7:12 New Zealand Native Fish - Potamopyrgus Snails

If you have spent any time in any river or stream you have probably seen these little guys. Tiny dark brown turrets clinging to the stones in the shallow water, or carving little pathways through the mud, lovingly licking up algae and debris. Stella McQueen joins us to tell us more.

8:30 Window on the World

Hossein Sharif is an Iranian boy, about to marry Hee Sue, a South Korean girl. 

As the families begin to meet, Sharif discovers all the criss-crossing roads that the couple's home countries have travelled. In the last 50 years, South Korea and Iran have switched places in the world table of economic prosperity. 

South Korea has risen while Iran has fallen behind. Hossein and Hee Sue's families begin to discover a parallel universe, a world of "might have beens" and divergent paths.  

9:07 White Silence

Our last episode of White Silence: It's been 40 years since 257 people died in a plane crash on the icy slopes of Mt Erebus ín Antarctica. Yet there is still no national memorial to the victims and no real consensus on what happened that day. This RNZ/Stuff collaboration asks: why has New Zealand been so unable to deal with its worst ever disaster?

White Silence is a podcast from Stuff and RNZ on the Erebus disaster, Air New Zealand's darkest hour.
