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.

Just over 100 years ago, cutting into the brain was a terrifying prospect for both patient and surgeon. They could expect the result to be the surgeon bloodied and defeated, and the patient dead. From freak accidents involving crowbars through the skull to notorious lobotomies with icepicks, this programme reveals how, through mishap and misadventure, brain surgery has become the life-saving discipline it is today.

The universe is hiding something. In fact, it is hiding a lot. Everything we experience on Earth, the stars and galaxies we see in the cosmos—all the “normal” matter and energy that we understand—make up only 5% of the known universe. The other 95% is made up of two mysterious components: “dark matter” and “dark energy.” We can’t see them, but we know they’re there. And what’s more—these two shadowy ingredients are locked in an epic battle to control the very fate of the universe. Now, scientists are trying to shed light on the so-called “dark sector” as the latest generation of detectors rev up, and powerful telescopes peer deeper into space than ever before to observe how it behaves. Will the discoveries help reveal how galaxies formed? In the series finale, NOVA Wonders journeys to the stars and back to investigate what we know—and don’t know. Find out how scientists are discovering new secrets about the history of the universe, and why they’re predicting a shocking future.
