Our top stories address emerging challenges in community and workplace health and safety

This year, communities and workplaces in Washington state and beyond faced emerging challenges, including the rising cost of food, power outages linked with extreme weather events, and infectious diseases such as avian flu. Many of our most-read stories of the year reflect our faculty, staff and students’ ongoing work to understand these hurdles and help create solutions. 

Beyond our blog, two UW News videos highlighted federal funding obstacles for our department's efforts to turn seaweed into a soil amendment for vegetable farmers and to protect workers in Washington state.

Our department also welcomed four new faculty members this year, and we look forward to introducing our new department chair soon. In other annual highlights, microbiologist Rita Colwell gave the 2025 Omenn Lecture to a standing-room-only crowd, and policy expert Jordan Barab shared timely thoughts on workplace health and safety in the current political landscape in his 2025 Breysse Lecture. 

Thank you for reading, collaborating and supporting our work, and we are excited to connect with you in 2026. Take a look back at our top 10 stories below.
