10 . Much like our guts (内脏), cities too have various types of microorganisms (微生物) that grow in the environment. And, much like analyzing the microorganisms in our guts can show important details about our physical condition, doing the same thing with a city’s microorganisms can help us understand data on the kinds of bacteria and other small life forms that are living alongside urban people.
While it’s possible to use human researchers to collect data on a city’s microorganisms, that kind of field research can be costly, difficult, and time-consuming. In 2010, honeybees in Brooklyn visited a nearby cherry factory, producing bright-red honey. This caused researchers to examine what other things New York’s honeybees were bringing back to their hives. It struck the researchers that this might be an easier way to collect microorganisms than to search for them on subway poles or sidewalks. So in a new study, researchers decided to seek help from the honeybee, which spends its days exploring cities all over the world, to learn about the urban microenvironments.
The team analyzed hive debris (碎片) from around the world and had some interesting findings. In Sydney, the hive debris showed DNA from microorganisms that can break down rubber, while in Melbourne, a significant amount of DNA from eucalyptus, a kind of tree originally from Australia, appeared at the bottom of hives. And the hive debris from Venice had microorganisms commonly found in rotting wood.
The analysis of Tokyo hives not only found DNA from local unique microorganisms, but also showed the presence of a microorganism that can cause disease among humans. This finding led the team to believe that using bees to learn about urban environments might be a great way to track the spread of human diseases.
While the study is still at the initial stage and it remains to be seen whether honeybees will help scientists find diseases or help city planners make cities greener one day, the insects’ great promise as little research helpers is obvious.
