Future Of Sumatran Tigers Threatened By Human Disturbances
2012-03-01 04:52:51

Three of the world's subspecies of tigers are now extinct. A new study found that the Sumatran tiger subspecies is nearing extinction as a result of human activities, particularly the conversion of natural forests into forestry and agricultural plantations, leading to habitat loss. The study, conducted by Virginia Tech and World Wildlife Fund (WWF), is the first of its kind to systematically investigate the use of different land cover types – not just forests but also plantation...

Wake Forest University School of Biomedical Engineering and Sciences (SBES) announces the first ever publication with data on head impacts from youth football players. The paper is published in the Annals of Biomedical Engineering and is available online for free download. The manuscript includes the details of over 700 head impacts measured on 7 and 8 year old youth football players. Based on the importance of this initial publication, the School of Biomedical Engineering and Sciences is...

Scientists have developed a new community resource that may act as a Rosetta stone for revealing the genetic basis of traits and disease. A paper in the Feb. 9 issue of Nature describes the Drosophila Genetic Reference Panel (DGRP), which provides the highest-resolution view to date, of the genome structure and variation in a population of 192 fruit flies with diverse traits. The study was led by Trudy Mackay, professor of genetics at North Carolina State University, in collaboration with...

As scientific researchers become evermore competitive for scarce funding, scientific journals are increasing efforts to identify submissions that plagiarize the work of others. Still, it may take years to identify and retract the plagiarized papers and give credit to the actual researchers. "We need a better system," said Harold Garner, executive director of the Virginia Bioinformatics Institute at Virginia Tech. Garner discussed the problem and solution in a Comment in the January 4, 2012...

As mosquito-borne viral diseases like West Nile fever, dengue fever, and chikungunya fever spread rapidly around the globe, scientists at Virginia Tech are working to understand the mosquito's immune system and how the viral pathogens that cause these diseases are able to overcome it to be transmitted to human and animal hosts. In nearly every part of the world, humans and animals experience high levels of morbidity and mortality after being bitten by mosquitoes infected with viruses. More...

HokieSpeed Is A New Powerful Supercomputer For The Masses
2011-12-22 05:15:09

Virginia Tech crashed the supercomputing arena in 2003 with System X, a machine that placed the university among the world's top computational research facilities. Now comes HokieSpeed, a new supercomputer that is up to 22 times faster and yet a quarter of the size of X, boasting a single-precision peak of 455 teraflops, or 455 trillion operations per second, and a double-precision peak of 240 teraflops, or 240 trillion operations per second. That's enough computational capability to place...

If this year's holiday period is anything like the last, seniors should be advised that, along with seasonal elevations of joy and good cheer, the risk of falling victim to elder financial abuse is also increasing. Older adults need to know the warning signals of financial abuse and exploitation, how to prevent it, and what to do if it does occur. According to research conducted by Karen A. Roberto, director of the Center for Gerontology at Virginia Tech, of the 1,128 news articles on...

A protein called enhanced disease susceptibility 1 (EDS1) plays a central role in plants' ability to defend themselves from pathogens. But in the almost two decades since it was discovered, how EDS1 works at the molecular level has been a mystery. Solving the mystery will help scientists enhance disease resistance in crops. Two papers published in the Dec. 9 issue of Science (http://www.sciencemag.org/magazine) demonstrate how EDS1 activates different components of the plant immune system,...
