Open microfluidic and nanofluidic systems

... Such a theory has now been developed. This theory addresses the strong capillary forces between substrate material and liquid and takes the ‘freedomâ€TM of contact angles at pinned contact lines into account. Such a contact line is visible in the upper right image in Figure 1. In such a situation, the conta...

Researchers develop rapid diagnostic tool for pathogen identification

... pulmonary disease. This new technology platform addresses important challenges for infectious disease identification—sensitivity and breadth. Mass Tag PCR provides the ability to be precise in identification, as well as the ability to apply current diagnostics to more than one pathogen at a time, thereby re...

FDA Announces Series of Changes to the Class of Marketed Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

...s. The labeling of the prescription NSAIDs already addresses potential skin reactions. This current reexamination of the CV risks of NSAIDs began after Merck conducted a voluntary worldwide withdrawal of its COX-2 selective NSAID, Vioxx (rofecoxib), in September 2004. FDA will carefully review any proposal fr...

...ute genes to the next generation). Hey's approach addresses shortcomings in traditional population genetic studies that rely on just one gene and that assume that population sizes have been constant over time. Studying levels of DNA sequence variation at a single genomic region, or loci, can offer insight int...

Innovative collaboration brings Arctic science into the classroom

...ield sites are in Russia, Canada, and Alaska), and addresses how climate change is impacting the cycles of water and chemicals in the environment. Dr. Holmes has also studied desert streams in the southwestern United States, stream/riparian ecosystems in France, and estuaries in Massachusetts. Dr. Holmes earne...

Researchers track down cause of a disfiguring bone disorder

... these long-range regulatory elements. "Our study addresses a fundamental issue with regard to the majority of the human genome that is noncoding in nature, and its potential impact on human health," Loots said. "Noncoding regions located far away from the genes they regulate are critical for normal gene expr...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

..., interdisciplinary, state-of-the-art science that addresses sediment management in the context of ecological improvement of the Venice lagoon," said Dimitri Deheyn, SIOSED principal investigator and the project's scientific coordinator for Scripps. "Venice is one of the most popular cities in the world and It...

Naturally occurring asbestos linked to lung cancer

...ormation system mapping to pinpoint home or street addresses for every diagnosed individual. A map from the California Department of Conservation, Division of Mines and Geology, served as the reference for ultramafic rock deposits. Finally, statistical adjustments were made for sex, occupational asbestos expos...

Scientists find a maturity gene in fly

...ecular mechanisms are presently unknown. Our study addresses this question using fruit flies, which have many of their genes in common with us and which are ideal for studying genetics." Thummel says the human equivalent of the fruit fly DHR4 gene probably does not work the same way in people as it does in fl...

Dalai Lama, top scientists to discuss science & clinical applications of meditation

Conference addresses western medicine & society's embrace of meditation, press meeting with Dalai Lama, Hopkins Medical Dean Edward Miller, and Georgetown University Professor Aviad Haramati at 8am on Nov. 8 With Western medicine's increasing interest in meditation'...

Chernobyl: The true scale of the accident

...sources on real problems." One key recommendation addresses the fact that large parts of the population, especially in rural areas, still lack accurate information and emphasizes the need to find better ways both to inform the public and to overcome the lack of credibility that hampered previous efforts. Even...

Membrane research opens window to benefits for plants, humans

...said, is a landmark study in membrane channels. It addresses the mechanism of gating and regulation of plasma membrane proteins in full detail. "We could see how every single atom moves and how collective motions of a large number of atoms resulted in the opening of the channel," he said. Aquaporins -- discov...

The bioweapon is in the post

...the scope of these checks varies widely. But email addresses are notoriously easy to fake. And even orders from legitimate institutions may not be what they seem. Alfred Lasher, who manages Picoscript in Houston, Texas, says that he turned down one orderplaced by an individual at a US biotech firm, after Picos...

Immune response to HIV in the brain

Molecule by molecule, new assay shows real-time gene activity

...alysis to highly expressed genes. Xie's new assay addresses all three limitations. He and his colleagues melded a yellow fluorescent protein called Venus with Tsr, a hydrophobic membrane protein. The inclusion of the Tsr domain serves to anchor the fused protein to a cell's membrane, sidestepping the longstan...

Parkinson's disease mechanism discovered

...ice," which modifies, sorts and adds the molecular addresses that designate the specific destinations in the cell where proteins are needed. Lindquist and her colleagues had conducted a genetic screen in yeast to discover genes whose activity affected the toxicity of alpha-synuclein. That study showed that ge...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

...st wrong." What causes pauses? The study also addresses a long-standing question about enzyme memory: If an enzyme pauses at one DNA site, will it alter its behavior when it encounters the same sequence again? "It turns out that RNAP enzymes may have individual personalities, but no memories," Herbert exp...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens
