Science Friction's latest series is: Brain Rot. We're looking at what being chronically online is doing to our brains. What's really going on with our attention spans and tech addiction? Is data-dumping your entire life into ChatGPT helpful? Can going internet free help you escape the doomscroll? And what's it like to be in love ... with an AI?

National technology reporter Ange Lavoipierre tackles the wildest ways people are using tech and the big questions about our own use. That's Brain Rot — our latest series from Science Friction.

Science Friction's previous series was: Cooked. We dig into food science pickles. Why are studies showing that ice cream could be good for you? Do we really need as many electrolytes as the internet says? And why are people feeling good on the carnivore diet?

What family secrets lie deep inside your cells? A story of survival against the odds, hope after the Holocaust, and the eye-opening new science of epigenetics… Can biology help you transcend the traumas of your ancestors, or forever burden you with their legacy?

What family secrets hide inside your cells? Epigenetics, trauma, and ancestry

For Science Friction, a new series — Cooked!

On Cooked, we dig into the nuance of nutrition. Why are studies showing that ice cream could be good for you? Do we really need as many electrolytes as the internet says? And why are people feeling good on the carnivore diet?

Nutrition and food scientist Dr Emma Beckett helps comb through the evidence on food groups and ingredients like meat, dairy and salt — to unpick why nutrition studies can be so conflicted and confusing.

00 | INTRODUCING — Cooked

Two decades ago, nutritional epidemiologists made a startling finding – that people eating more ice cream were less likely to develop diabetes.

In the years since, various groups have tried to account for this peculiar scientific signal — with limited success.

In multiple studies the link between ice cream and a reduced risk of diabetes persists. Yet nutrition experts globally still aren’t convinced.

But if it’s not true, what’s causing the signal?

Grab a spoon and dig into culture, causation and confounders — and the joy of a tub of ice cream.

01 | Cooked: Could ice cream actually be good for you?

Diets like carnivore have been popping up all over the place. People who go carnivore aim to eat nothing but a select few animal products, like meat and eggs.

So why are some people turning to an all-meat diet? And why do they say they feel good doing so?

On this episode of Cooked, we sift through some of the counterintuitive findings around carnivore — the scientific pitfalls you need to be aware of when reading the research — and the health effects in the short and long term.

It was one of the world's biggest nutrition trials. A study of thousands of people which found that following a Mediterranean diet could meaningfully reduce someone's risk of heart disease and stroke.

But as data detectives began to comb through the results of the trial, something wasn't quite adding up.

On Cooked this week, we're taking a look at what can go wrong when implementing a nutrition science trial at scale ... and what it means for one of the world's most popular diets.

04 | Cooked: A peculiar potato experiment

Over the past few years, you might have heard advertisements in your podcast feed or on social media for electrolyte supplements.

If you haven’t seen them, they’re basically these little sachets or tubs that get mixed in with water as a drink.

News media reports demand for such products is exploding – with the market for electrolyte supplements set to grow to 112 billion dollars by 2030, more than doubling in size in less than a decade.

They go by a bunch of different names … and their marketing often suggests we could all use more electrolytes in our life.

But what’s the science on this swing towards salty beverages? Who actually needs them? And what does our obsession with optimised hydration … say about us?

For episode six of Cooked, we turn the lens on … science communication itself.

We’re looking at how information travels from a scientific study to the world and what can go wrong along the way.

This is the final episode in our Cooked series. We'll be back in May for another series of Science Friction on a different topic — digital devices and how they're driving us to delight ... and to despair.

For Science Friction, it's Brain Rot — a new series about the science of being chronically online and what it’s doing to our brains.

What's really going on with our attention spans? Is data-dumping your entire life into ChatGPT helpful? And what's it like to be in love ... with an AI?

National technology reporter Ange Lavoipierre tackles the wildest ways people are using tech and the big questions about our own use. Episode 1 is out Wednesday 4 June.

INTRODUCING — Brain Rot

Everyone seems to have a hunch that their phone is destroying their attention span, but is there any science to back it up?

In episode one of Brain Rot, we’re doing our best to focus on the topic of attention for a full 25 minutes — and find out what's actually happening in your brain every time your phone buzzes or dings.

Is brain rot a real thing? Or just another moral panic?

And how do you know when your own screen use has gone too far?

Brain Rot is a new five part series from the ABC’s Science Friction about how tech is changing our brains, hosted by Ange Lavoipierre.
