Untangling Alzheimer's is a dramatic and inspiring medical investigation driven by David Suzuki's journey to understand the science of Alzheimer's and the surprising new insights into its cause. David has a very personal interest in the disease because his mother, aunt and two uncles died of it. We join David on an intimate journey as he explores the newest breakthroughs in this devastating disease as well as his own chances of contracting the cruel condition. Alzheimer's today is the only leading cause of death that cannot be cured, prevented or even slowed. Worse, it's the only leading cause of death that is on the rise – and not simply because baby-boomers are getting older. Studies show that the increase is absolute across all age groups, and death rates continue to climb. With a new case developing every 69 seconds, scientists now speak of the Alzheimer's epidemic.

Second Genesis follows planetary scientist Carolyn Porco as she explores what it takes to look for life beyond Earth, and what conditions are required for life to exist. Porco makes the case that Saturn’s moon Enceladus—with its plumes of water vapor spewing into space, confirmed organic materials, and evidence of hydrothermal vents at the bottom of its liquid ocean—is the most promising place to look. Could Enceladus be the key to proving once and for all that life is not unique to Earth? And what it would mean—both scientifically, and spiritually—if we found evidence of a true second genesis right here in our own galactic back yard?
