Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.

It starts with a chat to a mysterious stranger at a beach bar in Mexico - and leads to a big case of mistaken identity thanks to a fedora with a faded pink feather. Kiwi Nick Davies has just released a new book, a piece of sunset noir, set in the dangerous world of Latin-American espionage. His lead character, Lou Galloway, is a failed actor who ends up having to nail the role of a lifetime - because his life depends on it.

The latest IPCC report warns the world is likely to have warmed by 1.5 Celcius by the time the next report is released in 2030. While climate officials warn how far off-track we are, the report concludes it's not too late to tackle climate change if swift action is taken and funding is ramped up. A summary report of thousands of pages of findings from the world's leading climate scientists, including from New Zealand, says there are "multiple, feasible and effective options" to avert climate disaster. Kathryn speaks with the Guardian's Environment Correspondent, Fiona Harvey.

Kathryn speaks to former Royal College of GPs medical director, now Chair of General Practice New Zealand Bryan Betty about the pressure doctors can come under from patients over access to the drugs.
