How do painkillers work and which ones are available to us? Why doesn't the plastic on ready-meals melt in the oven? How can we donate platelets instead of blood? How can we ease the pain of arthritis? We take on these questions in this week's show. We also& reveal why omega oils are so good for us, look into how the International Space Station keeps itself movign over earth and investigate the demise of the honeybee.
