AIDS in a new millennium

As we enter the new millennium the world is still facing the challenge of responding to the AIDS pandemic. A new report from the Joint United Nations Programme on HIV/AIDS presents the latest statistics on prevalence, spread, and impact of the disease. In their Perspective, Schwartl?nder and his colleagues discuss the newly released statistics and the strategies needed to combat the further spread of HIV/AIDS and to reduce prevalence in the most severely affected countries.     

Reading without a fovea

A visual mask moving in synchrony with the eye obliterated foveal vision during reading under certain conditions. When foveal vision was masked, reading became difficult. In another condition, a window of readable text moved in synchrony with the eye, and parafoveal vision was masked on each fixation. The results point out the importance of foveal and parafoveal vision in reading.
