Imagine yourself immersed in a chilly, blue, three-dimensional world, one where vision isn’t much use but sound travels far. That’s the leap of the imagination demanded of scientists like Volker Deecke who study killer whales. Deecke and his colleagues must sort myth from science to learn the secrets of these consummate predators. Ari Daniel Shapiro reports from the Shetland Islands.

You have probably seen cans of tuna in your local supermarket marked “dolphin safe.” That label means the tuna was fished in a way that spares most dolphins from being killed in the tuna fleet’s giant nets. In this podcast, biologist and guest reporter Matt Leslie brings us a story about tuna, the intertwined fate of fisheries and dolphins, and the work of scientists. It’s a story that lies behind the label of every can of tuna. It spans two generations of scientists and a revolution in scientific methods. Matt reports from a dolphin morgue in La Jolla, California, USA.
