ou ever thought that bacteria could help solving a crime? Microbiologist Noah Fierer discovered last month that each of us has a unique combination of bacteria sticking on our fingers. These skin bacteria, which are transferred to the objects that we touch, can survive up to two weeks at ambient conditions. Since bacteria can also be removed easily from objects without any contamination, they can serve as a new identification method when fingerprint analysis fails. A quick comparison between the bacteria at the crime scene and those of the suspect’ skin should be enough as an evidence. So if you are planning to commit a crime, think about the bacteria!
