Boeing will soon start testing its redesigned Dreamliner battery. Battery experts say that means engineers will have to experiment with flammable lithium-ion batteries to see if, well, they explode. 

Engineers subject the batteries to something called safety abuse testing — crushing them, sticking nails in them — to see what happens.

So how do engineers manage to stay safe? 

The trick, according to battery expert Dan Doughty, is to not get too close.

Federal regulators have approved a Boeing plan to redesign the 787 Dreamliner's fire-prone lithium-ion batteries, although extensive testing will be needed before the planes can fly passengers again.

The Federal Aviation Administration said Tuesday the plan includes a redesign of the internal battery components to minimize the possibility of short-circuiting, better insulation of the battery's eight cells and the addition of a new containment and venting system.

More than 500 workers from Providence St. Peter Hospital are striking this week in Olympia. They’re protesting changes the company has made to their health plans.

The workers include nursing assistants, housekeepers and admitting staff. They say Providence raised their health plan deductibles in January, meaning they have to pay more out of pocket before their insurance kicks in.

REI may soon need a new leader if CEO Sally Jewell is confirmed as Interior Secretary. The next person to lead the outdoor gear retailer will confront a threat from another Northwest company – Amazon.com.

Federal safety investigators so far have been unable to pinpoint the root cause of a 787 Dreamliner battery fire. At the same time, the Federal Aviation Administration is weighing whether to let Boeing move ahead with tests of a new battery design. Does the FAA have to wait for the safety investigation to finish? The short answer is, no.
