Submission + - Scientists Are Now Tracking the Spread of Diseases (

HansonMB writes: Call it researching disease in the cloud or just plain illuminating, but Princeton researchers today published a paper in Science that demonstrates how aerial night images can be used to monitor the spread of epidemic in the developing world by tracking light density.

That’s a mouthful, but the concept is really pretty straightforward. In developing nations with migratory populations, there are parts of the year when everyone tends to meet up, creating localized, seasonal population booms. Those booms, with a large number of people in a concentrated area, are a hotspot for the spread of disease. Unfortunately for health agencies, tracking migratory populations has never been an easy task, which means epidemic can get out of hand quickly.
