One place that has held off the disease the longest is Alaska. Researchers recently traveled there to search for new clues. It's early morning in southeast Alaska. Stars have yet to fade from the night sky. A group of scientists sets out in search of a different kind of star. Sea stars, commonly known as starfish, have been vanishing from North America's Pacific shoreline. "Almost everywhere we've looked in the last year, we've seen catastrophic losses of sea stars," says Pete Raimondi, a biology professor at the University of California, Santa Cruz, who has been studying an alarming epidemic that's been killing starfish by the millions. Raimondi's team has been tracking the spread of the disease. They noticed signs of the disease in Sitka in the summer of 2013, but there hasn't been a mass die-off until now. Scientists believe that warming water or an infectious pathogen, like a bacteria or virus, may be to blame, but no one knows for certain. Written by
