Would you like to live forever? Only 20% of people say yes.

Professor Miroslav Filipović - astrophysicist at Western Sydney University and one of the rare scientists to have observed Earth from above its atmosphere aboard NASA's SOFIA mission - reveals the invisible force quietly placing an expiry date on every human life: cosmic rays. His team also discovered a particle carrying more energy than a thousand trillion light bulbs, and a perfectly circular mystery object in space that had the world whispering "aliens."

From the science of ageing to NASA's return to the Moon, the US-China space race, and Australia's hidden role in global astrophysics - this is where health meets the cosmos.

What if a single tick bite could change the way your body reacts to food forever?

In this episode, Nina sits down with Professor Sheryl van Nunen, the ground-breaking clinician who first uncovered the link between tick bites and mammalian meat allergy, now known as alpha-gal syndrome.

Professor van Nunen breaks down how this condition was discovered, why reactions to red meat are delayed, and how symptoms can escalate from gut pain to life-threatening anaphylaxis. She unpacks the immune mechanisms behind alpha-gal, explains why large local tick reactions matter, and reveals why some meats are riskier than others.

We also dive into what every clinician and patient needs to know right now, from evolving diagnostic tools and warning signs, to prevention strategies and the growing public health implications of tick-related disease.

If you eat meat, live in tick-prone areas, or work in healthcare, this is an episode you don’t want to miss.
