Expert-witness physicians who specialize in interpreting chest x-rays for plaintiffs in lawsuits claiming asbestos-related injury greatly overstate their findings, compared with independent readers interpreting the same films without knowing their source, reports the August issue of Academic Radiology, published by Elsevier on behalf of the Association of University Radiologists.
In a study of 492 chest x-rays obtained by plaintiffs lawyers and entered as evidence in lawsuits against former employers, the original interpreters claimed to find evidence of possible asbestos-related lung damage in 95.9 percent of cases. In contrast, when the same x-rays were re-read by six unbiased physicians, the abnormality rate was only 4.5 percent.*
An accompanying editorial remarked on the studys possible impact on thousands of pending claims for billions of dollars against hundreds of companies.† More than 60 U.S. companies have taken voluntary bankruptcy to protect their assets against asbestos-related lawsuits.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
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...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
