The Environmental Protection Agency (EPA) publishes the "Science Matters" newsletter to inform the general public about its research and advocacy activities on behalf of the American public. The newsletter was first published in 2010, and is a terrific source of information on everything from green chemistry to renewable energy. In the About this Issue area, visitors can learn about the topical focus of each issue. In the Science Features, visitors can read articles such as "Nanomaterials: Harnessing the Potential, Understanding the Risks" and "Partnerships for a Safer Chemical Future." Users shouldn't miss the Ask a Scientist feature, which profiles a different EPA scientist in each issue. The In the News area brings together updates about new partnerships with colleges, universities, and international collaborators. [KMG]
