Mind reading might sound like pseudoscientific, but its scientific counterpart, thought identification, is very much a real thing. It's based in neuroimaging and machine learning, and what's really cool is that experiments in mind reading aren't just about spying on what someone is thinking. They're about figuring out what thoughts are even made of.
When you think of something, what does that mental picture actually look like? What resolution is it in? How high fidelity is a memory, and how do they change over time? In this episode, we are going to look at how reading people's minds can help us answer these questions.

Eternal life is humanity’s oldest dream. It may be finally coming true. Today, at least in the West, the quest for immortality has shifted from the metaphysical to the technical and the scientific. In this film we will investigate the advancement of this research in laboratories around the world. With cryonics technology improving, human cloning now possible, mind uploading and digital brain simulation thriving, reversing the aging of cells and organs feasible, immortality may seem right around the corner. In some countries, such as the US, Russia and Europe, private companies are financing and promoting the promise of immortality or at least a longer life expectancy. Are they selling a reality or utopia? We will meet scientists, neurophysiologists, computer specialists, geneticists, and biologists, and also hopefuls of immortal life, futurists, sociologists and businessmen. We will film different research laboratories and cities built for the aging; we will interview the experts as well as the anonymous men and women who speak about their relationship with life and death and those who simply embody it.

Helen Czerski ventures beyond the visible spectrum in the final (and best) episode in this vibrant series, showing how electromagnetic radiation is so much broader than the narrow slice of reality we see with our eyes. Before delving into the details of UV, infrared and x-rays, Dr Czerski explores colour subjectivity by trying on a dress that recently divided the internet — to some it appeared blue and black, to others white and gold. It's a perfect fit. It's also a neat analogy of how people can have opposing views but both swear blind that their perspective is correct. The series ends with some amazing imaging techniques that show our bodies in a whole new light.

Rivers provide the essentials of life: fresh food and water. They often provide natural highways and enable us to live in just about every environment on Earth.

There's also a look at the remarkable partnership between Samburu tribesmen and wild elephants in their search for water in the dried-out river beds of Northern Kenya. Plus, a father who must take his two children on a six-day trek down a frozen river - the most dangerous school run on Earth, and the ice dam busters of Ottowa with their dynamite solution to a city centre hold-up.

In the fourth episode of the series, eyewitnesses recall how those in power at Auschwitz lined their pockets with wealth stolen from Jewish inmates while also engaging in illicit affairs.
