Earlier this month the Dunedin Study into health and behaviour marked its 50th birthday.

In 1972, a researcher in the city set out to track the development of more than 1,000 newborn babies up to the age of three.

Little did Phil Silva realise that over the next 50 years, his research would morph into one of the world’s most important longitudinal studies - the subsequent work yielding more than 1,300 peer-reviewed research papers, reports, and books.

Terrie E. Moffitt, Ph.D. Nannerl O. Keohane University Professor of Psychology at Duke University, and Associate Director of the Dunedin Study joined Jonathan to discuss.

Dr. Shane Bergin & Dr. Lara Dungan also joined Jonathan to run through the week's science news in Newsround.
