As the western U.S. faces decreasing water supplies, WashU alumni are helping negotiate how this precious resource will be managed and shared in years to come.

Researchers at Washington University in St. Louis have used a variety of models to measure ambient concentrations of black carbon in the “global south” and found estimates of these harmful emissions have been grossly underestimated.

Researchers at Washington University in St. Louis reveal that discarded face masks undergo photochemical changes, influencing their surrounding environment.

St. Louis sits on the Mississippi Flyway — the largest migratory pathway used by birds in North America. In this photo story, learn about a long-term study of migratory birds led by volunteers at WashU’s Tyson Research Center that is yielding new data on bird longevity and migration patterns.

The downstream consequences of religion, politics and war can have far-reaching effects on the environment and on the evolutionary processes affecting urban organisms, according to a new analysis from Washington University in St. Louis.

Before venturing out into the woods, a nearby park or even your backyard, keep an eye out for mosquitoes and ticks, which can be vectors, or carriers, for pathogens that can cause disease. Scientists at WashU’s Tyson Research Center explain the risks and how to stay safe.

To help understand air pollution health effects, researchers in St. Louis quantified how the amount of submicron particles in the air has changed over the past 25 years.
