Each day, some 2.5 trillion bytes of data are exchanged, a deluge known as "big data." How can we classify, store, and give meaning to this mass of digital information? Will our digital society remain capable of producing a lasting memory? Learn the fate of memory storage in the future.
Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.
When Harvard PhD student Jennifer Brea is struck down at 28 by a fever that leaves her bedridden, doctors tell her it’s "all in her head." Determined to live, she sets out on a virtual journey to document her story—and four other families' stories—fighting a disease medicine forgot.
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?
Unlocking the Mystery of Life represents a unique programming opportunity for local stations. Its broadcast release coincides with the 50th anniversary of one of the greatest scientific breakthroughs in history-James Watson and Francis Crick's discovery that the DNA molecule carries hereditary information in the form of a code that many scientists have likened to computer software or a written language. This discovery (announced on April 25,1953) sparked a scientific revolution. But it also left a fundamental question unanswered. Where did the information in DNA come from? How did the software in the cell arise? Unlocking the Mystery of Life explores these questions through the stories of a growing number of scientists who no longer believe that natural selection or chemistry, alone, can explain life's origin. Instead, they think that the microscopic world of the cell provides evidence of purpose and design in nature.
A scientific film essay, narrated by Phil Morrison. A set of pictures of two picnickers in a park, with the area of each frame one-tenth the size of the one before. Starting from a view of the entire known universe, the camera gradually zooms in until we are viewing the subatomic particles on a man's hand.
It's a condition known as "hypertrichosis" or "Ambras Syndrome," but in the 1500s it would transform one man into a national sensation and iconic fairy-tale character. His name: Petrus Gonsalvus, more commonly known today as the hairy hero of Beauty and the Beast.
This narrated computer animation, with an original musical score, illuminates cellular mitosis. DNA self-replicates; chromosomes divide into two daughter cells; but it begins with a hormone entering the nucleus of a cell.
In the void created ad hoc to throw us into desperation, fear, shock, the torment of an infinite present, Arto Lindsay sings with words, silences and small gestures of/with/for/about love, a force that is so violent that nothing will ever be the same again.
A documentary about Rosalind Franklin, the scientist who first photographed and discovered the shape of DNA.
The made-for-cable documentary film The Real Eve is predicated on the theory that the human race can be traced to a common ancestor. The mitochondrial DNA of one prehistoric woman, who lived in Africa, has according to this theory been passed down from generation to generation over a span of 150,000 years, supplying the "chemical energy" to all humankind.
