009 (Portland, Ore.) – A reminder program aimed at screening for breast cancer when it is most treatable boosted mammography rates by more than 17 percentage points, according to a new study by Kaiser Permanente's Center for Health Research in the August issue of the American Journal of Preventive Medicine. The program used electronic health records to identify women who would soon be due for a mammogram and reached out to them via postcards, automated voice messages and personal phone calls.
OAK BROOK, Ill. – Obesity, among other factors, is strongly associated with an increased risk of rapid cartilage loss, according to a study published in the August issue of Radiology.
Singapore's Institute for Bioengineering and Nanotechnology (IBN) has discovered a new, environmentally-friendly method to inexpensively synthesize a wide variety of nanoparticles. This new chemical synthesis has been recently published in Nature Materials.
IBN researchers have developed a protocol to transfer metal ions from an aqueous solution to an organic solution such as toluene. Metal compounds that can dissolve in water are inexpensive and commonly available.
Concern over access to clean water is no longer just an issue for the developing world, as California faces its worst drought in recorded history. According to state's Department of Water Resources, supplies in major reservoirs and many groundwater basins are well below average.
With these critical issues looming, researchers at the UCLA Henry Samueli School of Engineering and Applied Science are working hard to help alleviate the state's water deficit with their new mini-mobile-modular (M3) "smart" water desalination and filtration system.
