Thankful for Science

What EPA researchers are thankful for this year

Are Greenspaces Good for Your Heart?

Innovative EPA research is illuminating the links our environment and our health.

Building A Resilient Shoreline: Lessons Learned from Hurricane Sandy

EPA and partners worked to make a community more resilient after the effects of Hurricane Sandy.

Can Creatures of the Deep Help Track Forever Chemicals in Our Oceans?

Some species of whales have baleen, which are keratin plates that grow down in vertical rows from a whale’s upper jaw instead of teeth, to chomp on their prey. EPA researchers are studying if whale baleen can help track PFAS in our oceans.

EPA Researchers Study Aerosol Transport and Mitigation Measures to Reduce COVID-19 Transmission

EPA researchers are looking at how aerosols spread indoors and investigating technologies that could reduce the amount of virus transmitted.

From Wildfire Smoke to PFAS: Innovative EPA Scientists Address Longstanding Research Gaps

Through the Pathfinder Innovation Projects program, EPA researchers pursue their own novel research ideas that may improve public health and the environment. Learn about PFAS and wildfire projects.

From Exposure to Impact: Developing Adverse Outcome Pathways to Support Chemical Risk Assessment

EPA helped create the AOPWiki to support the crowdsourcing of adverse outcome pathway information and share data with the many researchers worldwide studying responses of organisms to stressors.
