The Boston T is the United States' oldest subway system, dating back to a single street car commissioned in 1897. The most infamous study on subway life was published last year about New York. A team from Harvard set out to understand these microbial communities in their backyard of Boston. Scientists have long considered the subway system an environment unto itself that's different from any other place on Earth, but little is known about this ecosystem. There were also Micrococcaceae and Streptococcaceae from the oral cavity that tend to move from place to place through coughing or sneezing.
