Meet two winners of the 2023 Prime Ministers Science Prizes. In the wake of the 2019 Whakaari eruption, Professor Ben Kennedy engaged communities with the science of volcano hazards – mahi that earns him the 2023 Science Communication Prize. Meanwhile, Future Scientist prizewinner 17-year-old Sunny Perry has developed a helpful soil map.

Kate Evans visits a passionate team as they carpet a remote volcanic island in Tonga with poisoned bait, hoping to eradicate rats. What does it take to complete this kind of project, what are the chances of success, and what will it mean for the island’s ecosystems if they manage to remove the rats once and for all?

Turning the tide – what it takes to take out rats

Journalist Rebekah White meets two people who have been counting albatrosses on remote islands in the subantarctic for more than three decades. Their research shows that at least one species is en route to extinction. A few changes to the way we fish could save it.
