Episode Information

It’s an unknown planet, yet it seems strangely familiar: deep canyons and crevices scar the land- scape, rugged mountain ranges tower over vast plains, humid jungles and acidic lakes hide creatures unknown to most—ferocious predators, peaceful grazers, cunning quick-change artists. But this alien planet is not from outer space. This planet is you. At any given moment, we are the human habitat of 100 trillion organisms, almost all of them hidden from our naked eye. The average human plays host to four pounds of alien creatures that inhabit every nook and cranny of our body. Scientists are just beginning to understand the real dimensions of this biodiversity. This extraordinary 3D-adventure takes us on a journey into an inner world few of us are aware of. Specially developed electron microscope imaging reveals the dramatic interactions happening in our body tissues when microbes, parasites, cells and viruses ght and co-operate. We will combine images from the latest scanning electron microscopes with CGI to y over micro-landscapes, travel through cells and organs as we explore what makes this amazing eco-system work.
