Nature features scientists' work University scientists unveiled in the February 11 issue of Nature a new class of optical materials that efficiently creates the kind of light prized by manufacturers of displays for computers, televisions, and entertainment systems. Light emerges by twisting its way through thousands of layers of molecules, spiraling from one side to the other. The material includes special additives, or dopants, that allow it to emit and manipulate color light without color filter arrays, which are necessary in today's display systems. The findings were possible thanks to a laser-based system developed by David Williams and colleagues at the University over the last decade that maps out the topography of the inner eye. The idea is to correct for aberrations in the atmosphere so that rays of light travel in parallel lines and converge at a single point, delivering a sharp image.
Astronomers use the technique in telescopes to grab ever-better photos of the heavens.
Williams, director of the Center for Visual Science, leads an effort to apply the same technology to human vision. Robot technology aids pharmacy Pharmacists at Strong Memorial Hospital have teamed with a new drug-dispensing robot. This pharmacy automation enhances care by freeing pharmacists from routine tasks so they can spend more time with patients. The medication dispensing system, ScriptPro SP 200, was recently installed in the Outpatient Pharmacy at Strong to improve customer service and quality of care for hundreds of people. The pharmacist then places the prescription into the pharmacy's computer, which activates the robot.
