Here's an interesting story about a relatively new line of research. According to a study conducted by the new founders of Oxford Biomaterials, silk produced by a certain type of silkworm (Antheraea peryni) can be used to provide a surface for spinal nerves to regrow. The silk disappears over time so that no surgery is required to remove the material. With other researchers working to urge nerve regeneration, having a surface where new nerves can develop becomes more imperative. And on that note, avoiding repeated invasive surgeries is no small thing, either.
