World Book Club - Michelle de Kretser: Scary Monsters

Harriett Gilbert talks with Michelle de Kretser about her eighth novel, Scary Monsters, which won the 2023 Rathbones Folio Fiction Prize.

This diptych novel consists of the tale of two immigrants, one in the past, and one in a dystopian future that seems all too possible. Which story to start with? That’s the reader’s decision.

In the past, Lili. Her family migrated to Australia from Asia when she was a child. Now, in the 1980s, she teaches in Montpellier, in the south of France. Her life revolves around her desires to carve out a space for herself, and become a great woman like Simone de Beauvoir. She tries to make friends, observes the treatment of other immigrants to France who don’t have the shield of an Australian passport, and continually has to dodge her creepy downstairs neighbour, as stories of serial killers dominate news headlines.

In the future, Lyle works for a government department in near-future Australia where Islam has been banned, a pandemic has only recently passed, and the elderly are encouraged to take advantage of The Amendment - a law that allows, if not encourages, assisted suicide. An Asian migrant, Lyle is terrified of repatriation and spends all his energy on embracing "Australian values", which in this future involve rampant consumerism, an obsession with the real estate market, and never mentioning the environmental catastrophe even as wildfires choke the air with a permanent smoke cloud. He's also preoccupied by his callously ambitious wife, his rebellious children and his elderly mother who refuses to capitulate to his desperate desire to invisibly blend in with society.

We love it, not just because of the playful dual structure, but because Michelle’s writing tackles the monsters - racism, misogyny, ageism - with keen observations and biting humour, shining a light not just on how society treats newcomers, but how we relate to our idea of our shared history, and what kind of future will be built from the world we live in now.

CrowdScience - How do you measure a mountain?

On the banks of the St Lawrence River in Quebec stands a 100-year-old lighthouse. While initially built to help boats navigate one of Canada’s most difficult waterways, the Point-de-Père site now also holds a different responsibility: it is a key reference for measuring sea levels around the entire North America continent.

But this is all set to change. With the development of new satellite technology, the tricky task of measuring sea levels is being updated - which could mean mountains around North America get brand new official heights.

In this episode we revisit a question from CrowdScience listener Beth, who wondered about the elevation signs she saw scattered along a mountainous road, indicating how high above sea level she was. As sea levels rise, will all the elevation signs need repainting? And how do you measure sea level, anyway?

The height of an enormous pile of rock like Ben Nevis, or Mount Everest feels unchangeable. But we measure them relative to the nearest patch of sea, which is where our story becomes complicated. Unlike water in a bath, sea level is not equal around the world. In fact, nothing on earth - not the sea, the shore or the mountains - is stable or constant, so the question of what you measure from and to becomes incredibly tricky. But that hasn’t stopped scientists risking life and fingers to use an ever-evolving array of technologies to find answers.

Join host Marnie Chesterton as she dives into the mechanics of the latest sea level technology, and how it could make a big difference to understanding our unpredictable world.

Focus on Africa - How will new US tariffs affect Lesotho?

We take a closer look at the impact of the newly imposed US tariffs and hear from Lesotho - at 50% it is one of the hardest hit countries. Does the small landlocked country have a backup plan for its industries?

Algeria says it shot down a military drone near the border with Mali, while Mali says one of its unmanned aircraft crashed. The incident comes amid escalating tensions between Algeria and its southern neighbour. So why have the two countries grown apart?

And why are so few wildlife safaris owned and run by black people on the continent? We hear from one Ugandan man who went from being a tour guide, to setting up his own successful safari business.

Unexpected Elements - Oh, Rats!

On World Rat Day, we’re getting ratty! We look at the biology behind the eternal struggle between rats and rat poison, and we hear about rat-on-rat warfare and other forms of pest control.

We don’t play games when it comes to rats, but we know someone who does. Dr Michael Brecht from the Humboldt University of Berlin tells us how he played hide-and-seek with lab rats and what that tells us about the behaviour of play.

On the topic of ‘rat’ behaviour, we are joined by Dr Zach Berry from the University of Southern California to talk about the psychology behind ratting people out in the workplace, testing the loyalty and morals of the Unexpected Elements team.

And speaking of rats in the workplace… we hear a first-hand report on whether African giant pouched rats might just be better staff members than humans when it comes to detecting tuberculosis at APOPO labs.

All that, plus many more Unexpected Elements.
