On April 25, 1953, the science journal Nature announced that James Watson and Francis Crick had discovered the double helix structure of DNA, the molecule that is fundamental to life. But absent from most accounts of their Nobel Prize winning work is the contribution made by a scientist, molecular biologist and crystallographer Rosalind Franklin, who would never know that Watson and Crick had seen a key piece of her data without her permission and that it would lead them to the double helix. Fifty years later, this documentary unravels the mystery behind the discovery of the double helix and investigates the seminal role that Rosalind Franklin and her remarkable X-ray photograph played in one of the greatest discoveries in the history of science.
The ancient Maya civilization of Central America left behind an intricate and mysterious hieroglyphic script, carved on monuments, painted on pottery, and drawn in handmade bark paper books. For centuries, scholars considered it too complex ever to understand until recently, when an ingenious series of breakthroughs finally cracked the code and unleashed a torrent of new insights into the Mayas' turbulent past. For the first time, NOVA presents the epic inside story of how the decoding was done traveling to the remote jungles of southern Mexico and Central America to investigate how the code was broken and what Maya writings now reveal.
