Humans have sought new materials to make elusive blue pigments for millennia—with mixed success. Today, scientists are tackling this blue-hued problem from many different angles. Host Sarah Crespi talks with contributing correspondent Kai Kupferschmidt about how scientists are looking to algae, bacteria, flowers—even minerals from deep under Earth’s crust—in the age-old quest for the rarest of pigments.


Also this week, host Meagan Cantwell speaks with Andrew Whitehead, associate professor in the department of environmental toxicology at the University of California, Davis, about how the Atlantic killifish rescued its cousin, the gulf killifish, from extreme pollution. Whitehead talks about how a gene exchange occurred between these species that normally live thousands of kilometers apart, and whether this research could inform future conservation efforts.
