    Are ultra-processed foods harming our health?

    What is ultra-processed food? Why do things like sweets and crisps fall under the same ultra-processed label as plant milks and cereals? Produced by and co-hosted with MSc Health Psychology student, Emily McLaughlin, we asked how ultra-processed foods are defined, how they affect our health, and how we’re supposed to navigate our consumption of them. In each episode, we dive into the evidence behind issues that matter to you. Dr Sam Dickens (Research Fellow at UCL) explained the findings from his latest trial testing the impact of ultra-processed and minimally-processed diets on weight and cardiovascular health. Sam talked about using the EatWell guidance, how we need to change food systems instead of shaming individuals’ choices, and he advised that we should ignore diet advice on social media. Resources and recommendations The journal article we discussed: * “Ultraprocessed or minimally processed diets following healthy dietary guidelines on weight and cardiometabolic health: a randomized, crossover trial” by Dicken and colleagues and published in Nature Medicine, link here The headlines covered: * “Ultra-processed food linked to harm in every major human organ, study finds” published in the Guardian, link here Free mental health support: * For urgent mental health support, call Samaritans on 116 123 or contact online here * Access the Mix for support for under 25’s here * To find support and advice or access resources around mental health, access YoungMings here The views and opinions expressed by guests on this podcast are their own and do not necessarily reflect those of the host or The Science or Fiction Podcast.

    Are chatbots making us lonely?

    Not only can we get any question answered at any time, but we can also have human-like conversations without interacting with a single person. AI-powered chatbots, systems like ChatGPT that simulate two-way conversations with the user, are now widely available. Many are turning to chatbots for relationship advice and mental health support - with some saying they find it easier to talk to chatbots than people. Experts are worried about this increasing reliance on non-human interaction. In a recent paper published in the British Medical Journal, researchers raised concerns around people further isolating themselves and pointed out that we do not have a clear understanding of how relying on chatbots for relationship or mental health advice is affecting our well-being. Concerned about his friends and wanting clarity on the evidence, third-year undergraduate psychology student, Ahmad Muntadhar, sought to answer the question: Are AI chatbots making us lonely? In each episode, we dive into the evidence behind the issues that matter to you. We interviewed Arthur Bran Herbener, a PhD student at Aarhus University, about his latest research on whether there is a link between talking to chatbots and loneliness in young people. We also spoke to New York-based therapist and social worker, Shahem McLaurin, to find out what is happening in practice and whether it is safe to turn to chatbots for mental health support. What you’ll find in this episode * Beginning - Kathryn and Ahmad introduce the topic. * 04:06 - Arthur explains what we know about social relationships and AI from the research. * 07:57 - Arthur talks about stigma and why people turn to AI. * 10.46 - Arthur describes the research findings on talking to AI like a friend was linked to loneliness. * 15:19 - Arther explains the evidence around why we need to be vulnerable with other people. * 18:33 - Shahem explains his concerns around using AI for therapy. * 23:06 - Shahem talks about co-dependency and why we need to self-sooth. * 26.05 - Shahem speaks about the importance of maintaining our agency. * 28.51 - Shahem explains why we need to build trust and community with others. * 32:33 - Kathryn and Ahmad reflect on the interview and answer the question: AI chatbots are making us lonely, is it science or fiction? Resources and recommendations The paper we discussed: * Are lonely youngsters turning to chatbots for companionship? The relationship between chatbot usage and social connectedness in Danish high-school students, by Herbener & Damholdt and published in International Journal of Human-Computer Studies in February 2025 The headlines covered in the episode: * Experts raise alarm about people using ChatGPT and other AI systems to help with loneliness, published in the Independent in December 2025, linked here * ‘I spoke to ChatGPT 8 times a day’ - Gen Z’s loneliness ‘crisis’, published by the BBC in January 2026, linked here How to access free mental health support: * For urgent mental health support, call Samaritans on 116 123 or contact online here * Access the Mix for support for under 25’s here * To find support and advice or access resources around mental health, access YoungMings here The views and opinions expressed by guests on this podcast are their own and do not necessarily reflect those of the host or The Science or Fiction Podcast.

    Rewind: Can embracing winter improve mental health?

    It is the first week of February and my alarm has woken me up to another dark, Monday morning. As I make a cup of tea with my eyes half closed struggling against the big light in the kitchen, I’m already dreaming of sunny summer days and dreading the fact that when I get home from work - surprise! - it is going to be dark again. My current mindset is unhelpful: it is only going to make me feel worse. I could shift my perspective. I likely feel sleepy because evidence suggests we need more sleep in winter. I put the big light on to try and force myself awake, but why? I could put on soft lamps and ease myself into the day. In this episode, Leibowitz explains the concept of wintertime mindsets, answers listeners’ questions about ways to feel better in winter, explains some misconceptions about seasonal affective disorder (SAD) and how we can draw from evidence from different settings, daily practices and science to better understand our wellbeing. We hope you enjoy this rewind of “Can embracing winter improve mental health?” - we’d love to hear your thoughts and the small yet meaningful ways you are enjoying winter.

    Can gene therapy cure Huntington's disease?

    Huntington’s disease is an inherited condition that causes neurodegeneration - the progressive loss of neurons in the brain. This can lead to changes in movement, thinking, and mood. Reports of a breakthrough hit the headlines last week: a press release from a clinical trial reported that using gene therapy they have managed to slow disease progression for the first time. Some are warning that it is too early to say we have a cure for Huntington’s given that these results are very early and have not yet been reviewed. What does it mean to treat a neurodegenerative disease like Huntington’s? How is slowing the progression of a disease different from curing it? And what do the results of this trial mean for families living with the condition today? In this episode, we speak with Professor Rachael Scahill, Associate Director of the Huntington’s Disease Centre at University College London. We discuss how Huntington’s affects the brain, what this gene therapy involves, and what these results could mean for the future of neurodegeneration research.

    Is sleep important for the brain?

    Most of us spend about a third of our lives asleep. We feel the effects of a bad night of sleep, waking up groggy and turning to caffeine to get through the day. While we might think that our sleep habits have a strong influence on brain health, the evidence is not so clear. There is a lot of advice out there on how to get a good night’s sleep, as well as reports about the consequences of poor sleep. But sleep doesn’t look the same for everyone: age, sex, gender, and culturecould influence sleep patterns. Why do we sleep? What does “good sleep” mean for different people? And how does sleep affect brain health? In this episode, we interviewed Professor Anders Fjell, sleep expert and Professor of Cognitive Psychology at the University of Oslo to answer these questions. This episode is the second of our neuroscience series, produced by PhD student Chloe Carrick, Youth Advisor Anushka De, and Research Fellow Dr. Kathryn Bates.

    What is a brain-computer interface, and can it read your mind?

    Brain-Computer Interfaces, or BCIs for short, are all over the news (like here and here). These systems – which can be implanted into the brain – have the potential to help people with neurological conditions control devices (from mobile phones to robotic arms) using only their thoughts. Headlines often use futuristic terms like ‘mind reading’. These phrases might grab our attention, but they could also distort our understanding of what BCIs are capable of (and what they are not). In this episode, we interviewed Dr. Hunter Schone, BCI expert and post-doctoral researcher at the University of Pittsburgh. We discussed what a BCI looks like, how they can help patients with severe clinical disorders, and the roles of universities, companies, and regulators have in their development. We also discuss the work that needs to be done before these devices are made more widely available for patients. This is an episode to watch: from 09.42 you’ll see our jaws DROP when Hunter pulled out a 3D model of a patient’s brain to demonstrate how BCIs work!

    How do we address inequalities in chronic pain treatment?

    In this second episode of our two part series on chronic pain, we spoke to Misha Gardner to discover how healthcare providers can address the structural bias and inequalities to better support people with chronic pain. The PEACs (Pain: Equality of Care and Support in the Community) programme was co-designed with Black people to develop a person-centred and bio-psycho-social approach to treating chronic pain in diverse communities. Black women are twice as likely to experience chronic pain than white women, and less likely to be referred to tertiary care. The PEACs programme was developed with Black communities to ensure better support, empowerment, and improved quality of life for people living with chronic pain. In this episode, produced by Trainee Clinical Psychologist, Mariam Shah, and Research Fellow, Dr Kathryn Bates, we find out why Black people face inequalities in chronic pain treatment, how healthcare programmes can be developed with communities and for communities, and we learn about the outcomes and next steps for the programme. There are important insights for healthcare providers, clinical psychologists, and those living with chronic pain or interested to find out more. Make sure you stay till the end to find out the impact of the programme. The first episode of this two part series on what it means to live with chronic pain can be found here.

    What does it mean to live with chronic pain?

    What is chronic pain, and why is it different for different people? How do we begin to treat chronic pain? If my pain fluctuates, what can I do about it? We answer these questions and more in our latest episode. This is the first of two episodes about chronic pain, produced by Trainee Clinical Psychologist, Mariam Shah, and Research Fellow, Dr Kathryn Bates. In this first episode, we interviewed Dr Anna Hood, Lecturer at the University of Manchester and expert in the biological, psychological and social challenges experienced by young people living with chronic pain. This eye-opening conversation reveals how individuals experience chronic pain, as well as the structural and social barriers many people face when they are trying to seek help. We discuss how chronic pain is defined, why people feel they need to hide their chronic pain, and how a better understanding of the complexity of chronic pain and the bias present in healthcare could improve access to support.
