In this two-hour special, NOVA captures the turmoil that tore apart the community of Dover, Pennsylvania in one of the latest battles over teaching evolution in public schools. Featuring trial reenactments based on court transcripts and interviews with key participants, including expert scientists and Dover parents, teachers, and town officials, "Judgment Day: Intelligent Design on Trial" follows the celebrated federal case of Kitzmiller v. Dover School District. This program was coproduced with Paul G. Allen's Vulcan Productions, Inc. In 2004, the Dover school board ordered science teachers to read a statement to high school biology students suggesting that there is an alternative to Darwin's theory of evolution called intelligent design–the idea that life is too complex to have evolved naturally and therefore must have been designed by an intelligent agent. The teachers refused to comply. Later, parents opposed to intelligent design filed a lawsuit in federal court accusing the school board of violating the constitutional separation of church and state. "There was a blow-up like you couldn't believe," Bill Buckingham, head of the school board's curriculum committee, tells NOVA. Buckingham helped formulate the intelligent-design policy when he noticed that the biology textbook chosen by teachers for classroom use was, in his words, "laced with Darwinism." NOVA presents the arguments by lawyers and expert witnesses in riveting detail and provides an eye-opening crash course on questions such as "What is evolution?" and "Is intelligent design a scientifically valid alternative?" Kitzmiller v. Dover was the first legal test of intelligent design as a scientific theory, with the plaintiffs arguing that it is a thinly veiled form of creationism, the view that a literal interpretation of the Bible accounts for all observed facts about nature. During the trial, lawyers for the plaintiffs showed that evolution is one of the best-tested and most thoroughly con

The Mofu people of northern Cameroon have a close relationship with insects, in particular, the red driver ants which they use to combat termites.

In the early 1950s, epic battles unfolded in the skies over North Korea as American and Russian fighters faced off in history's first jet war. This program explores the Korean War's aerial tactics, technology, and grim aftermath for downed pilots, many of whom disappeared without a trace. The Korean War pitted the two most advanced fighters of their day, the American F-86 Sabre and the Soviet MiG-15, in furious air battles in North Korea's notorious "MiG Alley." With the help of dramatic reconstructions, rare archival footage, and interviews with veteran American and Soviet pilots, NOVA puts viewers in the cockpit to experience the lethal split-second duels that erupted in MiG Alley.
