Discovery Matters

In this episode of Discovery Matters, we explore the science, stigma, and innovation behind one of medicine’s most misunderstood hormones. We are joined by Shalin Shah, CEO of Marius Pharmaceuticals, to unpack why testosterone plays a foundational role in health for both men and women, how flawed studies and outdated perceptions shaped public opinion, and what it really takes to bring evidence‑based hormone therapies to patients. From regulation and innovation to patient outcomes, this conversation reframes testosterone as a core component of everyday health — not a cultural stereotype.

Global health has hit a low tide, but the story doesn’t end there. In this episode, we revisit Dr. Jerome Kim of the International Vaccine Institute to explore funding cuts, shifting power, and how regions like Africa and Europe are stepping up to reshape vaccine security and pandemic preparedness.

In this episode of Discovery Matters, we explore both sides of the gene‑editing coin: the tools that cut DNA and the technologies that safely deliver them where they need to go.First, we’re joined by Dr. Stephan Riesenberg from the Max Planck Institute for Evolutionary Anthropology in Leipzig, who takes us inside the world of synthetic guide RNAs. Then, we zoom out to delivery and analytics with Adam Crowe, Senior Manager of Nanomedicine Analytical Development at Cytiva. Adam reveals why lipid nanoparticles (LNPs) are both powerful and incredibly complex, and how cutting‑edge analytics are critical for turning promising gene‑editing tools into real medicines.

Kenya has eliminated human African trypanosomiasis —sleeping sickness — as a public health problem. Dr. Gerardo Priotto from the World Health Organization joins us to explain how Kenya met WHO’s rigorous criteria, the science behind the validation, and the partnerships that made this milestone possible. We unpack the challenges of T.b. rhodesiense, the role of surveillance and community action, and what Kenya’s success means for the global fight against neglected tropical diseases.

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.

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.Show notes1.

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.
