Animal Research: Bad Science, and A Broken System: A Former Lab Researcher Speaks Out | Ep18

What if the system we rely on to develop life-saving medicines is fundamentally flawed, causing immense animal suffering while failing to produce reliable results for humans? In this powerful episode of Puppies, Pandemics, and Public Health, Dr. Johnny Lieberman speaks with Dr. Emily Trunnell, Director of Science Advancement and Outreach at PETA. A former neuroscience researcher who conducted experiments on rats and mice during her PhD, Dr. Trunnell reveals the shocking realities of lab animal research  from dehydrated rats dying due to basic care failures and rats being forcibly intoxicated while lab workers joke about it, to Institutional Animal Care and Use Committees (IACUCs) acting as little more than rubber stamps. You’ll hear why more than 90% of drugs that pass animal tests still fail in human trials, the massive reproducibility crisis in animal research, species differences that make translation unreliable, and exciting non-animal methods (like organs-on-chips and AI modeling) that are already proving more human-relevant. This episode exposes a broken, self-regulated system and highlights the momentum toward modern, animal-free science that could accelerate medical progress while reducing harm. Top 3 Takeaways: The Animal Research Oversight System Is Broken and Self-Regulatory IACUCs are dominated by animal researchers who “police themselves.” They check minimal boxes under the Animal Welfare Act (which excludes 95–99% of animals like mice and rats), rarely question justifications for pain or multiple surgeries, and provide almost no real protection. Animal Experiments Are Poorly Reproducible and Rarely Translate to Humans Up to 89% of preclinical studies cannot be reproduced. 95% of drugs that succeed in animals fail in human clinical trials due to vast species differences, unnatural lab conditions, and publication bias that hides negative results. Modern Non-Animal Methods Are Superior and Already Available Technologies like organs-on-chips, organoids, and AI-driven in silico modeling use human cells and biology, deliver faster and more accurate results, and can replace animal tests  with agencies like the FDA now actively working to make animal testing the exception rather than the rule. About the Guest: Dr. Emily Trunnell Dr. Emily Trunnell graduated Magna Cum Laude from the University of Georgia with a degree in Nutrition Science and earned her doctorate in Neuroscience from the University of Georgia in 2016. She is currently the Director of Science Advancement and Outreach at PETA, where she works to modernize science policy, scientific publishing practices, and university education to support the transition to animal-free research methods. A former animal researcher who conducted experiments on rats and mice during her PhD, Dr. Rinne lives with a passion for advancing human-relevant science that benefits both people and animals. 🔗 Learn more: scienceadvancement.org. About the Show: Puppies, Pandemics, and Public Health explores the intersection of animal welfare, public policy, and human health. Hosted by Dr. Johnny Lieberman, each episode invites changemakers, legal experts, and health advocates to shed light on what really impacts our communities and what we can do about it. About the Host: Dr. Johnny Lieberman is a physician, public health advocate, and lifelong animal lover with a passion for connecting the dots between animal welfare, human behavior, and the systems that shape our lives. With a background in both medicine and public health policy, Johnny brings a unique lens to conversations about how our treatment of animals impacts human health, the environment, and social justice. In Puppies, Pandemics, and Public Health, Johnny brings warmth, curiosity, and a dash of wit to tough conversations that matter. From exposing the realities of factory farming to uncovering the links between zoonotic diseases and our food systems, his goal is to empower listeners to be informed, compassionate, and engaged citizens while still keeping it real (and sometimes bringing in puppies). Whether he's discussing legislative loopholes or snuggling his rescue dog between recordings, Dr. Lieberman believes that creating a healthier world starts with how we treat its most vulnerable beings.
