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.

So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
