A new study on the surface chemistry of silver-colored, mercury-based dental fillings suggests that the surface forms of mercury may be less toxic than previously thought. It appears online in ACS’ journal Chemical Research in Toxicology. In the study, Graham George and colleagues note that mercury-based fillings, also called amalgams, have been used by dentists to repair teeth for well-over a century. In recent decades...
Scientists searching for the secrets of how calorie-restricted diets increase longevity are reporting discovery of proteins in the fat cells of human volunteers that change as pounds drop off. The proteins could become markers for monitoring or boosting the effectiveness of calorie-restricted diets — the only scientifically proven way of extending life span in animals. Their study appears online in ACS’ Journal of...
Scientists are reporting a discovery of the potential basis for a urine test to diagnose community-acquired pneumonia (CAP), a difficult-to-diagnose disease that is the sixth leading cause of death in the United States. The test could save lives by allowing doctors to begin the right treatment earlier than often occurs at present. The study appears online in ACS’ Journal of Proteome Research...
Scientists are adding additional brush strokes to the revolutionary new image now emerging for star-shaped cells called astrocytes in the brain and spinal cord. Their report, which suggests a key role for astrocytes in morphine’s ability to relieve pain and cause addiction, appears online in ACS’ Journal of Proteome Research, a monthly publication. In the study, Piotr Suder and colleagues…
As they pop the champagne corks to celebrate New Year’s Eve, drug industry executives will likely be glad to put 2009 behind them. That’s because pharmaceutical companies who make top-selling drugs for heart disease, asthma, and many other conditions had a tough year in the midst of mounting market pressures and a global recession. A timely year-end analysis of the state of the pharmaceutical industry is scheduled for the current issue of Chemical & Engineering News, ACS’ weekly newsmagazine...

- Must-reads from C&EN: X-rays by the roll
The simple act of peeling common adhesive tape from a roll triggers the emission of light and flashes of X-rays intense enough to image bones in a finger by exposing commercial dental X-ray film. That’s the latest surprising information from the world of tribology, the study of the physical and chemical phenomena associated with friction, wear, and lubrication. It could lead to new low-cost X-ray sources for scientific research and medical imaging. For a copy of the story, go to X-rays.
