Pratt's Lori Setton and Ph.D. candidate Mohammed Shamji have devised a new way to significantly prolong the effects of an anti-inflammatory drug, potentially making it useful for providing longer-lasting treatment for osteoarthritis, the most common form of arthritis. The modified drug, which would be injected directly into arthritic joints, could last for several weeks rather than just the few hours the unmodified drug would last, the researchers said.

A team including David R. Smith, David Schurig and Steven Cummer, all of Duke's Pratt School, has demonstrated the first working "invisibility cloak." The cloak deflects microwave beams so they flow around a "hidden" object inside with little distortion, making it appear almost as if nothing were there at all. Read the whole story.

Mark Wiesner wants to save the planet, one molecule at a time. A nanotechnology expert who joined Duke this semester as a professor of civil and environmental engineering at the Pratt School of Engineering, Wiesner is committed to managing the environmental risks of a growing industrial revolution before any damage is done.

Stephen Smith and graduate student Eric Pua have shown that a three-dimensional ultrasound scanner they developed can successfully guide a surgical robot. The scanner could find application in various medical settings, according to the researchers. They said the scanner ultimately might enable surgeries to be performed without surgeons, a capability that could prove valuable in space stations or other remote locations. Read the whole story.
