How do cells move cargo with such precision? What controls vesicle trafficking, and why does this process shape everything from cellular communication to disease? And what can extracellular vesicles really reveal about health, aging, and neurodegeneration?

In this episode of Neuroscience and Beyond, Professor Randy Schekman, Nobel Prize Laureate in Physiology or Medicine, helps unpack these questions. He explains the molecular machinery behind vesicle trafficking, how these pathways were discovered through foundational cell biology, and how this research enabled breakthroughs like insulin production in yeast. Prof. Schekman also explores what extracellular vesicles carry and why interpreting their biological roles remains experimentally challenging.

The conversation then shifts to Parkinson’s disease; its complexity, why current treatments mostly manage symptoms, and why early cellular changes may begin long before diagnosis. Prof. Schekman highlights research on genetic risk, environmental factors, and emerging evidence that vigorous exercise may influence disease progression.

In this episode, you’ll learn about:

• How vesicle trafficking and extracellular vesicles shape cellular communication
• The cell‑biology foundations behind technologies like insulin production
• Why Parkinson’s disease is so difficult to treat and detect early
• Genetics, early warning signs, and the role of exercise in Parkinson’s research

Why is Alzheimer’s disease so difficult to treat and how is the brain’s immune system involved?

Professor Michael Heneka, Director of the Luxembourg Centre for Systems Biomedicine, joins us to discuss key topics in #neuroinflammation and Alzheimer’s disease.

We explore how inflammation shapes the progression of #neurodegeneration, why detecting Alzheimer’s early remains a challenge, and the surprising biological world of tunneling nanotubes-tiny bridges that let cells exchange materials and signals.
Professor Heneka also breaks down emerging strategies in #prevention, #personalizedmedicine, #genetherapy, and anti-inflammatory approaches that could redefine the future of Alzheimer’s #treatment.

In this episode, you’ll learn:
• Why Alzheimer’s is so complex and why traditional #treatments struggle to stop its progression
• How #neuroinflammation drives the disease, reshaping the #brain long before symptoms appear
• How early #biomarkers can reveal Alzheimer’s up to 10 years in advance, improving detection and intervention
• The future of personalized Alzheimer’s #treatment, from #genetics to targeted #immunotherapies
• How tunneling nanotubes and #immune pathways may transform our understanding of #neurodegeneration

What happens in our brain when we crave revenge - and how can forgiveness set us free?

In this powerful conversation, we speak with James Kimmel Jr., a former lawyer, and currently an assistant clinical professor at the Yale School of Medicine, and author of The Science of Revenge, about the psychology and neuroscience behind revenge, addiction, and forgiveness.

Drawing from his own story of childhood bullying and near-violence, Kimmel explains how these experiences led him from a 20-year legal career into neuroscience research and the creation of the Yale Collaborative for Motive Control.

In this episode, you’ll learn:
- Why revenge feels so satisfying - and why it’s addictive
- What happens in your brain when you crave revenge?
- Why does your self-control system shut down when anger takes over?
- The surprising difference between men and women when it comes to - empathy during acts of retaliation.
- How to turn revenge into healing through the “Courtroom of the Mind,” an evidence-based mental exercise that helps release anger safely.
- The transformative power of forgiveness and empathy
