The global fashion industry contributes to modern slavery, environmental destruction, and unrealistic body images. But there are solutions. People like Professor Alice Payne from RMIT are working towards a sustainable, responsible and circular process that allows those of us who wear clothes to make the best choices for ourselves and the planet.

Watch a movie from the 50s or 60s about the future, and apparently, we should be all wearing silver jumpsuits around now, or coloured PVC. Most of us aren't, but what we are wearing is shaped by a myriad external influences, be they cultural, social, demographic, economic, political, or more.

Dr Madeleine Seys from Adelaide University explains what role colonisation played on fashion in Australia, and why active-wear was already a thing 200 years ago.

No longer just an eye in the sky, drones in the air, sea and on land have changed military strategy forever. The invasion of Ukraine by Russia has killed tens of thousands of soldiers and civilians alike. To the world's horror, international law and expectations have been savagely upended, but to its surprise, the smaller nation has managed to keep fighting.

Dr Oleksandra Molloy from UNSW explains why drones have become the most important weapon on the battlefield, but will never replace their human pilots.

Vaccines work. The science has repeatedly shown what an incredible impact they have had on diseases, especially those mostly caught in childhood. But some people continue to hold out, due to either the fear-mongering of a few, health-system mistakes by governments, or the potential conflict of corporate interests.

Professor Julie Leask AO from the University of Sydney has spent decades finding out how to change their minds.

Nuclear fusion is the holy grail of power production. It is what powers the Sun and all the stars we see in the night sky.

For the past 80 years, scientists have been saying it's been only 30 years away from being perfected. Except now, with the massive projected electricity demands of AI and the scaling back of fossil fuel use, it could be close to reality.

Our guest is Dr Warren McKenzie, Managing Director of HB11, a small Australian company looking to power the world into the future.

"Frankenfoods". Ultra-processed foods formed in factories, not created in kitchens, make up about half of Australians' nutritional intake. Labelling the food we eat correctly while also letting us know what is healthy and what is going to kill us. Eventually. Dr Alexandra Jones from UNSW and The George Institute for Global Health joins us to help understand Where Are We At With Nutrition and Food Labelling?

Spring-loaded false teeth, fish-skin grafts, pig-heart transplants and bionic limbs. Just some of the ways we have repaired, replaced or reengineered the human body. Join New York Times multi-best selling author, all time TED-talk top ten speaker, and all-round entertaining person Mary Roach discussing her new book on the topic, "Replaceable You".

Koalas did not catch chlamydia from humans. Humans can't catch it from koalas either, but we can catch it from birds!

Koala chlamydia often makes people snigger, thinking that the animal symbol of Australia can get what we think of as an STD. But the disease is decimating populations of the fluffy marsupial that are already struggling due to habitat destruction, road deaths and the curse of the feral cat, fox and dog. Not all is lost, however. Professor Peter Timms and his colleagues at the University of the Sunshine Coast in Australia have brought to market the very first vaccine for koala chlamydia. Find out how they first caught the disease, why fact that antibiotics can cure the disease but then the koala can't feed, and why baby koalas eating poop is both good and bad.
