Would you let robots care for your grandparents?

Would you want a robot to look after you in your later years? What if it treated you like a child? That’s exactly what’s happening to some older people subject to an influx of high-tech solutions to a struggling aged care system in Australia. Our population is ageing and staff are burning out, so tech companies are trying to enter the space with their own 'fixes.’ But what if these technologies are just solutions looking for a problem? Associate Professor Barbara Barbosa Neves is a sociologist of technology who says this is all too common. When older people are excluded from tech design, the technology simply doesn’t work for them. It might be difficult to use, but it can also have adverse effects, like furthering stereotypes and deepening loneliness. She explains how inclusive design – as well looking at the bigger picture – can make a real difference. +++ The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

Humans are constantly getting better at fighting cancer. Our understanding of the suite of diseases is more robust, our technology is more advanced, and our public health systems are more efficient. But cancer epidemiologist Professor Karen Canfell says Australia will still see more and more incidences of cancer over time.   But Australia’s also on track to become the first country to eliminate cervical cancer, the fourth-most common cancer in women. Karen says that our fight against cervical cancer can teach us how to beat other diseases, too. Crucially, it can also teach us how to help our closest neighbours: cervical cancer is low on Australia’s list of most deadly cancers, and yet it’s at the top of the list in Papua New Guinea.  Karen explains why Australia’s leading the world in this space, and how that gives us a responsibility and opportunity to help improve public health worldwide.   +++  The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

Our growing population has a huge number of impacts, but the simplest and most pressing is that we have more mouths to feed than ever before. At the same time, though, climate change is threatening farmland worldwide. That means crops like wheat, which account for 20% of daily calories consumed worldwide, are plateauing. Enter: Richard Trethowan and the Plant Breeding Institute. Richard and his team are working on something called hybrid wheat, which will be more robust and productive than the regular plant. They’re trying to make food that’s healthier, easier to grow, and that will feed more people. Richard explains why we’ve never been able to make hybrid wheat before, why it’s so crucial to the future of our planet, and how over a century of forward-thinking research has laid the foundation for the work he’s doing today. +++ The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

Professor Greg Neely says pain is a good thing. This might worry you when you find out he’s studying some of the deadliest snakes on the planet, but it’s all about trying to understand pain as a mechanism – and Greg’s long-term goal is to address chronic pain, which afflicts more than one billion people. After studying infectious disease at the start of his career, Greg’s been obsessed with pain as the body’s first immune response, but pain is poorly understood. So, he’s seeking out animals that cause severe pain with their venoms to learn how our bodies respond. Along the way, he’s also finding cheap and accessible solutions to snake bites, and investigating old potatoes... +++ The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

We’re told to eat better, sleep more, train our bodies and our brains — all in the name of ageing well.   But how much of that advice is actually backed by science? How might we all live – and stay – well, for longer, at any stage of life? And how much of ageing is really up to us?  Researcher Gilbert Knaggs, neuroscientist Eleanor Drummond, and clinician Olivier Piguet join together to demystify the science from the pseudoscience and bring fresh insights and evidence, unlocking our understanding of healthy brain ageing.  +++  The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

What if the cure everyone’s waiting for already exists — but patients can’t access it?  With AI transforming medicine, breakthroughs are no longer science fiction. They’re happening now.

Australia has more homes per adult than at any point in our history. So why is our housing crisis worse than ever?  Professor Nicole Gurran’s been studying housing for 15 years, and she says the solutions to Australia's housing crisis are obvious – it’s the execution that’s failing, and most Australians are being distracted by media and politicians.  Nicole explains why "cutting red tape" won't solve the problem, why  more than a million Australian households are living in housing stress, and what happened when government funding for social housing fell off a cliff in the mid-90s.  +++  The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

What if the simple act of tapping your card could put your identity at risk?  Every day, we trust encryption to protect our money, data, and digital lives. But quantum computers are advancing fast, and soon they could crack today’s security in seconds, making our current “digital locks” obsolete.  So how do we protect ourselves in a quantum world?  On this episode of The Solutionists, host Mark Scott explores the race to reinvent cybersecurity for the quantum age.  He speaks with leading mathematician Nalini Joshi, 2025 NSW Scientist of the Year, who’s bringing together some of the world’s brightest minds to develop new forms of encryption powerful enough to withstand quantum computing. She explains why maths is central to our digital future, and how mathematical thinking can unlock entirely new possibilities.  Plus, PhD researcher Prachi takes us inside a quantum control lab for a rare glimpse of a quantum computer in action.  +++  The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

"I can't just grab my keys and leave the house. I have to make sure I have something with me in case my glucose levels go too low. I have to make sure that I have spare insulin pump consumables. There's lots of parts of having type one diabetes that isn't just what we eat."  Michelle's lived with type 1 diabetes for 31 years. She has to plan everything: what she eats, when she drives, whether she can try new foods. Sophie, diagnosed as a teenager, spent years hiding her condition, injecting herself in secret in her school bathrooms.  For the millions living with type 1 diabetes, insulin is lifesaving. But it's also relentless. Multiple daily injections, or a pump worn 24/7, and constant vigilance of everything from how you exercise to how hot it is on a given day.   Professor Victoria Cogger is working on something scientists long thought impossible: smart insulin delivered orally as a single daily pill.  Victoria explains how oral delivery could make insulin management much easier, what's made oral delivery so difficult thus far, and what exactly makes this new pill ‘smart.’  +++  The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.

Walk down the cereal aisle. Pick up a box of cereal. The front says "real nourishment" and shows a 4.5-star health rating. Flip it over. It's 25% sugar, packed with emulsifiers, flavors, and protein isolates – it’s full of ingredients you probably can’t even pronounce if you’ve ever heard of them before.  Welcome to Australia's national diet: ultra-processed.  Associate Professor Phillip Baker is the co-lead of a major Lancet series on ultra processed foods, one of the biggest global health challenges of our time.   He says over half of what Australians eat is now ultra processed, and our diet is linked to obesity, type 2 diabetes, inflammatory bowel disease, cardiovascular disease, certain cancers, and mental health problems.  Phil explains why these foods are why these foods are so ubiquitous now, examines what they’re doing to our health, how policy needs to change to protect real food, and how individuals can fight back with their forks.  +++  The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.
