This week on the Tuesday Wire...

For Dear Science this week, we’re doing things a little differently, with two new experts, Professor Sebastian Leuzinger and Associate Professor Armagan Sabetian, chat with us about Octopus brains and fast-aging fish.

Host Alex speaks with Professor in the Faculty of Law at the University of Otago, Andrew Geddis, about New Zealand First’s promise to restrict voting rights for non-citizens.

Producer Liam chats with Associate Professor Jennifer Frost from the University of Auckland about America’s 250th Anniversary, how people have engaged with it, and how President Donald Trump is increasingly modelling himself as a king and distancing himself from the principals that founded the United States. 

Liam also speaks to Dr John Horrocks, an independent researcher, about the continued use of leaded petrol in New Zealand for light aircraft and motor racing, the possible health consequences of the use of leaded petrol, and what this country can do to phase it out completely.
