In the race to cure cancer, researchers look for roadblocks that could stop cancer in its tracks, preventing it from spreading to other parts of the body. Scientists from the University of Wisconsin-Madison may have found that blockade – an enzyme critical to the ability of cells to metastasize, a biological phenomenon by which cells migrate. The findings are published in the Nov. 7 issue of the journal Nature.
“The real, life-threatening problem with most cancers is that they migrate away
Put aside images of World War II espionage and codebreaking. Today cryptography is vital to the security of a form of communication and commerce never imagined 60 years ago: the Internet. Researchers at Northwestern University now have demonstrated a new high-speed quantum cryptography method that uses the properties of light to encrypt information into a form of code that can only be cracked by violating the physical laws of nature.
In the open and global communication world of the Interne
A new lightning index that uses measurements of water vapor in the atmosphere from Global Positioning Systems has improved lead-time for predicting the first lightning strikes from thunderstorms. The index will help greatly aid NASA Space Shuttle launches at Kennedy Space Center, Fla, and other commercial and U.S. Department of Defense launches from Cape Canaveral Air Force Station, Fla.
“Better forecasting and more advance warning of lightning strikes will help reduce the delays or cancell
Oak Ridge National Laboratory and 3M Company are hoping for powerful results from a project aimed at making transmitting electricity more efficient and reliable.
Researchers from 3M, working with ORNL, are developing a promising replacement conductor for conventional power lines that addresses the problem of power outages caused by sagging lines. Lines sag under the heat of high current loads. The replacement conductor also avoids the high cost and environmentally harmful effects of buildin
The movements of two gigantic Antarctic icebergs appear to have dramatically reduced the number of Emperor penguins living and breeding in a colony at Cape Crozier, according to two researchers who visited the site last month. The colony is one of the first ever visited by human beings early in the 20th century.
“Its certain that the number of breeding birds is way down” from previous years, said Gerald Kooyman, a National Science Foundation-funded researcher at the Scripps Institution
2002 Outbreak May Claim 10,000 Harbor Seals
Scientists from Göteborg University in Sweden and the Woods Hole Oceanographic Institution (WHOI) report in an upcoming issue of the journal Ecology Letters that the 2002 outbreak of phocine distemper virus, or PDV, in European harbor seals may reduce the population by more than half and that future outbreaks with similar characteristics would significantly increase the risk of population declines. Their findings are the first epidemiol
