Caffeinated Mayflies

Water in the Tennessee River isn't going to give you the wake-up jolt that a cup of coffee does.

Caffeine exists in a high-enough concentration to force-feed a typical baby mayfly the equivalent of 26.6 cups of coffee a day, according to Sean Richards, associate professor of biological and environmental sciences at the University of Tennessee at Chattanooga. Caffeine was found in more than93 percent of about 160 test samples of river water.
