The edge of life: Cell membranes, diffusion, and transport.
What does walking, growing plants in dry environments, or making most of our ATP have in common? They all rely on transport across their membranes. Cellular membranes form the barrier between life and the outside world acting as the gatekeeper to cells. In this podcast, I explore how the structure of cellular membranes allows cells to regulate the movement of substances by diffusion, facilitated diffusion and active transport.

The Chemistry of Life
Don't fear the chemistry! Life is the result of chemical reactions breaking down and making new chemicals. While many of us fear chemistry, a little chemistry knowledge can go a long way into understanding how we work and understanding some of the basics behind nutrition. In this podcast, I introduce the most important types of molecules used for life without getting too technical.
