Money really is dirty, according to new research. NYU's Center for Genomics and Systems Biology identified 3,000 forms of bacteria on dollar bills, including some that can cause ulcers, pneumonia, food poisoning, and staph infections.
Even more disturbing is the fact that scientists could only identify 20 percent of the non-human DNA they found on the bills, which means that figure could be a lot higher. The DNA included 1.2 billion segments in all and even included traces of anthrax.
