Sewage Bacteria Reveal Cities' Obesity Rates
benonemusic writes A new frontier in data mining: Researchers at the University of Wisconsin-Milwaukee and the Marine Biological Laboratory in Woods Hole, Massachusetts surveyed bacteria from human waste in the municipal sewage systems. Surprisingly they found different proportions of bacterial species in cities that correlated with obesity rates in those municipal areas. The researchers believe that these bacterial samples can yield city-level information on other diseases as well. Hopefully this isn't just a messy case of spurious correlation.
Yes, but if you want to know how obese a city is you now have a new choice. A) Analyze at remains from the sewer B) Analyze photos from Facebook or C) Spend 5 minutes at the local Walmart.
