The nation’s power grid remains vulnerable to disruption from extreme events including wildfires, severe storms, and cyberattacks. Variable generation resources and load volatility also present operational challenges to grid stability. To mitigate disruptions before they snowball, grid planners and operators must be able to see these events coming and understand their potential impacts on grid reliability.

The first time salmon were released above Chief Joseph and, later, Grand Coulee dams, Hemene James watched elders from the Coeur d’Alene Tribe. Many weren’t even old enough to remember when salmon last swam in those waters.
In their faces he saw pure emotion, as salmon slipped into the waters where they hadn’t been since Grand Coulee Dam blocked their path in 1942.
Then, he looked at the children. Their excitement was infectious. They jumped and ran into the water, trying to catch the fish swimming upstream.
“It was a little, tiny glimpse of what our world used to be like in the days that the fish were here. So it was very moving and very encouraging,” James says. “This work gets monotonous at times and you feel like you re spinning your wheels. But that was that glimmer of hope from the old ones that you guys are on the right path. Keep moving.”

Wash. lab develops scanner that may eliminate need to remove shoes at airport Eliana Sheriff | KEPR-TV News UP NEXT
RICHLAND, Wash. When you go through the security line at the airport, unless you’re in pre-check, you know the drill. Take off your shoes and put them back on.
But that could be a thing of the past soon, thanks to new shoe scanning technology developed by researchers at a Washington state-based research lab.
Removing your shoes at the airport has only been part of the flying experience since 2006, following multiple threats after 9/11.
Now, researchers with the Pacific Northwest National Laboratory in Richland, who created holographic millimeter scanning technology to detect threats under clothing, has made it possible through shoes.
