What happens when our body clock falls out of sync with the demands of modern life? In this episode, Matthew Flinders Professor Sean Cain discusses the science of sleep and circadian rhythms, exploring how light, daily routines and our internal biological clock influence when we sleep, how alert we feel and our overall wellbeing. The conversation also examines the effects of disrupted sleep patterns and what research can tell us about creating healthier rhythms for work, rest and everyday life.

In this episode, we sit down with Professor Jay Horvat from the University of Newcastle and the Hunter Medical Research Institute (HMRI) to discuss why lung health is fundamental to overall wellbeing and how emerging research is uncovering surprising new influences on respiratory disease.

Professor Horvat explains the challenges faced by Australians living with asthma, chronic obstructive pulmonary disease (COPD), and particularly those managing both conditions at the same time.

We explore groundbreaking research investigating how the body's metabolism - including factors such as blood sugar levels, cholesterol and excess abdominal fat - may contribute to lung inflammation and breathing difficulties. Professor Horvat discusses how a better understanding of these connections could lead to new treatments, lifestyle interventions and improved outcomes for people with chronic respiratory disease.

GLP-1 receptor agonists have become some of the most talked-about medications in recent years. You may have heard names such as liraglutide, semaglutide (Ozempic and Wegovy), and tirzepatide (Mounjaro). These treatments have attracted attention because they can significantly reduce appetite and support weight loss while also helping to manage blood glucose levels.

The breakthrough came when researchers developed long-acting versions of hormones naturally released by the body after eating, including GLP-1 and, in some cases, GIP. These hormones help regulate hunger and promote feelings of fullness. While the body's natural response lasts only a short time, modern medications extend these effects for up to a week with a single injection.

Since results from major clinical trials emerged in the early 2020s, GLP-1 therapies have transformed obesity treatment, delivering weight-loss outcomes that surpass those achieved by previous medications and offering new hope for people struggling with weight management.
