    6.5 How Ultraprocessed Foods Rewire the Brain with Arsene Kanyamibwa

    Diet and obesity research has shifted dramatically over the past few decades, and ultraprocessed foods have taken center stage. In this episode of The Science Basement podcast, we sit down with Arsene Kanyamibwa from the O’Brain lab at the University of Helsinki to unpack the evolving world of diet, obesity, and nutrition. Join us as Arsene shares the story behind his research - from creating a specialized food picture bank that helped inform eating habits across Finland, to revealing the startling ways ultraprocessed foods impact structural brain composition. Arsene Kanyamibwa is a PhD researcher at the University of Helsinki whose work focuses on investigating how macronutrient content and composition affect food choice, reward processes and their underlying neural mechanisms in diet and obesity.

    6.4 Inside Muscle Recovery: The Science Behind Repair, Strength, and Ageing

    Episode 6.4 of Science Basement: Inside Muscle Recovery: The Science Behind Repair, Strength, and Ageing Have you ever wondered what actually happens inside your muscles after a workout? Why does recovery feel different over time, and what changes as we age? In this episode of The Science Basement, we sit down with Swetha Gopalakrishnan to explore the biology of skeletal muscle and the stem cells that drive its repair and regeneration. From understanding different muscle types to uncovering how “dormant” stem cells activate and make decisions, we dive into the cellular mechanisms that shape muscle function. We also discuss how metabolism influences stem cell behaviour, what happens during muscle injury and recovery, and whether exercise can influence stem cell populations. Beyond the science, Swetha shares insights from her journey from academia into entrepreneurship, and how research can be translated into real-world impact. Swetha Gopalakrishnan is a senior scientist working with Prof. Pekka Katajisto at the Faculty of Biological and Environmental Sciences. Her research focuses on skeletal muscle stem cells, their regulation, and their role in tissue regeneration.

    6.3 The Science of Conversation

    Have you ever wondered what actually makes a conversation flow or fall apart? Why do some interactions feel effortless, while others feel awkward or draining? In Episode 6.3 of The Science Basement, we sit down with Ville Harjunen from the Interaction Analysis Lab to explore the hidden science of human conversations. From subtle cues like nodding and backchanneling to brain activity and attention, Ville’s research uncovers the moment-to-moment dynamics that shape how we connect with others. We also explore how factors like personality, culture, and even video calls influence the way we communicate, listen, and respond. Ville Harjunen is a researcher at the University of Helsinki whose work focuses on understanding social interaction through a combination of behavioral analysis, psychophysiology, and neuroscience.
