MASTER OF THE MIND - Correspondent Sharyn Alfonsi reports on a groundbreaking approach to brain surgery that could revolutionize the treatment of Alzheimer's disease and drug addiction without any incisions. Alfonsi follows neuroscience pioneer Dr. Ali Rezai for more than a year as he tests experimental procedures at the Rockefeller Neuroscience Institute in Morgantown, W.Va. The results of Rezai's clinical trials are changing the lives of his patients and may offer hope to others suffering from brain disorders. This is a double-length segment. Guy Campanile is the producer of part one. Campanile and Lucy Hatcher are the producers of part two.

SEALAND - Correspondent Jon Wertheim journeys by boat (and winch) into the world's smallest - and unlikeliest - state: the Principality of Sealand. Just off the English coast, and roughly the landmass of two tennis courts, it boasts a full-time population of one. It was built during World War II as a nautical fort, and later repurposed as a "pirate radio" station under its monarchs, the Bates family. Wertheim takes a tour of this micronation and explores its history of piracy, coups, countercoups and rogues. Michael Gavshon is the producer.
