Every time we touch an object, it seems we leave a unique trail of hand germs, or personal bacteria communities,along with our fingerprints, according to a new US study.
The research team from the University of Colorado took swabs from office keyboards and was able to match them to bacteria on the fingertips of individual computer users.
Lead researcher,Professor Noah Fierer, said,"The technique could eventually become a valuable item in the toolbox of forensic scientists." You can say that again. If you have a suspect,you could indict any criminal.
