But most fascinating of all is seeing how Professor David Scheel and his daughter Laurel bond with an animal that has nine brains, three hearts and blue blood running through its veins.

In this documentary, scientists reveal their findings on the influence of solar storms on animal behavior and human transport infrastructure.

Recorded by pioneers as far back as 1805, the Tasmanian tiger has become an intensely mystifying Australian icon, whose entire existence has become the stuff of both fable and legend. This program investigates a chequered past and puts the speculation into perspective, taking into account the tragic culling and ‘bounty era’ where the carnivorous creatures were thought to be solely responsible for a considerable loss of farmers’ livestock. Balancing the facts with personal reflections from Tasmanian locals, scientists and other informed practitioners, The Tasmanian Tiger is a thought-provoking and revealing look at the extraordinary life and death of one of Australia’s most mysterious marsupials.

Animals have been consuming plants, fruits, and mushrooms that sometimes get them high for much longer than we humans have.

In the Faroe Islands, a team of biologists is studying these marine plants with the aim of improving salmon farming and avoiding the need for drugs or chemicals. In Munich, others are working on a tiny algae whose high oil content could eventually replace petroleum. The carbon fiber obtained from it is a real match for fossil fuels. In France, a tower resembling a Morris column is being used to purify the air. The tower absorbs one tonne of CO₂ per year - the equivalent of several dozen trees - and converts it into oxygen.
