The night time glow of lights picked up by satellite imaging from space predicts the spread of measles in west Africa (Science 2011;334:1424-7, doi:10.1126/science.1210554). In Niger, measles epidemics fluctuate dramatically from one season to the next. Suspecting that population density plays a part, as cities swell in numbers during the dry season and deflate when the rain starts, researchers used light sources from electric lights and fires at night as a measure of human occupancy. Measles transmission rates and population densities were highly correlated. These observations are important for tracking public health issues, for crisis management, and for improving intervention strategies.

Among a cohort of 249 adults who had undergone single bundle anterior cruciate ligament reconstruction, 39% …
