KPLU-FM: Keith Seinfeld

Your chances of surviving a sudden heart attack may depend on where you live; some American cities have survival rates five times higher than others. One difference can be 911 dispatchers.

If they coach someone over the phone to give CPR, the chance of surviving goes up. There's now a push to make it universal, but some cities are slow to implement the necessary training.

Becky Cole was eight months pregnant with her fourth child when she collapsed against the bathroom door. It was January 2011 in the Seattle suburb of Woodinville.

Sometimes, couples need help getting pregnant. In Seattle, that help may arrive by bicycle.

To be more specific, a bicycle with a giant sperm cell replica on it.

"It's a delivery bike, purpose-built delivery bike, and inside the front of the sperm we can store one of our cryogenic shipping containers," says Alan Dowden, lab scientist and occasional courier.

Dowden works at the Seattle Sperm Bank. The front of the bike is the bulbous head of a sperm, about the size of very large beach ball, with a long tail stretching behind. It's framed in electric blue.
