Coral Reef Checkup

Coral reefs may look like colorful rocks, but they’re actually animals living in partnership with tiny plant cells. This remarkable symbiosis powers entire ocean ecosystems. In this episode, Dr. Biology chats with Professor Liza Roger, whose Arizona State University lab is home to corals, sea anemones, and even upside-down jellyfish. Together, they uncover the secrets of coral “superpowers,” the causes of bleaching, and how nanoscale medicines might help reefs fight stress. From the desert to the ocean, Roger’s research reveals creative ways to give corals a checkup—and maybe even a healthier future.
