What happens when the cells of the nervous system, which are called neurons, die? As approximately 86 billion of these cells are found in the brain, spinal cord, and throughout the body, their failure can be devastating. On this episode, we discuss how our nervous system functions like an electrical grid, nature's impact on the nervous systems of the living and the unborn, and where you might first experience signs of neurodegeneration.

Generic pharmaceuticals make up nine out of every 10 prescriptions in the United States and in 2025 drugs for COPD, hypertension, high cholesterol, cancer, and many other disease conditions have expiring patents, so can be produced as generics. These drugs are as effective and work the same as the name brands, but typically cost consumers significantly less. On this episode, we discuss how they're formulated to be effective, how they're scaled from laboratory to manufacturing, and why they're so important in improving access and affordability.

There are potentially billions of different types of bacteria, which are found almost everywhere. Some are friends while others are foes.

In this episode, we discuss the threat presented by antimicrobial resistance, why it's becoming more of a problem, and why there is reason for hope.
