Alisha Wainright: On the new season of When Science Finds a Way…
Haleema Shakur-still: We went in believing something and the result shocked us into learning even more.
Tom Grylls: I think one way to put it is, it's like the emergency brake that we can pull on climate change.
Miranda Wolpert: The potential for AI to scale interventions, to be able to reach millions of people across the world, is enormous.

Transcripts are available for all episodes. New episodes are released weekly.
Carbon dioxide is often seen as the main driver of climate change. But other pollutants are responsible for roughly half of global heating. Host Alisha Wainwright explores the role of “super pollutants” and how reducing them could help slow climate change and improve health.
Tuberculosis has affected humans for thousands of years. But today, drug-resistant TB is creating new challenges for doctors and researchers. Host Alisha Wainwright explores the global fight against drug-resistant tuberculosis.
Extreme heat is becoming more common around the world. While its physical dangers are well known, scientists are only beginning to understand its effects on mental health. Host Alisha Wainwright explores the growing research linking rising temperatures and mental wellbeing.
People around the world are living longer than ever before. But how can we ensure those extra years are healthy ones? Host Alisha Wainwright explores the science of ageing and how growing knowledge could lead to more personalised approaches.
We often think about food in terms of physical health. But what role could diet play in mental wellbeing? Host Alisha Wainwright explores the science linking nutrition and mental health.
Postpartum haemorrhage is one of the leading causes of maternal death worldwide. But an overlooked drug is helping change that. Host Alisha Wainwright explores the story of tranexamic acid (TXA) and how it is now saving thousands of lives after childbirth.
Brain invading fungi might sound like science fiction, but they are a real-world health threat. Host Alisha Wainwright explores Cryptococcal meningitis, the leading cause of death from fungal disease worldwide.
AI chatbots and apps are increasingly being used for mental health support. But could these new tools carry hidden risks? Host Alisha Wainwright continues her exploration of AI and mental health, looking at how to stay safe when seeking help digitally and the challenges posed by unregulated tools.
Artificial intelligence is starting to reshape mental health care. Host Alisha Wainwright explores how researchers are using AI to better understand patients’ needs and support treatment decisions.
The Covid-19 pandemic exposed a deep inequality: Africa manufactured less than 1% of the vaccines it used. But efforts to change that are accelerating.
Alisha speaks with Dr Delese Mimi Darko about the rise of vaccine manufacturing across the continent, and with the team at Biovac in South Africa, developing an Oral Cholera Vaccine with end-to-end production in sight. It’s a powerful story of collaboration, innovation, and the urgent drive for equity in global health.
Alisha meets Professor Pete Scarborough and Jo, a participant testing a new digital tool to support sustainable food choices. Together, they explore how science and technology can help us navigate the complexities of global diets, and make healthier, climate-friendly eating possible worldwide.
Young people face a growing mental health crisis, but effective treatments remain limited. Alisha and Professor Vikram Patel explore a school-based trial in India testing POD (Problem Identification, Option generation and Do it), a practical approach helping students tackle problems head-on. With counsellor Bindiya Chodankar and researchers adapting the model for universities, this episode asks: can simple, accessible tools reshape youth mental health?
Hierarchical Phase Contrast Tomography (HiP-CT) is a new imaging technology that allows entire human organs to be scanned in 3D, in unprecedented detail. Alisha speaks with the researchers who pioneered this innovation, uncovering what it revealed about Covid-19 and what it could mean for the future of medicine.
From malaria to dengue, climate change is reshaping patterns of infectious disease. But could the same data that tracks our warming planet help prevent future outbreaks? Alisha meets researchers using climate models and local insights to map where diseases are likely to spread, turning prediction into a powerful tool for global health.
Alisha speaks with Dr Aimee Grant about ‘Autism: from Menstruation to Menopause’, a groundbreaking study led entirely by autistic people. With input from a neurodivergent Community Council, the project is gathering vital data across the reproductive life cycle to design tools that make healthcare more inclusive and accessible.
From singing to painting, creative outlets have long been linked to better mental health. But how can we harness their therapeutic power in practice? Alisha meets Professor Daisy Fancourt, whose research is establishing the arts as a key ingredient for wellbeing, alongside diet and exercise.
Hearing voices is a challenging symptom of psychosis that treatments have often failed to address effectively. AVATAR therapy is a remarkable approach that could help patients engage with distressing voices and regain control. Alisha meets Dr Vaughan Bell to explore the therapy's potential, talk about findings from the latest clinical trial and hear a personal story of transformation.
Genomics has revolutionised cancer research, offering new hope for cancer diagnosis and treatment. But there are challenges ahead. Alisha is joined by Dr Peter Campbell and researchers Dr Solomon Rotimi and Sara Gómez Trillos to discuss the breakthroughs and the issue of ensuring fair access to advancements for patients worldwide.
Alisha sits down with Professor Iruka Okeke to talk about the factors driving cholera's spread and the innovative mapping techniques being used in Kenya to identify hotspots.
Alisha is joined by Dr Flor M Munoz, a global expert in maternal immunisation to discuss a new vaccine trial, safety considerations and the future.
As rising temperatures challenge vulnerable regions, could ‘cool roofs’ be the affordable, sustainable solution? Alisha joins Dr Aditi Bunker to talk about the remarkable health benefits uncovered in Burkina Faso's trial. Hear firsthand accounts of how this simple intervention significantly reduces indoor temperatures, lowers heart rates and improves overall health.
Alisha meets Dr Jonathan Roiser and his team of researchers to uncover insights from a groundbreaking pilot study exploring brain activity during exercise, including how it could transform the diagnosis and treatment of conditions like depression.
