Swab the Subway by Wired

Wondering what kind of bacteria could be found in the subway, during an 18 month project started in 2013 physiology professor Christopher Mason collected samples from all subway stations in New York with the aim of creating a molecular map of the city. All samples were geolocated and analysed and more than 656 species of bacterias were identified. The visualisation shows the microbial map of New York's subway from all bacterias found on the line 1.
