Potential Medical Applications For Interactive Data Eyeglasses
For car designers, secret agents in the movies and jet fighter pilots, data eyeglasses - also called head-mounted displays, or HMDs for short - are everyday objects. They transport the wearer into virtual worlds or provide the user with data from the real environment. At present these devices can only display information. "We want to make the eyeglasses bidirectional and interactive so that new areas of application can be opened up," says Dr. Michael Scholles, business unit manager at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden. A group of scientists at IPMS is working on a device which incorporates eye tracking - users can influence the content presented by moving their eyes or fixing on certain points in the image. Without having to use any other devices to enter instructions, the wearer can display new content, scroll through the menu or shift picture elements. Scholles believes that the bidirectional data eyeglasses will yield advantages wherever people need to consult additional information but do not have their hands free to operate a keyboard or mouse. The Dresden-based researchers have integrated their system"s eye tracker and image reproduction on a CMOS chip. This makes the HMDs small, light, easy to manufacture and inexpensive.

New Method For Detecting Nitroxyl Will Boost Cardiac Drug Research

Wake Forest University scientists have developed a new research tool in the pursuit of heart medications based on the compound nitroxyl by identifying unique chemical markers for its presence in biological systems. Nitroxyl, a cousin to the blood-vessel relaxing compound nitric oxide, has been shown in studies to strengthen canine heart beats, but research into its potential benefits for humans has been slowed by a lack of specific detection methods. "I think this is a very powerful tool to help in the development of new drugs for congestive heart failure," said S. Bruce King, a professor of chemistry at Wake Forest who leads the team that conducted the research. Researchers can generate nitroxyl from precursor chemicals under controlled conditions, but studying the molecule"s activity in cells is difficult because its constituent elements-nitrogen, oxygen and hydrogen-react so readily with other molecules. King"s research team used compounds that are not present in normal cell biology to produce a reaction that yields the identifying chemical markers. King has been investigating nitrogen oxide compounds at Wake Forest since 1995. While scientists have established that the human body naturally produces nitric oxide, natural production of nitroxyl is suspected but has not been demonstrated. King said the new chemical markers could help answer that question, as well. The research is described in an article, "Reductive Phosphine-Mediated Ligation of Nitroxyl (HNO)," published online in the American Chemical Society"s journal Organic Letters. King co-authored the paper with Wake Forest graduate chemistry students Julie Reisz and Erika Klorig, and chemistry department staff member Marcus Wright, an instrumentation manager. King"s research team has received support from the National Institutes of Health, the National Science Foundation, the American Heart Association and the North Carolina Biotechnology Center.
