Perched atop a mountain crest, mysteriously abandoned more than four centuries ago, Machu Picchu is the most famous archeological ruin in the Western hemisphere and an iconic symbol of the power and engineering prowess of the Inca.
How do you get a genius brain? Is it all in your DNA? Or is it hard work? Is it possible that everyone’s brain has untapped genius — just waiting for the right circumstances so it can be unleashed? From a man who suddenly acquired an extraordinary musical gift after a freak head injury to a “memory athlete” who can remember strings of hundreds of random numbers, David Pogue meets people stretching the boundaries of what the human mind can do in NOVA scienceNOW: How Smart Can We Get?
There is a startling gap between the glamorous television world of “CSI” and the gritty reality of the forensic crime lab. With few established scientific standards, no central oversight, and poor regulation of examiners, forensics in the U.S. is in a state of crisis.

Mark Evans and Joy Reidenberg brave the baking desert to dissect a camel, the ultimate desert survivor. They uncover the secret of the camel’s hump and investigate how its elastic legs, stretchy lips and pedestal (a strange bump on its chest) are among the many surprising adaptations that enable the camel to thrive in such a dry and hostile environment.
They slice through the water’s surface with explosive power — sail, spear and half a ton of muscle flashing in the sun. Their journeys through the open ocean are epic, their life cycle, bizarre. They are the billfish — marlin, sailfish, spearfish and swordfish — largest and most highly prized of all gamefish.
Investigate the parallel stories of collapsing Pacific salmon populations and how biologists and engineers have become instruments in audacious experiments to replicate every stage of the fish’s life cycle in Nature “Salmon: Running the Gauntlet.”
