Join Dr. Jeff Marlow and his team as they explore Marum Volcano in the South Pacific. Dr. Marlow discovers life on the edge of Marum which builds a picture of what life might look like on other planets that have more extreme environments than most of Earth.

In 1988 Southeast Asia faced it's own battle with Nipah, a fruit bat-borne disease that kills more than three quarters of those infected. Nipah is only contracted in Bangladesh between the months of December and March, and this was a puzzle at first. It turns out that it is during these months that date palm sap, a national delicacy, is collected. Fruit bats, too, drink this sap, and the sap is thus the vehicle of Nipah transmission. Jonathan Epstein monitors bats in Bangladesh in an effort to prevent Nipah from becoming a global pandemic.
