1:15 Can vitamin C help in treating cancer and other infections?

Vitamin C is useful for a whole lot of things beyond staving off scurvy - but it's not a panacea for all your ills, either.

Academics from around the world are gathering in Christchurch this evening to share the latest research into vitamin C and its effectiveness as a tool to treat cancer and other infections, and to boost immunity.

Otago University professor Margreet Vissers will be at the session, and joins us to explain what the science says so far.

Last year we spoke to one of the Otago University team trialing the use of intravenous high dose Vitamin C for patients with sepsis.

1:25 The sea cucumber, ocean hitch-hiker extraordinaire

Sea cucumber meat is a big industry overseas, but the location and supply of cucumbers varies wildly from year to year, mystifying researchers and those trying to make a living off them.

But Canadian academic Annie Mercier thinks she's figured out why: and it's all to do with ocean currents, and hitching a ride.

Dr Mercier joins us to explain her findings.

3:30 The New Zealand history wars

Our regular historian, Grant Morris from Victoria University talks about the current debate in NZ around whether our colonial history should be compulsory in schools. He says this is a complex issue as when we talk about teaching NZ history we should also ask the question 'whose NZ history?' 

The Treaty of Waitangi. He Tohu, a new permanent exhibition of three iconic constitutional documents that shape Aotearoa New Zealand. Treaty of Waitangi, Declaration of Independence and Women's Suffrage Petition.
