Are we becoming Plastic People? Our ground-breaking feature documentary investigates our addiction to plastic and the growing threat of microplastics on human health. Almost every bit of plastic ever made ends up ground down into "microplastics". These microscopic particles drift in the air, float in the water and sit in the soil. And now, leading scientists are finding them in our bodies: organs, blood, brain tissue and even the placentas of new mothers. What is the impact of these invisible invaders on our health? Ziya Tong, author and science journalist, makes it personal by visiting leading scientists and undergoing experiments in her home, on her food, and on her body.

An exciting video journey through the world of time-lapse photography by one of the founders of the science of photobiology, Dr. John Nash Ott. Do fluorescent lights cause cancer and childhood learning and behavior disorders? Can long-term exposure to low-level radiation as from TV sets, computers, fluorescent lights, and similar devices harm you? Does living behind window glass and with glasses covering our eyes over years affect our health? Is natural sunlight and trace ultra-violet radiation really harmful? Or is it necessary and beneficial? How do cells, plants, and animals respond to constant exposure to different light color frequencies? These and similar questions were the subjects of Dr. Ott's pioneering investigations in the field of photobiology, using the methods of time-lapse photography.

In 1973 Yorkshire public television made a short film of the Nobel laureate while he was there. The resulting film, Take the World from Another Point of View, was broadcast in America as part of the PBS Nova series. The documentary features a fascinating interview, but what sets it apart from other films on Feynman is the inclusion of a lively conversation he had with the eminent British astrophysicist Fred Hoyle.

In this two-part Channel 4 series, Professor Richard Dawkins challenges what he describes as 'a process of non-thinking called faith'. He describes his astonishment that, at the start of the 21st century, religious faith is gaining ground in the face of rational, scientific truth. Science, based on scepticism, investigation and evidence, must continuously test its own concepts and claims. Faith, by definition, defies evidence: it is untested and unshakeable, and is therefore in direct contradiction with science. In addition, though religions preach morality, peace and hope, in fact, says Dawkins, they bring intolerance, violence and destruction. The growth of extreme fundamentalism in so many religions across the world not only endangers humanity but, he argues, is in conflict with the trend over thousands of years of history for humanity to progress to become more enlightened and more tolerant.
