Brenden Foley hunts ancient shipwrecks for a living. But he's not after sunken treasure--he's after information. Foley is a marine archeologist at the Woods Hole Oceanographic Institution. He's taking a new approach to the field. Instead of just focusing on a handful of shipwrecks, he wants to take a broad look, finding and cataloging wrecks in the Mediterranean that date to a wide timeframe. In this podcast, he talks to us about his work.

Ecologist Charlie Crisafulli describes how the ecosystem around Mt. St. Helens is rebuilding itself 30 years after the catastrophic eruption.

Thirty years ago, a violent eruption ripped through the side of Mt. St. Helens in western Oregon. The blast killed 57 people and countless animals, and turned hundreds of miles of forest into barren wasteland. In this podcast, hear from ecologist Charlie Crisafulli on the slow recovery of the Mt. St. Helens ecosystem, and learn how the timing of the eruption actually spared some plant and animal life.

In order to develop from an embryo, animals as different as fruit flies and humans call on a nearly identical set of genes. But how does this one common genetic toolkit create so many different species? It turns out that it's not the genes you have--it's how you use them.

After Pluto was discovered in 1930, it enjoyed the title of planet for more than 75 years. But in 2006, that all changed. At a meeting in Prague, the International Astronomical Union adopted a new definition for planethood, leaving the solar system with only eight planets. But not everyone agrees with its decision. In this podcast, planetary scientist Alan Stern talks to us about Pluto's demotion, and why he thinks it should be back on list of planets.

For Chief Anne "Little Fawn" Richardson, Pocahontas is more than a legendary historical figure. Richardson can trace her own ancestry back to the 17th century, when her tribe, the Rappahannocks, were part of a vast domain ruled by Pocahontas's father. In this podcast, Richardson reflects on the clash of cultures between Pocahontas's people and the English settlers of Jamestown.

Galileo has been called the "father of modern science". His observations of the night sky in the early 1600s confirmed a new model of the universe, where the Earth orbited the sun—not the other way around. But before he was studying the universe, Galileo was working on practical problems. And his early goals for the telescope weren't so scientific.
