09:05 Mobile dental clinics pulled out of service amid fears of toxic exposure

Mobile dental clinics around the country have been pulled from service for testing after high levels of formaldehyde were found in some Canterbury Clinics.  
The clinics provide dental care for tens of thousands of primary school children around New Zealand. The Canterbury District Health Board conducted tests and found formaldehyde levels three times national health standards. It then alerted other DHB's around the country which have begun their own testing, and several have followed suit by taking mobile clinics out of service.

Janice Gemmel is the organiser for the National Union of Public Employees - NUPE - which represents many Canterbury dental staff.

Jason Padgett (right) has acquired savant syndrome – he became a mathematical genius after a vicious assault 12 years ago. Prior to being brutally attacked he had no aptitude for maths, but when he recovered from his injuries he began seeing the world very differently and drew what he was seeing. A physicist saw his drawings and helped him get traditional mathematics training to be able to describe in equations the complex geometry of his drawings. Jason Padgett's book is Struck by Genius: How a Brain Injury Made Me a Mathematical Marvel.
