Flying through bad weather can be a harrowing experience, and for NASA, it can be doubly unnerving, as violent storms can strike from below the atmosphere or above it. Witness the true power of nature in space and on Earth as astronauts and ground crews battle to overcome the elements, including a severe lightning strike that crippled Apollo 12's computer system, the freezing temps that compromised the Space Shuttle Challenger, and the tempest of space debris that sent a dead satellite on a collision course with the International Space Station.

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.
