To look at far off galaxies and ozone destruction closer to Earth Scientists from Virginia Tech and the University of Colorado are preparing to launch two NASA sounding rockets for two experiments at Poker Flat Research Range north of Fairbanks. The launch window for both experiments opens on Jan. 26 and extends until Feb. 15. In the experiment set to launch on Jan. 26, if winds are favorable, researchers from the University of Colorado will use a rocket at the top of its arc 200 miles above...

In the first phase of a more than two-year study funded by InterDigital, Virginia Tech researchers have made great strides in the development of more reliable and efficient spectrum sensing techniques that will be needed to meet the ever-expanding demand for wireless technologies. "The U.S. government has noted that broadband wireless access technologies are a key foundation for economic growth, job creation, global competitiveness, and a better way of life," explained Claudio da Silva, an...

Just as raging hormones are part of the process of a child's maturation through the teen years to adulthood, juvenile hormones, a group of insect isoprenoids, play an important role as butterflies, fruit flies and mosquitoes transform their body structures as they molt from larva to pupa and then adults. Unlike humans, in insects the juvenile hormone inhibits development of adult characteristics until the insects reach a proper stage. Juvenile hormones also play a prominent role in regulating...

A new genetic biomarker that indicates an increased risk for developing breast cancer can be found in an individual's "junk" (non-coding) DNA, according to a new study featuring work from researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues. The multidisciplinary team found that longer DNA sequences of a repetitive microsatellite were much more likely to be present in breast cancer patients than healthy volunteers. The particular repeated DNA...

As the U.S. policy makers renew emphasis on the use of nuclear energy in their efforts to reduce the country's oil dependence, other factors come into play. One concern of paramount importance is the seismic hazard at the site where nuclear reactors are located. Russell A. Green, associate professor of civil and environmental engineering at Virginia Tech, spent five years as an earthquake engineer for the U.S. Defense Nuclear Facilities Safety Board in Washington, D.C., prior to becoming a...

New research finds that crop-killing mildews are able to sneak into plants undetected as "stealth bombers" by shedding genes to conceal themselves thus thwarting the plants' defenses. In a pair of studies, researchers mapped the genomes of two of the plant-killing mildews, and then described how the diseases shed giveaway genes to trigger an immune attack in the host plants. Although powdery mildew plagues seem to come out of nowhere,  they can devastate barley, corn, grapes, potatoes...

Researchers at the Virginia Bioinformatics Institute at Virginia Tech have discovered how abscisic acid, a natural plant hormone with known beneficial properties for the treatment of disease, helps fight inflammation. The results (http://www.ncbi.nlm.nih.gov/pubmed/210882970), which are published in the November 2010 Journal of Biological Chemistry, reveal important new drug targets for the development of treatments for inflammatory and immune-mediated diseases. The scientists had reported...

Scientists at the Virginia Bioinformatics Institute at Virginia Tech have discovered some of the key molecular events in the immune system that contribute to inflammatory bowel disease. The results, which help researchers move one step further in their efforts to develop new drugs to treat inflammatory and immune-mediated diseases, are reported in the November 2010 edition (http://www.ncbi.nlm.nih.gov/pubmed/21068720) of the journal Mucosal Immunology from the Nature Publishing Group....


Word of the Day
