Sniper: Bulletproof deconstructs and analyzes the little-known sniper events that have occurred when no other course of action was possible. The people who planned the takedowns, or pulled the trigger, share their techniques and bring to light the many factors that had to be considered in each mission: terrain, wind speed, temperature, elevation changes... all are critical to taking out targets considered bulletproof. A sniper has one chance, one breath, to rise to the occasion and save the day... if they miss, there may never be another opportunity. As these never told before stories unfold, the viewer also learns about the high-tech gear each sniper carries on their classified missions.

In 1962, spurred by the Cold War, President John F. Kennedy famously made the bold proclamation that NASA would send astronauts to the moon by the end of the decade, not because it was easy, but because it was a challenge. The Space Race inspired a generation to pursue careers in science and technology, but as the balance of world power shifted, interest in space exploration declined. "Fight for Space" serves as an urgent call to re-awaken our sense of wonder and discovery.

As society tackles the problem of feeding our expanding population safely and sustainably, a schism has arisen between scientists and consumers, motivated by fear and distrust. Food Evolution, narrated by Neil deGrasse Tyson, explores the polarized debate surrounding GMOs. Looking at the real-world application of food science in the past and present, the film argues for sound science and open-mindedness in a culture that increasingly shows resistance to both.

Trees talk, know family ties and care for their young? Is this too fantastic to be true? German forester Peter Wohlleben and scientist Suzanne Simard have been observing and investigating the communication between trees over decades. And their findings are most astounding.

A feature documentary about the journey of mankind to discover our true force and who we truly are. It is a quest through science and consciousness, individual and planetary, exploring our relationships with ourselves, the world around us and the universe as a whole.

Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.

Of the Seven Wonders of the Ancient World, the Pyramid is the only one to survive. Many believe that even with our 21st-century technology, we could not build anything like it today. Based on the most up-to-date research and the latest archaeological discoveries, here is how the Pyramid came to be.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

Principles of Curiosity presents a general introduction to the foundations of scientific skepticism and critical thinking, focusing on a simple process we call the three Cs.
