Sushi seems like the perfect modern food: Light, healthful and available at seemingly every supermarket in the nation. But is it sustainable?

That's the question behind "The Story of Sushi," a new video that's been pulling a lot of clicks in the past week.

It’s a tough commute out there for anyone who has to drive. Snow is melting fast, and ice is a big danger.

But in Seattle at least, the consensus seems to be that the city has improved a lot in keeping main arterials clear, by deploying trucks that preemptively spray de-icer and sprinkle rock salt on the roads when it snows.
