NOVA: Deep Sea Invasion
Overview
In 1989 marine biologist Alexandre Meinesz went diving off southern France and was stunned by what he saw: a dense blanket of waving green fronds stretching around him in every direction on the seabed. At first Meinesz had no idea what it was. Then he made the alarming discovery that a tropical alga had taken root in the cold water of the Mediterranean, wiping out native sea life wherever it grew. "Deep Sea Invasion" follows Meinesz on his scientific detective hunt to discover the source of this deadly organism, his uphill battle to alert authorities to its danger, and the struggle to find a non-toxic way to control it.

Episode 14: Dirty Bomb
"Dirty Bomb" probes the realities and implications for public health policy of a disaster that many consider to be all but inevitable: a terrorist attack on a major city using a radioactive "dirty bomb." The program strives to answer crucial questions about this menacing new weapon in the terrorists' arsenal, questions such as: What exactly is a dirty bomb? How dangerous could one be, and how much radiation could it release? What will need to be done to clean up after an explosion?
Episode 16: Secret of Photo 51
On April 25, 1953, James Watson and Francis Crick published their groundbreaking discovery of the double helix structure of DNA, the molecule essential for passing on our genes and the ''secret of life.'' But their crucial breakthrough depended on the pioneering work of another biologistÐRosalind Franklin. She would never know that Watson and Crick had seen a crucial piece of her data without her permission. This was an X-ray image, ''Photo 51,'' that proved to be a vital clue in their decoding of the double helix.
50 years later, NOVA investigates the shocking truth behind one of the greatest scientific discoveries and presents a moving portrait of a brilliant woman in an era of male-dominated science. Sadly, Franklin never lived to see her vital role in the discovery vindicated. While Watson and Crick went on to win the Nobel Prize in 1962, Franklin died in 1958, at 37, from ovarian cancer; and the Nobel is not awarded posthumously.
Hear the inside story from Maurice Wilkins, the colleague who showed her crucial x-ray to Watson; Raymond Gosling, FranklinÕs Ph.D. student with whom she made Photo 51; and Nobel Prize winner Sir Aaron Klug, FranklinÕs last collaborator, who shows new evidence of just how close Franklin came to making the vital double helix discovery herself.
