One of the Apollo 14 astronauts took a bag of tree seeds to the moon. A few years after the astronauts returned home, some of the seeds were planted across the United States... and then forgotten. Anthony and Jeff discuss the effort to track down these Moon Trees, and if they really mean something. Then, researchers have directly observed what happens inside the brain of a zebra fish when it is being traumatized. Jeff and Anthony talk about what this breakthrough means, and how exactly the scientists traumatized those fish.
