The film discusses the evolution and potential of using light waves, particularly coherent light, for communication. It highlights the development of lasers at Bell Telephone Laboratories, explaining how they produce a highly controlled and intense beam of light that could revolutionize communication. The film emphasizes the vast possibilities of lasers, including applications in telecommunications, surgery, and exploring the universe, suggesting that this technology represents a significant step in humanity's understanding and use of light.

Dr. Helen Caldicott is the most prominent anti-nuclear activist in the world. She's been featured on CNN, 60 Minutes, CBC and Democracy Now. In the 80s, Helen Caldicott campaigned against nuclear weapons testing in the pacific (still responsible today for the majority of tritium we're exposed to), and against the notion of a winnable nuclear war. She was nominated for a Nobel Peace Prize for her efforts. She has always made inaccurate statements regarding civilian nuclear power. But, since the Fukushima-Diachii radiation release has caused (and is projected to cause) zero fatalities... http://www.unis.unvienna.org/unis/en/... ...her tone has changed when speaking to supporters. This has not been acknowledged by prime-time media, as they continue to use her as a source. Any person or media outlet should check Caldicott's history of statements (on any subject) against a domain expert before using her as a source.

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.

Before the joint NASA/ESA Cassini-Huygens mission, humanity only knew what had been learned, decades earlier, with the previous limited, rapid "fly-by" Pioneer and Voyager missions. Cassini-Huygens spent more than 13 years in wildly varied orbits around Saturn, allowing the spacecraft to pass near many of its moons, as well as execute a soft-landing of its Huygens lander on the moon Titan. By mission end, it accumulated a mountain of imagery and scientific data that will continue to be studied for years to come. This film is a testament to the amazing efforts of the scientists who planned and executed the mission. It combines breathtaking images, movies, and a variety of animations to take the viewer into Saturn's complex system of rings and moons, as well as stepping viewers through some of the more exciting scientific discoveries made over the course of the elaborately complex mission.

The discovery of neuroplasticity, the fact that thoughts can change the structure and function of our brains, even into old age, is one of the most important breakthroughs in our understanding of the brain in recent times. In The Brain That Changes Itself, Dr Norman Doidge explores the profound implications of the changing brain in a way that will permanently alter the way we look at human possibility and human nature. The documentary examines a blind man who sinks a basketball; a woman with half a brain who leads a normal life; learning disorders, strokes and brain traumas that are improved and cured; and chronic pain that is alleviated. The vast expanse of the brain's possibility is still unrealized.

They have no roots, no seeds, no flowers, but mosses show immense survival capacities and can suspend their biological activity for long periods. Today, researchers are exploring the exceptional resistance of these archaic organisms. British ecologists have even resurrected a "zombie" moss that has been trapped in the permafrost for 1,500 years. Associated with decay and disliked in Europe, mosses are deified in Japan. With 25,000 species worldwide, bryophytes - their scientific name - are the seat of real ecosystems, and can develop in inhospitable landscapes, through an extravagant reproduction cycle.
