Svalbard in the Arctic spends many months of the year in complete darkness, an unrelenting frozen winter with temperatures down to -40 Celsius. But when the sun finally reappears, the landscape magically transforms from an ice world into a rich tundra, full of exotic plants, birds, arctic foxes, polar bears, walrus and reindeer. This film captures the changes in all their glory and reveals how this transformation is only possible thanks to some bizarre micro-organisms that feed on ice and the stunning abilities of migrating birds.
From earthquakes to tsunamis to volcanic eruptions, natural disasters are both terrifying and fascinating - providing endless fresh material for documentary makers. But how well do disaster documentaries keep pace with the scientific theories that advance every day? To try and answer that question, Professor Danielle George is plunging into five decades of BBC archive. What she uncovers provides an extraordinary insight into one of the fastest moving branches of knowledge. From the legendary loss of Atlantis to the eruption that destroyed Pompeii, Danielle reveals how film-makers have changed their approach again and again in the light of new scientific theories. While we rarely associate Britain with major natural disaster, at the end of the programme Danielle brings us close to home, exploring programmes which suggest that 400 years ago Britain was hit by a tidal wave that killed hundreds of people, and that an even bigger tsunami could threaten us again.
Professor David Scheel takes an octopus into his home to learn about its intelligence and the extraordinary relationship he and his daughter develop with the creature. Named Heidi, the octopus is seen unravelling puzzles, recognising individual humans and even watching TV with the family. The film also looks at the remarkable behaviour of other octopuses around the world, from those that can change their colour and texture in a split second to the octopus that carries around its own coconut shell to hide in.
The Serengeti is one of the most biologically diverse areas on earth--but it's also the scene of some of the most important fossil discoveries ever made. Join us as we meet the modern inhabitants of this ancient land, and track how their evolution helped shape our understanding of human origins.
