Of all the effects of ageing, perhaps the most dreaded, is dementia. It's confronting for the person, their family, and everyone around them. The common perception is that there isn't much that can be done if you get it. That, however, is probably not true. Tara Jewell is studying this question for her PhD at the University of Canberra. Her work centres around the brain and healthy ageing. In particular, she's looking at personalised nutrition. Tuning nutrition for the individual is a new and pr...

What was the world like ten, twenty or a hundred thousand years ago? What was the environment, the plants, the animals and the insects? And, importantly, how did these mesh into an ecosystem? To answer these questions about deep time, we need, not just sophisticated techniques, but the skill and passion of people like our guests today. Dr Alex Wall and PhD Student Jalen Nalbant are paleoecologists . In this interview by Sophia and Rod, we look at what that means and why it matters today. You can...

Let's start with a big question: what are the pillars of civilisation? There are a few possible answers, but our guests today might argue that the list should include soil. Humble, dirty dirt, crawling with larvae, fungus and bacteria is an under-appreciated champion because, without it, we would not be here. To celebrate the magic of soils, Sophia Dacy-Cole has just submitted her PhD which includes an exhibition that celebrates soil ( Instagram and website ). Joining us is Dr Alex Wall, a paleo...

Image source: https://physics.anu.edu.au/news_events/?EventID=457 One of the joys of science is delving into the deepest mysteries of the universe. What holds it all together? Part of the answer, of course, is gravity. That's the force that allows us to sit or stand without floating off into space. But it's much more than that, because without gravity, there would be no Earth and no Sun. In this episode we enjoyed a conversation with Distinguished Prof Susan Scott from the ANU. Professor Scott i...

A triumph of our civilisation are the things that go on under the covers without us even noticing. When you pour stuff down the sink or flush it down the toilet, where does it go? Luckily, we don't need to think about it...until somebody does the wrong thing. That's when we should hail the invisible, unsung heroes of this story. That's right, these are the people that go down into the bowels - literally - of a city's plumbing to do what must be done. We can do our bit, it's not difficult... thin...

A guest podcast from Valerie Albrecht. This podcast offers reflective space to consider the relationship between sustainability and spirituality. Is there one? Could practising sustainability nurture spirituality? Could practising some form of spirituality help us to live more sustainably? Could spirituality help us to give right place to all that is losing sustainability? Contributors from a cross section of professions and viewpoints share their knowledge, perspectives and wisdoms: a Heritage ...

If you know the term cognitive dissonance , it applies to ability of a person to hold entirely incompatible ideas in their head at the same time. If people can have it, so can a government. Take these two statements: 1) We will work towards a sustainable future 2) We will pursue economic growth The evidence is overwhelming: we cannot do both of these things because economic growth is the antithesis of sustainability. Pasting a veneer over this chasm are terms such as green growth and weightless ...

So it's okay to clear the Amazon jungle? Almost certainly you disagree with that statement, but how do you respond when someone says that to you? In this episode we think about 'that' conversation.

When somebody makes a statement that is foreign to your thinking, how do you react? In this episode, Rod Taylor recounts a conversation with the Brazillian, Fernando. What does it mean to raze the Amazon jungle, why should somebody like him care? Why should anybody care? The answer of course, is that it this cannot be sustained. While we hear that word thrown around so often, we should remember the end point of something that is unsustainable - is literally - the end....

Today's episode should prompt us to ask, how should we measure the success of our society? Is it the growth, consumption, GDP and the size of our armies? Or perhaps it should be about opportunity, the strength of our communities and how we care for people less well off. Michael Bayliss from Sustainable Population Australia looks at what growth is really doing to social equality. Michael invites you to sign the Position Statement on Population .

As Andrew Skeoch says in this episode, there is much we can learn from Nature, if only we sit quietly and listen. Andrew takes that a step further by recording the beautiful songs of birds around the world. And, as he says, it's more than simply enjoying the aesthetics because the birds use their song to build relationships and navigate a shared environment. Andrew is author of Deep Listening to Nature . This podcast is part of the Rethinking Sustainability series....

On page 2 of the newspaper there's a story about melting icecaps. On page 3 there's a full page ad for this week's bargains. Somewhere here there's a disconnect. Meanwhile, shopping is - literally - sold to us as something we should do more of. But does it really make us feel better? Artist and thinker Jeremy Barrett ponders these things as he wanders through his local shopping maul. Jeremy's exhibition of paintings & mono prints is at the Tuggeranong Arts Centre, 2 February - 28 March. The ...

The word "sustainability" has become cliché, loaded with myths, half-truths and outright lies that try to convince us that a few tweaks to ‘business as usual’ will be enough. What then, does ‘sustainability’ really mean? A fundamental problem requires fundamental solutions - yet these are often completely ignored. In this talk at the Conservation Council, sponsored by Sustainable Population Australia , Rod Taylor digs into the themes of the in The Path to a Sustainable Civilisation co-authored w...

We are fortunate to live on a planet that surrounds us with the wonders of nature. From frogs to koalas and even snakes and sharks. Yet what are we to make of the sixth great extinction now underway, caused by humans? Suzanne Ferris' book Let's Not Lose Them: Endangered Species in Australia embodies both the joy of life and a warning that we are unwinding our life support system.
