The Ebola virus is one of the most virulent infections known to science. This special episode of Horizon meets the scientists and doctors from all around the world looking for the cure and hears first-hand accounts of what it is actually like to catch and survive the disease

Could the source of the world’s deadliest viruses hold the secret to a healthier and longer life? Bats have a sinister reputation as potential sources for some of the deadliest disease outbreaks: Ebola, MERS, SARS, and most recently, the virus behind the COVID-19 global pandemic. Yet scientists are discovering new evidence that bats are biological marvels and may hold a key to longevity. They’re resistant to the diseases they carry and have freakishly long lifespans for their tiny size.
So, what’s their secret? And what else can we learn from their peculiar biology? From caves in Thailand and Texas to labs around the globe, the films meets the scientists who are decoding the superpowers of the bat.

Genetic breakthroughs have shed light on how life evolves in real-time. From filling in the missing links to creating a new species, in the last 50 years scientists have solved some of the biggest mysteries of evolution. In this episode, we look at revolutionary discoveries that shook the world and may shape our future.

A look into how the body defends itself against all odds through the stories of a nature survivalist, rancher twins, a doctor who survived Ebola and a cancer therapy recipient. The Immune System, essential to our survival every second, is the most complex and least understood piece of our biology.
