For 12 years, researchers in Washington and British Columbia have been tracking down a mystery. 

Along the Pacific coast, sea stars were dissolving into goo. This phenomenon was given a name: sea star wasting disease and it killed billions of these marine creatures. 

For more than a decade, scientists studied the wasting disease but couldn’t figure out why it was happening. 

A new paper published this week in Nature Ecology and Evolution details a likely culprit.
