The study, published in the journal "Neurology," was conducted at Seattle Children’s Hospital. It was indirectly funded by the National Football League, part of the millions of dollars the NFL has spent on concussion research.

Scientists say it’s not a matter of if, but of when a devastating earthquake will hit the Pacific Northwest. University of Washington researchers have now done detailed simulations to find out just how intense the shaking from such a quake off the Oregon and Washington coast would be.

After such a glorious summer in the Pacific Northwest, you might be gearing up for the achy joints that many people swear come with cold, wet weather. But a local researcher says your knees could actually get a break when the weather changes.

When there is a solar eclipse, eye doctors do a lot to warn people about the dangers of looking at the sun without proper eye protection.

In May of 2015, Jason Love and Luke Tufts – two friends who met at the University of Washington – went fossil hunting around the Hell Creek Formation in Northeastern Montana, a region known for its fossil sites. On their last day, the two went out on government land to cover some more ground before heading home. “Fifteen minutes into it Jason walked onto to a big boulder with some bones in it,” Tufts said. Those bones ended up being the remains of a Tyrannosaurus rex. Scientists at the museum
