Harold Shipman, once seen as a pillar of trust in his community, remains one of the most notorious serial killers in modern history. Over a period spanning more than two decades, he is believed to have murdered at least 215 patients, though some estimates suggest the total may have reached 250. Shipman used his position as a general practitioner to commit these crimes, exploiting the immense trust placed in him by patients, families, and colleagues alike. Central to uncovering the scale of his crimes was the rigorous application of biological evidence, particularly forensic toxicology and pathology, which ultimately exposed the patterns of murder he had meticulously concealed. This podcast explores the biology underpinning Shipman’s detection and conviction, examining how science revealed the truth behind a doctor whose professional authority had become a tool for death.
In this episode, I’m joined by student Sunike, who exploreswhether dental implants are being used too readily as a first-line treatment. She examines the ethical considerations surrounding this trend, the rise of dental tourism, the hidden complications behind implants, and why preserving natural teeth should often come first. Through evidence-based research, and real patient stories, Sunike challenges us to “go back to the roots” of good dentistry.
Ever wonder why hearing an old song or seeing a childhoodtoy can instantly pull you back into a moment that feels both distant and alive? Nostalgia isn’t just sentimentality—it’s a biological and neurological process deeply embedded in the way our brains link emotion, memory, and reward. What feels like a trip down memory lane is, in truth, a carefully orchestrated cascade of neural activity, neurotransmitter release, and sensory reactivation that binds who we were to who we are now. Far from being an indulgent whim, nostalgia is a fundamental biological function that supports mental health, resilience, and the continuity of identity - and this podcast will explore how.
Antibiotic resistance is a rapidly growing global threat, driven by misused medications and the natural evolution of bacteria. Modern technologies such as AI-guided phage therapy and AMR surveillance are opening new pathways to detect, target, and treat resistant infections more precisely. Tackling this crisis, however, requires a unified “One World” approach where countries share data, resources, and innovations to protect human, animal, and environmental health. I'm thrilled to be joined by two of our biology students, Maisie and Tilly who will have conducted and will share their own research into this fascinating subject.
The Titanic, long remembered for its tragic sinking, has transformed into an underwater laboratory, with unique biological and chemical processes actively degrading the wreck. Microbes, including iron-eating bacteria, play a pivotal role in the ship's slow decay, while a new ecosystem of marine life has taken root on the Titanic’s remains. As the wreck continues to disintegrate, it offers researchers invaluable insights into life at the deepest parts of our oceans and the resilience of nature in extreme environments.
The Victorian circus and its infamous freakshows were a curious mix of biological wonder and human exploitation. While many of the individuals displayed suffered from rare medical conditions, their participation often came at a high personal cost. This podcast delves into the ethical and biological implications of these "freaks," questioning whether they were marvels of biology or simply victims of a society that saw them as objects for public amusement.
Mitochondrial replacement therapy (MRT) offers a revolutionary solution to prevent mitochondrial diseases by combining DNA from three individuals, providing hope for families previously doomed by genetic disorders. With successful trials in the UK, MRT stands at the intersection of groundbreaking science and complex ethical considerations, marking a new era in reproductive medicine. As the technology evolves, it promises to reshape the future of genetic disease prevention and human reproduction.
Nuclear disasters like Chernobyl and Fukushima leave morethan just ruins; they cause profound and lasting biological damage that echoes through generations. This episode explores how ionising radiation affects DNA, cells, and entire ecosystems, revealing the hidden costs of these catastrophicevents. From cancer risks to ecological disruption, I uncover the complex science behind the invisible fallout that shapes lives long after the blasts.
Veterinary care has become increasingly advanced, but withprogress has come a steep rise in cost, leaving many pet owners struggling to afford the care their animals deserve. In this episode, I'll explore the real reasons behind high vet bills: from cutting-edge technology and professional training to corporate influence and insurance shortfalls. Join me as I unpack whether veterinary care is truly overpriced...or simply underappreciated.
Behind the bright lights and roaring crowds of contact sports lies a silent epidemic: repeated head trauma and its devastating effects on the brain. From NFL legends and MMA fighters to boxers and pro wrestlers, many athletes have suffered the irreversible consequences of Chronic Traumatic Encephalopathy (CTE). In this episode, I explore the biology, the personal stories, and the urgent need for change in how we protect the minds of those who put their bodies on the line.
There are over 200 different types of dwarfism, with achondroplasia being the most common, affecting one in 25,000 births. Achondroplasia is caused by a spontaneous mutation in the fibroblast growth factor receptor 3 gene that occurs in the developing embryo, resulting in a disproportionately short stature and abnormal growth in the spine and skull. In this podcast, I'm joined by one of my A-Level biology students Ellie, who has conducted research into this fascinating topic. She shares her own her journey with achondroplasia, specifically her experience with limb lengthening, and discusses some of the current treatment options for dwarfism in the UK. Ellie is also joined by author, advocate and founder of the non-profit organisation 'The Little Legs Big Heart Foundation', Kristen DeAndrade, who like Ellie, shares aspects of her jouney with achondroplasia.
From bingeing murder documentaries to tuning in to every new crime podcast, millions are hooked on true crime...but why? In this episode, I explore the surprising biological roots of our obsession, uncovering how fear, empathy, dopamine, and evolution all play a role. It turns out our brains are wired to pay attention to danger, feel for victims, and rehearse survival - making true crime not just compelling, but neurologically irresistible.
From dolphin whistles to parrot mimicry, and even AIprojects decoding whale song, science is beginning to explore what once seemed pure fantasy: the ability to truly communicate with animals. In this episode, I delve into the biology of language, the cognitive abilities of non-humanspecies, and the cutting-edge technologies bringing us closer to cross-species conversation. Could Dr. Dolittle's dream really become reality, or are our brains, and theirs, simply too different?
Memorising facts might get you part of the way in A-Level Biology, but true success lies in understanding how the systems connect, interact, and apply to real-world contexts. In this episode, I unpack why surface-level revision isn’t enough, especially under the AQA exam board...and how students can shift from rote learning to meaningful mastery. With insights into how biology is structured, assessed, andretained, I explore what it really takes to thrive in this demanding course.
From cold chills and flickering lights to full-blown apparitions, tales of ghosts have haunted human imagination for centuries. But what if there’s a biological explanation for these experiences? In this episode, I explore how brain chemistry, sleep paralysis, sensory misfires, and even mould spores might explain the science behind what many believe to be the supernatural.
While some argue that apps and 3D models can replace animal dissection in schools, hands-on anatomical exploration still offers something digital tools can’t. In this podcast, I dive into the value of dissection for learning biology - from exploring real brain and eye tissue to examining the intricacies of turtles and lampreys. I also address the ethical debate and explain why dissection, when done thoughtfully, is a powerful tool for deep understanding.
