This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal.

Focuses on three very different siblings, all searching for happiness. Hans-Jörg is a sex addicted librarian, who is interested in young students.

David Attenborough takes us on a guided tour through the secret world of plants, to see things no unaided eye could witness. Each episode in this six-part series focuses on one of the critical stages through which every plant must pass if it is to survive:- travelling, growing, and flowering; struggling with one another; creating alliances with other organisms both plant and animal; and evolving complex ways of surviving in the earth's most ferociously hostile environments.

Geologist Ian Stewart explain in three stages of natural history the crucial interaction of our very planet's physiology and its unique wildlife. Biological evolution is largely driven bu adaptation to conditions such as climate, soil and irrigation, but biotopes were also shaped by wildlife changing earth's surface and climate significantly, even disregarding human activity.

Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

The made-for-cable documentary film The Real Eve is predicated on the theory that the human race can be traced to a common ancestor. The mitochondrial DNA of one prehistoric woman, who lived in Africa, has according to this theory been passed down from generation to generation over a span of 150,000 years, supplying the "chemical energy" to all humankind.
