What will getting KiwiRail's operations away from diesel and onto renewable sources mean for jobs, the regions and the environment ? Kiwirail had planned to scrap the electric trains by April next year but now the government has announced it will spend 35-million dollars over the next four years refurbishing 15 electric trains, extending their life by 10 years. Kathryn talks to the Rail and Maritime Transport Union general secretary, Wayne Butson and Dr Roger Blackley from Greater Wellington Regional Council who is a former Secretary for the Environment, an Engineering New Zealand Distinguished Fellow.

09:15 Research into distressing dental condition

Chalky teeth, or more technically, Molar-Incisor Hypomineralisation is when the enamel on the 6 year old molars does not form properly. When the teeth erupt they are brown and can crumble leading to pain, distress and often extraction. Research into the condition which affects one in six children globally has been patchy and the cause or causes are still not understood. Dorothy Boyd is a paediatric dentist at Otago Dental School who has researched chalky teeth. She joins Kathryn along with Professor Mike Hubbard who is a New Zealander leading a world wide campaign to get more research funding so dentists can better understand what causes chalky teeth and how to prevent it.
