Leaving a Legacy: Plants leave “memories” in the soil that can affect future generations

It’s easy to drive by grasslands, forests, and deserts without thinking too deeply about how and why they have developed to be unique from one another.

Microplastics take flight—how mosquitoes move microscopic pollutants from water to land

Discarded plastics aren’t only disrupting the ocean, they accumulate in freshwaters too. And the impacts may not end there. Aquatic insects eat microplastics and, when they become adults, carry the polluting particles from water onto land and potentially into the stomachs of their predators.

Oil Spills are a Black Mark on Health

The thought of oil spills conjures up images of marine disasters–wildlife smothered in slick sludge and thick black smoke. But what are the human health consequences to the brave men and women who respond and work to clean up these messes? New research examines the potential impact of oil spill response work on risk of heart attack in those who clean up after the Deepwater Horizon disaster.
