Melbourne, Florida -- Symetrics Industries, LLC announced today an award from the U.S. Army for approximately 300 Improved Data Modems (IDM) for installation on Army aircraft. The contract value will be between US$7 and US$8 million, once final negotiations are completed. The IDM-304 is the Army version of the Improved Data Modems that Symetrics has been delivering to the U.S. Air Force for over 14 years.

Symetrics President and CEO, Mitch Garner stated, "We are absolutely thrilled with this order because it demonstrates the Army's confidence in our ability to execute a long-term, high volume production effort. The IDM-304 is the cornerstone of the Army's airborne element of the Tactical Internet, and Symetrics is proud to be able to provide this critical equipment."

Nearly 30 years after Nobel laureate Linus Pauling famously and controversially suggested that vitamin C supplements can prevent cancer, a team of Johns Hopkins scientists have shown that in mice at least, vitamin C - and potentially other antioxidants - can indeed inhibit the growth of some tumors ¯ just not in the manner suggested by years of investigation.

The conventional wisdom of how antioxidants such as vitamin C help prevent cancer growth is that they grab up volatile oxygen free radical molecules and prevent the damage they are known to do to our delicate DNA.

Scientists at Johns Hopkins have developed a mouse model for schizophrenia in which a mutated gene linked to schizophrenia can be turned on or off at will.

The researchers developed the transgenic mouse by inserting the gene for mutant Disrupted-In-Schizophrenia-1 (DISC-1) into a normal mouse, along with a promoter that enables the gene to be switched on or off. Mutant DISC-1 was previously identified in a Scottish family with a strong history of schizophrenia and related mental disorders.

The study was performed in the laboratory of Mikhail Pletnikov, M.D., Ph.D., in the Department of Psychiatry and Behavioral Sciences.

Infants and children receiving artificial heart-valve replacements face several repeat operations as they grow, since the replacements become too small and must be traded for bigger ones.

Researchers at Children's Hospital Boston have now developed a solution: living, growing valves created in the lab from a patient's own cells.

Pulmonary valves, which provide one-way blood flow from the heart's right ventricle into the pulmonary artery, are often malformed in congenital heart disease, putting an extra burden on the heart.

Enzymes are proteins that act as catalysts in everything from single-celled organisms to humans. They promote chemical reactions in cells and are used widely in industry for everything from making beer and cheese to producing paper and biofuel.

They are also important for making 'natural' drugs, therapeutic agents based on the blueprints of chemicals produced in nature by plants and microorganisms. Such natural sugar-bearing chemicals are the basis for some of medicine's most potent antibiotics and anticancer drugs as exemplified by the antibiotic erythromycin and the anticancer drug doxorubicin.

Important chemical features of such drugs are natural sugars, molecules that often determine a chemical compound's biological effects.

If you look at a price and you see larger numbers on the far right, it makes a difference in how you perceive the discount compared to small numbers on the right even if the actual differences are the same, according to a new study from the Journal of Consumer Research.

So a price of $188 from an original price of $199 appears to be a better deal than a $222 price discounted to $211, even though they are both $11 cheaper.

However, if the left-most digit is small, people perceive they are getting a larger discount when the right digits are “small” -- less than 5 -- rather than when they are “large,” greater than 5.
