Bill Nye and the Discovery Channel give you the greatest discoveries in science. Explore the history of paleontology, beginning at the site of an asteroid that may have brought about the demise of the dinosaurs. Visit Bob Ballard, who discovered new deep-sea life forms, and Douglas Erwin, who demonstrates how fossils provide a vivid snapshot of prehistoric life. Explore Linnaeus' 1735 species classification system and a dramatic re-creation of Darwin's development of his 19th-century theory of evolution.

But in recent years, environmentalists have branded corn as an icon of unsustainable agriculture. It requires large amounts of fertilizer and pesticides, both of which require large amounts of fossil fuel to manufacture. Most of the resulting corn is fed to livestock who didn't evolve to subsist entirely on corn. In cattle, eating corn increases flatulence emissions of methane - a potent greenhouse gas - and creates an intestinal environment rich in e. coli, a common cause of food poisoning.

"They think they are of a kind never before discovered. The well-preserved organisms from the Ordovician period, which began about 495m years ago, lived in what is now the town of Llandrindod Wells, which was partially under water. Scientists believe they shed new light on how ocean communities have evolved."

The TB4000 is a new system that may solve mankind's reliance on fossil fuels, and usher in a golden age of world peace and prosperity.
