The latest episode of GeekWire's sustainability podcast "Positive Charge" dives into human composting — turning a body into clean soil instead of ash or embalmed remains.

It's the option Martha Stewart says she wants, and one of the season's most hopeful episodes. Read more and listen here, and check out more episodes of "Positive Charge" on our show page.

Kalshi hits a wall in Washington: A King County Superior Court judge issued a preliminary injunction against prediction-market company Kalshi, finding the state is likely to prove the fast-growing platform amounts to illegal online gambling.
