Researchers develop rapid diagnostic tool for pathogen identification

...ecise in identification, as well as the ability to apply current diagnostics to more than one pathogen at a time, thereby reducing the time needed for differential diagnosis. “We focused first on respiratory diseases because differential diagnosis is a common clinical problem with implications for outbrea...

Genrate: a generative model that finds and scores new genes and exons in genomic microarray data

...lutions are found using an efficient algorithm. We apply GenRate to a subset of mouse genome-wide expression data that we have created, and discuss the statistical significance of the genes found by GenRate. Three of the highest-ranking gene structures found by GenRate, each containing thousands of bases f...

International HapMap consortium expands mapping effort

... longevity. "We are excited by the opportunity to apply our technology to all publicly available SNPs. This effort is so important that Perlegen is willing to contribute some of its own resources to make this possible," said Kelly A. Frazer, Ph.D., vice president of genomics at Perlegen. "We are confident...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...ew landowners from outside the Pantanal frequently apply non-sustainable practices." "Prior to the 1970s, the traditional stakeholders had limited impact on the resources they used and did not have the means to induce major environmental changes, such as altering the flood pulse by building dams or changi...

UCSD discovery may help extend life of natural pesticide

...g sought-after Bt receptor. However, their results apply to insects as well. Michael Adang and Stephan Garczynski, coauthors and entomologists at the University of Georgia, showed that the glycolipid receptor is present in the tobacco hornworm, an insect pest that is susceptible to Bt toxins used commercia...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...e that the classic inheritance rules didn't always apply was the discovery of normal flowers on some offspring of mutant plants. In the deformed parents, the flowers were fused into tight balls. But in the grandparents and 10 percent of the grandchildren, the buds become 1-millimeter-long, bright white flo...

Open microfluidic and nanofluidic systems

.... However, the same morphology diagram should also apply to other liquids and other substrate materials. It should also remain valid if one further shrinks the surface channels and, in this way, moves deeper into the nanoregime. As one reaches a channel width of about 30 nanometer, one theoretically expect...

Upon release, if they remained apart it revealed they wereseparated; but if they snapped back together the researchers would knowthe chromatids were still attached. Paliulis was a Duke graduatestudent when she performed the e...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

... The muscle-targeted gene therapy might therefore apply to other forms of muscular dystrophy, they added. Muscular dystrophies include many genetic diseases, all of which are characterized by progressive weakness and degeneration of the skeletal muscles which control movement. The Muscular Dystrophy Asso...

Solution to Pollution: New Bacteria Eats Toxic Waste

.... The site had been used by industry as a place to apply preservatives to wood, yet Sims found the land to be relatively free of toxins and asked the question, why? After conducting soil analysis tests, Sims found microbes in the soil that had destroyed the toxic chemicals. Sims then collaborated with res...

Sea skate experiment sheds light on human cell transport

...t of cells," Goldstein said. "The idea that we can apply this knowledge to other cells and other animals ?including humans ?is what makes the findings exciting." In type 1 diabetes, cells lose their ability to transport glucose. Goldstein and Musch say their findings could explain the problem. People with...
