Summary

News stories on bees that live perilously close to the mouth of a volcano, diagnosing arthritis in dinosaur bones, and the evolution of the female orgasm, with David Grimm. From the magazine Rivers deliver water to the ocean but water is also discharged along the coast in a much more diffuse way. This “submarine groundwater discharge” carries dissolved chemicals out to sea. But the underground nature of these outflows makes them difficult to quantify. Audrey Sawyer talks with Sarah Crespi about the scale of this discharge and how it affects coastal waters surrounding the United States.

1:07.6	First up, we have a story on bees that live dangerously, and I mean really
1:12.2	dangerously, on the side of a volcano in a place called the kill zone. Okay, I guess they're not
1:18.9	going to be making honeycomb up there. What are they doing, Dave? They are surprisingly buzzing
