Disintegrating sea stars—a process described as melting, with the arms detaching and crawling away from each other—is being caused by a virus that’s been detected in West Coast waters for more than 70 years. That’s according to new findings published in late November in the Proceedings of the National Academy of Sciences by 24 co-authors including the University of Washington’s Carolyn Friedman, a professor of aquatic and fishery sciences, and Colleen Burge, who earned her bachelor’s and doctorate from UW and is now back as a postdoctoral researcher here after four years of postdoc work at Cornell University.
