The question being asked in this film is - "Are people, in an effort to outwit raccoons, actually making them smarter and unwittingly contributing to their evolutionary success?" Are the ever more complex obstacles that our fast-paced, urban world throws at them actually pushing the development of raccoon brains?

Modern humans have been around for some 200,000 years, which is peanuts compared to some of the species alive today: there are creatures that have been with us since the Cambrian age and trees that have barely changed in the last 300,000 years. Natural history palaeontologist Richard Fortey investigates why certain life forms endure..

What happens to nature after a nuclear accident? And how does wildlife deal with the world it inherits after human inhabitants have fled?In 1986 a nuclear meltdown at the infamous Chernobyl power plant in present-day Ukraine left miles of land in radioactive ruins. Residents living in areas most contaminated by the disaster were evacuated and relocated by government order, and a no-man’s land of our own making was left to its own devices. In the ensuing 25 years, forests, marshes, fields and rivers reclaimed the land, reversing the effects of hundreds of years of human development. And surprisingly, this exclusion zone, or “dead zone,” has become a kind of post-nuclear Eden, populated by beaver and bison, horses and birds, fish and falcons – and ruled by wolves.Access to the zone is now permitted, at least on a limited basis, and scientists are monitoring the surviving wildlife in the area, trying to learn how the various species are coping with the invisible blight of radiation. As the top predators in this new wilderness, wolves best reflect the condition of the entire ecosystem because if the wolves are doing well, the populations of their prey must also be doing well. Accordingly, a key long-term study of the wolves has been initiated to determine their health, their range, and their numbers.Radioactive Wolves examines the state of wildlife populations in Chernobyl’s exclusion zone, an area that, to this day, remains too radioactive for human habitation.

This is the incredible story of Trishna and Krishna, twin girls born joined at the head. Abandoned shortly after birth at an orphanage in Bangladesh, they had little chance of survival until they were saved and taken to Australia by an aid worker.After two years battling for life, the twins were ready for a series of delicate operations which would prepare them for the ultimate challenge: a marathon separation surgery that will allow them to live truly separate lives. From the very beginning, surgeons knew there was no guarantee of survival for either of the girls--but without surgery there was no hope at all.
