LATEST NEWS
Flu vaccination rates lag for at-risk adolescents
November 3, 2008 - Influenza vaccination rates are still far too low for adolescents who suffer from asthma and other illnesses that predispose them to complications from the flu. continue reading >
Simple chemical procedure augments therapeutic potential of stem cells
October 31, 2008 - Researchers have developed a simple method for making a certain class of adult stem cells more therapeutically effective. By attaching a molecule called SLeX to the surface of human cells extracted from bone marrow, researchers have altered how the cells travel through vessels. This might enable the cells to more effectively reach sites of injury and replace damaged tissue. continue reading >
10 Pioneers receive genome data in phase-one of Personal Genome Project
October 20, 2008 - Ten individuals, many of them world renowned researchers, reviewed—and in most cases released—partial coding region data of their genomes in the first phase of a major initiative to make personal genome sequencing more affordable and accessible. continue reading >
Researchers identify achilles heel of common childhood tumor
October 19, 2008 - Researchers have, for the first time, found a mechanism for the rapid growth of the benign blood vessel tumor known as infantile hemangiomas, the most common tumor found in children. The findings implicate gene mutations that facilitate the abnormal activity of a hormone called VEGF, and suggest that anti-VEGF therapies—already approved for other conditions—may be an effective treatment. continue reading >
Novel genetic screens provide panoramic views of cellular systems
October 16, 2008 - Researchers often use the technique of RNA interference (RNAi) to identify genes involved in particular biological processes by knocking them down, one at a time, and observing the result. But this approach fails to capture some key players because many genes are redundant. Thus, cells can mask their distress when they lose a single gene by turning to fail-safes with the same function. A team has now overcome this obstacle, using RNAi to systematically knock down pairs of genes in fruit fly cells. continue reading >
Cross kingdom conflicts on a beetle's back
October 2, 2008 - There's far more to a pine beetle's back than a hard black shell. Researchers have found that these tiny creatures—responsible for rampant and widespread forest destruction—carry on their backs battling species of fungi, plus a powerful antibiotic molecule that can destroy pathogenic fungi—something that no current medications have achieved. continue reading >
