Researchers are reporting evidence from tissue culture experiments that the popular dietary supplement carnosine may help to prevent and treat cataracts, a clouding of the lens of the eye that is a leading cause of vision loss worldwide. The study is scheduled for the July 28 edition of ACS' Biochemistry, a weekly journal.

A joint experiment by researchers at the University of Haifa and Rafael Advanced Defense Systems Ltd. succeeded in solving a 40 year riddle: Could cannon balls from the early 19th century sink warships?

At first glance, the hull of the warship that sank off the coast of Acre seemed strong; but a unique experiment indicated that the thick timbers could not withstand the cannon balls.

Computer scientists at Newcastle University are about to give office workers a perfect excuse to play games: it's all in the name of research.

Dr Jeff Yan, together with his PhD student Su-Yang Yu, has created 'Magic Bullet' as an effective solution to a problem which no known computer algorithm can yet solve.

This simple computer game turns a tedious manual labelling task into a form of light entertainment and could soon help companies improve their chances of tackling online spammers.

While attending university, men are equally likely as women to have been victims of physical or emotional violence, and that violence is often linked to drinking, according to a new study led by University of British Columbia researcher Elizabeth Saewyc.

Remotely sensed imagery is the acquisition of images by satellite and is interpreted through the application of algorithms. These mathematical equations are used to convert light measurements observed by satellites to other types of parameters, such as chlorophyll concentration.

Research in imaging may lead to advancements for the Air Force in data encryption and wide-area photography with high resolution.

Lead researcher Dr. Jason W. Fleischer of Princeton University and his team used a special optical device called a nonlinear crystal, rather than an ordinary lens, to capture images. Every image is made up of a collection of light waves, and a lens bends (refracts) the waves towards a detector. In contrast, in the nonlinear material, these waves "talk" to each other and interact, generating new waves and distorting themselves in the process.

For structures that function in harsh environments like coastal regions or support sensitive equipment, such as magnetic resonance imaging units; the use of fiber reinforced polymer (FRP) is emerging as a valuable option. Because of its natural resistance to corrosion, its high strength, light weight, transparency to electrical and magnetic fields, and ease of manufacturing and installment.

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.
