Scientists at Lehigh University and Cardiff University, reporting in Science magazine, use one of the world's most powerful electron microscopes to map the chemical structure of a nanoparticle that is the active component of a new, environmentally friendly catalyst.

A real time look at interactions between RNA and proteins
For the first time, researchers can now peer inside intact cells to not only identify RNA-binding proteins, but also observe -- in real-time -- the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions.

Guidelines for Yale physician interactions with pharmaceutical industry
To highlight the importance of impeccable financial relationships between the pharmaceutical industry and physicians, the faculty of Yale University School of Medicine has developed and approved some of the most stringent guidelines for the interactions of their faculty with the pharmaceutical industry.

Penn study identifies patients most at-risk for secondary strokes
Researchers at the University of Pennsylvania School of Medicine, and other institutions, have found that severe stenosis of arteries in the head represents a major risk factor for the development of a subsequent stroke.
