Why Do We Dream

   2009    Medicine
Horizon uncovers the secret world of our dreams. In a series of cutting-edge experiments and personal stories, we go in search of the science behind this most enduring mystery and ask: where do dreams come from? Do they have meaning? And ultimately, why do we dream? What the film reveals is that much of what we thought we knew no longer stands true. Dreams are not simply wild imaginings but play a significant part in all our lives as they have an impact on our memories, the ability to learn, and our mental health. Most surprisingly, we find nightmares, too, are beneficial and may even explain the survival of our species.

Snake Killers Honey Badgers of The Kalahari

   2007    Nature
The honey badger looks like something you might buy in pet shop and give to children, but turns out to be one of the most violent and determined creatures ever to scuttle across the face of the earth. Nothing in the badger’s world-not even the badgers themselves-are safe from its remarkable ability to create havoc and cause harm. Like a meter long skunk with the brain of a shark the Honey Badger’s metabolism compels it to eat constantly and live on the run. Its diet is admirably inclusive ranging from insects to its own young. If an animal is too big to eat then the badger will fight it anyway, indeed it is this almost supernatural tenacity that compels you respect it, as well as yielding some of the most spectacular sequences in the film. Five foot long cobra sleeping in the top of tree? No problem, the badger scoots up and bites its head off. When an ailing badger is attacked by a full size leopard it takes the leopard over an hour to finish it off. When one is bitten in the face by a snake that can kill a man, it just lies down for a while and sleeps it off.

The Persistence of Memory

   1980    Science
The idea of intelligence is explored in the concepts of computers (using bits as their basic units of information), whales (in their songs and their disruptions by human activities), DNA, the human brain (the evolution of the brain stem, frontal lobes, neurons, cerebral hemispheres, and corpus callosum under the Triune Brain Model), and man-made structures for collective intelligence (cities, libraries, books, computers, and satellites). The episode ends with speculation on alien intelligence and the information conveyed on the Voyager Golden Record.
