In this episode of Tiny Show and Tell Us, a listener on “team wasp” writes in with some interesting info on USDA wasps for pesticide-free pest control and we learn about some wasp versus beetle drama. Then we talk about how our red blood cells use and expel iron, and how a huge percentage of the iron we get is from broken down blood cells.
