At the end of a freeway exit near Soccoro, N.M., the hairpin turn onto a gravel road is marked by a sign that warns, "Wrong Way." But it isn't the wrong way if you want to reach the University of New Mexico's (UNM) long-term ecological research (LTER) station. The sign's subterfuge is the first indi

As nonconventional medical treatments become increasingly mainstream, we take a look at the science behind some of the most popular.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.
