As U.S. consumers seek reassurance that their hamburgers and steaks are free of deadly mad cow disease, researchers at the University of California-San Francisco say they may have found a promising solution. Theyve developed a faster, more reliable test for identifying the disease, possibly even in living cows. Current tests can only detect the disease after the cow dies.
The test was described today at the 226th national meeting of the American Chemical Society, the worlds largest scientific society.
Critics argue that the standard immunoassay tests used to identify the infectious prion proteins that cause mad cow disease are inadequate for large scale screening of cattle. The tests can produce false readings and may take a week to yield results. A better test is needed, they say.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
