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?

NOVA scienceNOW is a News magazine version of the long-running and venerable PBS science program Nova. Premiering on January 25, 2005, the series was originally hosted by Robert Krulwich, who described it as an experiment in coverage of "breaking science, science that's right out of the lab, science that sometimes bumps up against politics, art, culture". At the beginning of season two, Neil deGrasse Tyson replaced Krulwich as the show's host. Tyson announced he would leave the show and was replaced by David Pogue beginning season 6.

PBS' premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA demystifies science and technology, and highlights the people involved in scientific pursuits.

It's death on an unimaginable scale, when a majority of Earth's species quickly die out. It's called "mass extinction," and it's happened at least five times before. Cataclysms, such as supervolcanoes or asteroids, are thought to cause these events, but some experts believe a manmade mass extinction could be next. Is our planet in trouble? And if so, is there anything we can do to stop the next catastrophic annihilation? Experts are traveling the world, performing groundbreaking scientific detective work to answer these very questions.

The rock pocket mouse is a living example of Darwin's process of natural selection. Evolution is happening right now everywhere around us, and adaptive changes can occur in a population with remarkable speed. This is essential if you're a mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. The film features Dr. Michael Nachman, whose work on pocket mice reveals a complete story, from ecosystem to molecules, that demonstrates how random changes in the genome can take many paths to the same adaptation-a colored coat that hides them from predators.

MacArthur is a 1999 television documentary film about Douglas MacArthur, a United States General of the Army.

Written and produced by Austin Hoyt, directed by Hoyt and Sarah Holt, and narrated by David Ogden Stiers.

The enigmatic nature of the Nixon presidency combined comparatively progressive legislative initiatives with a flagrant abuse of presidential power and the public trust. His achievements in expanding peaceful relations with China and the Soviet Union stand in stark contrast with his continuation of the war in Vietnam. Finally brought down by scandal and duplicity, his administration did much to erode the citizenry's faith in government.

He went off to war an unknown soldier and returned a beloved national hero. Often dismissed as a "do-nothing" president and a good-natured bumbler, Dwight D. Eisenhower -- the last American president to be born in the 19th century -- was actually a skillful politician, a tough Cold War warrior, and one of America's most misunderstood and unappreciated presidents. Two-part documentary from American Experience.
