On This Week's Programme

Science

The filmmaking talents of three Otago Girls High School students have earned them a trip to Greenland. Peggy Russell, Annika Metua and Susan Smirk are the winners of this year's Freemasons Big Science Adventures competition. They share experiences from their recent travels, and lessons they've brought back for New Zealanders.

Environment

Details of a national emissions trading scheme for New Zealand were released this week. To help provide context for the announcement, we take a look at the world's first mandatory carbon trading scheme, launched in New South Wales in 2003. Dacia Herbulock talks to Scheme Administrator Christopher Spangaro and Anthea Harris of Australia's National Emissions Trading Taskforce about some of the challenges faced when designing a working scheme.

New Zealand relies heavily on its tourism industry, and its "clean, green" reputation. But how much does concern for the environment influence the booking choices of the average tourist? Amelia Nurse sat down with Christian Schott, lecturer in tourism management at Victoria University of Wellington, to find out what sustainable tourism is and how "ecolabels" work.

Health

We're all familiar with X-rays - those fuzzy black and white images clipped to a lightbox. The European Organisation for Nuclear Research, or CERN has developed a new standard in X-ray technology, using a computer chip called Medipix. Louise Wallace talks to Philip Butler, a physicist at the University of Canterbury, and his son Anthony Butler, a technical director - also at Canterbury, to find out what this new technology means.
