The ability to extract trace bits of DNA from soil, water, and even air is revolutionizing science. But it's not foolproof. In the late 1980s, at a federal research facility in Pensacola, Florida, ...

Environmental DNA left behind by ocean animals can be measured to inventory the marine life in a particular area. Measuring marine biodiversity with "environmental DNA" -- an application of gene ...

When we think of city air, we might consider the temperature, smell, wind speed, or even smoke levels. But we probably don't think much about DNA. Research has shown, however, that DNA molecules can ...
