From the mysteries of space to the secrets of the microbiome, from the science of pain to extraordinary stories of resilience and discovery — 2025 was a year to remember. Join Conor, Dodi and the team as they reflect on the highlights on Discovery Matters.

Brain tumours are among the most complex and challenging conditions in modern medicine. In this episode, we explore what brain tumours are, how they develop, and most importantly, the patient experience.

Discover the story of Dr. Rex Spendlove, the humble scientist behind a breakthrough in cell culture media. From his early days tackling unreliable fetal bovine serum to founding HyClone Laboratories, Dr. Spendlove’s innovations set new standards for scientific research and helped shape modern biotechnology. Join us as we explore how curiosity, collaboration, and a drive to help others can change the world.

What happens when mRNA meets lipid nanoparticles? Sparks fly—and science wins. This dynamic duo is behind breakthroughs from game-changing vaccines to strategies for silencing stubborn viruses.

Join Dodi and Conor as they sit down with Professor Sharon Lewin, a global leader in HIV research, to explore how this partnership could transform treatment and rewrite the future of medicine.

Smart science, big ideas—don’t miss this episode of Discovery Matters, brought to you by Cytiva.

This episode is all about the purisuit to understand and treat metastatic breast cancer. Dr. Martine Piccart and Dr. Lisa Carey delve into the complexities of metastatic breast cancer (MBC), highlighting why it remains one of the most challenging forms of the disease to treat.

We’re fascinated by the microbiome — and for good reason. But how do we protect this invisible ecosystem that plays such a vital role in our health?

From engineering live, programmable therapeutics that disarm dangerous gut pathogens to creating a global “doomsday vault” to safeguard the diversity of human gut microbes, we dive deep into the cutting-edge science shaping the future of microbiome research.

In this episode, we explore zoonotic diseases and their growing impact on global health.

Professor Clare Bryant, sheds light on strategies to vaccinate animals to prevent pathogen transmission into humans. We also delve into the historical context of the disease, the role of vaccines, and the importance of coordinated public health.

Whether you're a public health professional or simply curious about emerging infectious diseases, this episode offers a comprehensive look at the science, challenges, and solutions surrounding zoonotic diseases.

Pain. It comes in many forms: physical and emotional. But do we really understand it?

This episode will attempt to answer fundamental questions about what pain is, how it is experienced, and why it is such a critical aspect of human existence.

We speak with Prof Jeff Mogil to discuss sex differences in pain. His work has been influential in promoting the inclusion of both sexes in pain research, ensuring that treatments and pain management strategies are more effective for everyone. We are also joined by Steve Ruston, CEO of Persica, to discuss non-opioid intradiscal injection to treat chronic low back pain caused by bacterial infection.

Today, we're diving into a topic that's not just reshaping the world of vaccines—it's flipping it on its head. We're exploring the cutting-edge realm of inverse vaccines with Prof Lawrence Steinman and how they're revolutionizing the approach to treating autoimmune diseases. Plus, we'll chat with CancerVax, who are using the immune system in a radically different way, aiming to make it attack cancer cells just like it would fight off a virus like measles.

Ever wonder what happens to your body when you leave Earth behind? In this gravity-defying episode, we launch into the weird, wild world of human biology in space. From the first C. elegans in space to the NASA Twins Study to future deep space missions, we have a lot to discuss. Strap in as we float through the science of space adaptation. Spoiler: space may teach us about our Earth-bound health.
