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 ...

It used to be that if you wanted to find a DNA sequence in a particular sample, you had to go searching for that specific sequence—you had to fish it out with a hook designed especially to catch it.

On a warm, sunny day in April, biologists David Duffy and Jessica Farrell prepare to motor down the Matanzas River on a small boat to catalog the area’s aquatic life. Ripples signal the river’s lazy ...
