Yesterday Spark unveiled Kupu - a smartphone app which you can use to take photos of everyday things.

Using Te Aka Māori Dictionary data, the app analyses the image and tells you its name in te reo.

Dr Dean Mahuta was involved with the app's development and tells us a bit more about it.

1:25 The Secret Life of Girls

What do young girls like to do? How do they see themselves in the world? These are the questions being answered in a new documentary series. 

As part of the Suffrage 125 initiative, TVNZ's The Secret Life of Girls follows a group of five-year-old girls at an Auckland kindy as they interact and complete tasks through the day. 

Psychologist Dr Annette Henderson provides commentary on the science behind the girls decisions, and she joins us now to tell us about the show.

2:20 Music Feature - National Anthems

Whether they're calling for divine protection, bragging about the colour of a country's soil, or calling for citizens to rise up against the bourgeoisie, national anthems are a big part of many countries' collective identities.

Professor Anthony Ritchie from Otago University arranged all 20 national anthems for the 2011 Rugby World Cup.

He joins us to talk about anthemic styles, regional differences, and the best and worst anthems to sing.

36 questions. That's all it takes to turn a stranger into something more.  That plus four minutes of sustained eye contact can help two people become more intimate and potentially fall in love according to professor Arthur Aron of Stony Brook University in New York.  

He's creating love in the lab and shares his insights into how to develop strong connections with other people and how to keep them strong.
