Alaska Gold

Bristol Bay in southwest Alaska is home to the last great wild sockeye salmon fishery, and to mineral deposits estimated to be worth nearly $500 billion. probes the fault lines of a growing battle between those who depend on this extraordinary fishery for a living, the mining companies pushing to extract the minerals and the political framework that will ultimately decide the outcome.

Mars: Dead or Alive - PBS Nova

On January 3, 2004, a strange sight unfolded on the planet Mars. Above a vast, dry lake bed south of the martian equator, a conical vehicle parachuted toward the surface. Then, just before touch down, it was enveloped by a gigantic protective airbag allowing the craft to bounce safely to a stop. Inside was Spirit, the most sophisticated rover ever launched from Earth. "MARS Dead or Alive," which originally aired just hours after Spirit landed on the red planet, covers this mission in depth.

The program's behind-the-scenes look at the construction of Spirit and its twin, Opportunity, includes a special up-to-the-minute segment with the latest news from Mars as of January 3, 2004—to learn if Spirit is ready to undertake the most comprehensive search for evidence of liquid water ever attempted on Mars.



NOVA spent months documenting the tension-filled process of building, testing, final checkout, and launch of a pair of spacecraft that are designed not only to be remote-controlled field geologists but to perform in a demanding environment millions of miles from Earth. As the program shows, unexpected problems with designs for the parachute and airbags almost scuttled the mission, and a potentially catastrophic electronic problem on Spirit didn't turn up until the vehicle was completely inaccessible and awaiting launch.

Riding on the mission are not just the hopes of scientists seeking to answer baffling questions about the history of Mars, but the future of NASA's Mars exploration program itself. Twice in 1999 NASA probes arriving at Mars were lost without a trace. One of the few recent bright spots for Mars research was the surprising success of the experimental lander-rover Pathfinder in 1997, which was designed to test the airbag-landing technique.

Pathfinder was spawned by a freewheeling group of young scientists and engineers who are now back with the far more ambitious Spirit and Opportunity vehicles, which make up what is officially called the Mars Exploration Rover (MER) project. The MER science team is headed by planetary scientist Stephen Squyres of Cornell University, who conceived the project with the goal of probing the most burning questions in Mars science: Was there ever liquid water on the Red Planet? Were conditions ever suitable for life?

Spirit and Opportunity are mobile laboratories outfitted with visible-light and infrared cameras to scan the landscape and locate promising rocks for investigation; a power tool to grind off the weathered surface; a microscope to examine the interior; and two other instruments to sniff out the rock's chemistry. (For a closer look at a MER, see Anatomy of a Rover.) In this way, the MER team held out hope of finding evidence of the liquid water that many scientists theorize was once abundant on Mars's surface but has since vanished.

The landing sites were chosen for their strong signs of a wet past. Spirit is now on site in Gusev Crater, a possible former lake, while Opportunity has been exploring Meridiani Planum, where minerals have been detected that normally form in the presence of water. And where there's water, there may have been life. The ultimate goal of Spirit and Opportunity is to shed light on this intriguing possibility and perhaps pave the way for the most versatile explorers of all—humans.

The Mind's Big Bang

Fifty thousand years ago, something happened, the modern human mind emerged, triggering a creative, technological, and social explosion. What forces contributed to that breakthrough? Where might our power of mind ultimately lead us? Evolution determines who lives, who dies, and who passes traits on to the next generation. The process plays a critical role in our daily lives, yet it is one of the most overlooked and misunderstood concepts ever described. The Evolution series goals are to heighten public understanding of evolution and how it works, to dispel common misunderstandings about the process.



The Evolution project's eight-hour television miniseries travels the world to examine evolutionary science and the profound effect it has had on society and culture. From the genius and torment of Charles Darwin to the scientific revolution that spawned the tree of life, from the power of sex to drive evolutionary change to the importance of mass extinctions in the birth of new species, the Evolution series brings this fascinating process to life. The series also explores the emergence of consciousness, the origin and success of humans, and the perceived conflict between science and religion in understanding life on Earth.

Evolutionary Transformations

What underlies the incredible diversity of life on Earth? How have complex life forms evolved? The journey from water to land, the return of land mammals to the sea, and the emergence of humans all suggest that creatures past and present are members of a single tree of life.

The Human Spark: So Human So Chimp

We are separated from our nearest relatives, the chimpanzees, by only one or two percent of our genes -- but also by some 6 million years of going our different evolutionary ways. So when we meet the eyes of a chimp we are reminded uncannily -- and perhaps a little uneasily -- of ourselves.

Part 1/4



But we are also aware that behind those eyes is a mind very different from our own. Alan Alda sets out to explore that difference, and quickly finds that the scientists studying chimps and other non-human primates are themselves separated into opposing worldviews. One camp emphasizes the continuity between us -- seeing everything we believe to be uniquely human present in at least a rudimentary form in our ape and even monkey cousins. The other camp sees a sharp discontinuity in our abilities, admiring chimps for their superb adaptation to their (rapidly disappearing) forest environment, but also granting to human minds a special status that has enabled us to conquer the planet (and cause those forests to disappear).

Part 2/4


What is the nature of human uniqueness? Where did "The Human Spark" ignite, and when? And perhaps most tantalizingly, why? In this three-part series, Alan Alda takes these questions personally, visiting with dozens of scientists on three continents, and participating directly in many experiments -- including the detailed examination of his own brain. Bringing his trademark humor and curiosity to face-to-face conversations with leading researchers, he seeks "The Human Spark" -- from archaeologists finding clues in the fossilized bones and tools of our ancestors; to primatologists studying our nearest living relatives to explore what we have in common and what sets us apart; to neuroscientists peering into his mind with the latest brain scanning technologies.

The Human Spark: Becoming Us

In the caves and rock shelters of the Dordogne region of France, Alan Alda witnesses the spectacular paintings and carvings that date back some 30,000 years, artwork that archeologists once thought to be the first record of people with minds like our own. When this art was created, Europe had already been peopled for hundreds of thousands of years -- and thousands of lifetimes -- by humans we call Neanderthals.

Part 1/4



Alan Alda discovers, from visits to sites where Neanderthals once lived, that Neanderthals were tenacious and resourceful. But they appear to have lived in and of the moment; certainly they produced no art, and employed a stone tool technology that changed little over millennia. The people who painted the caves, our ancestors, were strikingly different, possessed of what we are calling the Human Spark, capable not only of art but of innovative technology and symbolic communication. The questions Alan explores: Where and when did the Human Spark first ignite? In these caves, as archeologists have long believed? Or at a much earlier time -- and on another continent?

Journey Of Man A Genetic Odyssey

Where did we come from? Spencer Wells, a 33 year old population geneticist, has closed the door on his laboratory and is embarking on the biggest adventure of his life. His mission to retrace the most extraordinary journey of all time, a journey that involves every man, woman and child alive today. He offers his thoughts on this puzzling question, employing the latest in DNA research and technology to track the migration of humanity across the globe.



By collecting blood samples from thousands of men living in isolated tribes around the world and analyzing their DNA, Spencer and his colleagues discovered that all humans alive today can be traced back to a small tribe of hunter-gatherers who lived in Africa 60,000 years ago. Following this genetic trail, Spencer has charted the ancient journey of our ancestors as they populated the planet.

Spencer scours the world for indigenous people with deep roots in one place, asking for samples of DNA to test, in order to piece together our "big family" genetic tree. In Indiana Jones mode, Wells tacks down common ancestors and comes up with some surprising candidates. He shows with DNA results the diverse ways in which people and tribes react to the news of what science says about their arrival and relations. View this as adventure travel or as a painless way to begin your genetic literacy.

PBS Evolution - Why Sex ?

In evolutionary terms, sex is more important than life itself. Sex fuels evolutionary change by adding variation to the gene pool. The powerful urge to pass our genes on to the next generation has likely changed the face of human culture in ways we're only beginning to understand.
